Battery Saving
a.ON: Entering into the battery saving state automatically without any operation for 10 seconds,
b.OFF: Battery saving is off.
Busy Channel Lockout (BCL)
Switch on or off each effective channel busy lockout function via PC programming software. Whenopen this setting, signal from the curr
ent channel is banned to transmit.
Beep
a. The beep is on, and the "Di" sounds is emitted for every rotation of the channel
b. The beep is off, and no "Di" sounds for every rotation of the channel
Low Battery Voltage Warning
When the voltage is lower than the preset value, a prompt "Please change battery" is issued every 5 seconds, press the PTT button is in
valid and makes "Di" sounds.
Time-out timer
The function of the time-out timer is to prevent the speaker from using a channel too long and continuously, and the interphone emits
continuously too long and the body heats up. If you continuously transmit the interphone, the TOT limit time set by the machine is
exceeded; the transceiver will stop transmitting (the time can be programmed by computer while the factory setting time is 1 minute).
Release the PTT button and press PTT again to resume transmitting.
QT / DQT
The radio's QT/DQT for each channel can be program by software. When the channel set the QT/DQT, the radio squelch open only if it
receives a signal that uses the same QT or DQT. The radio squelch does not turn on if the same channel uses different QT / DQT calls,
only lights in green, sub-CTCSS 50 groups, and digital sub-audio DCS 105 groups.
Note: Although using a channel with CTCSS / DCS sub-audio may be preferable to receiving unwanted calls, it does not mean your call is
a secret.
