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.
