1. Explanation of Display During Water Depth Measurement
The display during diving differs between the AIR setting (air diving) and NITROX setting
(NITROX diving). Even in the case of performing scuba diving, the watch displays the skin
diving display until 3 minutes or more have elapsed continuously at a depth of 1 m (4 ft) or
more.

Decompression stop instructions (depth, time)
• If diving is continued beyond the no-decompression limit time, an alarm sounds and decompression
stop instructions (STOP) are displayed on the display indicating that decompression diving has
occurred.
• Pressing the lower right button (A) once during scuba diving calls up the current time, maximum
depth, water temperature and body nitrogen level graph (the body nitrogen level graph is not
displayed during decompression diving).
