Replacing the home unit backup battery
The home unit is fitted with a backup battery pack which is accessible via
a flap on the underside of the unit. You will not normally need to access the
backup battery unless it requires replacement.
Note: Remove the mains power and telephone connections before proceeding.
To replace the backup battery
1 On the home unit rear panel, use a small Philips screwdriver to loosen and
remove the retaining screw from the battery
compartment cover.
2 Slide the battery compartment
cover in the direction of
the arrow shown upon it
and then lift it out.
3 Carefully unplug the
battery lead from the
home unit’s recessed
connector. You can now
remove the battery and replace
it with a new unit.
Remove the retaining
screw and slide off the
cover
4 Carefully attach the battery lead to the recessed three-pin connector within
the compartment. The home unit will begin to beep intermittently to signify
that it does not have mains power - ignore this for the moment - once power is
connected and the battery becomes fully charged, it will cease.
5 Replace the battery compartment cover. Press down on the end of the cover that is
furthest from the arrow and simultaneously slide the cover until it locks into place.
6 Replace and gently tighten the retaining screw.
Attach the battery plug
to the recessed three
pin connector
