  2. Gently lift the white tab to release the battery from the back cover.
  3. Place the new battery in the back cover, with the positive (+) side down.
  4. Make sure the rubber gasket in the front cover of the MOB tag is not broken and is fully seated in its groove.

    The gasket fits in the groove in a specific orientation.

    NOTICE

    If the gasket is not properly and fully seated in the groove, it does not create a seal, which leads to the failure of the MOB tag when it is exposed to water. See the Field Service Manual at garmin.com/manuals/force_current_trolling_motor for information on purchasing a replacement gasket.

After you replace the battery, you may need to pair the MOB tag again.
