Batteries - Fireco Deafgard Operating Manual

Batteries

If the screen displays "BATT", it means
there are approximately 7 days of battery
life. In this case, we recommend to change
the batteries immediately.
Only use alkaline batteries and do not
use re-chargeable batteries.
The batteries supplied should last at
least 12 months. Deafgard regularly checks
the battery life.
