IV. Post-Installation Examination and Troubleshooting
Check by following the steps below after the installation:
1.
Check if there is GSM900 (2G) signal from outside, and if the outdoor antenna's signal is
stable. The outdoor antenna must face either the base station or the signal source. If the
received signal is still weak after the installation, try to adjust the antenna angle of PA400
and check if the indicator of the AMPC1 works normally.
2.
If the strength of the received signal is constant, it means this Kit is functioning properly. A
weak signal means insufficient or saturated AMPC1 that requires some adjustment by
increasing or decreasing the AMPC1. In a situation where the 80% of the indoor signal can
be received, the increase of this Kit will not boost the signal obviously. It will even cause
interference and/or decrease the signal quality. In a situation where only 20% of the indoor
signal is received, a tremendous improvement of signaling quality can be expected by
using this Kit .
