or greater). This prevents unintentional exiting of the Diving Mode while diving.

• After completing one dive, temporarily enter the Timekeeping Mode and then re-enter the Diving Mode
before the next dive.
Auto Timekeeping Mode Return
Before diving
• If you leave the watch in the Diving Mode for about 30 minutes while on the water surface (Depth: 0
meters), it will automatically return to the Timekeeping Mode.
• When on the water surface for a long period in order to move to another location or for some other
reason, make sure you confi
rm that the watch is in the Diving Mode before diving again.
During a Dive
• If a dive time exceeds six hours, the watch will automatically switch to the Timekeeping Mode and
record a dive time of 6:00 up to that point.
After diving
• If more than 10 minutes of surface time elapse at a depth of 1.4 meters or less, the watch will enter the
Timekeeping Mode automatically.
E-38
Entering the successive dive wait state starts measurement of the elapsed surface time.
• If the surface time exceeds 10 minutes, the watch will automatically enter the Timekeeping Mode and
stop log memory recording.
• Even though the watch enters the Timekeeping Mode, elapsed surface time measurement continues.
When the watch detects submersion to a depth greater than 1.5 meters, it will exit the successive
dive wait state and resume dive time measurement and log memory recording.
• The watch will reset the surface time to zero when it detects resumption of a dive with a depth of 1.5
meters or greater.
Viewing Log Records
While in the successive dive wait state or pre-dive wait state*, press
A
.
• This will display the diving log data for your previous dive for about

Water Depth Auto 0-meter Reset
Enter the Diving Mode before diving. Ambient pressure at the time the watch enters the Diving Mode is set
as the 0-meter depth (page E-41). After that depth, water temperature, and dive time measurements are
performed automatically.
Auto Measurement and Log Data Memory During a Dive
While in the Diving Mode, the watch will detect when water depth is 1.5 meters or greater at the start of a
dive, and automatically start measuring the elapsed dive time. The dive start time is also recorded in
watch memory.
To display water temperature
• Pressing
A
while under water displays the current water temperature for about three seconds.
To take a direction reading
• While in the Diving Mode, pressing
D
will display your bearing for about 20 seconds while measuring
water depth.

Using the Diving Functions
Entering the Diving Mode and starting a dive causes the watch to create a log record, and start measuring
and recording dive time, water depth, and water temperature automatically. After a dive is complete, the
watch also displays the surface time.
Important!
• Charge the battery to at least Level 2 before using it for diving.
• Before diving, enter the Diving Mode while on a boat or in another location outside the water.
• Even if a sensor reading operation results in an error, the current time and dive time will continue to be
displayed.
• Low battery power will cause sensor operations to be disabled, but the current time and dive time will
continue to be displayed.
Note
• For details about the type of data that is measured and measuring ranges, see “Diving Function
Measurement Data and Ranges” (page E-43).
Before Diving
While on a boat or in any other location outside the water, hold down
C
for about three seconds until
DIVE
appears on the display.
• This enters the Diving Mode. Refer to page E-25 for information about navigating between modes.
