If you have difficulty operating this phone, try the suggestions below. If you still have trouble, call 1 800 722-9125.

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.

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 batteries might need recharging.

If the handset battery status icon is partly displayed, the battery needs recharging.

Make sure the battery pack is installed correctly.

If the battery pack will still not charge, replace it with Lucent Technologies Replacement Battery 4051.

If the above suggestions do not solve the problem, try resetting the security code (see next section).

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 while attempting to dial. Move closer to the base and try the call again.

If moving closer to the base does not help, the handset and base might be set to different security codes.

To reset the security code, try the following:

Place the handset in the base, and check to make sure the CHARGING light is on. Wait 15 seconds, then pick up the handset and press P. The phone should operate properly. If it does not, try the next step.

Place the handset in the base, and check to make sure the CHARGING light is on. Unplug the AC adapter from the outlet, wait 15 seconds, then plug it in again. The CHARGING light should go on. Wait another 15 seconds, then pick up the handset and press P. The phone should operate properly. If it does not, try the next step.

Pick up the handset, open the battery compartment, and unplug the battery pack. Wait 15 seconds, then re- install the battery pack, close the battery compartment, place the handset in the base, and check to make sure the CHARGING light is on. Wait another 15 seconds, then pick up the handset and press P. The phone should operate properly.

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 you wiring or local service. Call your local telephone service company.

If you hear noise or interference when using the phone

You may be out of range. Move closer to the base.

Press and release Cto change to another of the 25 channels available. If the 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 floor.

If the phone does not ring when you receive a call

Make sure the handset ringer switch is set to ON.

Make sure the telephone line cord is connected firmly to the base and the telephone jack. Make sure the power cord is plugged into an outlet not controlled by a wall switch.

You might be too far from the base. Move closer to the base.

You might have too many extension phones on your telephone line to allow all of them to ring. Try unplugging some of the other phones.

Press Cto change to another channel.

If you hear other calls while using the phone

Press Cto change to another channel.

Disconnect the base from the telephone jack and plug in a corded telephone. If you still hear other calls, the problem is probably in your wiring or local service.

Call your local telephone service company.

If your telephone misdials or

you don’t hear the other person right away

It might take a few seconds for your handset to find a good con- nection to the phone system. While it is searching, the PHONE light blinks rapidly. Do not start dialing until the PHONE light is on steadily.
