4-5. SCAN
For proper scan operation the squelch must be adjusted
to the threshold point.
Scan cannot be used in conjunction with the Tone Alert
function.
4-5-1. Scan Options
The following scan options are available:
Band Scan
Scan proceeds over the entire main / sub band. This
function operates in the VFO mode only.
Programmable Band Scan
The scan range in this mode is specified in memory .
MHz Scan
Scans over a 1 MHz range.
Memory Scan
Scan proceed thru those memory channels that have
data stored and have not been locked out. This
function operates the in memory mode only.
VFO / Memory Scan

V/M/C (VFO/Memory/Call) Scan
Scans the VFO, the memory channel last used, and
the call channel.

4-5-2. _Hold/Resume Programming
Two type of scan hold / resume are provided in this
transceiver.
Time Operated Scan
In this mode the radio stops on a busy channel,
remains there approximately 5 seconds, then
continues to scan even if the signal is still present.
Carrier Operated Scan
In this mode, the radio stops scanning on a busy
channel and remains there until the signal drops out.
The radio allows a 2-second delay before it resumes
scanning so that you don't loose the station when
operators change.
NOTE
When the CTCSS is operating, scan will stop only on a signal which
contains the proper CTCSS tone.
With the DTSS in operation, scan will stop (with squelch turned
off) whenever it receives a signal. Squelch will not open, however,
until the proper DTSS signal is received.
With both the CTCSS and the DTSS on, scanning will stop when the
proper CTCSS tone is received. Squeich will open only if the DTSS
signal matches when scan stops.
