correct.
The summer time setting (standard time/
summer time) is wrong.

Diving Function
Q1
I can’t enter the Dive Mode.
The watch does not enter the Dive Mode while
its charge is low or dead. Charge the watch
before using it for diving.
Q2
The watch enters the Timekeeping
Mode when it switches from dive time
measurement to surface interval
measurement.
If the charge becomes low while in the Dive
Mode, the watch is not able to perform surface
interval measurement. Charge the watch
before using it for diving.
Q3
Measurement is in progress when I
switch from the Timekeeping Mode
to the Dive Mode.
This happens when a previous measurement
is being continued. Enter the Dive Mode and
reset measurement.
l
Tide Level
Q1
There are errors in the tide
information.
Since the high tide and low tide times and tide
levels of the Tide Graph are calculated based
on past data, the calculated data may be
different from actual tide information.
Also note that the degree of the error can be
affected by terrain, weather, and other
conditions. Use the tide information of this
watch for reference only.
Be sure to check accurate tide forecast
information issued by various organizations,
and do not use the tide information of this
watch to determine tide levels used for
navigation or any other purpose where there
is the risk of danger.
