16信道，高容量锂电池
低电压警功能
内置CTCSS/DCS
可避免收听到相同频率上的不相关呼叫。
超时定时
超时定时器的作用在于防止单个对讲机长时间占用某个信道。同时避免对讲机由于长时间持续发射而造成损坏。
高/低功率输出选择
每一个信道功率都可以通过写频软件进行调整，当通讯范围较小时，可转换为低功率，有效节省电池能量。
自动省电功能 
在未***到信号或无操作时，对讲机将进入省电模式以降低电池耗电量，从而延长对讲机的使用时间。
紧急报警功能
遇紧急情况或突发事情，按下报警键立即会以最大音量发出报警。
VOX声控功能
无需按PTT键，开启声控功能便可进行通话，非常适合在某些特殊的场合下，用户的双手被占用时使用。
