Cal.D710 Cautions Regarding Use During Diving

* Cautions Regarding Use During Diving *

	When using the watch during diving, always make sure to receive the proper diving instruction and training and use the watch while obeying all rules. Failure to observe these matters can lead to decompression sickness, oxygen toxication or other accidents involving death or serious injury. * Please refer to these matters along with the section describing "Safety Precautions" for further details.
	.	In the case of using this watch for diving, always make sure to also use other backup equipment (including a DCIEM dive table, diver's watch residual pressure gauge and water depth gauge) to ensure safety.
	.	Inspect the watch to make sure that all functions operate properly before diving. . It is recommended to only use this watch for recreational diving down to a depth of about 18 m (60 ft). Do not attempt to dive below the limit depth of 40 m (131 ft) during recreational diving.
	.	Always make sure to allow an ample margin for no-decompression time.
	.	Perform adequate safety stops and decompression stops. Even in the case of nodecompression diving, always make a safety stop at 5 m (15 ft) to ensure safety. In addition, in the case the decompression stop display appears, try to stop for a period longer than that indicated on the display.
	.	Allow for a sufficient rest period after diving in accordance with safety rules. Boarding an airplane or moving to a high altitude without allowing for a sufficient rest period after diving results in the risk of decompression sickness.
	.	.
: Prohibited Use During Diving
	Never attempt to use this watch for diving under the following circumstances.
	.	When diving is prohibited in the system monitor mode: ...The watch will not switch to the dive mode when [ ] has changed to NG.
	.	When the watch has stopped running or an error has occurred (be careful not to bump the watch against hard objects such as equipment or rocks when diving).
	.	When measuring water depth outside the guaranteed temperature range or at an altitude of 3,000 m (10,000 ft) or higher ...The temperature range for which the water depth measurement accuracy of this watch is guaranteed is from +10 deg. C to +40 deg. C (50 deg. F to 104 deg. F). ...The water depth measurement function does not operate at high altitudes equivalent to 3,000 m (10,000 ft) above sea level or higher.
	.	When engaged in dangerous behavior or when a situation is judged to be dangerous: ...This watch is not built to function as a preventive or emergency instrument such as for use during marine accidents.
	.	When using in a helium gas atmosphere (saturation diving, etc.): ...Use under these conditions can cause a malfunction or damage to the watch.

Cautions Regarding Use During Diving
	<Cautions Before Diving>
	.	Sufficiently charge the watch and confirm that the watch is reliably charged and that the watch can be used for diving by referring to the system monitor mode. If the watch is not sufficiently charged, the watch will not switch to the dive mode even if diving is started. In addition, try to start a dive after first sufficiently charging the watch before diving to avoid having the watch become insufficiently charged while diving.
	.	During NITROX diving, check that the oxygen concentration (O2%) is correctly set to the oxygen concentration of the tank actually used before each dive. Diving with the oxygen concentration set incorrectly may cause incorrect information to be displayed during diving, greatly increasing the risk of decompression sickness and oxygen toxication. The oxygen concentration (O2%) cannot be set or changed while in the water and after a dive has been started. Always make sure to check and set the oxygen concentration prior to diving.
	.	Check whether "ERR (Error)", "CHK (Check)" or "CHRG (Charge)" is displayed on the display. If "CHRG (Charge)" is displayed, since this indicates that the watch is not fully charged, the watch may become insufficiently charged while diving.
	.	Confirm that the band is securely attached to the watch body.
	.	Confirm that the band and glass are free of cracks, scratches, chips and other abnormalities.
	.	Confirm that the time and date are set correctly.
	.	Confirm that the depth alarm and dive time alarm are set correctly.
	.	When there is a large difference between the temperature of the watch and the water temperature, immerse the watch in the water for at least 5 minutes to acclimate the temperature of the watch to the water temperature before diving. A large difference between the watch temperature and water temperature (such as in the case of placing the watch in water having after allowed it to sit in direct sunlight) can prevent water depth from being measured accurately.

	<Cautions During Diving>
	.	Avoid ascending too rapidly. A rapid ascent can cause decompression sickness and have other detrimental effects on the body. Observe the safe ascent rate at all times.
	.	Please note that when underwater, it may be difficult to hear the sound of the dive alarm or other alarms depending on surrounding conditions (such as breathing noise and air bubble noise) and the manner in which the watch is worn.
	.	Be careful not to run out of air. This watch does not manage the amount of air remaining in the air tank. The diver is responsible for managing the amount of air remaining.
	.	In the event the watch should happen not to operate properly while underwater, either ascend immediately while following the instructions of the instructor or begin ascending immediately at an ascent rate of no more than 18 m (60 ft) per minute and make a safety stop at 5 m (15 ft) as long as your air lasts.
	.	.
	<Cautions After Diving>
	.	Make sure to rest sufficiently after diving by referring to the surface mode (which measures the amount of time elapsed after diving and no fly time).
	.	After removing any moisture, mud, sand or other foreign matter adhered to the watch by thoroughly rinsing with fresh water, completely wipe off the watch with a dry cloth.
	.	Do not attempt to remove the sensor cover or poke at it with a sharp object to attempt to remove any dirt or debris trapped in the pressure sensor. In addition, do not spray the pressure sensor with air under high pressure such as that from an air gun. In the case that debris has become trapped in the pressure sensor, rinse it out with fresh water. If it is still unable to be removed, contact your nearest Citizen Service Center.
	.	.
<Diving in Fresh Water>
	.	Although this watch is compatible with high-altitude diving, since it is ultimately designed on the premise of diving in seawater, it does not display the correct water depth if used in water other than seawater.
	.	Only use this watch for diving in fresh water after having received special safety training. Since this watch displays water depth by converting on the basis of seawater (specific gravity: 1.025), the water depth is actually 2.5% deeper than the displayed depth. Example: Displayed water depth of 20 m x 1.025 = 20.5 m (actual water depth) (66 ft x 1.025 = 68 ft)
	.	Although an error occurs in the displayed water depth during freshwater diving at high altitudes and so forth, the calculations of the dive computer are performed correctly.
