A few practical examples:
• Turning all switches OFF = 0 dB attenuation (booster is at full gain).
• Turning ON switch #1 in a bank = 1 dB attenuation (booster maximum gain is reduced by 1 dB).
• Turning ON switches #1, 3, and 5 in a bank = 1+4+16 dB attenuation = 21 dB attenuation. For example, in an 80 dB
booster, the selected channel is reduced to 59 dB (80 dB -21 dB).
• Turning ON all switches in a bank = 1+2+4+8+16 dB attenuation = 31 dB attenuation. For example, in an 80 dB
booster, the selected channel is reduced to 49 dB (80 dB-31 dB).
When the booster is powered on, the green Power light should illuminate.
• If any of the bands are oscillating, the corresponding band lights will ash red and the corresponding band(s) will
shut off.
Note: When the booster is turned on, the band lights will ash red and yellow for approximately 10 seconds.
Note: In general, the uplink and downlink DIP switches should be set identically but this is not always the case.
5.4 LED Conditions
This section will help you interpret the LED indicators on your Force8. But rst, here are a few conguration and testing
points to keep in mind:
• When choosing a location for the outside antenna, a minimum signal reading of –100 dB is needed. A signal in the
-70 dB to -90 dB range is recommended for best performance. A signal stronger than -70 dB may cause the affected
frequency bands to stop amplifying.
• The booster gain dials should be at maximum level unless the control light for a specic frequency band is ashing
red or red-yellow. In either case, try increasing the antenna separation between the inside and outside antennas as
much as possible rst, and then restarting the booster.
• Avoid setting the gain below 35 dB, as this could cause the affected frequency band to stop amplifying.

Additive combination effects:
• Switch 1 (1 dB) + Switch 2 (2 dB) = 3 dB attenuation
• Switch 1 (1 dB) + Switch 2 (2 dB) + Switch 3 (4 dB) = 7 dB attenuation
• Switch 1 (1 dB) + Switch 2 (2 dB) + Switch 3 (4 dB) + Switch 4 (8 dB) = 15 dB attenuation
• Switch 1 (1 dB) + Switch 2 (2 dB) + Switch 3 (4 dB) + Switch 4 (8 dB) + Switch 5 (16 dB) = 31 dB attenuation
