Question about Kenwood PB-34M, ,TH-22AT,TH-42AT,TH-79A, 9.6v 1000mAh NiMh Pk 2-Way Radio

1 Answer

My TH79A keypad does not respond to any commands even with the Key Lock turned off. The only thing I can change is the frequency via the ENC control. The radio is stuck on VHF and EL power only. I can receive on VHF by selecting the required frequency on the ENC control, but I can't transmit using the PTT button. Not even the backlight comes on when I press the lamp button. "VFO reset?" appears when I do a [VFO] + POWER ON, but pressing [VFO] does nothing. I've also tried [F] + POWER ON, which just performs an LCD test with all segments on and both transmit LED's showing yellow. It locks up in this mode until I switch off again.

    Receiver comes alive on vfo stations and also some repeater channels. A total reset was performed and all information was reloaded from computer via data cable. Problem is still there.

Hi.

It looks like the key panel is defective and must be replaced. Standing to your description the receiver is working. Here the biggest third party part seller. Call them and find out if the panel listed in parts includes the key pad.

Kenwood has no parts for old model. If Partstore does not have the spare, try Kenwood, or look for second hand parts on Ebay.

Regards.

Ginko.

Numerical keypad offset numlock on keyboard


Examine your keyboard to ensure your "Number Lock" key is not activated.

This activation is indicated by the key being lit up.


If the key is activated, press it to deactivate the lock.

The number lock key will deactivate an entire segment of your keyboard


Start, click Run, and type regedit to open the Windows registry editor.

In the registry, open the below folders.

HKEY_CURRENT_USER\
Control Panel\
Keyboard\

Within the keyboard folder, you should have a string value named "InitialKeyboardIndicators" with a value of 0, 1, or 2. Below is the explanation of each of these values.

0 = Num Lock is turned OFF after the logon.
1 = Disable Num Lock.
2 = Numlock is turned ON after the logon.



hope this helps

How to lock or unlock a Samsung Intensity


Many people like the Samsung Intensity because of its slide-out QWERTY keyboard. However, one drawback to the phone for some users is that, unlike a flip phone, the numeric keypad is always exposed. When the Intensity is kept in a pocket or purse, this can result in accidental phone calls, multiple all-black pictures, and sudden activation of the voice command feature.

Luckily, you can lock the phone's keypad to keep it from engaging any functions when you're not using it. Locking the keypad is easy. Just hold down the 0 (zero) button for about two seconds, and a message will pop up telling you that the keypad has been locked. While it's locked, you won't be able to use the numeric keypad.

The standard way to unlock the phone is to press the upper right options button (the one that you would typically press to bring up your Contacts list) and then press the center OK button. (You will see prompts for both of these buttons when the phone is locked.)

However, there is also a quicker way to unlock the phone -- just slide the keyboard open. Sliding the keyboard open will unlock your numeric keypad immediately, and even when you close the keyboard the phone will remain unlocked. If you want to lock it again, you'll have to hold down the zero button to re-lock it.

You can also enable Auto Key Lock mode, in case you think you'll forget to lock your phone. With Auto Key Lock mode turned on, your phone will automatically lock itself when it's not in use and the backlight goes off. You can turn Auto Key Lock mode on or off from the Phone Settings menu.

• To scan memory channels, press SCAN. To hold a channel, press MANUAL.

I saw your response to a question about the Toshiba 32A33 TV ...


Definitely, there is some keypad failure. There is a continuous contact anyone of the key. Since key is contiunuosly giving command to the processor Remote function is automatically cutoff. My simle Tips to find out key failure. Good key give "Tick" sound when you press the key softly. The sound is very very low, you have to observe carefully. Otherwise blindly change all the front panel key. Cost is very very low. When the keypad problem is solved, remote will function automatically.

Stuck on scan mode


Hi, It sounds to me like your keypad is locked. Pg 63 of your manual.
***using the keylock ***
Once you program your scanner, you can protect it from accidental program changes by turning on the key lock feature. When the keypad is locked, the only controls that operate are FUNC, key , SQ, and VOL. You cannot activate the keylock while you are entering a frequency into a channel. To turn on the keylock, press FUNC then key . Key locked appears for about 1 second. Key locked appears when you press any key after locking the keypad.
To turn off the keylock, press FUNC then key . The scanner beeps three times and Key unlocked appears.
The only other choice I see if that does not work would be to initialize it. Pg 84 of your manual. Hope this helps you,, Mechanic

LG LMVM2055SB over the range microwave keys not working


Is it possible someone may have sprayed cleaner directly onto the keypad area?

This causes moisture to get into the keypad and sometimes onto the control board.

This could mean that they control panel frame with keypad (membrane switch) would need to be replaced.

Can you give more details on the cleaning?
