1. Power on with 220V AC at the premise of no fault
being found in inspection. The glowing indicator light
shown as in the above diagram is means the power
supply works normally.
2. If the reverse antenna is mounted correctly, the
Downlink power indicator light should be on. In this
case, the covering area of the equipment shall be
larger than that in the technical specifications.
3. If the required covering area is too large and the
Downlink power indicator light is off after powering
on, it means that the input power is not sufficient
and the position of the reverse antenna should be
adjusted to receive more strong downlink signals.
4. When the debug is completed, select more than 20
points in the covering area to test the signal level
and talking effect of the mobile phone. It should be
ensured that the signal bar shall be fully filled with
strong signal in 90% of the covering area, and less
than 5% of the covering area can have two signal
bars. Meanwhile talking clearly and no interruption
occurs.
5. Switch off and then power on, check whether it is
normal. Then test with mobile phone, the working
state shall remain same as the original. Keep it
running for one to two hours around for further test.
6. Recheck the whole system and clean up the
working site.
7. Record the work and fill in the Engineering Records
Form in details and make the archives as well.
Notice:
1. The signal amplifier must be put into operation as per
the above mentioned steps strictly.
2. Ensure safety of the equipment and personnel. Be sure
that there is no connection fault before powering on.
3. Well Record the process and any fault shall be reported.
5.4 System maintenance
The strict power supply protection and power protection
measures in the design of the signal amplifier assure high
reliability of the equipment. When it is put into operation,
rarely is manual maintenance required. But for assuring the
high reliability of the communication in the covered area, it
is recommended to check them half a year regularly, which
shall include:
1. Check the reverse antenna system: find out if the
antenna orientation or position is changed, or if the bolt
is unfastened or loosened.
2. Check the indoor covering system: find out if the lines
are removed or if the fixed devices are loose and if
power is well connected. Remove the potential hazards
as early as possible, if any.
3. Check transmitting power: find out if the panel indicator
lights of the signal amplifier are working normally. The
power indicator light should be on and the Uplink and
Downlink power indicator lights should be on as well.
4. Timely remove the malfunction if any. Record the
maintaining process and fill in related forms.
