You should dive so that you have plenty of margins to stay within no-
decompression diving limit. Always make a safety stop at three to six meters if
you dived to 10 meters or deeper. We also recommend that if the computer tells
you to make a decompression stop, you should stop longer then the time directed.
In this case, you should check the residual pressure in your tank.
It is recommended that you should use backup instruments (such as another dive
computer, a depth gauge, diver’s watch, etc.) in addition to this product.
After your dive you, should calculate decompression based on the altitude of the
entry point. A sudden change in altitude is very dangerous. You must therefore
not move anywhere that would cause a significant change in altitude immediately
after.
This dive computer has a lockout function that will not let it work for diving for
48 hours if you dive in a dangerous way.
IV. MAINTENANCE AND STORAGE
After diving, clean your dive computer in clean, fresh water. Do not, however,
leave the unit in water, since this can shorten the battery life. Dry and wipe away
any soiling or mineral deposits with a soft cloth.
Solvents (such as alcohol and gasoline), sprays (such as cosmetics cleaning
liquids), adhesive and paints will stick to the computer, while alkali, aromatic
hydrocarbons, hydrocarbon halide etc. can damage the casing and this can lead
the dive computer to lose its waterproofing.
Keep the dive computer in a cool, dry place. Dry it well after diving and do not
keep it with wet items. Do not leave it in direct sun light or on a car dashboard,
which could cause the unit to overheat. Also avoid putting the dive computer
in extremely cold places. If for some reason the dive computer is exposed to hot
or cold temperatures, put it in water that is close to ambient temperature until
the product returns to normal. Exposure to extreme heat or cold can not only
cause the computer to measure water depth, altitude and water temperature less
precisely, but could also cause damage.
If you believe the computer has sustained damage, do not use it! Bring it
promptly to your closet IST authorised dealer for inspecition and repair.
Avoid impact, static electricity, extreme temperature and high humidity.
