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 Scan Range Band Scan Scans all frequencies on the current band. Memory Scan Scans all frequencies stored in the Memory channels. Group Link Scan Scans memory channel in the plural memory groups registered in the group link list.. Program Scan Scans all frequencies within the programmed range, on the current band. MHz Scan Scans all frequencies within a 1 MHz range from the originating frequency. Call Scan Scans the Call channel as well as the currently selected VFO frequency or Memory channel. Priority Scan Priority Scan checks the Priority Channel 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. 1 Access Menu No. 130. • In digital (DV/DR mode), access Menu No. 131.

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
Scan Range
Band Scan
Scans all frequencies on the current band.
Memory Scan
Scans all frequencies stored in the Memory
channels.
Group Link
Scan
Scans memory channel in the plural
memory groups registered in the group link
list..
Program Scan
Scans all frequencies within the
programmed range, on the current band.
MHz Scan
Scans all frequencies within a 1 MHz range
from the originating frequency.
Call Scan
Scans the Call channel as well as the
currently selected VFO frequency or
Memory channel.
Priority Scan
Priority Scan checks the Priority Channel
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.

Select your desired operation band and frequency.
2
Press and hold
[VFO]
.
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.
¡
During DR mode, press and hold [VFO], the DR scan menu
screen will appear on the display. (refer to page No.16-14 )
