VIII RADIO FUNCTIONS

VIII.1 TONE SIGNALING

To help block out unwanted calls to your radio, the PL5151 and PL5164 can be programmed by your radio
communications
Dealer to look for tones.

VIII.2 SCAN MODES

Scanning is a Dealer programmable feature that allows you to monitor a number of channels. Your radio
communications Dealer will help you define a scanning mode and your channel "scan list".
Once the scan list has been established, initiate scan by pressing the SCAN button. The SCAN icon will show in the
upper left corner of the display to confirm radio scanning.

VIII.3 NORMAL CHANNEL SCAN

If a conversation is detected on any of the channels in the scan list, the radio will stop on that channel and you will
be able to hear the conversation. In normal scan, you will be able to transmit on that active channel during the
programmable scan delay time. (The scan delay time is the amount of time the radio will stay on that channel once
activity has ceased. Dealer programmable, 4 - 7 seconds is typical).
The radio will resume scanning once the scan delay time has expired, and will continue to scan until the channel is
changed. In scan mode, if radio power is turned off and on, the radio will return to the scan mode until a channel is
changed.

VIII.4 PRIORITY SCAN TX

A single channel may be programmed as the "Priority" channel. The radio will constantly monitor this channel
while scanning and when stopped on an active channel. If a call is detected on the priority channel, the radio will
automatically move to, and remain on, the priority channel. Priority channel activity takes precedence over all
other conversations. During the scan mode if a PTT is initiated the radio will transmit on the priority channel.
VIII.5 PRIORITY LOOK BACK SCAN
A single channel may be programmed as the "Priority" channel. The radio will constantly monitor this channel
while scanning and when stopped on an active channel. If a call is detected on the priority channel "during a
conversation", the radio will automatically move to, and remain on, the priority channel. Priority channel activity
takes precedence over all other conversations.
VIII.6 PRIORITY SELECT SCAN
The selected channel becomes the priority channel. As you change the channel that channels frequency will
become your new priority channel. Priority channel activity takes precedence over all other conversations.
VIII.7 VACANT CHANNEL SCAN
The radio will automatically scan for the first open channel. Once a channel is found normal scan operation will
take place. All radios you intend to communicate must be programmed for this same scan function.

VIII.8 NUISANCE DELETE

During receiving a signal or scan delay time, if the monitor button is pressed, the current receiving channel is
deleted in scan list and is no longer scanned. When the power is turned off and on, the deleted channel is restored to
the scan list.

VIII.9 BUSY CHANNEL LOCKOUT

When the RX signal is being received, the radio's transmitter is disabled. Dealer programming makes this feature
active or disabled.
VIII.10
MARKED IDLE
When used in conjunction with busy channel lockout, the transmitter is allowed to operate as long as valid RX tone
is received. Dealer programming makes this feature active or disabled.
