“We’ve had very little bad weather here which is quite unusual. We’ve only had 2 thunderstorms since July. The few times when there were storms out there, the unit has worked great!”

Lightning Safety Tip:
ThunderBolt® Noise Test
When Do You Need to Run a Noise Test?
IMPORTANT! Each ThunderBolt® has a NOISE TEST completed prior to shipping, so it is not vital to run a test before the unit's first use. In fact it is recommended that you allow the ThunderBolt® to operate with the pre-installed NOISE TEST at your location to see if you have any interference problems.
What you will be watching for is the ThunderBolt® false triggering (displaying storm activity when there are no storms in your vicinity). These false-positive signals are caused by electronics in the operating vicinity of your ThunderBolt®.
If you experience false-positive signals please follow the below instructions.
What to do if you think your unit has been desensitized.
If a NOISE TEST is performed at a location when it is not necessary, it is possible to accidently lower the detection
sensitivity of the unit.

If a NOISE TEST is performed at a location when it is not necessary, it is possible to accidently lower the detection
sensitivity of the unit.
1.) DO NOT RE-RUN THE NOISE TEST AT THE SAME LOCATION.
(This could make the problem worse rather than better)
2.) The simple solution is to move the ThunderBolt® to a different location without any electronics in close vicinity or storm activity within a 50 mile radius and re-run the NOISE TEST two successive times.
(This could be taking the ThunderBolt® to a quiet location within the building or just outside).
This will return the unit to it's factory settings. (Running the noise test twice in a row insures that the noise test level is reduced completely to zero)
3.) Return your ThunderBolt® to it's original location WITHOUT running another NOISE TEST.
