Kestrel Instruments Support & FAQs

Why am I seeing a "Magnetized Batteries" error message on my unit?

This message means that your batteries interfered with compass calibration. To solve this issue insert battery shim, rotate batteries, and try again. If this condition persists, try using a different battery brand. NK recommends Made in the USA Energizer® Brand Ultimate Lithium AAA batteries for improved reliability, capacity, cold-weather performance and weight.
