Batteries failing I have a Panasonic KX-TG9344T system - base unit plus 6 satellite phones. - base + 4 units 7 yrs. old - spare base + 4 units - 3 years old; using 2, 2 spare In the last month, batteries are dying fast. Can I replace them? Can I check voltage at the phone terminals?

Found out how to change the handset number [1] [2] [3] [4] etc on a Panasonic Cordless handset

Panasonic KXTG6644B

Changing Handset Number:
Deregister two Handsets [#1 & #2] 0r [#3 & #4] etc

On each handset hit -
[MENU] # 1 3 1
[ERASE] [YES]

(This leaves and open space on the base unit)

Re-Register 1st Handset [#1]
[MENU] # 1 3 0
Hold [LOCATION] on Base Unit 5 Seconds
Place the Handset you want #1 in Base Unit

Re-Register 2nd Handset [#2]
[MENU] # 1 3 0
Hold [LOCATION] on Base Unit 5 Seconds
Place the Handset you want #2 in Base Unit

Please refer page 31 in the attached manual for registering handsets to base unit. Good luck.

335 is the magic code when you want to remove a previous handset or base station registration!
Handset:

1 " (middle soft key) i L i #

2 Enter "335".

3 "Cancel Handset" i #

LThe numbers of all handsets

registered to the base unit are

displayed.

4 Select the handset(s) you want to

cancel, by pressing the desired handset

number. i #
5 "Yes" i # i {ih}
Base Station:

A handset can be registered to a maximum

of 4 base units. A handset can cancel a base

unit that it is registered to. This allows the

handset to "forget" the base unit.

1 " (middle soft key) i N i #

2 "Registration" i #

3 Enter "335".

4 "Cancel Base" i #

5 Select the base unit(s) you want to

cancel, by pressing the desired base unit

number. i #
6 "Yes" i # i {ih}

Remove then replace the batteries from the hand set. You should now get dial tojo.

I called you 800 number in the day to talk to a real person, and they told me what to do. - much better than your confusing web site. Thanks!

I plugged in my telephone which my 3 year old grandchild had unplugged!!
Thank you so much!!

I've just got a 2nd system of 3 handsets (KX-TG1033, DECT 6.0). I have also the same sytem in my house. Is it possible to expand 3 new hansets (number 4,5 and 6) to my existing base unit?

(Got this from a Panasonic Support Tech...Thanks Panasonic!) The following steps are worth a try.... Resetting Handsets & Base Unit: 1) Unplug AC adaptor from base unit for 30 seconds. 2) Reset handsets by removing/reinstalling all batteries.
Re-register each handset to the base unit by following the steps below:

1. Press MENU, #, 1, 3, 0 on the handset. 2. On the base unit, press and hold the LOCATOR button for 4 seconds until the registration tone sounds. 3. On the handset, press the soft key below OK and then wait until a long beep sounds. 4. Press the OFF button to exit. Situate the base unit in a different location. Change the line mode from A to B or vice-versa by following the steps below:

1. Press MENU on the handset. 2. Press #, 1, 2, 2. 3. Press the up or down arrow key to select the desired setting. 4. Press the soft key below SAVE. 5. Press the OFF button to exit. If the problems persist, your unit is malfunctioning and is in need of repair or replacement.
