Q1. Why is there still no signal after installing the equipment?
1. Check the power on booster and power supply.
2. Check the connector of the outdoor antenna is tight or not.
3. Check the connectors of RF cable are tight or not.
4. Check the outdoor signal is strong enough or not.
5. Check to make sure the antenna is installed correctly.
6. Check the connector of an indoor antenna is tight or not.
7. Check the cable type is suitable or not.
Q2. Why the signal strength is too weak on the edge of the area?
1. Check the outdoor signal and antenna direction.
2. The check booster is the full gain or not.
3. Check all of the connectors are tight.
4. Change the location of the outdoor/indoor antenna.
5. Check the cable type is suitable or not.
6. Deploy more indoor antennas.
Q3. After running a booster, why the signals are not stable?
1. Checking the distance between donor antenna and server antenna is too close to each other?
Check the LED of the booster to make sure alarms are green.
2. Checking the signals from donor antenna whether to be stable or not?
3. Connect the system again if it is an incorrect connection.
Q4. Why the booster power LED is not bright?
1. Checking the input AC power range indicated on the power adapter whether is corresponding to the local power system.
2. Checking the power adapter whether connect the equipment correctly and stably or not.
3. Checking the power adapter whether damage or not. To test output voltage whether be corresponding to that indicated on a power adapter or not by a multimeter
