I presume you might have set the dimmer for the Front LED Display panel too low and hence you can't see any light.

I assume that it plays, you just can't see the display. It may just need a new display bulb, that back lights the display.

Please help.. my monitor has no display and my don't even beep. the LED in the monitor turns back to orange after few seconds. cpu, disk drives and ram are working..


This is one of the serious problem that arises because if you set your monitor with a high resolution with high frequency, then the monitor doesn't display anything as it's frequency is out of the rang or limit of the monitor's actual resolution capacity. Each monitor will have a limit of max frequency that is said to be the Refresh rate (for each and every resolution setting the display is refreshed.) When high resolution is set with high frequency that is not supported by the monitor, it then display a message like "frequency out of range". If you press ESC key within the few seconds of this setting, it will revert back to its initial resolution. But if you continued with the setting of same High resolution with High frequency, the monitor is not going to display anything because its frequency is out of the range. Most of old monitors like CRT's etc doesn't support 1024×768 at a refresh rate greater than 60Hz.

Dometic Americana RM2852 refrigerator does not work. Has power to it, light inside works and lights at top indicating 'AUTO' mode are illuminated, but refrig doesn't work in any mode. Gas is...


Have the same unit but experience no problems. Sounds like a freon leak has left it inert. You can of course switch from auto to gas and eliminate the auto switch over as part of the problem. You can see the gas flame in the outside access hatch, (or maybe hear it) to be sure it is getting gas. since it doesn't respond in auto, which would also work in electric mode, I think it is the freon problem.

Im trying to program my Pro-70 Hyperscaner


To program a known frequency into your PRO-70:

- Press PGM. PGM appears on the display, indicating that the scanner is in programming mode.
- Enter the number of the channel that you wish to program (1 - 50), then press PGM again. As an alternative, press PGM repeatedly until the desired channel number appears on the display.
- Enter the desired frequency, including the decimal (for example, 156.045).
- Press E/L-OUT to store the frequency.
- Repeat steps 2 - 4 to program another frequency.

Your scanner's operating manual has details on other programming steps. If needed, you can download/print the manual here:

Wanted manual realistic 2010scanner


The realistic 2000 series scanners do not have a "VFO" (variable frequency occilator) in the true meaning of the sence. This basicly means that they can only scan the channels or memories that you have programmed.

You can however set a low frequency (like 144 Mhz) and a high frequency (like 145 Mhz) and the scanner will "bounce" between the two, picking up anything in between.

Do you have the operating manual? If not, here is a copy

Turn on your Pro-2010 by rotating [VOLUME] clockwise. (When first turned on, your Pro-2010 may start scanning).
Rotate [SQUELCH] fully counterclockwise. You'll hear a rushing noise from the speaker. Slowly rotate [SQUELCH] clockwise until the noise just stops.
You're now ready to start entering frequencies.

Programming Frequencies
Before programming frequencies, make sure your Pro-2010 is turned on and the SQUELCH is adjusted.
Suppose you want to program Channel 1 to receive 162.55 MHz. Here's how you would do it:

1. Press [MANUAL] and select channel 1. You can do this in two ways:
press [MANUAL] continuously until the Display indicates Channel 1 or
by pressing [1] [MANUAL].

2. Press [PROGRAM] to enter the programming mode.

3. Enter the desired frequency. In this case, press the [1] [6] [2] [.]
[5] [5] keys. Check the display to make sure the frequency it shows
is the one you meant to program. If it is, press the [ENTER] key.

4. To add more frequencies, just press [PROGRAM] to advance to the next
channel and follow the steps above.

5. If you ever want to change the frequency entered for a specific
channel, just enter the new frequency "over" the old frequency using
steps 1, 2, and 3.

Make a mistake while entering the frequency? Just press [CLEAR], enter the correct frequency and press [ENTER]. If you're entering a new frequency in place of an old one, the old frequency won't be "erased" when you press [CLEAR]. It will remain stored on that channel until you correctly enter a
new frequency and press [ENTER].

You'll hear a "peep" sound as you press the various keys. This lets you know the key has been properly "entered" into your Pro-2010.

Using the Scanning Function
Your Pro-2010 will automatically scan all the channels you've programmed and stop whenever it finds a signal. To scan channels, just press the [SCAN] key.
To stop scanning, just press [MANUAL] and you can select specific channels
you want to listen to.

IMPORTANT! Your Pro-2010 won't scan unless SQUELCH is set to the point where no sound is heard if a signal isn't being received.

Delay Function
When your Pro-2010 is scanning, it will stop whenever it finds a signal on a channel. As soon as the signal ends, the scanning function will resume. Most communications heard will be two-way. To make sure you don't miss any replies, press [DELAY]. This will cause your Pro-2010 to stay on a channel for two seconds after the end of a transmission, giving you time to hear any reply. To release the Delay function, just press [DELAY] again. The Delay indicator will show on the display when the Delay function is used.

Lockout Function
You may want your Pro-2010 to "skip over" certain frequencies while it's scanning (such as continuously transmitted weather broadcasts). To "lock out" such channels, follow these steps:
1. Press [MANUAL] to stop scanning. Continue to press [MANUAL] to
advance to the channel you want to lock out.

2. When you reach the channel, press [LOCK OUT]. The display will show
[o] to indicate this channel will be skipped over during scanning.

3. To release the lockout, press [MANUAL] to stop scanning. Advance to
the channel that is locked out and press [LOCK OUT] once again. [o]
will disappear from the display.

If you use the lockout function on all channels, scanning will be impossible - you'll only be able to change channels using [MANUAL].

Speed Selection
Your Pro-2010 will normally scan channels at a rate of four channels per second. If you press [SPEED], channels will be scanned at a rate of nine per second. Press [SPEED] again to return to a rate of four channels per second.

Priority Function
You might want to scan other channels yet not miss a call on a channel of particular interest to you (police, fire, ambulance, etc.). The Priority function will let you scan other channels - but if a call is received on the Priority channel, your Pro-2010 will automatically switch to the
Priority channel!

1. Only Channel 1 can be used as Priority Channel: Key in the desired
Priority frequency into Channel 1.

2. Priority function works only when the unit is in Scan or Manual mode.

3. Press [PRIORITY] to start Priority function. A [P] will appear on the
display.

4. Press [MANUAL] or [SCAN] to listen to other channels. Your Pro-2020
will check the Priority channel and switch to it if a signal is
received on it.

5. To cancel Priority function, press [PRIORITY] again. the [P] will
disappear from the display.

SEARCHING WITH YOUR PRO-2010
One great feature of your Pro-2010 is its ability to "search" for frequencies being used. This means you can hear all the action on the airwaves in your area! To use this great feature, just follow these steps:
1. Press [PROGRAM] key.

2. Press [LIMIT] key. Enter the lower limit of frequency range to be
searched (such as 45.00 MHz). Press [ENTER].

3. Press [LIMIT] key again. Enter the upper limit of frequency range to
be searched (such as 46.00 MHz). Press [ENTER].

4. Press either [up arrow] or [down arrow] to start Search. [Down arrow]
will start search from the highest frequency and go down. [Up arrow]
will start from the lowest frequency and go up.

5. You can control the speed of the search by using the [SPEED] key to
accelerate or to slow down the search.

6. Search will stop when a frequency is found with a signal. To restart search, press [up arrow] or [down arrow]. In Program Mode, search range will be displayed each time [LIMIT] is pressed. It is impossible to change the lower frequency only: to change lower frequency you must change higher frequency first. The higher frequency can be changed any time.

Storing Frequencies
If you want to enter some of the frequencies found during search, do this:
1. Press [MONITOR] when your Pro-2010 finds a frequency you want to store.

2. Use [MANUAL] key to select a channel to enter the frequency your Pro-
2010 found. The display will show the frequency currently stored on
the channel, but don't worry - the old frequency will be erased when
you start to enter the new one.

3. Press [PROGRAM].

4. Press [MONITOR] again. The new frequency found during the search will
be displayed.

5. Press [ENTER] to put the new frequency into the channel in place of
the old frequency.

6. Press either [up arrow] or [down arrow] to resume the search. To
return to manual or program operation, press [MANUAL] or [PROGRAM].
To resume the search from one of the limit frequencies, press [LIMIT]
and then [up arrow] or [down arrow].

Error Indications
Sometimes when you try to enter a frequency for a channel or as a search range limit, you may find an ------ on the display. This means the frequency is in error and you won't be able to enter it into your Pro-2010. Such frequency errors usually mean you've entered a frequency outside the ranges your Pro-2010 operates on (such as 225.00 MHz) or you've put the decimal point in the wrong place (14.682 MHz instead of 146.82 MHz). Check carefully to find your mistake and then press [CLEAR]. You can now enter the correct frequency.

Hope this helps,

PROBLEM W/ CASIO fx-260 SOLAR


Sorry, but I think you misunderstood what the manual says. See the not on the screen capture.
True the sentence is not very clear, but what it means is the following:
All modes (except COMP) will have an indicator (with the appropriate labeling) displayed. When in COMP mode the COMP indicator is not displayed.

The truth of the matter is that computation- wise you have two MODES only : the general COMPutational mode and the Standard Deviation (SD Statistics) MODE. These two are incompatible because the key layout is different.

But to compute trig functions
  1. calculator must not be in SD mode, hence it is in COMP mode
  2. An angle unit must be shown on display.
Read the screen capture about the MODES of this calculators. DEG,RAD, and GRAD remind the user that the angle units in trigonometric function calculations and coordinate conversions are in degrees, radians or grads. They have nothing to do with the other calculations you are doing.

874c328.jpg

You can only remove DEG by changing the angle unit to RADians or GRADs. In so doing, the new unit indicator (RAD, GRAD) will be displayed instead. There is no point worrying about the angle unit indicator unless you are performing coordinate conversions or calculating trigonometric functions or the inverse trigonometric functions.

MODE 9 cancels the FIX display format: decimal are displayed with a fixed number of decimal places (set by the user). After this key sequence the decimal display format reverts to NORM(al).

Raidoshack 1000 channel scanner


The frequencies probably aren't the same, so you're gonna have to do a little research, but hope this helps.

  1. Turn the scanner off and then back on.
  2. The first thing we'll do is clear all of the frequencies in the bank you'll use to listen to Gwinnett County.
  3. Press the black F button, then press 0, then press the F button again, then press CL, and then press the 1 button.
  4. Enter 000 and then press PGM to enter programming mode starting at channel 0. On the display the P on the left of the first line of the display says you're in programming mode, and the 000 indicates your looking at channel 0.
  5. Press the orange T button to enter trunking mode.
  6. Press the MODE button until Motorola is displayed on line 2 of the display.
  7. Press the PGM button again to begin entering frequencies. You'll enter 24 frequencies total. If you make a mistake while entering a frequency you can press the CL button to delete the last number entered. If you accidently press the PGM button twice while entering frequencies you can press the down arrow to back-up to the previous location.
  8. Enter the first frequency, 854.78750, then press ENT and then press PGM to go to the next channel.
  9. Repeat step #8 for the rest of the frequencies 854.81250, 854.83750, 855.31250, 855.48750, 855.76250, 855.78750, 855.81250, 856.81250, 856.83750, 856.91250, 857.81250, 857.83750, 857.91250, 858.78750, 858.81250, 866.13750, 866.21250, 866.38750, 867.33750, 867.38750, 867.96250, 868.11250, 868.13750, 868.48750.
  10. To double-check that you entered all of the frequencies correctly enter 0 and then the PGM button to go back to the first frequency entered.
  11. Press PGM to go through all 24 frequencies, if you see a mistake enter the correct frequency and then press ENT to save it, continue pressing PGM until you have verified all 24 frequencies.
  12. Next press 0 and then PGM to go back to the first frequency again.
  13. Press the MODE button until you see MO following the channel number on the first line of the display (P000 for example). After MO is displayed press PGM to go to the next frequency.
  14. Repeat step #13 for each of the 24 frequencies.

Operator/instruction manual


ghilger, First off, has your radio been converted to open up all the other channels(including CB)?? That has to be done first, or it's locked in the ham freq's. I think the factory manual is pretty well detailed, but i've been around radios my whole life. The mode button does the changing from am/fm/usb/lsb.Here's from the manual;

MODE: Operating Mode. Press the MODE control to select the operating mode. The operating mode is indicated on the liquid crystal display: am, fm, usb, or lsb.
* See, there is 2 different functions for each button. One set of functions are by just pushing the buttons, the other set of functions are obtained by pushing the function button first. The function button is activated by pushing in on the clarifier knob.
*Here is for saving of freq's;

Memory Save. To save in memory a specific
frequency and operating mode, select the desired mode and rotate the FREQUENCY control to the desired frequency. Press the FUNC button, and then press the M.SAVE button. S will appear on the LCD next to the frequency. While S is displayed, immediately press any of the memory channel buttons (1 - 5). The mode and frequency is now saved into memory. If the S indicator disappears before you press the memory channel button,
the information will not be saved and the process
must be repeated.

M.LOAD: Memory(Recall). To recall, any of the saved memory channels press the M.LOAD
button. L will appear on the LCD for several seconds. While the letter is displayed press the desired memory channel button (1 - 5). The programmed mode and frequency will be displayed.,
If you have any more questions about the radio, repost them here and I'll try to walk you thru them. The radio is a very good ssb rig, especially set up with a power mic. Hope this helps,, Mechanic
