Designation Description
Automatic Shutdown
SureCall boosters that have automatic shutdown work in the following way:
1. The cellular side (LEDs 4 and 5) is usually the rst side to experience oscillation. When
oscillation is detected in the uplink and/or downlink, the appropriate red Warning LEDs
ash and Power (LED 3) turns red.
2. 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.
3. If the problem is not resolved, the aected side shuts down after 30 seconds. In general,
the cellular side oscillates more easily than the PCS side.
4. The booster wakes up and Power (LED 3) turns green. If oscillation resumes, the LEDs
ash as described previously. These 30-second cycles continue for 15 minutes or until
the problem is resolved.
5. 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.
6. To resolve oscillation, increase antenna separation and/or the attenuation.
If you Want to Improve Coverage
• Find a location that receives a stronger signal and relocate the outside antenna to
that location.
• Increase the distance between the outside and inside antennas.
Be sure your signal booster’s dB gain is turned up to maximum gain on each dial (see
page 16).
