Handsets give 3 beeps, no dialtone

Usually the dial tone Beep Beep Beep means that you have a voice mail. This is a service or feature that your phone company provides. Sometimes it just a matter of dialing your home number from your home phone and it will prompt you to listen to or erase your messages. If this is not the case, call your phone company and ask them about the feature.

Sounds like its either going offline maybe checking the outlet and the cord that plugs into the base. It may also be the battery needs replacing,it has been run down and charged again too many times.it may hold enough for a dial tone but not enuff to even ring,just beep I stead

Resetting the voice message waiting indicator
When you receive a new voice mail message, the new message LED on the top of the handset flashes. In the event your message waiting light gets out of sync with your phone company's
voice messaging system, you can manually reset it back to the "No messages waiting" state.
1. Press and hold FiND on the base for five seconds.
Note: The handsets connected to the base will start to beep, however, keep pressing for five seconds.
2. A beep sounds and the message alert tone is reset.
Changing the dial mode
Your phone can communicate with the telephone network in two different ways: tone dialing or pulse dialing. These days, most base networks use a method called tone dialing, so your phone comes programmed for tone dialing. If your phone company uses pulse dialing, you will need to change your phone's dial mode. If you don't get a dial tone or can't connect to the telephone network, please follow the steps below to modify your phone's settings:
1. Press MENU/SELECT.
2. Select the Global Setup menu, and then the Dial Mode submenu.
3. Scroll to highlight Pulse.
4. Press MENU/SELECT. You will hear a confirmation tone.
If you ever need to change the dial mode back to tone dialing, follow the same procedure, but select Tone in step 3.

Finally for future ease of use, here is a link to the user manual were I copied the above information from:

Cellular phones to not use tone dialing. If you hear a dialtone at anytime it is simulated by your phone company however their is no dialtone.

make sure the phone is plugged in. You'll need dialtone first, the other issue will fix themselves once you have dialtone!

You can download the instructions from GE here. In the meantime, try placing the handsets onto the main base unit for 20 seconds each. The instructions say this is how you register the extra handsets with the base.

Deregistered 4 handsets, on suggestion from FixYa, by pressing hangup & # sign.
Then reregistered to base.

I think I have the same phone. You have to put the handset with no dialtone in the main charger for about 30 seconds to reset it to the base.

One of the phone handsets of the Panasonic KX-TG563 trio gives me static w/ dial tone and then shuts down or it gives me the message that "System is busy/Line in use" with no dial tone. If I get closer to the base unit it seems to work but w/ alot of static. The base unit phone works good and the other handset works ok too. The battery shows fully charged however, when I take the battery out to try a reset when I put it back in the battery indicator show very low. I tried switching batteries w/ the othe hand sets it doesn't help.

Thanks

I have had the same problem before and now again for the last week...I finally remembered what I did last time to solve it!

I put my "unavailable" Handset into the main cradle and left it there for a slow count of 20. That has reset the unavailable handset and returned the dial tone etc.

Maddening isnt' it!
