Base - larger AA rechargeable batteries
: The Base unit requires 4 recharge-
able
2400
NiMH batteries
.
Unlike the Pendant battery - these are readily
available in many retail stores. These are to provide you with up 24 hours
of battery back-up protection in the event of a power failure. They will not
be damaged by continually charging in the base unit.
These should have been installed for you during the set-up. If they are not
installed, simply follow these directions here.
When you first get your unit - these
batteries will probably be low, or even
fully discharged - and will need to be
charged overnight before being able to
provide you the 24 hour battery back-
up protection.
Unscrew the cover on the bottom of
the Base unit with the supplied screw-
driver. 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 “Running on battery power”. This
will continue once every minute for the first 15 minutes, then once every
30 minutes until power is applied through the power adaptor - or until the
batteries are depleted. (If you do not hear anything - this simply means
your batteries will need to be fully charged overnight. Or it may mean that
you have already plugged in the power adaptor - which is why it would not
announce “Running on battery power”.
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.
