Scan Operation - Kenwood TK-630 series Instruction Manual

4-4. SCAN OPERATION
4-4-1.
General
There are two "mic hook" scan modes in which the radio can be programmed
to operate.
@
On Hook Scan:
Normal method of scanning that requires the microphone to be on hook (in
the mic hanger) to initiate scan, and for channel scanning to occur.
The microphone does not have to be on hook to initiate scan or to scan
channels. Off hook scan should be used on radios implementing a
microphone headset or handset that use a combined PTT/hook switch.
Off Hook Scan:
(1)
The scan feature is enabled by pressing the front panel SCN switch.
(2) A
single confirmation tone sounds, and scanning starts. If there is one or
(3) The display shows SCAN (or
SC) and the SCAN (SCN) indicator lights.
(4) If the transceiver receives a signal while scanning, the scanning stops
less added channels, an error tone sounds, and scanning does not start.
temporarily, the audio is unmuted, and the channel is displayed.
1.
If the channel is not the priority channel and there is a priority channel,
the radio receives the signal alternately between the channel and the
priority channel.
2. If the channel is the priority 2 channel and there is a priority
1
channel,
the radio receives the signal alternately between the priority 2 and the
priority
1.
3. If there is no priority channel, the scanning stops at that channel and
receives only that channel.
(5) If the SCN switch is pressed again, an operation confirmation tone sounds,
and the scanning ends (scan mode is exited). (The channel selected
immediately before the scanning began returns.)
4-4-2.
To transmit while scanning.
On Hook Scan
(1)
Take the microphone off hook. The radio goes to the off-hook revert
channel.
(2)
When the PTT switch is pressed, transmission takes place on the displayed
revert channel.
Off Hook Scan
Upon pressing PTT, the radio ceases scanning and goes to the off-hook
revert channel on which transmission begins immediately.
4-4-3. To
delete nuisance channels while scan
is on.
( 1 ) To temporarily delete undesirable channels, press the D/A switch 2 seconds
while the channel is active (indicated by the display).
A confirmation tone sounds, the currently displayed channel is deleted, and
the scanning resumes. The last channel in the scan sequence cannot be
deleted. (The priority channel can only be deleted if the "priority temporarily
delete" feature is enabled in the "scan information" programming.)
(2) To restore the original scan list, either turn scan off and on
or
turn the radio
oft amd on.
