Panasonic handset, KX-TG5632 buttons won't work

to turn off night mode http://www.manualslib.com/manual/793900/Panasonic-Kx-Tg1061c.html?page=25
do not think night mode would cause your problem.
check dialing mode #120
TONE ?
When you unplugged the base unit did you pull out the ac adapter for about 30 seconds to reset the base unit ?

The instructions worked after the additional KX-TGA402N handset was fully charged and I kept pressing the menu/ok button of the additional handset to advance from initial settings to the handset registration mode.


How do register an optional accessory handset to my existing main base...

1 Handset: {MENU} i {0}{0} 2 Base unit: Press and hold {LOCATOR/ INTERCOM} until the CHARGE indicator flashes. L After the CHARGE indicator starts flashing, the rest of the procedure must be completed within 1 minute. 3 Handset: Press {OK}, then wait until the handset beeps.

Follow these steps to register new handset.

1. On your Handset: Press Menu -> [0] [0] (menu then zero zero)
2. On your Base:
- Press and hold [Locator/Intercom] until the CHARGE indicator flashes.
The following must be completed within a minute.
3. On your Handset:
- Press [OK], then wait until the handset beeps.

That's it.

Hope this helps.

try unpluggjng base unit from power supply and then let handset unit reset to relocate the base unit.

place all handsets in the base unit for about 1 minute each. This links the handsets to the base. Sometimes the handsets lose their link to the base unit. If this doesn't work try to call Panasonic tech support for further information, the phones could be defective as well.

Well, I found the solution. I traded batteries from one the working handset to the non-working one, and the problem was corrected. Thus I need a new battery.

This works on MY panasonic; May work on yours too!

Registering a handset
The included handset and base unit are
preregistered. If for some reason the
handset is not registered to the base
unit, register the handset.
1 Handset:
{MENU} i {0}{0}{1}
2 Base unit:
Press and hold {LOCATOR/
INTERCOM} until the IN USE
indicator flashes.
LAfter the IN USE indicator starts
flashing, the rest of the procedure
must be completed within 1
minute.
3 Handset:
Press {OK}, then wait until a beep
sounds.
4 {OFF}
Registering an additional handset
See page 5 for information on the
available model.
Start from step 2.

I ordered a new kx-tg560m handset for my kx-tg5632 base unit, but the enclosed instructions for registering it with the base unit were wrong. Fortunately, I found the old quick setup guide in my files.

If you do not have the same base unit and handset, go to the URL:
http://www.panaxonic.com/RegisterYourHandset.

1. On the handset, press [MENU], then press [0][0]. The handset displays "Refer to manual to prepare base. Then press OK->"
2. On the base unit, press [SELECT] until the desired extension number [H1, H2, H3, or H4] is displayed on the base unit, then press and hold [CALL] until the CHARGE indicator flashes.
3. On the handset, press the [OK] softkey.

When the handset is off and sitting in the charger, the handset's extension is displayed in the upper right corner.

You will need to press the page/locator button and hold it down until the charge light flashes. Once you do this, go to the handset and push OK. It should register as handset 4. Hope that helps. CG
