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.
 
Remote Kill, Remote Stun and Remote Revive
You can remote kill, stun or revive another radio with our smart BF-990, which brings more efficiency and safety into your work, especially when you are working with a team.
 
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.
