5.2 Maintenance
The depth accuracy should be verifi ed
every two years, that can be done by
authorized SCUBAPRO dealer. Besides
this, Square is virtually maintenance free.
All you need to do is rinse it carefully with
fresh water after each dive and change the
battery when needed. To avoid possible
problems with your Square, the following
recommendations will help assure years of
trouble free service:
- avoid dropping or jarring your Square
- do not expose Square to intense, direct
sunlight
- do not store Square in a sealed container,
always ensure free ventilation
If there are problems with the water
contact, use soapy water to clean Square
and dry it thoroughly. Do not use silicone
grease on the water contacts!
- Do not clean Square with liquids
containing solvents.
- Check the battery capacity before each
dive.
- If the battery warning appears, replace
the battery.
- If any error message appears on the
display, take Square back to an authorized
SCUBAPRO UWATEC dealer.
