Low Battery Indicator
Note: The Low Battery indicator “ ” only appears in the main display
when the unit is in the power ‘Off’ mode.
• If you install a 9-Volt battery in the Sure
Alarm circuit as described above, the
Low Battery indicator disappears.
• If the Low Battery indicator remains ‘On’,
this indicates that either you have not
installed the 9-Volt battery, or that the
9-Volt battery is exhausted and needs
to be replaced.
• If the Low Battery indicator ‘flashes’, this
indicates that the 3-Volt lithium battery
is getting weak and should be replaced
as soon as possible.
Instructions for changing the lithium battery will be found on page 31, 32 of this
manual.
