YSI 556 MPS Water Leakage Safety Information

The YSI 556 MPS has been tested and shown to comply with IP67 criterion,
i.e. submersion in 1 meter of water for 30 minutes with no leakage into
either the battery compartment or the main case. However, if the instrument
is submersed for periods of time in excess of 30 minutes, leakage may occur
with subsequent damage to the batteries, the rechargeable battery pack
circuitry, and/or the electronics in the main case.

If leakage into the battery compartment is observed when using alkaline C
cells, remove batteries, dispose of batteries properly, and dry the battery
compartment completely, ideally using compressed air. If corrosion is
present on the battery terminals, contact YSI Customer Service for
instructions. Refer to Appendix E Customer Service.

If leakage into the battery compartment is observed when using the YSI

rechargeable battery pack, remove the battery assembly and set aside to dry.
Return the battery pack to YSI Product Service for evaluation of possible
damage. Finally dry the battery compartment completely, ideally using
compressed air. If corrosion is present on the battery terminals, contact YSI
Customer Service for instructions. Refer to Appendix E Customer Service.

CAUTION: If water has contacted the rechargeable battery pack, do

not attempt to reuse it until it has been evaluated by YSI Product Service
(refer to Appendix E Customer Service). Failure to follow this precaution
can result in serious injury to the user.

If it is suspected that leakage into the main cavity of the case has occurred,
remove the batteries immediately and return the instrument to YSI Product
Service for damage assessment. Refer to Appendix E Customer Service.

CAUTION:

Under no circumstances should the user attempt to open

the main case.
