readings must be b05 and +15 dBm. Device Gain must be 65/65 dB. If the BS is lower than - 65dBm, the coverage will be

smaller. However, the device can work normally. If the BS is too weak, it'll be necessary to adjust the position of the outdoor

antenna by raising it as high as possible (on a pole on the rooftop) and pointing it towards the provider's nearest base station. If
the BS is higher than - 50 dBm, the device will have a self-excitation issue. In those conditions, the output signal will drop during

communications. If the two antennas are placed very close to each other, it will evoke self-excitation. To fix the problem, you
would need to place the outdoor antenna at the largest possible distance from the indoor antenna.

System Test

Check whether the coverage is good

1. If the signals in small parts of the area have not been improved, please check the following:

- Check whether the indoor antenna is installed correctly or not; you may try to change the antenna location to improve

coverage.

- Check if it is necessary to adjust the direction of the indoor antenna.
