When the display becomes dim or turned off, battery replacement is necessary. Unscrew and
remove the back cover. Replace with fresh Lithium battery CR2032 or equivalent. Use a small
metal tool (such as tweezers or screw driver) to momentarily short circuit the AC pads. Re-screw
the back cover. A compass calibration should be done every time the battery is replaced.
