Busy Channel Lockout
If enabled via the programming software, this feature can prevent
your radio interfering with other transmitting terminals on the
same channel. If you hold down the PTT key while the channel is
in use, your radio will keep beeping and display text information
“Channel Busy!”, alerting you to transmission prohibition. To stop
beeping, please release the PTT key. When the channel is free,
you can press and hold down the PTT key to transmit.
Time-out Timer (TOT)
The purpose of TOT is to prevent any user from occupying a
channel for an extended period. If the preset time expires, the
radio will automatically terminate transmission and keep beeping.
To stop beeping, please release the PTT key. You must wait for
a certain time period (preset by your dealer) to initiate another
transmission.
Functions and Operations
If the pre-alert function is set by your dealer, your radio will alert
you to the TOT expiration in advance.
Note: This feature is null in Emergency mode.
Pseudo Trunking
If your radio operates on a channel with this feature enabled
and one time slot is already occupied, it can transmit and receive
on the other free time slot, allowing you to communicate timely
under emergent situations.
MIC AGC
If enabled via the programming software, your radio will process
the audio signals during transmission, providing improved audio
for the receiving radio.
Emergency Footswitch
This feature must be realized through further development.
After successfully developed, you should request your dealer to
enable it via programming software. This feature is quite useful in
emergent situations to avoid any unexpected loss.
Note: Emergency footswitch will be unavailable
if the Emergency feature is not enabled on
the current channel.
