8. CARE AND MAINTENANCE
The Suunto Cobra2 dive computer is a sophisticated precision instrument. Though designed
to withstand the rigors of scuba diving, you must handle your Suunto Cobra2 with care,
and follow the advice below on how to maximize its service life.
8.1. Water contacts and buttons
Contamination or dirt on the water contacts/connector or buttons may prevent the automatic
activation of the DIVE mode and cause problems during data transfer. Therefore, it is
important that the water contacts and push buttons are kept clean. If the water contacts
of the instrument are active (AC-text remains on the display) or the DIVE mode activates
on its own, the reason is probably contamination or invisible marine growth that may create
an unwanted electric current between the contacts. It is important that the dive computer
is carefully washed in fresh water after the day's diving is completed. The contacts can
be cleaned with fresh water and, if necessary, a mild detergent and a soft brush.
8.2. Care of your dive computer
•
NEVER try to open the case of the dive computer
•
Have your dive computer serviced every two years or after 200 dives (whichever comes
first) by an authorized Suunto representative. This service will include a general
operational check, replacement of the battery, and a water resistance check. The
service requires special tools and training, so do not attempt to carry out any service
that you are not competent to perform
•
If moisture appears inside the case, have the instrument checked immediately by your
Suunto representative
•
If you detect scratches, cracks or other such flaws on the display that may impair its
durability, have it replaced immediately by your Suunto representative
•
Check the strap and the buckle for flaws. If needed, have them replaced by your Suunto
representative
•
Wash and rinse the unit in fresh water after every use
•
Protect the unit from shock, extreme heat, direct sunlight, and chemical corrosion. The
dive computer cannot withstand the impact of heavy objects like scuba cylinders, nor
chemicals like gasoline, cleaning solvents, aerosol sprays, adhesive agents, paint,
acetone, alcohol etc. Chemical reactions with such agents will damage seals, the case,
and the finish
•
Store your dive computer in a dry place when you are not using it
•
The dive computer displays a battery symbol as a warning when the power gets too
low. When this happens, the instrument should not be used until the battery has been
replaced. Also refer to
Section 5.9. Activation and pre-checks
•
Do not fasten the strap of your dive computer too tightly. You should be able to insert
your finger between the strap and your wrist
8.3. Maintenance
If left without care for an extended period, a thin film, often invisible to the naked eye, will
cover the unit. Much like the build-up on the glass of an aquarium, this film is the result of
organic contaminants found in both salt and fresh water. Suntan oil, silicone spray and
grease will speed up this process. As a result of this build-up, moisture will be trapped
next to the water contacts and will prevent your Suunto Cobra2 from operating properly.
The water contacts can be cleaned with a small brush (e.g. toothbrush).
IMPORTANT: Your Suunto Cobra2 should be soaked, then thoroughly rinsed with fresh
water and dried with a soft towel after each dive. Make sure that all salt crystals and sand
particles have been flushed out. Check the display for possible moisture or water, and do
not use the Suunto Cobra2 if you detect any moisture or water inside.
