Automatic Shutdown
SureCall boosters that have automatic shutdown work in the following way:
3.
The cellular side (LEDs 4 and 5) is usually the first side to experience
oscillation. When oscillation is detected in the uplink and/or downlink, the
appropriate red
Warning
LEDs flash and
Power
(LED 3) turns red.
4.
If oscillation occurs on the PCS side, LEDs 1 and/or 2 blink as appropriate and
Power
(LED 3) turns red due to cellular oscillation.
5.
If the problem is not resolved, the affected side shuts down after 30 seconds.
In general, the cellular side oscillates more easily than the PCS side.
6.
The booster wakes up and
Power
(LED 3) turns green. If oscillation resumes,
the LEDs flash as described previously. These 30-second cycles continue for
15 minutes or until the problem is resolved.
7.
If the problem is not resolved within 15 minutes, the booster shuts down
automatically (all LEDs OFF except
Power
, which is red) and must be reset by
unplugging the booster from the power supply and plugging it back in.
8.
To resolve oscillation, increase antenna separation and/or the attenuation (see
the table on page 7).
