If the phone doesn’t work at all, check these 
items first:
• Make sure the AC adapter is plugged into an outlet not 
controlled by a wall switch.
• Make sure the telephone line cord is plugged firmly into 
the base unit and the modular jack.
• Make sure the base antenna is fully upright.
• If the handset does not beep when you press P,the 
battery might need charging.
• Make sure the batter y pack is installed cor rectly.
• If you have dial pulse (rotary) ser vice on your phone 
line,make sure the dial mode is set to dial pulse (see 
INSTALLATION).
If the above suggestions don’t solve the problem, try 
re-initializing the handset and base:
1 Disconnect the power to the base. 
2 Remove the handset battery pack. 
3 Wait a few minutes. 
4 Connect the power to the base. 
5 Insert the handset battery pack. 
6 Put the handset in the base to re-initialize.
If you hear a two-beep signal when you try to use 
the handset:
• You might be out of range. Move closer to the base and 
try again.
• If moving closer to the base doesn’t help,try following the 
directions above for re-initializing the handset and base.
• The handset battery charge may have become low. Try 
charging the handset battery.
If the phone does not ring when you receive a call:
• Make sure the handset ringer is on.
• Make sure the telephone line cord is connected firmly 
to the base and the telephone jack.
• Make sure the AC adapter is plugged firmly into an 
outlet not controlled by a wall switch.
• You might be too far from the base;move closer.
• You might have too many extension phones on your 
telephone line to allow all of them to ring. Try 
unplugging some of them.
If you hear noise or interference when using the phone:
• Make sure the base antenna is fully upright.
• You may be out of range. Move closer to the base.
• Press and release C to change to another of the 
30 channels available. If noise is exceptionally loud, 
move closer to the base before changing channels.
• Household appliances plugged into the same circuit as 
the base can sometimes cause interference. Try moving 
the appliance or the base to another outlet.
• The layout of your home or office might be limiting the 
operating range. Try moving the base to another 
location,preferably on an upper f loor.

base for at least 15 seconds.
If you hear other calls while using your phone:
• Press C to change to another channel.
• Disconnect the base from the modular jack and plug in 
a corded telephone. If you still hear other calls,the 
problem is probably in your wiring or local service.
