* CTCSS/CDCSS and STE
The integrated CTCSS/CDCSS/STE protects you from unnecessary interference from other communication activities at the same frequency. You only communicate with your target radios.
* DTMF, 2 Tone, 5 Tone
Such functions enable flexible and versatile calling procedures.
* Kill, Stun and Revive
You can remotely kill, stun or revive another radio with BF-990, which ensures communication security when a certain radio is lost.
* Emergency Alarm
BF-990 keeps your safety in mind. Should any emergency rises, press the emergency alarm button and the radio will immediately transmit a signal for help to your colleagues.
* Busy Channel Lockout (BCL)
This prevents the user from transmitting on an already busy channel, and thus increases the user's work efficiency.
* Time-out Timer (TOT)
This function limits the transmitting time for each PTT press and effectively prevents a channel from being unnecessarily occupied by mistake.
* PC Programming
The user can program his radio on the computer via a programming cable.
