Should moisture appear inside the case, immediately have the instrument checked by your SUUNTO dealer or distributor.

Should you detect scratches, cracks or other such flaws on the display that may impair its durability, immediately have it replaced by your SUUNTO dealer or distributor.

Wash and rinse the unit in fresh water after every use.

Protect the unit from shock, extreme heat, direct sunlight, and chemical attack. The dive computer cannot withstand the impact of heavy objects like scuba cylinders, nor chemicals like gasoline, cleaning solvents, aerosol sprays, adhes- ive agents, paint, acetone, alcohol, etc. Chemical reactions with such agents will damage the seals, case and finish.

Store your dive computer in a dry place when you are not using it.

The dive computer will display 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.

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. Shorten the strap by cutting it if you do not expect to need the extra length.

MAINTENANCE

The instrument should be soaked, thoroughly rinsed with fresh water, then 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. DO NOT use the dive computer if you detect any moisture or water inside. Contact an au- thorized Suunto dealer for battery replacement or other service.
