 installation.
♥ ALC technology used to provide auto amplitude fixing.
♥ Modules structures,making it convenient for installation,debugging and maintenance.

♥ Plug power adaptor into AC power socket and finish installation

 Technique Supporting:

♦ If still no signal receipt after activated repeater, please check if outdoor antenna point to

 

signal tower or elsewhere have strong signal and check if strength achieve -70DBM.

 

♦ Please adjust the direction of outdoor antenna if it cannot call out

 

♦If strength is not steady, please check if outdoor and indoor antenna are too close.
