Snorkeling/Scuba Diving Precautions
• Make sure that you have received proper diving training before using
this watch underwater.
• Always use the "buddy system" when diving. Never dive alone.
• Note that this watch is NOT a diving computer, and is not capable of
making decompression calculations.
• The depth meter function built into this watch should only be used as
a "back-up" to your standard depth gauge.
• Note that this watch cannot be used in helium atmospheres.
• Though the function of this watch is not affected by magnetism, long
use near a source of magnetism can case the watch itself to become
magnetized. A magnetized watch can interfere with the precision of
readings produced by an underwater compass. To avoid such
problems, keep the watch away from your compass when taking
readings.
Before Diving
• Before beginning each dive, check to make sure that the BATT (and/
or RECOVER) message (which indicates that battery power is weak)
and/or ERR message (which indicates sensor malfunction) are not on
the display. If either message is on the display, contact an authorized
CASIO Dealer/Distributor or authorized CASIO Service Point to have
the battery replaced or to have the watch repaired.
• Make sure that the current time setting of the watch is correct.
• Check the glass, case, and band for cracks or chips.
• Make sure that the band is fastened securely around your wrist.
While Diving
• Check to make sure that the timer and depth gauge are operating
properly.
• Warning indicators flashing on the display indicate the possibility of
a data error. For details, see "Warning Indicators".
• Take care when diving near rocks or coral to avoid scratching or
damaging the watch.
After Diving
• To avoid corrosion, rinse your watch thoroughly with fresh water to
remove salt water, dirt, etc. When possible, soak the watch in fresh
water overnight to make sure that all salt is removed.
• When using a metal band, occasionally clean the gaps in the band
using a soft toothbrush and soapy water. Failure to keep a metal
band clean can result in corrosion of the watch, soiling of clothing, or
irritation of sensitive skin.
CASIO COMPUTER CO., LTD. assumes no responsibility for any
loss, or any claims by third parties that may arise through the use of
this watch.
• Button operations are indicated using the
letters shown in the illustration.
• Each section of this manual provides you
with the information you need to perform
operations in each mode. Further details
and technical information can be found in
the "REFERENCE" section.
