Can't get numbers to display

I haven't used this in some time, so I replaced the battery and I cannot get the on/off button to work. It will only turn on when I press the AC key. When I do, no numbers will register on the display. It just stays as 0. What is not right here?

Make sure there is not a key stuck in the depressed state. If so try to pull it back up and you should be set. If the machine had a liquid spill this could cause that type of error too. In which case the machine is junk.

I have had my radio for many years but when I wanted to put it in another room it displays a half "L" on the display when I plug it in. Do I have to replace the battery when I'm using an...

Hello
You haven't specified nothing about your Emerson Smartset Clock Radio. Nothing is there about its model number. Yet I posts this solution before you assuming that yours' is a CKS3528 Emerson Clock radio.

There is a long life lithium battery installed in this clock radio when you buy it.

This battery can maintain the time and alarm settings for 3 to 5 years, or even

longer, so there is no need to pay for a new 9-volt battery every 6 months, as
is recommended in other clock radios with normal battery back up.
But if this lithium battery has gone down [ in terms of voltage]; the display 'L" will be there. It means that, it is time to replace this backup battery. It will be of disc type, usually used as bios setting storage, used in computers. OK.

Operating instructions for EM-2R power meter. it has 3 plug-in sender units with remote reader. How do I resynch the senders and reader after replacing battery in reader? Cheers DaveK

I have what appears to be the same device. My instructions list the following method:
1. turn off or disconnect all the remote monitors.

Use the code button on the display module to set the channel. It displays 1 --:-- for channel 1.

Plug in the first remote sensor into the power outlet and press and hold down the SET button until the LED flashes.

The receiver will show numbers where the dashes were in the display.

Change the channel on the receiver to 2 withb the code button, it displays 2 --:--.

Plug in the second remote sensor, press the set button till the LED flashes.

Repeat for channel 3 with the third remote sensor.

This is the same method used to set them up the first time. Having to turn off or unplug the device is the unintuative bit. I assumed it would reconnect after replacing the batteries.

Hi. I have a Casio CE-3700 that is only used for a few weeks of the year. Once I month I try to turn on the machine and leave it powered up for around a day. I am now wanting to actually use the machine....

It sounds like the machine has lost some programming. What you were doing once per month is what I recommend if not used regularly, but the battery has probably now got to the stage where it is too old to even hold charge for a month. It is probably best to get the battery (internal vanadium type) replaced as it may have started leaking if it is too old. The dealer who replaces it can reset your decimal places at the same time. If you just want to get it running as is and take a chance, then do the flag clear (to get the FFFFFFFFFF on display then SUBTOTAL) on one of your WORKING machines, and tell me the big number that it prints out (this will not lose any data on your working machines, it just reads the settings)

How do i reset my yamaha dx 100 back to original factory settings

yamaha dx100 reset. Press voice switches 1 and 2 while turning power switch on. Display will say test entry?. press the plus/yes button. This will reinitialize all memory to factory settings. Also the lithium ram backup battery voltage will be displayed as check level with a number representing the battery voltage. The number will be 10 times the actual battery voltage. A new battery will display 33 representing 3.3 volts. If your reading is below 22 then your battery is shot and will need replacing and if you turn the unit off it will probably get a scrambled memory again.

The calculator is intermittent: Most of the time

Not knowing what to do, I tried anything that could possibly help:

I installed fresh batteries and I pushed the reset button on the back of the calculator (Sharp EL-546L) and finally, it work all right after more than 5 years I own the calculator and where it did work correctly for 5 minutes. I tried the reset button in the past (long time ago) and it didn't work. This time it worked because, maybe, I've used fresh batteries.

Radio stuck in safe mode

Turn on radio - the word SAFE will appear in the display. Press th P.SCAN and RBDS buttons simultaneously and hold them down until "1000" lights up in the display.Release buttons.Do not, under no circumtances, continue holding them down or press them once again. This will cause the radio to consider the number 1000 to be the input code.Use station buttons 1,2,3,and 4 to enter the code number on your Radio Card. Use the button 1 to enter the first number 2 for the second number 3 for the third number and 4 for the last number.Once you have entered the code and it shows on the display,press the P.SCAN and RBDS buttons down again simultaneously and hold them down until the word SAFE appears in the display.Release buttons. Soon afterwards a frequency will be displayed.

ADX5355 clock

you just have to turn the power on, push the display button so the time is showing on the display. (The only buttons involved are the "BAND" button, the number 4 roulette button which is the top right station preset button and the "DISPLAY" button.) I think you push and hold the BAND button and while holding it push the number 4 roulette button. (you don't have to hold it for any specific time you just have to push BAND in when you push the number 4 roulette button.) the time will flash and you use the vol/seek knob to adjust the time. When done push the BAND button again.
=> This really work, thanks!
