SRP9170/80 P25 Portable Radio – User Manual

Note: A Transmit Limit Timer may be setup that limits a continuous transmission on a

channel. The last 10 seconds before the timer expires may be accompanied by warning

beeps.

5.1.11 Scan/Vote Functions

The Scan/Vote Function allows the sequential searching of up to 16 channels if the selected

zone channel is programmed as a Scan channel, and 15 channels if the selected zone

channel is programmed as a Vote channel, for a valid signal (Carrier + CTCSS / DCS tone

for Analogue FM or Network Access Code for P25). When found, the radio will stop on that

channel until the signal disappears again.

To activate Scanning, select a channel that has been programmed as a Scan channel. Once

selected, the scanning will either start automatically, if programmed, or you will need to press

the programmed scan function key. (Field Programmer configurable).

If a selected zone channel is programmed as a Vote channel, the voting will start

automatically without any other user intervention.

While listening on the channel, the user is able to PTT on that channel. After the signal

disappears, the radio will remain listening on the channel for a short time (Field programmer

configurable, typically 3 seconds) before resuming scanning or voting.

If a Priority Channel is assigned to Scan mode, the radio will interleave a check of this

channel between each normal Scan channel.

5.1.11.1 Scan/Vote Screen

Scan can be started by:

(1) Pressing the function key that has been assigned the scan function

by the Field Programmer, or

(2) Selecting a zone channel that has been assigned to automatically

scan by the Field Programmer, or

(3) Under User Options menu, selecting the SCAN ON option.

Selecting a channel that is associated to a VOTING group, with Scan/Vote enabled in the

FPP starts the voting process.

The top line of the display still shows the name of the current selected channel. The second

line of the display shows the name of the current selected zone while scanning/voting.

The channel can be changed by using the ▼ and ▲ keys. Other channels may be either

Scan or Normal channels, depending on the radio’s configuration.

Scanning/Voting is indicated by a rotating arrow symbol.
