Auto-call function
After turning on the power switch, when turn the selector, it with tone calling,
from 1 channel to 16 channels, which enables you to select the channel conveniently.
Monitor/squelch function OFF.
To receive the weak signals, the channels doesn’t work or no signals to adjust the
volume by this function.
Instant squelch function OFF: press to receive the background noise, release to get
back the operation station.
Scan
1. If transceiver was set up at least 2 channels to scan, after pressing scan key
for 1 second, the transceiver will check the channels automatically until check
the signal to stop. Meanwhile it stay this channel until the signal disappear,
if the signal disappear at once, the transceiver will stay for 5 second then
scan.
2. when scan, LED glitters green, if receive signal, LED displays green(not glitter).
If you want to stop scan, press scan switch for 1 second again. The channel
of transceiver will stay the coder’s channel.
3. press PTT keypad to transmit, the transceiver will choose the channels, which
is the latest used.
QT/DQT
QT/DQT signals would be set up by the dealer. QT/DQT coder is mute volume/ coder,
it enables you ignore the same channel to call other people.
If one channel is set up the QT/DQT coder, it just can receive the exact frequency
or coder’s signal to use squelch. So, QT/DQT mode same as your transceiver of the
broadcast station just receive your signal. The squelch would not opened, if other
use different QT/DQT in the same channel to call, so you will not listen the call,
it enables you ignore these calls. It seems like you have personal channels with
QT/DQT, but, if others set up the same QT/DQT, they still can hear your call.
Time-out timer
The Time-out Timer (TOT) limits the time of each transmission. The built-in time-out
timer limits each transmission time to a maximum of 300seconds. Just before the
transceiver stops the transmission, a warning beeps sounds. It is necessary to
protect the transceiver from thermal damage. You can turn this function OFF.
Battery power-saving
When it doesn’t receive the signal or doesn’t operate (don’t press keypad, don’t
turn switch), the battery power-saving can reduce power. When the channels is no
t busy and not operated for 5 seconds, the battery power-saving turned on, when
