Busy Channel Lockout
If enabled via the programming software, this feature can prevent your radio interfering with other
transmitting radios on the same channel. If you hold down the PTT key while the channel is in use, your
radio will keep beeping, 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
This feature can be enabled via the programming software. 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.
