Steps that describe the work of Repeater.

1) The outside antenna receives the signal from the nearest mobile base station.

2) The outside antenna sends the received signal through the coax cable to

the installed Repeater.

3) The Repeater accepts the low signal and improves it.

4) The improved signal goes to the inside antenna through the connection coax cable.

5) The inside antenna send the improved good signal to your mobile phone.

Installation Approaches:

1) Fix up outdoor antenna reception on housetop

or outside the window and point it to the signal tower.

2) Connect outdoor antenna to 'BTS' port in repeater machine through cable.

3) Connect indoor antenna (s) to 'MOBILE' port in repeater machine through cable also.

4) Plug power adaptor into AC power socket and finish installation.

Technique Supporting:

1) 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 -50DBM.

2) If can not call out, please adjust the direction of outdoor antenna.

3) If strength is not steady, please check if outdoor & indoor antennas are too close.

Please ensure the outdoor and indoor antennas have distance of 10 meters at least.

with a wall between and not in a same horizontal line.
