Kenwood TH-26A - Manual (Page 28)

For proper scan operation the squelch must be adjusted
to the threshold point.
4-5-1. Scan Options
The following scan options are available:
Band Scan
Scan proceeds over the entire band. This function
operates in the VFO mode only.
Programmable Band Scan
The scan range in this mode Is specified in memory
channels 9 and 10.
MHz Scan
Scans over a 1 MHz range.
Memory Scan
Scan proceed thru those memory channels that have
data
stored and have not been locked out. This
function operates the in memory mode only.
VFO / Memory Scan
Alternate scanning of the VFO and the memory
channel that was last used.
CALL / VFO Scan
Alternate scanning of the call channel and the VFO.
CALL / Memory Scan
Alternate scanning of the call channel and the
memory channel that was last used.
V/M/C(VFO/Memory/Call) Scan
Scans the VFO, the memory channel that was last
used and the call channel.
4-5. SCAN
Two type of scan hold / resume have been provided in
this transceiver.
Time Operated Scan
In this mode the radio stops on a busy channel,
remains
there approximately 5 seconds, and then
continues to scan even if the signal is still present.
Carrier Operated Scan
In this mode the radio will stop scanning on a busy
channel and remain there until the signal drops out.
The radio allows a 2 second delay before it resumes
scanning so that you don’t loose the station when
operators change.
The radio is delivered from the factory in the Time
Operated Scan mode. To switch between the modes use
the following procedure.
When the CTCSS is operating, scan will stop only on a
signal which contains the proper CTCSS tone.
With the DTSS is operation, scan will stop (with squelch
turned off) whenever it receives a signal. Squelch will
not
open, however, until the proper DTSS signal is
received.
With both the CTCSS and the DTSS are turned on
scanning will stop when the proper CTCSS tone is
received. Squelch will open only if the DTSS signal
matches when scan stops.
