Classification Description
A zone is a group of channels.The radio supports 16
zones and contains up to 4000 channels.
The power level is for the transmission power level of the current
channel, which can be set to high or low power.
When the terminal scans a signal on a channel, it will stay on the
channel to listen, so as to understand the current activity status of
the relevant team members.
Emergency alarm has the highest priority.
The radio transmits when voice is detected by the microphone
Busy channel lockout prohibits transmission and prevents i
nterference to other users when the radio is receiving traffic.
When a transmission times out, the terminal will automatically terminate
the transmission and issue a warning sound.
Keyboard lock is used to lock keys to prevent inadvertent key operation.
The radio may be set to automatic or manual lock mode.
Power saving is a preprogrammed function based on time that places
radio into a sleep-wake mode to conserve the battery.
Private call is a one-to-one call.
Group call is a one-to-many call.
All call is a call to all contacts on the current digital channel.
Talk around allows communications on the repeaters output frequency.
TDMA direct mode is used to divide a direct channel (simplex) into
two time slots to allow efficient channel usage. Multiple parties may share
the channel without interference depending on slot setting.
An analog call is a call on an analog channel.
This setting exhibits an open squelch condition where both traffic
and noise can pass to the speaker.
Squelch level allows the manual setting of the squelch from 1 to 9.
This controls at what point that audio can be sent to the speaker.
The default value is 4. The lower the set value, the more chance
of noise and weak signals being heard.
Monitor allows the user to open the receiver squelch manually
to listen to on-channel signals.
CTCSS / DCS are analog signaling methods used in transmit and receive.
They are typically set to the same value for transmit and receive. Only
signals that match the preprogrammed values will pass to the speaker.

DTMF signaling:
Users can set and program the DTMF signaling via PC software to disable or enable some advanced function of
radio.
Note: This option only applies to analog mode.
