Troubleshooting
I hear noise on the cordless handset and the keys do not work.
•Make sure the telephone line cord is plugged in securely.
Registration failed appears on the handset.
•Only one handset can be registered at a time. If you have multiple handsets to register, please follow the instructions on page 105 for the first handset. Once a handset has been successfully registered, repeat the steps for each handset that needs to be registered.
•Make sure that the telephone base, handsets and headsets are in idle mode when registering a handset.
•Follow the steps on page 120 for the common cure for electronic equipment, then try again to register a handset.
•If you have already registered the maximum numbers of handsets and/or headsets, you need to follow the deregistration instructions before registering a handset. Refer to Expand your telephone system on page 105 and Deregister handsets/headsets on page 107.
My headset does not work at all.
•Make sure the telephone line cord is plugged firmly into the telephone base and the telephone wall jack.
•Charge the headset in the headset charger for up to three hours.
•Unplug the electrical power to the telephone base. Wait for approximately 15 seconds, then plug it back in. Allow up to one minute for the cordless headset and 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.
•If the headset battery is completely depleted, it may take up to 15 minutes to charge the headset before the headset has enough charge to use for a short time.
•The headset battery may be defective. Contact our customer service for assistance.
I cannot dial out from my cordless headset.
•You must use a telephone on the same line to dial out. Once you have dialed the number, you can press 
on the headset to take the call. After the headset is activated, you can hang up the handset from which you dialed from.
•If other telephones in your home are having the same problem, the problem is in your wiring or telephone service. Contact your telephone service provider (charges may apply).
The blue or red light keeps flashing on the headset 
key.
•Different flashing patterns of the red and/or blue lights indicate different conditions of the headset. See Headset indicators on page 102.
