• Do not expect to see 5 bars of reception everywhere in the building as this is practically
impossible. Also, signal strength in dB can vary significantly without necessarily affecting the
number of bars displayed because different phone and data card manufacturers handle bars
slightly differently.
• A good rule of thumb is that increasing gain by 6 dB doubles the coverage distance of the
interior antennas. Start at the lowest gain setting and increase gain gradually as needed.
• If one or more red
Warning
lights comes on, that indicates that there’s oscillation in that band
and the band will immediately shut down. If the dB gain is not adjusted, the
Warning
light will
continue flashing. The booster will power down and will then wake every 30 seconds for the next
15 minutes to see if the problem has been resolved. If the problem hasn’t been resolved after 15
minutes the band will shut off and the booster will need to be turned off and turned back on to
reset.
• You may see oscillation in any of the bands (see Section 5.6).
• If you can’t get the system to work properly, you may need to install an additional interior
antenna and/or a different type of interior antenna and/or relocate interior antennas.
Note
: In general, the uplink and downlink DIP switches should be set identically but this is not always
the case.
5.6 - Automatic Shutdown
If equipped, the Force7 booster includes an automatic shutdown feature that works in the following
sequence:
1. When oscillation is detected in the uplink and/or downlink, the appropriate
Warning
light(s) will
begin flashing red and the
Power
light (light 5 in the diagram on Page 18) remain green.
2.
If oscillation occurs on any other band, lights 6 and/or 7, 8, 9, and 10 will blink as appropriate.
3. If the electrical current powering the booster is too weak or too strong the lights will blink yellow.
4.
If the problem is not resolved, the affected side will shut down for 30 seconds.
5. The booster will wake back up. When this occurs, the power light will be green. If oscillation
resumes, the lights will flash as previously described. These 30-second cycles will continue for
15 minutes or until the problem is resolved.
6.
If the problem is not resolved within 15 minutes, the booster will shut down (all lights off except
the
Power
light, which is green) and must be reset by unplugging it from the power supply and
plugging it back in.
