NOTE

4.2. AC water contacts

The water and data transfer contact is located on the rear of the case. When submerged,
the water contact poles are connected by the conductivity of the water and the "AC" symbol
appears on the display. The AC text is shown until the water contact deactivates.
Contamination or dirt on the water contact may prevent this automatic activation. It is
therefore important that the water contact is kept clean. The contact can be cleaned with
fresh water and a soft brush, for example a tooth brush.
