NEC Dterm80 LCD display problems

This is a technical problem beyond the basic programming functions of the phone such as you would find in a user's manual. It requires support from a phone technician. For example: https://sundance-communications.com/forum/ubbthreads.php/topics/246760/dterm-80-caller-id-programming I don't think online advice will be of assistance. There is barely the possibility that Startech.com could be of service. Otherwise, your technician supporting your phone service will have to assist.

Ribbon cable inside phone to display sometimes gets jarred loose. If you can remove the base, then unscrew the 2 screws holding the display in place, then slide it out and look for the ribbon cable being loose. If you have small hands maybe you can get that back to its spot. Better yet buy a replacement phone on eBay for 25 bucks instead of hoping it'll go back in and work properly. Some displays go bad line by line, in which case there's no help for it.

The LCD screen of my DTerm80 was showing a "CAMP-ON" message along with someone else's name. I fixed it by pushing the "Exit" button then the second softbutton, under "Clbk", then the first softbutton, under "All". I received the message ""CLEAR CALLBACK CAMP CANCEL"

Fixed my problem.

That is a sign of bad LCD panel, not much you can do about it, it will get worst with more lines.

The keyset’s display provides a 3-line, 24 character per line alphanumeric
display that displays various information for the telephone
either while on a call or while idle. You can change the contrast of the
display as well as the language used when displaying the prompts.

You have to make sure the phone system you have has CID cards in it. What kind of card is in the Electra phone system.

This one could have different variables.

1. your CO lines must have CID
2. your CO card in the system must have CID capability
3. older systems have a limited number of extensions that can display CID (16)
4. your ext must be set to ring.
