Cautions Regarding Use During Diving
Please make sure to observe the following matters before, during and after diving.
WARNING 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. The watch will not switch to the dive mode when “ERR” or “CHK” are displayed. 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 and then remove it from the water 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.
WARNING 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.
