Kenwood TH-27A - Manual (Page 24)

When the CTCSS is operating, scan will stop only on a
signal which contains the proper CTCSS tone.
With the DTSS in 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 on scanning will
stop when the proper CTCSS tone is received. Squelch
will open only if the DTSS signal matches when scan
stops.
NOTE
4-5-3. Band Scan
1. Adjust the SQL control to the threshold point.
2. When one of the PRG-1, the PRG-2, or the MEMO
indicator has been lit. press the SCAN key in the VFO
mode. The MHz indicator begins flashing to indicate
that the radio is scanning.
3. Scan will begin in an upwards direction. You can
reverse the direction of scan by turning the Tuning
control .The tuning step size depends on the current
Frequency Step selection.
4. Scan stops on a busy channel, i.e. a station strong
enough to open squelch and turn on the BUSY
indicator.
5. Press the PTT switch or SCAN key to stop scan.
• The Lower and the Upper Scan Limits Entry
Select a frequency to be the lower or the upper scan limit.
Press the M key for longer than 1 second, and then press
the below key.
4-5-4. Programmable Band Scan
Limit
Programmable band
scan 1
Programmable band
scan 2
Upper 4/PROG-1 key 5/PROG-2 key
Lower 7/SEEK key 8/CAR key
• Confirmation of the lower and upper frequency limits
Hold the F key down for longer than 1 second, then press
one of the keys listed above. The upper or lower
frequency limits will be displayed as VFO frequency.
NOTES
1. If the step size of the lower limit frequency is differ­
ent from that of the upper limit frequency, Pro­
grammable band scan will not start.
2. If the lower limit frequency is equal to or higher than
the upper limit frequency, Programmable band scan
will not start.
