Recharging the Batteries (Ni-MH Batteries Only)
Any battery charger capable of charging AAA Ni-MH batteries can be used to recharge the
SC-04’s Ni-MH batteries. RKI Instruments, Inc. recommends using one of the chargers
specified on pg.73.
WARNING:
To prevent ignition of a hazardous atmosphere, batteries must only be
charged in an area known to be nonhazardous.
1. Remove the batteries from the SC-04 as described in Step 1 - Step 5 on page 64.
2. Install the Ni-MH batteries in the charger. See the battery charger’s manual for charging
instructions.
