Before you begin

This cordless telephone operates within the maximum power allowed by the Federal Communications Commission (FCC). Even so, this handset and telephone base can communicate over only a certain distance

which can vary with the locations of the telephone base and handset, the weather, and the construction of your home or office.

If there is a call while the handset is out of range, the handset might not ring — or if it does ring, the call might not connect when you press PHONE/

FLASH. Move closer to the telephone base, then press PHONE/FLASH to answer the call.

If the handset is out of range during a telephone conversation, there might be interference. To improve reception, move closer to the base.

If you move out of range without pressing OFF/CLEAR, your telephone will be disconnected after five seconds.To hang

up properly, walk back toward the telephone base, periodically pressing OFF/CLEAR until the call is disconnected.
