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. 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 The transceiver remains on a busy frequency or Memory channel for approximately 5 seconds, and then continues to scan even if the signal is still present. Carrier-Operated mode The transceiver remains on a busy frequency or Memory channel until the signal drops out. There is a 2 second delay between signal drop-out and scan resumption. Seek mode The transceiver remains on a busy frequency or Memory channel even after the signal drops out and does not automatically resume scanning. 1 Access Menu No. 130. Note: ◆ In digital (DV/DR mode), access Menu No. 131. 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. 3 To quit band scan, press [VFO]. 2 Set the Scan Resume mode to [Time] (Time-Operated), [Carrier] (Carrier-Operated) or [Seek] (Seek). 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. MEMORY SCAN Use memory scan to monitor all Memory channels programmed with frequency data. 1 Press [MR] (1s). Scan starts at the current memory channel. 2 To quit memory scan, press [MR]. Note: ◆ At least 2 Memory channels must contain data and must not be locked out of scan. 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. 22

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.
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
The transceiver remains on a busy frequency or Memory
channel for approximately 5 seconds, and then continues to
scan even if the signal is still present.
Carrier-Operated mode
The transceiver remains on a busy frequency or Memory
channel until the signal drops out.
There is a 2 second delay
between signal drop-out and scan resumption.
Seek mode
The transceiver remains on a busy frequency or Memory
channel even after the signal drops out and does not
automatically resume scanning.

[Carrier] (Carrier-Operated) or [Seek] (Seek).
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).

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.

Band scan appears and scan starts at the current
frequency.
•
The 1 MHz decimal point blinks while scanning is in
progress.
3
To quit band scan, press
[VFO]
.
MEMORY SCAN
Use memory scan to monitor all Memory channels
programmed with frequency data.
1
Press
[MR] (1s)
.
Scan starts at the current memory channel.
2
To quit memory scan, press
[MR]
