Depth Sensor
The built-in depth sensor of the Spyder is a sophisticated precision instru-
ment. The depth sensor cover may be opened only by an authorized SUUNTO
dealer or distributor. NEVER try to open the cover yourself. Keep the area
around the depth sensor clear from dirt, sand, dust or other substances. Rinse the
device thoroughly with fresh water and dry it with a soft towel. Never use
pins, needles or other objects to clean the depth sensor.
Water Contact
The water contact controls the automatic activation of the Dive Mode, as well as
the automatic return from the Dive Mode to the Time Mode. Con-
tamination or dirt on the water contact may prevent these automatic opera-
tions. It is, therefore, important that the water contact is kept clean. The
contact can be cleaned with fresh water and a soft pencil eraser.
NOTE: Water or moisture build-up around the water contact may cause the contact
to activate automatically. This can happen, e.g., when washing your hands or
sweating. If the water contact activates in the Time Mode, an ACW text will appear
on display (see Fig. 4.2. b), and it will be shown until the water contact deactivates,
or the Spyder enters the Dive Mode automatically. To save the battery power, you
should deactivate the water contact by cleaning it and/or drying it with a soft towel.
Exposing the Spyder to great temperature changes may cause the Dive Mode to
activate automatically. The Spyder will return to the normal display (timekeeping)
10 minutes after the water contact has dried. To save the battery power and also to
enable the use of the timekeeping display, it is recommended to return to the nor-
mal display by using the push buttons.
