How To Troubleshoot SureCall Flare, Flare 3.0, and Flare DB+ Signal Boosters

Jun 23, 2020

Watch video below that shows how to trouble-shoot SureCall FlareDB+, Flare 3.0, and SureCall Flare home / office / building cell phone signal boosters. Find out what the LED indicator lights green, yellow, and red indicate about how cellular amplifier is performing and what you can do to improve its performance, if needed.

Above video goes through troubleshooting the SureCall Flare Series signal boosters by explaining all the lights and what they indicate.

There are three lights on the front of your Flare. The power light and two indicator lights, which tell you how the booster is functioning or if it has cut back on its gain or output power.

Power light.

Let us start with the power light. If it is on, your booster is powered up and working. If it is not, you need to plug the booster into power; that us it. Pretty simple.

Left indicator light.

The left indicator light tells you if the booster is utilizing the built-in AGC or automatic gain control. This is a powerful bit of technology that automatically adjusts your booster's output power or gain based on a number of factors in your cellular environment. If the left indicator light is flashing yellow, that just means the booster is self adjusting for Optimal Performance. This is part of normal operation and means your booster is working.

If the light is flashing red, your booster is receiving too strong of an incoming signal, which has caused the booster to shut down. If this happens, you can resolve the issue by relocating outside Omni antenna (75 Ohm) in SureCall Flare kit to a location with weaker signal. If you're using a Yagi antenna (75 Ohm) in case you have SureCall Flare DB+ or Flare 3, aim that antenna away from the tower until the red flashing stops.

Right indicator light.

The right indicator light deals with separation between the Flare booster unit and outside antenna. If the right indicator light is flashing yellow, the system is boosting the signal but at a reduced power level.

If you're happy with your coverage, there's nothing more you need to do. If you would like to increase the coverage area, simply move the outside antenna or Flare booster further apart from one another to improve the booster's performance.

If the right indicator light is flashing red and yellow, the system is experiencing oscillation or feedback and may have shut down on a particular band. It is not currently boosting your signal for that band.

To fix this issue, move the outside antenna and booster further apart from one another. Reset the booster by unplugging it and plugging it back in and then check the lights.

  • Hello, I have the SureCall Flare 3.0 My separation is about as far away as I can get, approx. 35-6 feet, between booster and antenna. First of all, can I add, say 10 feet of good quality TV coaxial cable to the 50 foot coax that was included? Also, is it possible that the yellow light on the left side (for automatic gain control) can just continue flashing? The unit has been plugged in for almost an hour, and it is still flashing.

  • This is how you provide help with troubleshooting. I see many user manuals that are very short on details and you often have to go on YouTube to find someone who has made a video dealing with the problem. I like that has these videos on particular models along with written explanations of what to look for.

  • I never thought that signal boosters would be easy for people to install themselves or that troubleshooting can be easy. I think there are situations where you might need a professional to help, but it’s nice knowing that troubleshooting isn’t any harder than troubleshooting a TV or Blue-Ray (at least it looks that way to me).

  • I find it a bit ironic that the devices we use to make life easier often require occasional troubleshooting. I run into it occasionally whether it’s my cable box, smart TV, or laptop that needs updates or a reboot. What makes things different from when I was younger is that I usually don’t need anyone to help me with the troubleshooting because things have become so user-friendly. No surprise then that signal boosters may need occasional trouble-shooting, but that the problems are easy to resolve.

  • In my experience, trouble-shooting comes up infrequently with most gadgets but when it does, you need to be prepared. I’m more likely to buy a gadget if I know its troubleshooting system is user-friendly.
