CARE AND MAINTENANCE

The DataMax Pro is a sensitive electronic instrument.  Although it has

been designed to survive the rigors of diving, it still must be handled carefully
to protect from shock, excessive heat, chemical attack, and tampering.

 The DataMax Pro is protected by an outer rubber boot that, along with

the hose, can be cleaned and protected periodically by application of a silicone
milk available in dive stores.  The internal housing is made of an impact
resistant resin that is extremely shock resistant but can be susceptible to
chemical attack and scratches.  If the gauge face becomes scratched Oceanic
can replace it, although small scratches will naturally disappear underwater.

CAUTION:  Never spray aerosols of any kind on, or near, the
DataMax Pro.  The propellants may chemically attack the
plastic.

BEFORE THE DIVE

After attaching the DataMax Pro, be careful not to leave it lying on a boat

deck where it might be damaged.  Many dive computers (and dive trips) are
ruined by encounters between carelessly tossed computers and weight belts
or tanks.  If the DataMax Pro is attached to a tank in a rack, tuck the com-
puter into a BC pocket, or between the BC waistband and the bladder.  Keep
it off the deck and protected from undue shock.  Better yet, attach a
