Read this manual carefully and pay attention to all dangers, warnings, and cautions. Make sure you fully understand the use, displays and limitations of the watch. Neglecting to understand and follow the instruction manual may cause errors to be made during diving that may lead to serious injury or death.


Diving is a potentially dangerous sport. When using this watch for diving, make sure to have a correct understanding of this watch as described in this manual and strictly adhere to the procedures for its operation.
The watch may not function properly if handled in a manner not described in this manual.

GeneralCautions Regarding Diving
In the case of using this watch for diving, always make sure to receive the proper scuba diving training from a certified instructor so that you have the necessary experience and skills required for safe diving. In addition, make sure that you have completely mastered the handling and operation of this watch.
Even though you may only be engaged in recreational diving, any type of diving can be potentially dangerous. Attempting to engage in diving with improper or inadequate training can result in a fatal or serious accident.
Never attempt NITROX diving unless you have received special training for NITROX diving.
Although this watch is also compatible with NITROX diving, NITROX diving presents serious or potentially fatal risks unlike ordinary diving using compressed air.
Each diver should be responsible for formulating and executing a diving plan to ensure safety that matches his or her own abilities.
The dive computer function of this watch is not designed to completely prevent the occurrence of decompression sickness. In addition, it is unable to monitor differences in the physiological functions of individual divers or differences in physical condition on a particular day. Since physical condition has a considerable effect on the occurrence of decompression sickness, the degree of the risk of decompression sickness varies depending on the physical condition of the diver on that day. It is therefore recommended to avoid diving when physical condition is poor, such as in the case of illness, fatigue, lack of sleep or hangover. Cautions Regarding Use of this Watch
Cautions Regarding Use of this Watch
Do not use this watch during decompression diving, especially during NITROX diving.
Although this watch will provide data on decompression diving in an emergency, using this watch for decompression diving entails risks. Since decompression diving during NITROX diving in particular is very dangerous, never use this watch under these conditions. Decompression diving during NITROX diving can lead to an accident causing death or serious injury. (The DCIEM algorithm generates a particularly hard error in the case of decompression diving during NITROX diving.)
Never loan or share the watch with another person when resting on the surface (while the watch is operating in the surface mode). In addition, do not use the data displayed by the watch as the data for a person other than the user.
This watch is designed on the premise of use by a single user. Since calculations made by the dive computer based on previous diving are continued to be used during operation in the surface mode, use of the watch by another person can prevent the dive computer from making calculations suitable for the user, resulting in the risk of an accident causing death or serious injury.
Avoid traveling in an aircraft while the surface mode is activated.
Traveling in an aircraft without allowing sufficient time to rest after diving results in the risk of decompression sickness. It is recommended to avoid traveling in an aircraft for at least 24 hours after diving whenever possible even if the surface mode is no longer displayed. There are no rules for completely preventing decompression sickness caused by flying in an aircraft after diving.

In the case of using this watch for diving, always make sure to also use other backup equipment (including a DCIEM dive table, divers watch, residual pressure gauge and water depth gauge).
Sudden fluctuations in the atmosphere and changes in water temperature may have an effect on the display and performance of the watch. Always make sure to use this watch in combination with other backup instruments in case the watch should happen to malfunction. The dive computer functions of this watch are not intended to completely protect you from decompression sickness and oxygen toxication. Since the watch is only intended to display information to serve as a reference for minimizing the risk of decompression sickness and so forth, it is not intended to completely ensure the safety of the user.
Always make sure to inspect all functions of the watch prior to each dive to prevent malfunction of the watch and accidents caused by use of the watch at improper settings. (Refer to the section entitled, "Cautions Regarding Use During Diving", for information on the inspection procedure.)
Diving when using this watch is limited to recreational diving at a water temperature from +10 deg. C to +40 deg. C (50 deg. F to 104 deg. F).
Do not use this watch for saturation diving using helium gas, diving at a water temperature outside the above temperature range or high-altitude diving at 3,000 m (10,000 ft) above sea level or higher since this can prevent the watch from functioning properly or lead to an accident resulting in danger. In addition, this watch does not display depth properly when used in water other than seawater (specific gravity of 1.025).
In order to ensure safe diving, dive while allowing an adequate margin of safety relative to the displayed no-decompression limit time.
If decompression diving should happen to occur, immediately start to ascend while observing an ascent rate of no more than 18 m (60 ft)/min.
Since decompression diving is associated with a high risk of decompression sickness, observe the following matters at all times.
* Make a decompression stop while ascending in accordance with decompression stop instructions. ?
* When making a decompression stop, never ascend to a depth less than the instructed depth.
* Since it is difficult to maintain a constant depth when there are high waves and so forth, make decompression stops at depths a little deeper than the instructed depth to prevent decompression sickness.
* A permanent error (ERROR) occurs when continuing to dive while ignoring decompression stop instructions during the course of decompression diving, and the watch will not switch to the dive mode for 24 hours after that time.
Skin diving after scuba diving is not recommended since it can have a serious effect on your health. It is recommended to avoid skin diving for at least two hours after scuba diving and not to exceed a depth of 5 m (15 ft).
DATA STORAGE
Always make sure to keep a separate record of important data recorded in the watch.
Diving data in particular should be transferred to your PC or recorded in a log book as quickly as possible. The various data recorded in the watch may be lost when subjected to incorrect use or the effects of strong electricity and electrical noise as well as during a malfunction and repair.
