SCANNING
You must adjust the squelch to the threshold point
for proper scan operation. You cannot use scan in
conjunction with the tone alert function.
1 Hold/Resume Programming
22
This transceiver provides two types of scan hold/
resume:
Time Operated Scan
The transceiver stops scanning on a busy channel,
remains there for approximately 5 seconds, and then
continues to scan even if the signal is still present.
Carrier Operated Scan
The transceiver stops scanning on a busy channel
and remains there until the signal drops out. It
allows a 2 second delay before resuming scanning to
prevent losing the station when operators change.
The transceiver is delivered from the factory in the
Time Operated Scan mode. Use the following
procedure to switch between modes:
Hold/Resume Selection
Press and hold the 5 key and turn on the power.
Note
1 In CTCSS operation, scan will stop only on
signals that contain the proper CTCSS code.
2 In DTSS operation, scan will stop (without
squelch turned off) whenever it receives a
signal. However, squelch will not open until
the proper DTSS signal is received.
3 In combined CTCSS and DTSS modes,
scanning stops when the proper CTCSS tone
is received. Squelch will open only if the
DTSS signal matches when the scan stops.
2 Scan Options
The following scan options are available:
@ Memory Scan
Scans through those memory channels that have
data stored and that have not been locked out. This
function operates only in the memory mode. (page
20)
mg Band Scan
Scan proceeds over the entire band. This function
operates only in the VFO mode. (page 24)
