Radio Functions
Tone Signaling
To help block out unwanted calls to your ProLine ML3215 / ML3245 can be programmed to look
for privacy 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
icon will show in
the lower right 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 can 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. Priority channel activity takes precedence over
all other conversations. During the scan mode, if a P-T-T is initiated the radio will transmit on 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 Lookback 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
A selected channel becomes the “Priority” channel. As you change the channel, that channel’s frequency will become your
new Priority channel. Priority channel activity takes precedence over all other conversations.
Nuisance Delete
During receiving a signal or scan delay time, if the MON (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.
Marked Idle
When used in conjunction with Busy Channel Lockout (BCLO), the radio will allow a transmission if the correct tone is present
with the received signal.
TX Delay
The transmission will remain active for approximately 180 milliseconds even though the P-T-T bar is released when using
CTCSS Tones. This eliminates squelch tail.
Time-Out-Timer (TOT)
The purpose of the time-out-timer is to prevent any single person from using a channel for an extended period. The time-out
time can be programmed from 10 seconds to 990 seconds.
Time-Out-Timer Penalty (TX Inhibit)
When time-out-timer is applied, transmission will be inhibited after the time-out-time time expires. This TX
inhibit time can be selected and programmed by your radio communications Dealer from 1 second to 100 seconds. For
instance, when the time-out time is set to 3 minutes and T-O-T penalty is set to 5 seconds, if you continuously transmit for 3
minutes, the radio will stop transmitting. A tone will sound with each P-T-T bar press until the 5 second TX inhibit time expires.
