OPERATION

CONFIRMATION TONES

When you press a button, the phone sounds a confirmation tone to indicate that it accepted the command. If you are out of range or there is too much in- terference, the phone sounds an error tone. Move the handset closer to the base and try again.

MAKING/RECEIVING A CALL

To make a call, lift the handset from the base. If you do not hear a dial tone, press TALK. When you hear a dial tone, dial the phone number.

To answer a call, lift the handset from the base. If you do not hear the caller, press TALK.

Note: If you accidentally press TALK within 2-3 seconds after answering a call, the phone ignores your command. After 2-3 seconds, pressing TALK dis- connects the call.

When you are finished with the call, ei- ther press TALK or return the handset to the base to hang up.

CHANGING CHANNELS

To reduce interference and get the clearest communications between the base and handset, the phone automati- cally selects a clear channel for a call at the beginning of the call. The phone uses one of 25 channels when you hear a dial tone or during a call.

However, you can manually change the channel the phone is using during a call. When you press CHAN, the phone changes to another channel and uses that one.

Note: If the handset is too far from the base, the phone might not change channels. Move closer to the base and try again.

USING REDIAL

To redial the last number dialed, press REDIAL on the handset when you hear a dial tone. The phone automatically dials the last number dialed.
