You apparently have unheard messages on the voicemail system provided by your telephone company. This system records messages when someone calls while you're already on the phone. Please contact your telephone company for instructions on accessing their voicemail system.

Put the non-registered handset in the master base unit. Unplug the base unit for about 10 seconds and plug it back in. Wait for a message to change on the handset and press and hold the handset locator button for 4 seconds. This will re-register the handset. Do not remove the handset from the base while performing the above steps. Good Luck!

That is the message waiting indicator, it is telling you that your Call Notes (Or whatever your service provider calls it's voicemail) has a message waiting. If you do not have a message waiting, you can turn the light of by following these steps:

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 and
appears in the handset display. 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.
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.
A beep sounds and the message alert tone is reset.

Another tip is to remove the battery from the handset for at least 5 seconds. You might want to get a voltage meter and check the voltage on that new battery - maybe it isn't charging properly.

reset your base unit by disconnecting power, then hold find hs button while reconnecting power.

I found the 800 number to call, spoke to customer service, they gave me the suggestion of unplugging the base from the outlet, removing the batteries from the handset, wait 5 minutes and plug in and put in the batteries. Yes, that fixed it. And then the customer service technician called back later to see if it had worked. I thought that was above and beyond the call of duty. Certainly a good way to win customers!

The red blinking light is an 'event' light, it does not necessarily mean a message is waiting for you, it will also start to flash if you have a missed call.
click 'up' on the round button to show the missed calls list and it will stop flashing, at least it does on mine!

Panasonic KX-TG1050N Cordless Phone. Base handset (No. 1, KX-TGA100N) does not work, no keypad response or dial tone. Green indicator message light ON (should only work with the TG1000N base unit) all the time till battery runs down. Display shows message ?C533?. Can still send and receive calls on extension phones 2 and 3.

You need to reset the main base unit. Unplug the power from the back of the base. While the power is disconnected, press and hold the delete key while reconnecting the power. Wait for a long beep tone. When the display shows 88 or P, press play button one time. If you have a phone without an answering machine, disconnect the power from the back of the base, press and hold find hs button while reconnecting power.
