WARNING
Never remove the batteries from a
battery-operated alarm to stop an
unwanted alarm (caused by cooking
smoke, etc.). Removing batteries disables
the alarm so it cannot sense smoke,
leaving you at risk.
The alarm will not operate without
battery power. The alarm cannot work
until you install the batteries in the
correct position (Match “+” to “+” and “-”
to “-”).
This device contains lithium batteries. If
tampered with, the battery may be short
circuited and create a risk of fire. Never
attempt to open or damage the alarm.
Replace all batteries at once and only use
new, unused batteries, as replacements.
REPLACING THE BACKUP BATTERIES
1. Remove your Nest Protect from its backplate.
2. Using a Phillips screwdriver, unscrew the two
screws from the battery door on the back of
Nest Protect.
3. Replace the batteries. Make sure to use
Energizer Ultimate Lithium batteries and
install them in the right order. If you install
them out of order, you may not be able to
close the battery compartment.
4. Reattach the battery door by sliding it into
the tabs located on the opposite side from
the batteries, replacing the screws and then
reattaching Nest Protect back to its base.
5. Press the Nest button to run a test.
