NOTE: The battery pack is pre-installed in the ProDSS instrument.
WARNING: Do not charge or handle a battery pack that is hot to the touch. Failure to follow the safety warnings
and precautions can result in personal injury and/or instrument damage not covered under
warranty. Read

1. Remove the battery pack cover by unscrewing (counter-clockwise) the four screws with a flat or Phillips head
screwdriver ( Figure 2 on page 7 ).
NOTE: The retaining screws are captured into the battery pack cover and are not removable.
2. If replacing an existing battery pack, remove the Li-Ion battery pack and battery pack gasket/cradle. With two
fingers, grasp the battery pack connector and pull the connector straight up to disconnect and remove.
NOTE: Properly dispose of the old battery pack ( Battery Disposal on page 80 ).
NOTE: A new gasket/cradle is included with a new battery pack to prevent water leaking into the instrument case.
When replacing the battery pack, use the new battery pack gasket/cradle supplied with the replacement
battery pack.
3. Inspect the replacement battery pack and battery pack gasket/cradle for damage. Contact YSI customer service
if the new battery pack and/or replacement gasket/cradle is damaged.
4. Correctly align and seat the battery pack gasket/cradle and battery pack into the instrument.
5. Align the battery pack connector wire terminals with the three instrument pins, then connect the battery pack to
the instrument.
NOTICE: Make sure that the three wire terminal connectors and three instrument pins are correctly aligned
before connecting the battery pack connector. Incorrect installation can damage the battery pack
connectors or instrument pins.
6. Install the battery pack cover, then tighten the cover screws. Make sure that the cover sealing surface is correctly
aligned and free of any contamination or damage.
NOTICE: Overtightening the cover screws can damage the battery cover.
