Repeater operation
turn on/turn off repeater
Press “power switch to the ”one” direction to turn on, then the speaker will make a sound, the
‘PWR’ indicator turning red, device start working, the system is going to stand by condition.
Audio, data transmit
Repeater receive the upstream RF signal, automatically control the transmitter (excitation module
and power amplifier module) to transfer, which will enhance the received signal to increase
communicate distance.
Indication of transit
1) ‘A’ and ‘B’ indicator turning light when device is working, indicate the signal is digital,TS1 is
during communication when ‘A’ turning light,TS2 is during communication when ‘B’ turning
light.
2) ‘TX’ and ’RX’ indicator turning light or ‘A’ and ‘B’ not turning light, indicate the signal is
analogue signal.
