I would recommend you perform a factory restore first. to do this, follow these steps;
Factory Default
This feature allows you to restore the handset’s original
features.
1. Press the FLASH/CALL WAIT/PROGRAM button until DEFAULT
shows in the display.
2. Use the CID/VOL (< or > )button to scroll to YES.
The default setting is NO.
3. Press FLASH/CALL WAIT/PROGRAM to confirm. You will hear a
confirmation tone.

Just of the wall, do you have a wireless mouse and keyboard in the house? Some manufactures of these devices use the same or very close frequency, this may have caused the unregister or your phone to the base. Unhook any other wireless devices in the house, remove the batteries from the phone and the handset, unhook the phone wire from the wall, disconect the power to the phone base and restart all as new, see if that will re-register your handset to the base.
There are some internal damages on the phone board. Could be some chip lines have gone bad.
Please consult a service center in your location for repairs and I bet it won't cost much.
Take good care it's a nice product you've got.
Thanks for using Fixya and remember to rate this suggestion.
cheers.
Has the handset become de-registered from the base?

Usually answered in minutes!
I can find nothing in the owner's instructions about that.
How do I go about re-registering the handset?
It was suggested that my handset was de-registered from the base. I WILL take it for repairs if RE-registering the handset doesn't work.
How do I register the set with the base?
Jim…
I do have a wireless keyboard and mouse. Removed the batteries from them and disconnected two wireless phones in living room, and EUREKA! the handset is now working. If It should happen again then I will do a process of elimination until I find the electronic device(s) creating the problem.
I however don't know how I could prevent this from happening again. Or is this a rare occurrence?
I do thank you for your assistance.
