Handset display says "Connecting" I can't deregister. How can I get the handset to display "not registered"?


The procedures to deregister are, of course, specific
to each make and model number of cordless phone.
All of them are a LOT more involved than simply
removing the battery.

For some AT&T, VTech, Uniden, & GE model numbers
you might try the following:
=====================================
For many AT&T models it is simple:
1. When the handset says "Connecting..."
enter *331734 [menu]
it will soon (chirp) and display "Not registered"
=====================================
For many VTech models it is a bit more involved:
1. Start by taking off the battery compartment cover.
2. press [menu]
3. scroll up/down to "Settings"
4. enter * 7 8 9 0 #
5. if display reads "Test Base",
scroll to "Test Handset", press [select]
scroll to "next page", press [select]
6. scroll to "Register Clear?", press [select]
7. display asks "Confirm?" or "Register Clear??",
press [select]
8. display reads "Ok" (chirps), press [ off ]

9. UNPLUG THE HANDSET BATTERY
(this is why the cover is off)
10. Wait ~30 seconds, re-connect the battery &
replace the cover
11. display reads "Not Registered"
=====================================
For many Uniden models:
1. Press and hold the [END] and [ # ] keys at the
same time, after a few seconds the display reads
2. "System Reset, Deregister Handset"
3. scroll to "... Base Unavailable"
press [SELECT]
4. Handset (chirps)
press [END]
5. display reads "Not Registered, Place in base..." =====================================
For some GE models:
1. press "program[mute]"
2. scroll to "Handset Setup" press "program[mute]"
3. scroll to "Deregistration" press "program[mute]"
4. scroll to "Yes" press "program[mute]"
5. display reads "Not Registered"

=====================================
Once you have the handset displaying "Not Registered"
you can follow the User's Manual instructions to register
the handset.

The model number for your cordless phone is shown on
a small sticker underneath the battery in the handset --
enter this number at www.manualslib.com to get a free
copy of the User's Manual if you need it.

Good luck!

Unread messages


Have you configured your E-mail program to "show only the UNREAD messages", i.e., to "hide" all the messages that you have read?

  2. Enter a two-digit code from 71 to 94.
  3. Specify the external line by pressing a line button, a line pool button, or the intercom button. If you don't specify the external line, the system automatically chooses a line for the call.
  4. Dial the telephone number you want to program (up to 24 digits).
  5. Press [Hold].
  6. Record the code and number you have just programmed.
Hope this helps.

File or directory corrupted and unreadable


The directory is like a "table of contents" in a printed textbook.

If a child's crayons have been used to overwrite those pages, making them unreadable, then the table of contents cannot be used to locate the starting page-number of a specific chapter. So, one must read through the whole textbook, page-by-page, looking & trying to recognize the start of a chapter, and then the end of the chapter.

Similarly, there exist "file-recovery" computer software programs that do such "linear" reading of the entire ZIP disk, and trying to reconstruct the "file-structure" that was recorded in the "disk-directory".

Search for "file scavenger" software, and give it a try.
