Introduction

If you follow the right rules of scuba diving and skin diving, you can enjoy safe water sports. But on the other hand, there is an element of danger from the bends and other possible accidents. So after receiving proper training, please check for safety and enjoy your diving.

When you use this product, please understand the instructions and warnings well, so that you may use it properly.

In a case where this product is used in a way that is not mentioned in the USER’S manual, the watch might not function properly.

Furthermore all repairs including battery replacement should be carried out by a Citizen Service Centre. Please arrange for a Citizen Service Centre to look after your watch through the shop from which it was purchased.

A. Special functions of this watch

This is a full-scale divers watch with digital display and an electronic depth gauge.

1)This watch measures and displays depth as soon as you start diving, due to the water sensor

2)This watch measures the water temperature while diving; and when not diving, the air temperature.

3)While you are diving, various log data is recorded.

4)After completing a dive, by using a communication unit, you can transfer data to a personal computer and also confirm the data with a personal computer

Compatible computers: IBM PC / AT or any other compatible computer with keyboard and monitor. (There are some computers that are not compatible.) For more details, please read the “Communications AQUALAND GRAPH USER’S MANUAL”.

5)The elapsed time after a valid dive is completed (maximum of 24 hours) is measured automatically. This watch can be used as a safety guideline for resting time on the surface. [surface mode]

6)To ensure safe diving, various warning functions are included.

B. For safe diving

Basic knowledge and techniques are required to dive safely so please take the necessary training to acquire them.

In order to use this watch safely, C. [Usage points that should be avoided while diving] and D. [for safe usage] need to be understood sufficiently when using this watch for diving.

C.Usage points that should be avoided while diving [make sure you read this warning]

When you use this watch for diving, please heed the following points. [Do not use under these conditions.]

WARNING:

1.Do not use under these conditions:

a.If you have not taken a course on safe diving, please do not use the watch.

b.Please do not use the watch outside the temperature limits. The temperature limits for this watch are 100C ~ 400C (100F ~ 1040F). If you use the watch outside of this range, it will not display accurate depth.

c.Never use the watch while diving with helium gas [saturated diving]. If you use the watch with helium gas, it is likely to cause problems, or failure.

d.Do not use the watch for determining your actions in dangerous situations. This watch is not designed as equipment for the prevention of emergencies or accidents.

e.Do not use this watch as a substitute for pressure equipment in applications other than diving or instead of a buddy system. This watch is not a gauge or meter which is authorised by any public organisation, it should be used as a guide line for auxiliary equipment.

f.Do not use this watch at altitudes over 4000m (13,120 ft) since water depth cannot be measured at higher altitudes.

g.Do not use the watch outside of the water depth measurement range.

h.In case the safe diving warning function activates, immediately check the watch, and stop using it. Look up “various warning

functions” to find out how to deal with each one.

(Before Diving)

1)When the water sensor check warning function operates – the dot display alternates between dot display and “CHEK.” (D201/D207)/ “ERR”(D202/D208) display as a warning.

2)When the battery warning function operates – the dot display alternates between dot display and “BAT.” (D201/D207)/“BT” (D202/D208) display as a warning.

3)When the unusual air pressure error warning function operates – the dot display alternates between dot display and “ERR” display as a warning.

4)When the watch stops or something goes wrong with it, please do not use it.

5)When the water depth meter display on the watch shows a big difference with other water depth meters, please refrain from using the watch.

(While Diving)

1)When the depth chart error warning function operates – the dot display alternates between dot display and “ERR” display as a warning.

2)When the battery warning function operates – the dot display alternates between dot display and “BAT.” (D201/D207)/“BT” (D202/D208) display, as a warning. Once the battery warning display appears, please realise we can”t guarantee the accuracy of the depth measurement.

3)When the watch stops or something goes wrong with it, please do not use it.

4)When the water depth meter has a big difference with other water depth meters, please do not use the watch.

D. For safe usage

[Make sure you read this caution]

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 80m (260ft), for safe diving we recommend that you stay shallower than 30 metres (100ft) [sports diving].

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 in fresh water, i.e., you need to make a conversion.

[Example]

When the watch is 80m (260ft) deep, in the case of sea water it displays 80m (260ft), but when in fresh water, it displays 78m (253ft); shallower than what it really is.

c.Avoid descending too rapidly.

In order to get an accurate depth reading, slow down the descent, or stop

d.Avoid ascending too rapidly.

If you ascend at a speed greater than 1.5m (5ft) per 5 secs (D201/D207). /0.9m (3ft) per 6 secs (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 will operate. 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 in 1993, 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.

The watch will automatically 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 water depth cannot be measured. If the “ERR” display disappears, the watch can be used normally.

When boarding a plane

When exposed to sudden pressure change (pressurisation) as in the inside of an aeroplane, if applicable, if the water sensor is touched with a finger or moistened, the watch may change to dive mode. If it changes to dive mode, dry the water sensor, and cancel dive mode by holding down button M for more than 2 seconds.

f.We recommend that you change the battery as early as possible.

The life of the battery in this watch is about 3 years after a new battery is installed. (Please look up S. [Battery] for the conditions of usage). However, the life of the battery changes a lot depending on the frequency of use of various functions. In order to enjoy safe diving, we recommend that you change the battery ahead of time.
