Install Batteries
Insert two AAA batteries (not supplied)
into the compartment as indicated by the
polarity symbols (+ and –) marked inside.
Notes:
• Replace the batteries if the
alarm sound weakens or
the LED flashes red.
• Dispose of old batteries
promptly and properly. Do
not burn or bury batteries.
• Do not mix old and new
batteries, different types
of batteries (standard,
alkaline, or rechargeable),
or rechargeable batteries
of different capacities.
• If you do not plan to
use the alarm for a month or longer,
remove the batteries. Batteries can leak
chemicals that can destroy electronic
parts.
