Operating Temperature
The Monitor 3 Air operates normally between 12

C to 50

C). You may notice the liquid crystal display
(LCD) becoming sluggish at extremely low temperatures.
This is normal and will not affect the computer’s accuracy.
It is possible to damage the electronics if left exposed to
direct sunlight or in a hot, confined space (like a car
trunk). After the dive, cover the computer and keep it out of
the sun. If inadvertently left in direct view of the sun, the
LCD may become totally black. If this occurs, immediately
immerse the Monitor 3 Air in water. The display should
recover its normal appearance after a few minutes. Damage
from extreme heat or cold is not covered under the two-
year limited warranty.
Replacing the Battery
The Monitor 3 Air's battery is not user-replaceable. It must
be returned to the factory for replacement. Factory service
was discontinued in 1997. Please contact the original
manufacturer, Uwatec, at 800-467-2822.
