AT&T 7720 OPERATING RANGE

25

This cordless telephone answering system operates at the maximum

power allowed by the Federal Communications Commission (FCC). Even

so, the handset and base can communicate over only a certain distance—

which can vary with the locations of the base and handset, the weather,

and the construction of your home or office. For best performance, make

sure the base antenna is fully upright, as shown in the INSTALLATION

section of this manual.

If the handset is moved to a point where the base and handset can no

longer communicate, you will be “out of range.” The handset will sound

two short beeps to indicate this when you try to make a call. Move closer

to the base to restore normal operation.

If you receive a call while you are out of range, the handset might not

ring—or, if it does ring, the call might not connect when you press P.

Move closer to the base, then press Pagain to answer the call.

If you move out of range during a phone conversation, you will

hear noise or interference. To improve reception, move closer to the

base.

If you attempt to hang up while you are out of range, the phone will

be left “off the hook.” To hang up, walk back into range, periodically

pressing Puntil the PHONE light goes off.

Changing Channels

This cordless telephone has an advanced 25-channel AutoSelect®feature

that minimizes the chance of interference. Every time you answer or

make a call, the AutoSelect feature searches for and selects a clear

channel.

In the unlikely event that you notice noise or interference while using the

handset:

1Press h.

2If the interference does not clear, continue to press huntil you

find a clear channel (your call will not be interrupted)

— OR —

Move closer to the base and press h.

NOTE: You must be within range of the base to change channels.
