6LifeSentry® v1.2-L4
Base - larger batteries: The Base unit requires 4 rechargeable 2400 mAH
NiMH batteries (included). Unlike the Pendant battery - these are readily
available. They will provide you with up 24 hours of battery back-up protec-
tion in the event of a power failure. They will not be damaged by continually
charging in the base unit. The ratings on these can be 2400 mAH or higher.

fully discharged - and will need to be charged overnight before being able
to provide you the 24 hour battery back-up protection.
Remove the cover on the bottom of the
Base unit. Install the 4 batteries as shown
in the plastic engraving in the battery
compartment area. A few seconds after
you install these, you might hear “Run-
ning on battery power”. When the unit is
operating on the backup batteries, it will
announce “Running On Battery Power”
twice and the RED Power LED will con-
tinuetoash.Ifpowerisnotrestored
with in an 8 hour period, the unit will
start to announce “Running On Battery
Power” once every 30 minutes until power is restored or the back up batteries
are depleted. (If you do not hear this announcement, and the Power LED is
on solid, that means that you have already plugged in the power adaptor).
NOTE: the voice prompts of “battery is OK” etc only apply to the pendant
battery - not to the status of the base unit’s batteries. It is recommended that
you replace the base unit batteries with a new set of similar batteries every
two years.
Master ON/OFF switch:
LifeSentry has a Master ON/OFF switch on the bottom of the base unit –
just left of the rechargeable batteries for the base unit. This switch controls
all power – back up batteries and power from the AC adapter. This switch
should be ON at all times while the unit is in use. This switch should only
be turned OFF if the LifeSentry unit is taken out of service – during trans-
portation or no longer needed.
