OPERATING THE TRANSCEIVER

SCANNING CHANNELS

ENVOY™ TRANSCEIVER REFERENCE MANUAL 33

Scanning channels

If you intend to receive calls on several channels, switch on scanning. When scanning

is switched on, the transceiver sequentially selects each channel/mode in your scan

tables to detect incoming calls. The channels are scanned in a continuous cycle. By

default, mute is switched on automatically when scanning is switched on.

NOTE: Only those scan tables that are set to be scanned have the channels

scanned.

By default, when the transceiver detects a call addressed to your station, it stops

scanning and notifies you according to the type of call received. When you press

to end the call, scanning resumes. If you do not press this key to end the call, or any

other key within a pre-determined timeout, the transceiver automatically ends the call

and resumes scanning.

NOTE: The default standby state for the transceiver is to return to scanning so

that it is ready to receive calls across a range of frequencies.

When the transceiver detects a signal, it notifies you according to the mute setting

selected. If your transceiver is set to notify you when voice is detected (V), you can

pause scanning, select the channel/mode on which the voice was heard, then resume

scanning when required. Voice mute also detects calls that are addressed to any station

on the scanned frequency, and any other channel disturbances. If your transceiver is

set to Selcall mute (S), it only pauses scanning when it detects a call addressed to your

station, regardless of the call system used.

Your choice of Voice or Selcall mute depends on whether or not you have to detect

voice signals, and how much noise and traffic you want to hear.

It is recommended that scanning is switched on when you are not using the transceiver

to communicate so that you are able to receive calls on any frequency in the scanned

scan tables.
