20 Most Recent Panasonic KX-TGA600B Cordless Expansion Handset Questions & Answers

I have a Panasonic KX-TG6700 base unit and KX-TGA670B handsets. We had a similar problem where we were no longer able to deregister the handset using the handset itself. We wanted to be able to use that slot that the broken phone was still occupyng. The solution that we found in the manual online was to hold down the intercom button for 3 seconds until the "in use" light turned on. Then press and hold the number of the extension you want to deregister until it beeps. At this point the base unit has freed that extension.

The KX-TGA600 isn't an answering machine. If you have a separate answering machine connected to your phone line, please consult its documentation. If you're subscribed to a voicemail system provided by your telephone company, please contact your telephone company for instructions on accessing their voicemail system.

Try using the procedure below to reset the phone:

  • Disconnect all power adapter cables from wall sockets.
  • Remove all handsets from cradles.
  • Remove all battery from cradles.
  • Fit back the batteries in their handsets.
  • Place the new handset in the cradle.
  • Connect power cables.
The procedure above is supposed to reset the system and will re-sync handset to cradle.

If that does not work, then the phone is defective.In that case you will need to ring the customer support number listed on phone's instructions.

Some Panasonic cordless phones come with up to five handsets each will need to be properly adjusted. You may need to set the main handset to synchronize with the base unit plugged into the telephone wall jack and assign special configuration numbers to the other handsets in order to properly identify each one within a specified location. One handset left in the turned on mode may make it impossible to place calls with the any of the other handsets. This will continue until either the battery dies or fails on the handset or the phone is switched off and replaced in its charger for charging again. Synchronize the main handset by pressing the MENU button on the handset, then pressing the down button IN order to select the number you wish to assign to that handset. Repeating this process if you have already done so will greatly decrease the level of errors experienced with panasonic phones MORE USEFUL INFORMATION FOR ALL YOUR ELECTRONICS When troubleshooting these units, there are always several variables to consider. First check to see what last occurred with the unit such as did the children play video games, did the electricity go out due to bad weather. You may see that there are many possibilities but let's focus on what occurred last to the unit. Once we determine what happened last, we may isolate the actual cause of the problem. The actual cause may be associated with projection issues, older versions (Picture tube), interference from devices located nearby, and even a radio turned on and located really close to your unit. This is normally known as electromagnetic interference to electronics and is very common with the error you have provided today. Please continue to look for anything EXTERNAL to the unit before looking at the internal components. I have been working on these a long time so feel free to follow up with me.

Unlike a cellphone, your cordless phone does not have the ability to download ringtones. You have to select from the ones built in to the phone.

I think you may have had a power surge to do serious damage to your system.

I think it came in through the phone line. Your diverter is what got damaged....

You need a phone line surge suppression device.

You may have a bad base. Do you have other handsets that are running okay on your base? Are you confident your going through the registration procedures correctly with the replacement handset? Did you have a storm come through preceeding your problems?
