Maintenance Method Of Signal Amplifier

First check the outdoor antenna, especially the Yagi antenna, because the Yagi antenna is directional, so make sure that its position has not changed, and whether the installation screws are loose.
After checking the outdoors, check the indoors, whether the wiring is installed properly, and whether the power supply is connected properly. If there is a potential safety hazard, you can prevent it before it happens.
Then look at the main unit of the mobile phone signal amplifier, and see if the indicator lights on the panel are normal. Normally, the uplink and downlink power should be on.
Finally, if a fault is found, it must be maintained and repaired in time.
