Interference
The detector features enhanced interference rejection capabilities to prevent
false lightning detection. When the detector cannot detect lightning due to
interference from nearby equipment, the detector sounds a single audible beep
and displays "UNABLE TO DETECT…PLEASE RELOCATE."
Use the detector at least 3 feet away from sources of interference, including:
• Electric motors (windshield wiper motor or fan motors in cars, hard drive and
optical drive motors on your PC and AV equipment, well pumps, sump
pumps)
• CRT monitors (PC monitors, TV's)
• Fluorescent light fixtures (turned off or on)
• Microwave ovens (while in use)
• PC's and mobile phones
WARNING: Take shelter IMMEDIATELY when lightning is present, whether or
not it has been detected by the Lightning Detector. If you are concerned about
lightning strikes, follow all safety precautions to keep yourself and others safe.
DO NOT rely on this Lightning Detector as your only source for warnings
about potentially deadly lightning strikes or other severe weather conditions.
