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.
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.
