To make or answer a call, press TALK so the TALK key on the handset lights.

Notes:

If the phone is out of range of the base, the handset beeps three times and the TALK key turns off.

You can make or answer a call on a phone on the same line as the cordless phone, even if the ET- 545’s handset is away from the base.

The keypad on the handset turns off if no button is pressed for more than 10 seconds (but the TALK key remains lit).

To disconnect a call, press TALK so the TALK key turns off.

REDUCING

INTERFERENCE

The ET-545 automatically selects a clear channel at the start of each call. CH and the current channel number appear on the display whenever TALK is lit. Sometimes, however, the select- ed channel picks up interference dur- ing a call. To reduce interference during a call, press CH to switch to an- other channel (25 in all) until you re- ceive better reception.

USING REDIAL

Notes:

The redial memory holds up to 80 digits.

We recommend you not use REDIAL/PAUSE to dial numbers that include a tone entry (see “Using Tone Services on a Pulse Line” on Page 12).

The redial memory does not store a FLASH/DEL entry or any digits entered after you press FLASH/ DEL.
