I need wall base unit for ge spacemarker 26976 corldless phone price please

Line in use means another phone is being used. If you have more than one phone, the second phone is off the hook or someone is already using the phone. Check all phones and be sure they are hung up.

Possible that the element has failed, has lost a connection from the control panel or there is failure in the control panel relay to the element.

Does it have a battery backup? If so, after disconnecting the AC power adapter, remove the battery for 15 minutes, then re-insert it (make sure it is a good battery), plug the AC adapter back in, and try again. Hopefully, this will re-set it. If not, it probably isn't worth tryiing to repair. May have to buy a new phone.

Here is a link to download the manual in pdf format.

Unplugged wall unit from the 110 volt outlet and the phone line from the unit for about 10 or more minutes. The phone worked after the phone line was reconnected and the wall unit plugged back in.

Dont know which solved the problem but I suspect it might have been unpluging from the 110 which could have reset the wall unit.

You should be able to get an RJ-45 coupler for the cord. It may be a little awkward but should work. Try:

Radio Shack
Frys Electronics
Menards
Best Buy
Your local hardware store

It is a tab on the base that the receiver "hooks" onto. You should be able to push it up twoard the top of the phone.

Handset can not link.
• If any handsets become inoperable, place it on the main base cradle for 20 seconds to re-register.
No dial tone
• Check or repeat installation steps
• Make sure the base power cord is connected to a working electrical outlet.
• Make sure the telephone line cord is connected to the base unit and the modular phone jack?
• Disconnect the base from the wall phone jack and connect another phone to the same jack. If there is no dial tone on the second phone, the problem might be your wiring or local service.
• The handset might be out of range of the base. Move closer to the base.
• Make sure the battery is properly charged (for 16 hours).
• Ensure the battery pack is installed correctly.
• Did the handset beep when you pressed the TALK/CALL BACK button? Did the in use indicator come on? The battery may need to be charged.
