Scan Functions, continued 23
NOTE 2:
1. Signal detection (stop scan on detected carrier) is
dependent upon the strength of the signal, the squelch
control setting, and the status of the preprogrammed
subaudible tone squelch decoder (CTCSS “off” or “on”).
2. Press the / buttons during scan to reverse the
direction of scan, if desired. When starting a scan, the
direction is always the same as the last time a scan was
ended.
3. To interrupt a scan on either receiver, first press the
A / B
A
button to select the particular receiver. Press the
3
MEM
,
2
VFO
, or
1
PRIO
to exit the scan mode for that se-
lected receiver.
4. While one receiver is being scanned, the opposite
receiver (transceiver) can be operated in the normal
mode, or set to scan simultaneously.
5. The receiver can be tuned during scan, if desired. It
may be useful to tune away from an active frequency,
to resume scanning, for example (in all scan stop
methods except SEEK). A frequency can also be
entered during scan (press
NUM
*
followed by numeric
entry). After the carrier drops (CARRIER and RESUME) or
timeout (TIME) on the tuned frequency, the scan will
resume within the programmed (in SETUP) range limits.
Press and hold the
2
VFO
button to start a VFO scan. Press

3
MEM
button to start a Memory scan. In all
cases, prior to starting a scan, adjust the SQUELCH
control for the appropriate receiver to a setting that just
quiets the receiver.
