2-5.Units of Measurement
・
You can change the units of water depth and temperature by the switches of this product
①
Changing water depth units from meter to feet.
The display will show 0-328ft(0-99.9m).
②
Changing temperature units from Centigrade to fahrenheit.
The display will show 23
～
104
°
F(-5
～
+40
℃
).
These numerals are based on meter and
℃
and calculated to the new units.
・
Operating method: In dive set mode, hold down switches A + C for 6 or more seconds. When
you do this, the buzzer will sound to tell you that the unit system has changed.
2-6. Caution points for User
2-6-1. Caution related product handling
・
Before using this product, read the manual and be sure you understand it thoroughly.
・
Do not store or leave this product in a hot or moist place. Doing so could damage its
performance. The pressure sensor is particularly susceptible and could give incorrect
displays of altitude rank and water depth. If the computer becomes overheated, put it in
water to cool it down.
・
Leaving the computer in a hot place could cause the liquid crystal display to turn black, but
it will return to normal when it cools down.
This situation should still be avoided since it can shorten the ilfe of the panel.
・
You should be aware that the computer may give an incorrect altitude rank because of
weather-related changes in air pressure.
・
Do not subject the computer to pressure chamber tests such as with air or gas. This could
affect sensor precision.
・
Never take apart the product. This will void the guarantee.
2-6-2. Battery
・
When the battery mark is illuminated or blinking, record the data in your log and promptly
change the battery.
・
A low battery left for a long period of time could lead to leakage, so change promptly.
・
Have the battery changed by manufacturer, which has technicians trained to do this.
・
When changing the battery, be careful of scratches on the back cover’s O-ring and make sure
that no foreign matter sticks to it. If you discover scratches or other problems with the
O-ring, replace the O-ring with a new one.
2-6-3. Diving
・
Always check the battery’s power when you go diving. If the battery mark is illuminated or
flashing, it will not change to Dive mode.
・
Before you dive, always check the FO
2
and FHe in dive set mode. You will not be able to set
the FO
2
and FHe when you are in the water.
・
You should dive so that you have plenty of margins to stay on no-decompression diving.
Always make a safety stop at three to six meters if you dive to 15 meters or deeper. We also
recommend that if the computer tells you to make a decompression stop, you should stop for
longer then the time directed. In this case, you should check the air’s residual pressure.
・
This product does not manage your supply of air. You should therefore be aware of your own
air supply.
・
You should use backup instruments (such as another dive computer, a depth meter, diver’s
watch, etc.) in addition to this product.
・
After your dive you should calculate decompression based on the altitude rank. Sudden
changes in altitude rank are very dangerous. You must therefore not move anyplace that
would cause significant changes in altitude rank after your dive.
・
This dive computer has a lockout function that will not let it work in a dive for 48 hours if
you dive in a dangerous way. This lockout function can be forcibly released for factory in
process inspections. Even if the lockout is accidentally released, you should still refrain from
diving for 48 hours.
2-6-4. User care and maintenance
・
After diving, clean your dive computer in pure water. Do not, however, leave the unit in the
water for long periods, since this can shorten battery life. Wipe away any soiling or mineral
deposits from the water 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 change its quality. Use proper care, because this can cause 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 the direct sun 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, leave it in water that is
close to ordinary temperature until the product returns to normal temperature. Exposure to
extreme heat or cold can not only cause the computer to measure water depth, altitude rank
and water temperature less precisely, but could also cause it to be damaged, so avoid these
conditions.
・
If you believe the watch has sustained damage, do not use it but rather bring it promptly to
the manufacturer for repair.
2-7. Troubleshooting
The following list will help you make the proper diagnosis when you believe the product is
working abnormally. Consult with the manufacturer if any problems occur that are not on this
list.
