* Monitor

When the signal is weak, the user can activate this feature which will enable BF-870S to pick to the weakest signals on the current channel.

 

* Scan

When the user activates this feature, BF-870S will scan all the pre-defined channels on the radio and the user can easily access any communication activities on any channel.

 

* Hands-free VOX

The user can initiate transmission with his voice, instead of pressing the PTT button. This function helps to liberate your hands so that you can focus better on your missions. The feature can be activated only with paired BelFone earpieces.

 

* PC Programming

The user can connect the BF-860 to a PC and preset the radio according to his communication needs.

 

* Squelch Levels (0-9)

This helps minimize interferences from unwanted weak signals and gives you a better audio experience.

 

* TOT

By limiting each transmission time, Time-out Timer prevents channels from being unnecessarily occupied by mis-operation and thus improves channel efficiency.

 

* Wide/narrow Bands Switchable

The user can preset the bandwidth of each channel ( 25KHz or 12.5KHz) according to his communication needs, which delivers flexible and easy migration of channel spacing requirements in any situation.

 

* Low Power Alert

When the battery gets too low, the LED light on the top of the radio will flash red and the user should start recharging his radio.

 

* Auto Power Save

When BF-860 is not transmitting or receiving signals and when there is no operation, it automatically switches into power save mode to extend battery standby time.

 

* CTCSS/CDCSS and STE

This can effectively prevent interferences from other conversations at the same frequency. 

 

* Built-in Flashlight

The built-in flashlight is designed to bring more convenience to the user when the user is working in a dark environment.
