restore the receiving mode.
Low Battery Warning
Holding down
[PTT]
and if the
LED
flashes red, that indicates the battery level drops to the predetermined value. When
drops further, the transceiver stops transmitting and generates an alarm. Recharge the battery pack if this occurs.
Automatic Power Save
While transceiver is idle for 10 seconds, it automatically turns into power save mode. When an operation is performed or a
signal is received, it turns back on.
Scan Operation (Available in TH307E)
Scan is for monitoring activity on different channels. Switch the channel selector to position “S”, the transceiver
will start scanning by checking channel 1 to channel 15 and stop on a channel if a signal is present. Your dealer
can Lockout each channel so this channel will be skipped from scanning. And the scan operation can be preset
as Time-operated or Carrier-Operated Operation.
Time-Operated Operation
The transceiver stays on a busy channel for a period of time that is preset by your dealer. Then the scan
moves on even if the channel remains busy.
Carrier-Operated Operation
The transceiver stays on a busy channel until it is no longer busy. Then after a delay time that is preset
by your dealer, the scan moves on.
Priority Scan
When the radio stays on a non-priority channel, it checks regularly the Priority channel that is preset by
your dealer. Once a signal is received on the Priority channel, the transceiver will quickly switches to that
Priority channel.
Channel Lockout
Your transceiver’s scan operation will skip those Locked out channels, if programmed so.
Revert Channel
When
[PTT]
is pressed while scanning, the transceiver stops scanning and jumps to that
REVERT
CHANNEL
to transmit. The
REVERT CHANNEL
can be programmed by your dealer.
