<Repetitive Diving>
Repetitive diving refers to diving that is repeated while there is still residual nitrogen in the body
from the previous dive. The number of the next dive for repetitive diving is displayed on the
second display of the dive plan mode.
<Decompression Diving>
This refers to diving beyond the no-decompression limit time. Decompression diving is
extremely dangerous since nitrogen accumulates in the body beyond allowable levels. Never
dive in this manner.
<Decompression Stop>
This refers to a stop that must be made to ensure the necessary decompression in the case of
having performed decompression diving. It is necessary to make a decompression stop at a
predetermined depth (decompression stop instructed depth) and predetermined time
(decompression stop instructed time) when ascending.
<Safety Stop>
Safety stop refers to a temporary stop made during ascending for safety reasons in order to
promote expulsion of nitrogen in the body, and is performed even if the no-decompression limit
time has not been exceeded. In the case of having dove to a depth of 18 m (60 ft) or more, a
safety stop should always be made at 5 m (15 ft) of depth to ensure safety.
<Total Ascent Time>
This refers to the minimum time required to ascend to the surface from the current depth in the
case of ascending at the rate of 18 m (60 ft)/min or less while making a decompression stop in
accordance with the decompression stop instructions during decompression diving.
<Body Nitrogen Level>
This refers to the amount of nitrogen dissolved in the body as a result of diving. This watch
displays a general indicator of the amount of nitrogen dissolved in the body in the form of a bar
graph. The higher the level of the black portion of the graph, the greater the body nitrogen level.
<Total number of Dives (Log Count)>
This indicates the total number of dives for scuba diving.
* Arbitrarily resetting the number of past dives with the “CAPgm” software provided before using the watch
for diving enables this to display the total number of scuba dives made throughout your life.
<Dive Date>
This is the date (year, month and date) on which a dive was made.
<Dive Number>
This is the number of dives made in one day. A maximum of 15 dives are counted per day for
skin diving and scuba diving, respectively.
* This indicates the number of a dive for a particular dive date.
The counter is reset to 1 when the day changes.
<Surface Interval Time (S.I. Time)>
This refers to the elapsed time following completion of scuba diving (surface interval time (S.I.
Time)). This watch measures surface interval time up to a maximum of 24 hours.
* S.I. Time as referred to in the scuba diving log mode represents the elapsed time from completion of the
dive of the previous log until the start of the dive of the current log.
