5.7 SCAN FUNCTIONS

Scanning consists of sequentially searching up to 15 channels for a valid signal (RF, CTCSS or

DCS tone). When found the radio will stop on that channel until the signal disappears.

While listening on the channel, the User may PTT on that channel. After the signal disappears

the radio will remain listening on the channel for a short time (typically 3 seconds) before

resuming scanning.

If a

Priority/Emergency Channel is assigned, the radio will interleave a check of this channel

between each normal channel check. The radio may also check the Priority Channel every few

seconds while stopped on a channel. If a signal is found on the Priority Channel then the radio

will switch to that channel immediately.

To activate Scanning, select a

SCAN Channel.

5.7.1 Scan Screen

The display shows the name of the current Scan-Group

(e.g.

ScanChGrp), which may be changed using the ▼/▲

keys.

The Scan-Group Number is shown at the top-left of the

display (i.e.

1, 2, 3, 4) if it is a User Scan-Group, or blank

for Fixed Scan-Groups

. While the Scan Screen is

displayed the radio is scanning the shown group.

The RSSI indicator shows the received signal strength as the radio is scanning.

All other keys have the same assignments as in the Main Channel Screen.

When stopped on a channel, the name of the selected site, and the “rotating arrow” symbol is

replaced by the Speaker symbol.

To temporarily skip the channel from the Scan-Group, press

OK then select Skip.

Skipped channels are restored when a different Scan Group is selected or if Scan is exited. The

Priority Channel cannot be skipped.

OK: Edit is only active for User Scan Groups and opens up the Scan-Edit Screen for the

selected Scan Group allowing Channels to be added, deleted or set as the priority channel (see

below).

While listening on the channel, the User can PTT on that channel. After the signal disappears

the radio will remain listening on the channel for a short time before resuming scanning.

The Keypad may be used for quick channel change (e.g.

456#).
