Try opening the phone battery compartment on the back of the phone, disconnecting the battery wire, then reconnecting the battery wire. Solved my "Out of Range" problem - phone came back on and worked properly.

After you play your messages, press the button on the left side of the on/off button...the one above the charge light. It looks like a circle with a line through it???
My maching isn't working right now or I would be able tell you exactly what the voice sais, but it is something to the effect of "to delete messages, press delete again." Just press that button again and it should delete everything.
Hope it works for all of you!!

If you tried the registration process discribed in the book, it is possible that the base may have gotten zapped. Happened to me. Bought a new DCT 758 (cheap at Amazon.com) with only one extra handset and used two of the old handsets with it. It will only support the handset in the base and 3 others, so you can't use all of the old ones (save them for extras).

if they are less than a year old you should be able to bring them back under warranty and get them replaced. sounds like they might have got a power spike and it killed the base.

Something may have failed in the base unit but there could be a telco problem that is cutting off service. If you can substitute a different phone and still don't get a dial tone, contact your telco to find out why.

Clear the Handset's Base Data
  1. To remove the base data from a handset when out of range of the base, press and hold the 'end' button and the '#' button simultaneously until the phone beeps.
  2. It will now be de-registered from the base.
Note: This requires that the base and handset can communicate with each other.

Clear the Base Handset Data

  4. The charge light will now flash.
  5. Sit any handset in the cradle.

Call the phone provider you are using, (verizon, att, etc.) they can help you to reset the password.

Hello Lynn:

Make sure the power cord is securely plugged into the telephone base. Plug the telephone base into a different working electrical outlet not controlled by a wall switch. Move the handset closer to the telephone base. It may be out of range. Reset the telephone base by unplugging the electrical power to the base. Wait for 15 seconds and plug it back in again. Allow up to one minute for the cordless handset and the telephone base to synchronize. Other electronic products such as HAM radios and other DECT phones can cause interference with your cordless phone. Try installing your phone as far away as possible from these types of electronic devices.
