Please retain your receipt as your proof of purchase.
If the phone does not work at all, check these items first:
• Make sure the power cord is plugged into the base and an electrical
outlet not controlled by a wall switch.
• Make sure the telephone line cord is plugged firmly into the base unit
and the telephone jack.
• If the phone does not beep, or beeps four times when you press
P, the battery pack might need recharging or replacement.
• If the battery does not charge after six hours, replace it with
Replacement Battery 3500 (SKU# 90817).
• Make sure the battery pack is installed correctly.
If the above suggestions do not solve the problem, try re-initializing the
handset and base (see “To re-initialize the handset and base” below).
If you have no dial tone:
Check all the previous suggestions. If you still do not hear a dial tone,
disconnect the phone and try another phone in the same jack. If there is
no dial tone on that phone either, the problem is probably in your wiring
or local service.
If you hear a two-beep signal when you try to use the handset:
• The handset and base are not communicating properly. You might be
out of range. Move closer to the base and try again.
• If moving closer to the base does not help, follow the directions below
to re-initialize the handset and base.
To re-initialize the handset and base:
1 Disconnect the power to the base.
2 Remove the handset battery pack.
3 Wait at least 15 seconds.
4 Insert the handset battery pack.
5 Connect the power to the base.
6 Put the handset in the base to re-initialize.
