Internal Battery Change/Insertion

Tools needed:
Phillips Head
Screwdriver
Warning! Before attempting to replace the battery pack (ZOLL PN 703-0731-01), make sure that
external power is disconnected and the unit's Power Switch is set to "OFF".
Procedure:
Remove the four (4) 6-32 x 5/16 Phillips Pan Head screws
located at the bottom of the unit. This will release the
Battery Pack Compartment Cover and expose the Battery
Pack and its integral mounting bracket.
While holding the Battery Pack in one hand, pinch the
connector plug locking latch while pulling outward. This
will release the plug from its mating socket and free the
Battery Pack.
Replace the old Battery Pack with a new Battery Pack.
Align the plug, then insert the Battery Pack into its mating socket. The plug and socket are
keyed to protect against misconnection.
Momentarily turn the unit's POWER switch to its "ON"
position to confirm operating power. A DISCONNECT Alarm
will sound.
Turn the unit's POWER switch to its "OFF" position.
Secure the Battery Pack with its integral mounting bracket to
the unit's Lower Case using the four (4) 6-32 x 2 1/4 Phillips Pan Head screws.
Warning! Make sure that none of the Battery Pack wires get pinched between the bracket and
case enclosure.
Align the Battery Pack Compartment Cover and secure it with the four (4) 6-32 x 5/16 Phillips
Pan Head screws.
Momentarily turn the unit's POWER switch to its "ON" position to confirm operating power.
A DISCONNECT Alarm will sound. Verify the charge status of the new Battery Pack. Turn the
unit's POWER switch to its "OFF" position. If required, place the unit on charge.
