A red light indicates a feedback loop condition called oscillation. When oscillation is detected, your booster shuts down or reduces gain. This is typically caused when the outside antenna and the inside antenna are placed too close together and noise is created on the system.
To correct this: First, unplug booster. Next, relocate the outside antenna and inside antenna further from each other. The objective is to increase the separation distance between them so they won't create a feedback loop reducing the gain and coverage area of the amplifier.
TECH TIP: Vertical separation of the two antennas typically requires a shorter distance than horizontal separation. If possible, try placing the device antenna directly below the location of the tower antenna. In addition, a combination of vertical and horizontal separation distance also works to prevent oscillation.
Finally, plug booster back in and run a test. if the red light displays again, increase the separation distance until the condition is corrected.
If lights are blinking green and red, test your inside signal coverage WITHOUT the signal booster. Conditions may have changed (a new cell tower installation, for example) to provide adequate coverage for your needs without a booster.
With the eqo Booster, you may start with a green light and see a blinking red light for roughly 7 seconds before it goes to either a solid green or solid red. If it ends up solid red, refer to the steps indicated above to resolve (unplug booster from power, separate antenna further apart from booster unit or create some shielding between the two units, then plug back in). If it ends up solid green, test your coverage - you may have enough for what you need!
