BATTERY INSTRUCTIONS
Battery Charging
See separate operating instructions provided with the MicroAire UL Classied Battery Charger (REF 7500-700).
Battery Installation
The REF 7800 Battery Sternum Saw handpiece must have a fully charged MicroAire battery pack (REF 6640-710, REF
7505-710 or Aseptic Battery) installed before use. To attach the battery to the handpiece, place the battery under the
base of the instrument with the longer side facing the rear of the instrument. Firmly push the battery into the base of
the handpiece until the battery latch clicks into place.
Aseptic Battery
The REF 7800 Battery Sternum Saw is designed to operate using the MicroAire Aseptic Battery. The Aseptic Battery
uses a non-sterile battery pack REF 7500-620 that is placed in a sterilized System housing REF 7500-615 with
locking door, and removes the need to steam sterilize battery packs. See separate instructions provided with
the REF 7500-6XX Aseptic Battery System.
CAUTION: Leaving a battery pack attached to a handpiece when not in use may accelerate battery drain.
