How to program the radio in a 96Lincoln continental after battery was disconnected


Hi,

Here is the link to the owners manual which you can download if you wish:

http://owner.ford.com/servlet/ContentServer?pagename=Owner/Page/OwnerGuidePage&year=1996&make=Lincoln&model=Continental

Here/below are the specific instructions on the radio programming (pg. 159 of above link).


Good luck & please flag if "HELPFUL". Thanks!

(from section) Luxury Audio System


Selecting the AM or FM frequency band

Push the "AM" or "FM1/FM2" button to select the desired frequency band. Pushing the "FM1/FM2" button more than once will alternate between FM1 and FM2. These functions are used with the station memory buttons described under How to tune radio stations.

HOW to tune radio stations

There are four ways for you to tune in a particular station. You can use the "TUNE", "SEEK", 'SCAN"or memory buttons.

• Using the "TUNE" function:
You can change the frequency up or down one increment at a time by Pressing and releasing either the left (< arrow/up) or - right (> arrow/down) side of the "TUNE" or "TUNE DISCS" button. To change frequencies quickly, press and hold down either the right or left side of the button.

Manual tuning adjusts your radio to any allowable broadcast frequency, whether or not a station is present on that frequency. (See All About Radio Frequencies in this section.)

• Using the "SEEK" function
: Press the right *) side of the "SEEK" button to select the next listenable station up the frequency band. Press the left (.4) side of the button to select the next listenable station down the frequency band. By holding the button down, listenable stations can be passed over to reach the desired station. Pressing the "SCAN" button will begin the scan mode up the frequency band, stopping on each listenable station for approximately five seconds. To stop the scan mode on the presently sampled station, press the "SCAN" button again.

Setting the station MEMORY PRESET buttons
: Your radio is equipped with 6 station memory buttons. These buttons can be used to select up to 6 preset AM stations and 12 FM stations (6 in FMI and 6 in FM2)

1. Select a band, then select a frequency.

2. Press one of the memory buttons and hold until the sound returns and the lamp above the memory button lights up. That
memory button is now set.

3. Follow the above steps for each memory preset button.

NOTE:
Custom memory presets can be recalled using the keyless entry system. See Memory Profile System in the Features chapter.

Using the Automatic Memory Store feature ("AUTOSET")
: If the memory buttons have been set, either by using the Auto Memory Load feature or if you have set them manually, the system is prepared tolet you use a convenient feature called Automatic Memory Store.

With Auto Memory Store, you can continually set strong stations into your memory buttons without losing your originally set stations. Your radio will automatically set your memory buttons to the strong local stations.

Activate Auto Memory Store by pushing the "AUTOSET" button once. Your radio will set the first six strong stations of the band you are in (AM, FMI or FM2) into the memory buttons. The display will flash "AUTO" and display the autoset icon "A" while the stations are being set in the memory buttons.

NOTE: If there are less than six strong stations in the frequency band, the remaining unfilled buttons will store the last strong station detected on the band. After all stations have been filled, the radio will begin playing the station stored on memory button 1.

To deactivate the Auto Memory Store mode and return to the manually-set memory button stations, simply push the "AUTOSET" button. Display will show "AUTO" then "OFF". The next time Auto Memory Store is activated on that band, the radio will store the next set of six strong stations.

I have 4 motorola walkie talkies the channel numbers on one do not match the other three when they are on the same frequency how do i reset the one that is wrong


If they're not exactly the same model they may have different channel indexes. If the "oddball" is a combination FRS/GMRS or if the other 3 are, they'll have different numbering. As long as you can talk between all of them, just make note of the "right" numbers when they're working.

Cp9430r


Fixed Hunter ceiling fan with remote light pin out wiring 9 wire plug search words
Hunter Ceiling Fan with remote, fails to turn on light, fails to turn on fan..remote receiver is Cp9430r
1) Test your remote, Hunter uses Radio Frequency remote, point RF remote one inch from antenna of working AM radio, press each button on remote, each button will produce static sound from AM radio, if no sound..check battery wiring or solder connection on loop antenna of remote. If no sound on one or more buttons, disassemble and wash key pad with dish soap, rinse and fan dry, retest. If still one button no work apply graphite paint to button to rebuild conductivity of button.
2) Cp9430r receiver is below fan and above light. Remove light assembly, check receiver dip switches, mine was #5 On 1~4 Off, check remote control dip switches in 9v battery compartment also set #5 On 1~4 Off, new 9v battery still no Fan reversal "click" sound heard coming from the large Blue fan reversal relay located inside the Cp9430 receiver. All other buttons control transistors and will make no sound even if they are working.
3) Disassemble / unplug 9 wire plug from Cp9430r receiver, place receiver on wooden table, 9 wire plug has two empty pin squares, one empty in the center, the other empty we will call #1 ..counting clockwise #2,#3...#4,#5..#6,#7and finally top center next to empty #1 is #8. Now #8 is 110v hot/black ...& #4 neutral/white.
4) Shock Danger..carefully apply ac volts to pins #8,#4 use tape if needed, locate quad operational amplifier i call it radio receiver chip HA17324 on board, google HA17324 Datasheet, locate leg #14 it is across from leg #1. Locate small yellow ceramic capacitor very near leg #14, use capacitor's neg as neg for voltmeter, test volts at #1,#7,#8 and #14. My #1 was 3.1v, #7 3.2v, #8 3.25v and #14 .01v ...why #14 so low? I monitored each leg while pressing remote control buttons...no changes. **Desperate, I sparked (1/2 second or less) #14 with 3.14v from positive leg of yellow capacitor** and retested all legs, no change except now #14 rests at .02v and jumps to 2.5v~2.8v when any button on the remote is pressed then rests at .02v. Now Lights work, Fan speeds work, Reverse rotation Works :-)
Pin Out on 9 wire plug, #1 Empty pin, #2 Alternates w up/down fan rotation, #3 goes to 5uf fan capacitor other side of cap goes to white/neutral AC Line, #4 AC Line neutral, #5 goes to Triac? speeds? , #6 Alternates up/down fan rotation goes to up/dn blue relay, #7 goes to up/dn blue relay looks to be AC hot looking for fan probably paired with #3 changing sides at up/dn blue relay, #8 AC Line hot in. Why did **sparking** work, smarter people might know, i think a small spark got stuck in the chip and sparking helped the chip release it out. No electrical education, novice. Jer. 51 8,9 and 11

Kenwwod DPX303 dead, Worked yesterday and today wont power on. Fuses are all OK . Hit the reset button no change. Any Ideas? Rgds R


There may be multiple fuse boxs in your car, you need to make sure to check all of them listed in your owners manual. Checking involves a voltmeter and not just checking the 2 fuses you think supply power to the radio, there may be multiple fuses that supply the necessary power to the radio. Yellow and red at Kenwood need to see 12 volt positive with the key on and the black needs to have ground in order to turn on. If all three have correct voltage then pull the harness from kenwood and check small 10 (red) or 15 (blue) fuse held in and protected by the harness. Good luck!

I get all channels locked out. How do I unlock the channels.


You are pressing the "scan" button in the upper left hand position and getting all channels locked out? Correct?
If you haven't programmed any frequencies the channels will stay locked out. Get your local frequencies by doing a search for police scanner frequencies. Once you have gotten the information for your area press the "PGM" button on the lower right hand side of the key pad. Input your 1st frequency ###.#### then press "ENTER". Press "PGM"key again and enter your 2nd frequency then "ENTER" again. Repeat as often as you wish to enter more frequencies.
When you are done, (you can stop any time) press the "SCAN" button in the upper left hand position and you are in business. You are supposed to be able to choose which memory position you wish to use but I haven't tried to figure that one out.
If you need the manual for the radio go to radioshack site and do a search for PRO95 and it will come up in PDF format.
Hope this helps. I have owned the pro 95 for maybe 6 or 7 years and after doing a little programming yesterday the thing is much more to my liking. It scanns quicker and scans the channels I wish to listen to.

Make sure you are entering your frequencies in empty channels unless you want to over write one that you don't want to use any longer. Press "PGM" until you get to an empty channel.

Unlocking channels


first press the manual button so you can go through the channels one by one. Then look for a button that has L/O(lock out) push this once for every channel you have a frequency programmed for it, the channel will probably not unlock if there is no frequecy programmed to it.

per roupe50 above
