Priority Scanning
When Priority Scan is turned on, the scanner checks the
conventional priority channels in the unlocked banks every 2
seconds or the priority ID’s in trunked systems every 4
seconds between transmissions. If a signal is present on a
priority channel, the scanner switches to monitor that
transmission, even if it had been stopped on another channel.
One channel or talkgroup ID in each bank is designated as
the priority.
To turn on Priority Scan, repeatedly press PRI until the
scanner displays PRIORITY ON. To turn Priority Scan off,
repeatedly press PRI until the scanner displays PRIORITY
OFF.
Note: If all priority channels in unlocked banks are locked
out, the scanner displays ERROR when you try to turn
on the priority scan mode.
Priority Plus Scanning
To scan only the priority channels in the unlocked banks,
while scanning repeatedly press PRI until the scanner
displays PRIORITY PLUS. To turn off Priority Plus, repeatedly
press PRI to select PRIORITY ON or PRIORITY OFF.
Note: Priority Plus only operates in the scan mode; not in the
hold or search mode.
Listening to the Input Channel
Repeater-based systems, such as public safety conventional,
trunked systems, and some other business and amateur radio
systems, use two sets of frequencies – input frequencies and
output frequencies (see “Understanding Scanning”). You
normally listen to the output frequency, as it can generally be
received from a much farther range. Sometimes, though, you
might want to know if the mobile unit is nearby. To do this,
check the input frequency by pressing REVERSE. If you hear
the transmission, then the mobile unit is probably within 2 or 3
miles of your location.
