CHAPTER 6: TESTING AND TROUBLESHOOTING
6.1 Band LED Conditions
This section will help you interpret the LED indicators on your GuardianA. But first, here are a few configuration and testing points to keep
in mind:
• If the control light for a specific frequency band is flashing red or red-yellow, try increasing the antenna separation between the inside
and outside antennas as much as possible first, then restarting the booster.
• Attenuation can be lowered to a maximum of 25 dB through sentry software and maximum of 31 dB using the booster’s dip switches.
• Attenuation greater than 25 dB (either made by the booster’s dip switches or cumulative adjustments of dip switches and software)
will cause the affected band to shut off and display a solid red led.
6.2 LED Conditions
LED INDICATIONS
LED
Color LED
Condition
Resolution
-- OFF Normal operation. When the light is off, it means things are normal and that the band is active.
Yellow Solid Normal operation. The frequency band is not in use. Eventually, the band will enter sleep mode.
Yellow Flashing Normal operation. The Automatic Gain Control (AGC) is self-adjusting.
Red Solid The associated frequency band is off. If the red light flashes for a long time (caused by too much signal), and then
turns solid red, it means the associated frequency band has been turned off. This will happen if the gain dial for that
frequency band has been turned all the way down.
Yellow/
Red Flashes
alternating
colors Self-oscillation has been prevented.
Increase the separation between the inside and outside antennas. If your booster kit uses two directional antennas
(example: outside Yagi antenna and inside panel antenna), ensure that they are facing away from each other.
If the condition continues, increase attenuation in small increments until the light turns off or flashes yellow.
Refer to your Sentry Monitoring Software for more information about LED codes. Meanwhile, if you have any questions during
setup, please reach out to our U.S.-based support technicians:

6.3 Testing & Troubleshooting
Once the booster is powered on (and no Warning lights are on), assess the signal in locations of needed signal improvement.
Refine the antenna locations and/or gain levels as needed, then complete the permanent installation when you are confident
the system will perform well.
A few tips and some perspective:
• It’s not realistic to expect full reception everywhere in the building.
• As a general rule, increasing gain by 6dB doubles the coverage distance of the interior antennas. Start at the lowest gain
and increase gradually as needed.
• If one or more red Warning lights comes on, it indicates there is oscillation in that band and adjustments are needed
• If you can’t get the coverage reasonably well-balanced, you may need to install an additional interior antenna and/or a
different type of interior antenna and/or relocate interior antennas.
