The alarm is timed to activate at 12 months. Once this time has elapsed, the pilot will light up every 10 seconds during
the fi rst 4 days. Subsequently, the fl ashing will be every 30 seconds for the next 9 days.

If not, the battery should be replaced with a new one. The remaining time for the alarm activation is saved.
The battery life for normal use is approximately 3 years.
The battery is CR2032 type.
Remove the battery protection for activation.
