Register ring (if any)
Use the register ring to measure elapsed time.
<Using the register ring>
Before diving, rotate the register ring to line
up the mark with the minute hand. Elapsed
time is then indicated by the position of the
minute hand on the register ring.
Example: in the diagram at left the minute hand is
10 minutes past the mark, indicating that 10
minutes have elapsed.
– NOTE –
The register ring may only be turned counter
clockwise (this helps prevent unwanted move-
ment). Do not attempt to force it to turn clockwise.
Elapsed time
is 10 minutes
