Battery Replacement; Hot Swap - Oceanic Dive Computer Pro Plus 2 Operating Manual

The Battery Compartment should only be opened in a dry
and clean environment with extreme care taken to prevent
the entrance of moisture or dust.
As an additional precautionary measure to prevent formation
of moisture in the Battery Compartment, it is recommended
that the Battery be changed in an environment equivalent to
the local outdoor temperature and humidity (e.g., do not
change the Battery in an air conditioned environment then
take it outside during a hot sunny day).
Inspect the Buttons, Lens, and Housing to ensure they are not
cracked or damaged. If there is any sign of moisture in the
module, DO NOT use the Pro Plus 2 until it receives proper
service by an Authorized Oceanic Dealer, or the Oceanic
factory.
If the new Battery can be inserted within 8 seconds after the
old one is removed (Hot Swap), settings and nitrogen and
oxygen calculations for repetitive dives will be retained.
