NORMAL SCAN
When you are operating the transceiver in VFO Mode,
3 types of scanning are available:  Band Scan, Program
Scan, and MHz Scan.
BAND SCAN
The transceiver scans the entire band of the frequency
you selected.  For example, if you are operating and
receiving at 144.525 MHz, it scans all the frequencies
available for the VHF band.  (Refer to receiver VFO
frequency range in the specifications {page 72}.)  When
the current VFO receive frequency is outside the Program
Scan frequency range {below}, the transceiver scans the
entire frequency range available for the current VFO.
1Press [VFO] and turn the Tuning control or press Mic
[UP]/[DWN] to select a frequency outside of the
Program Scan frequency range.
2Press [VFO] (1s) to start Band Scan.
•Scan starts from the current frequency.
•The 1 MHz decimal blinks while scanning is in progress.
3Press any key other than [F] or [  ] (Power) to stop
Band Scan.
Note:
◆The transceiver scans the frequency range that is stored in Menu
No. 7 (P.VFO) {page 61}.
◆If you select a frequency within the L0/U0 ~ L2/U2 range in step 2,Program Scan starts.
PROGRAM SCAN
You can limit the scanning frequency range.  There are
3 memory channel pairs (L0/U0 ~ L2/U2) available for
specifying the start and end frequencies.  Program Scan
monitors the range between the start and end
frequencies that you have stored in these Memory
Channels.  Before performing Program Scan, store the
Program Scan frequency range to one of the Memory
Channel pairs (L0/U0 ~ L2/U2).
■Storing a Program Scan Frequency Range

Note:
◆The transceiver stops scanning when it detects a signal.
◆If more than 2 Program Scan channel pairs are stored and
overlaps the frequency range among the pairs, the smaller
Program Scan Memory Channel number has priority.
◆If the step size of the current VFO frequency is different from
that of the programmed frequencies, VFO Scan begins
instead of Program Scan.
◆To perform Program Scan, the “L” channel must be lower thanthe “U” channel.  Otherwise, Band Scan starts {page 40}.
MHZ SCAN
MHz Scan allows you to scan an entire 1 MHz frequency
range within the current VFO frequency.
1Press [VFO] and turn the Tuning control or press Mic
[UP]/[DWN] to select a frequency in which to perform
MHz Scan.
•If you want to scan the entire 145 MHz frequency, select
any frequency between 145.000 and 145.9975 MHz (for
example, select 145.650 MHz).  Scan will operate
between 145.000 MHz and 145.9975 MHz.  (The upper
frequency limit depends on the current frequency step
size.)
