STEP THREE - MAINTAINING YOUR PLB
1. Routine Maintenance
Carefully inspect the beacon case for any visible cracks. Cracks may admit
moisture, which could falsely activate the beacon or otherwise cause a
malfunction. Any cracks observed should be immediately referred to ACR for
evaluation by calling +1 (954) 981-3333. ACR Technical Support can also be
reached by sending an email to
After checking the beacon case for cracks, it may be wiped down with a clean,
damp cloth. Do not use any type of cleaner on your beacon.
2. Battery Replacement
Replace the battery no later than 6 years from date of manufacture, 5 years
from date of install, or after emergency use. At each inspection, check the time
remaining until replacement is required. The battery should be replaced if the
beacon has been activated for any use other than the Self-test. Always refer
battery replacements and other beacon service to a factory authorized Battery
Replacement Center. Battery replacement includes servicing the beacon by
replacing all o-rings, testing the water seal and the electrical properties.
NOTE: There are no user serviceable items inside the beacon. DO NOT OPEN
THE BEACON. Opening the beacon will void the warranty.
