Warning!
Note the following important points concerning Identification Mode data
stored in the memory of this watch.
• The SCUBA diver certificate number and passport number stored
in the memory of this watch can be misused whenever the watch
is in the hands of another party. To protect against the misuse of
the SCUBA diver certificate number and passport number, input
them in coded form that cannot be understood by others.
• Make sure you correctly input your blood type data. Once you
input your blood type, take care that another person does not
wear the watch. Otherwise, emergency medical personnel may
assume that your blood type applies to the person who is
wearing the watch.
• The default blood type screen setting when you first purchase the
watch or after you re-charge the battery after power drops to
Level 5 is “
A” for the blood type and “Rh *” for the Rh factor.
To avoid problems caused by display of the wrong blood type, we
recommend that you input your correct blood type data as soon
as possible after purchasing the watch and whenever you re-
charge the battery after power drops to Level 5.

Read This Before You Set the Time and Date!

and date you are setting), before you set the date and time. You can use
any one of the 10 snorkeling and scuba diving sites pre-programmed in
watch memory as the Home Site, or you can create your own.
Important!
If the site you want to use as your Home Site is not in the above list, use
the procedure under “Changing Site Data” to edit the pre-programmed
site data.
