D. For safe usage
[Make sure you read this caution]=
A CAUTION:
1. Items to check for safe usage
a. The depth display of this watch is up to 80m(260ft).
Although this watch has water resistance up to 200m(656ft), the depth display only
goes up to 80m(260ft). For safe diving we recommend that you stay shallower than 30
meters( 100ft) [sports diving].
We recommend that yqu stay within these
limitsof sports diving,(no decompression)
m^-
0m
30m
<The limit of the
depth displays
<The limit of water
200m resistance. >

b. The water depth meter in this watch is set according to the sea water standard
(1.025 gravity).
In case you use the watch infresh water, i.e. lake water etc., you need to make a con
version.
[Example]
When the watch is 80m(260ft) deep, in the case of sea water itdisplays 80m(260ft), but
when in fresh water, it displays 78m(253ft); Shallower than what it really is.
(Caution)

c. Avoid descending too rapidly.
Inorderto get an accurate depth readings, slow down
the descent, or stop.
d. Avoid ascending too rapidly.
Ifyou ascend at a speed greater than 1 5m(5ft) per 5secs
(D201/D207). /0.9m(3ft) per 6 sees (D202/D208).
18m(60ft) per minute (D201/D207)/9m(30ft) per minute
(D202/D208) according to the U.S. navy diving manual),
then the ascending speed warning function willoperate.
The dot display changes to "SLOW display and an alarm
will sound.
Please maintain a safe ascending speed.
Slow down your ascent or stop in order to get an accurate
depth reading.
As rapid ascending is hazardous to the human body,
sometimes causing the bends, always avoid it
*The new regulation of the U.S. Navy diving manual is executed on t993, changing the
Surface Speed Warning at the rate of 9m/min. from 18m/min.

e. Do not use the watch in places where it is exposed to large changes of air
pressure or temperature. ~n . •
The watch willautomatically check for unusual air pressure, while in various normal
modes (time and calendar mode / surface mode / log,mode / alarm mode).If any .
abnormality is detected, the dot display will alternate between dot display and '•
"ERR"display. When this happens, the v/ater depth cannot be measured. Ifthe
"ERR" display disappears, the watch canbeused normally. Or,
ftWhen boarding a plane. . )' —i. ; •
When exposed to sudden pressure phange (pressurization) as:in the inside of an
aeroplane, ifthe water sensor is touched with a finger ormoistened, the watch may
change to dive mode. Ifit changes to dive mode, dry the water sensor, and cancel
