VIII. Radio Functions
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.
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.
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.
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.
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.
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.
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.
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.
Busy Channel Lockout
When the RX signal is being received, the radio’s transmitter is disabled. Dealer
programming makes this feature active or disabled.
