Common function description
The functions supported by the walkie-talkie are shown in the table below.
Name Function description
Squelch level Squelch level adjustment Squelch level adjustment is to adjust the signal strength required when
adjustment receiving a signal. The squelch level (0 open to 9 is the highest) is selected by the local environ-
ment, and 3 is generally selected.
CTCSS/DCS CTCSS/DCS is used to avoid listening to irrelevant calls of the same frequency. Only when the
transmitted CTCSS/DCS matches the received CTCSS/DCS digital, the walkie-talkie can listen
to the voice through the speaker.
TOT Timeout prohibition TOT timeout prohibition can limit the single transmission time (the default is
60 seconds) to prevent the communication parties from occupying channel resources for a long
time, and to prevent the terminal from being damaged due to overheating. After the duration of
pressing the [PTT] key expires, the terminal will automatically terminate the transmission and
emit a warning tone. If you need to talk again, please transmit after the preset time.
Power saving When the walkie-talkie has no receiving or transmitting, no button or knob operation reaches the
power saving time, it will automatically enter the power saving mode.
Low battery It is used to remind the battery to charge in time when the battery power is low. When the battery
warning is too low, transmission will be prohibited.
Emergency An emergency alarm is when you encounter an emergency, you can ask your companion or the
Alarm control center for help.
SCAN After scanning is turned on, the terminal will scan according to the scan list. When there is
activity on a certain channel, it will stay on the channel to listen, so as to understand the current
activity status of related group members.
BCL Busy channel lock BCL can prevent interference from other terminals on the same channel
during transmission. When other terminals occupy the current channel, press and hold the
[PTT] key, and the terminal will emit a "beep" tone, indicating that it cannot be transmitted. If the
current channel is free, press and hold the [PTT] key to start transmission.
Power level The power level refers to the transmit power level of the walkie-talkie, which can be set to high
power or low power. High power can increase the signal strength of the current transmitted voice
of the terminal, and it can also communicate with the remote terminal. Low power can save power.
MONI Monitoring MONI monitoring is a listening method used to receive more signals or weak signals.
It helps to distinguish and listen to the faint sounds in the speakers.
Channel Channel broadcast is used to indicate the sequence of the current channel.
