2.3. WATER CONTACTS

The water contacts control the automatic activation
of the Dive Mode.
The water and data transfer contacts are located on
B
bottom of the case (Fig 2.3). When submerged the
water contacts are connected to the push buttons
(which are the other pole of the water contact)
by the conductivity of the water and an AC text
(Active Contacts, Fig. 2.4) will appear on display.
The AC text will be shown until the water contact
deactivates or the dive computer enters the Dive
Mode automatically.
Contamination or dirt on the water contacts or push
buttons may prevent their automatic operation. It
is therefore important that the water contacts and
push buttons are kept clean. If the water contacts of
the dive computer are active (AC-text remains on
display) or the Dive Mode activates on its own, the
reason for this is probably contamination or invisible
marine growth that may create an unwanted electric
current between the contacts. It is therefore important
that the instrument is carefully washed in fresh water
after the day's diving is completed. The contacts
can be cleaned with fresh water and, if necessary,
a mild detergent. Sometimes it might be necessary
to remove the instrument from the protective boot
for cleaning.
