Note: Specifications are additi/- one least significant digit due to
rounding. Specifications are subject to change without notice.
ENHANCEMENTS: The COMMANDER is capable of
having its’ capabilities enhanced. It can be upgraded
to a one blend Nitrox ( can be done by an Authorized
Dealer) or two blend Nitrox computer or a One or Two
blend Nitrox/PO
2
computer. The Dive Profile Storage
memory capacity can be upgraded from a base of 135
hours to 550 hours.
The COMMANDER must be
returned to the factory for all upgrades except to
that of a one blend Nitrox.
CLEANING THE COMMANDER: Clean the unit only
with fresh water after each use. Towel dry the unit,
never use air pressure to dry the unit. This could
damage the unit and will void the warranty. Do not use
chemicals to clean the case or lens as this may
damage the unit, or permanently fog the lens.
CHANGING BATTERY: The batteries should be
changed when the ‘BATT’ legend is seen or battery
voltage reaches 2.1 volts as can be seen on the
Information Display. The unit will operate until the
battery voltage drops below 1.6 volts. Only use fresh,
name brand N-Cell size Alkaline batteries for
maximum battery life. At this time,
Eveready
Energizer Alkaline is recommended. Care should be
taken not to activate the TACLITE™ during battery
replacement. Be sure to confirm that the batteries are
REALLY new and have not been sitting on a shelf
losing life. Cold temperatures tend to shorten
apparent battery life. Change batteries every two
years regardless of battery condition.
CAUTION!!! COMPLETE LOSS OF BATTERY
POWER MAY CAUSE ALL PREVIOUS DIVE
NITROGEN LOADING TO BE LOST. THIS MAY
AFFECT NITROGEN CALCULATIONS ON NEAR-
FUTURE DIVES. AFTER A BATTERY CHANGE,
CONFIRM THAT NO-DECOMPRESSION TIME
DATA IS REASONABLE DURING PRE-DIVE
PREDICTION MODE. DIVE-OF-DAY NUMBER
GOING TO ZERO IMMEDIATELY AFTER
CHANGING BATTERIES IS ANOTHER INDICATION
OF A LOSS OF NITROGEN LOADING.
