A scan is a scan of a list of scans set on the current channel.Supports mixed analog and digital channel scanning
Emergency Alarm
In the event of an emergency, you can use this feature to ask your fellow or control center for help. Emergency alarm
has the highest priority。
VOX
When the microphone detects that the voice reaches the level to trigger the voice-activated transmission, the
walkie-talkie automatically transmits the voice。

The Busy Channel Lockout is prevent interference with other users that are transmitting on the same channel.
Transmit time-out
timer(TOT)
The TOT is over the time of a single transmits (the default is 60 seconds), the walkie-talkie will automatically
terminate the transmits and issue a warning sound.If you need to transmits again, please transmits after the preset
time.
Power Save
The walkie-talkie enters the power save mode after preset time in standby mode。

damaged or dirty.
Clearing the contact. Please get contact with our
distributor to repair, if you cannot solve it.
The sound is small/
intermittent, or on sound
when receiving the signal.
Battery voltage is low.
Charging or change a new battery.
The voice is too small.
Turn up the sound.

Clear the speaker. Please get contact with our
distributor to repair, if you cannot solve it.
Cannot talk with the members
in the same group
The frequency is different with other
members.
Resetting the same frequency with them.
In the different digital or analog
channels
Correct to the same channel.
Too far away from each other
Get close with each other
Single call or group call does
not work in the digital channel
Be different in the
frequency/channel/color code/ time
slot
Setting the same frequency/channel/color code/
time slot
Other sound in the channel,
which is not from the
members
Interference from the same frequency
Change to new frequency, or correct the squelch
The signal is not set yet.
Set the signal for all radio in the group
The loud noise
Be too away from other members.
Get close with other members.
Poor location, such as blocked by tall
buildings, or located in the basement
Move to open environment, restart the radio.
Interfere by the environment or
electromagnetic
Avoid the device interfering the radio
