Battery Installation and Replacement
To install or replace the batteries in this Kidde CO alarm, please perform 
the following steps. 
1. Slide open the bottom cover to expose the battery compartment.
2. If replacing batteries, remove the old batteries and properly dispose 
of them as recommended by the battery manufacturer.
3. Install the new batteries. Note the polarity 
illustration in the battery compartment. 
4. Close the bottom cover. Note: The bottom 
cover will not close if all AA batteries are not 
installed.
When replacing the batteries, use one of the 
following approved Alkaline brands: 
 • Duracell  MN1500 or MX1500 
  • Energizer  E91 
  • Gold Peak 15A 
  • Golden Power GLR6A 
These batteries can be purchased where you bought the alarm or at a 
local hardware store. Use of a different battery may have a detrimental 
effect on the alarm operation.
NOTE: Do not use LIthium batteries in this unit.
IMPORTANT: Constant exposures to high or low humidity may reduce 
battery life. A good safety measure is to replace the battery at least 
once a year, or at the same time as you change your clocks for daylight 
saving time.
After installing or changing the batteries, reinstall your alarm. Test 
your alarm by using the Test/Reset button and check that the green LED 
flashes once approximately every 60 seconds.
Low Battery HUSH® CONTROL
When the batteries need to be replaced, the unit will produce a low 
battery warning. The Low Battery HUSH® feature allows you to press 
the button on the alarm and disable the “chirp” for a random period of 
up to 12 hours. This gives you a chance to replace the battery at a more 
convenient time by disconnecting the alarm from power. During this Low 
Battery HUSH® period, your alarm is monitoring for CO.
