9 SCAN

Scan is a useful feature for hands-off monitoring of your
favorite frequencies. Becoming comfortable with all types of
Scan will increase your operating efficiency.
This transceiver provides the following types of scans.
Scan Type

Band Scan

Scans all frequencies on the current band.
Scans all frequencies stored in the
Memory Scan
Memory channels.
Scans memory channel in the plural
Group Link
memory groups registered in the group
Scan
link list..
Scans all frequencies within the
Program Scan
programmed range, on the current band.
Scans all frequencies within a 1 MHz
MHz Scan
range from the originating frequency.
Scans the Call channel as well as the
Call Scan currently selected VFO frequency or
Memory channel.
Priority Scan checks the Priority Channel
Priority Scan
every 3 seconds.
Note:
◆ Adjust the squelch level before using scan. Selecting a squelch
level too low could cause scan to stop immediately.
◆ While using CTCSS or DCS, scan stops for any signal received;
however, scan will immediately resume if the received signal
does not contain the same CTCSS tone or DCS code that you
selected.
◆ Pressing and holding [PTT] causes scan to temporarily stop if it
is functioning on a non TX band.

SELECTING A SCAN RESUME METHOD

The transceiver stops scanning at a frequency or Memory
channel on which a signal is detected. It then continues
scanning according to which resume mode you have
selected. You can choose one of the following modes.
Time-Operated mode
Scan will stop temporarily once the squelch opens. Scan will
resume 5 seconds later (default setting) regardless of the
squelch status.
Carrier-Operated mode
Scan will stop temporarily once the squelch opens. Scan
will resume if the squelch remains closed for more than 2
seconds (default setting).
Seek mode
Scan will complete once the squelch opens, and it will not
resume.

Scan Range
Time-Operate Resume Time
Set the hold time for the Time-Operate scan method.
When a signal is received, scan will pause at that frequency
for the duration of the hold time you set. When the set time
elapses, scan will resume (even if the signal is still being
received).
1 Access Menu No. 132.
2 Set the resume time to 1 ~ 10 sec.
Carrier-Operated Resume Time
Set the hold time for the Carrier-Operate scan method.
When a signal is received, scan will pause at that frequency.
When the signal stops, scan will resume after the duration of
the hold time you set.
1 Access Menu No. 133.
2 Set the resume time to 1 ~ 10 sec.
BAND SCAN
Band scan monitors all frequency range that is stored in
Menu No. 100 (Programmable VFO), using the current
frequency step size.
1 Select your desired operation band and frequency.
2 Press [VFO] (1s).
Band scan appears and scan starts at the current
frequency.
• The 1 MHz decimal point blinks while scanning is in
progress.
Note:
◆ When starting a scan within the frequency range of the
registered program scan memory, it is the program scan.
3 To quit band scan, press [VFO].
