Chap3：Functionality
1、 WITH the host transceiver distance in about 0m~2m, and press the menu button, return, pairing
2、 .Paring need within 5s, over time 10s
2) 、Power management
1、Neither voice function nor paring, no press key, then switch to lower power consumption
standby mode in 20s
2、Remote controller open voice function, but no voice input nor transmission, then shut down
voice function in 5 minutes and switch to lower power consumption standby mode
3、In standby, press any key to awake device, the responded time required to be less than 300ms
4、Usually in standby mode, press key to awake device, voice function kept and step to sleep mode
once communication is finalized
3)、 Power consumption
1、Standby：Current <20uA。
2、Voice communication：<30mA。
3、Press key or paing：<20mA。
