Check battery" or "Warning! Use Rechargeable Batteries Only" is displayed on screen

•Non-rechargeable batteries have been installed. They must be removed immediately and replaced with rechargeable NiMH batteries (see page7).

•Rechargeable batteries have been installed but may be old or need to be replaced. Remove and re-install the batteries and use normally until fully discharged then let them fully recharge in the handset or base.

•If the above measures do not correct the problem, your batteries should be replaced (see page 7).

Telephone does not work at all

•Make sure batteries are installed and charged correctly (see page 7).

•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 you have dial pulse telephone service, make sure the dial mode is set to dial pulse (see page 17).

•If these suggestions do not work, unplug the base, remove and re- insert the batteries, then place the handset in the base to re-initialize.

Phone does not ring

•Make sure the ringer is on (see page 15).

•Make sure the telephone line cord and AC adapter are plugged in properly (see page 6).

•Make sure the base antenna is fully upright.

•Move the handset 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 them.

If you hear noise or interference during a call

•Make sure the base antenna is fully upright.

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

•Appliances plugged into the same circuit as the base can cause interference. Try moving the appliance or 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 buttons don’t work, try placing the handset in the base for at least 15 seconds.

•Disconnect the base from the modular jack and plug in a corded tele- phone. If calls are still not clear, the problem is probably in your wiring or local service. Call your local telephone service company.
