[. . . ] Dive while allowing a sufficient margin for the nodecompression limit time to ensure safety. In the case you happen to engage in decompression diving, immediately begin ascending to the surface while observing an ascent rate of no more than 9 m (30 ft)/minute. When ascending, always make sure to make decompression stops according to a dive table to ensure sofety. 1. · It is recommended to avoid flying for at least 24 hours following the completion of diving. Carefully rinse off any seawater, mud or sand adhered to the watch and then wipe off any excess moisture with a dry cloth. Remove any debris or dirt that has become trapped in the pressure sensor. · If debris has become trapped in the pressure sensor, rinse it out with pure water. · Do not remove the sensor cover or poke the pressure sensor with a sharp object. In addition, do not blow highly compressed air onto the pressure sensor with an air gun. · Please consult with our service center if debris cannot be removed. Always make sure to store (record) important log data separately. 52 53 Diving Terms 1. Diving <No-Decompression Diving and NoDecompression Limit Time (NDL)> No-decompression diving (no-decompression limit: NDL) refers to diving during which the diver is able to surface without stopping for decompression while ascending following the completion of a dive. The limit time during which this no-decompression diving is allowed is referred to as the no-decompression limit time. No-decompression limit time varies according to the diving depth and diving time of the previous dives. <Decompression Diving> This refers to diving beyond the no-decompression limit time. Decompression diving is extremely dangerous since nitrogen accumulates in the body beyond allowed levels. <Decompression Stop> This refers to stopping for the purpose of required decompression in the event of having engaged in decompression diving. It is necessary to make decompression stops at predetermined depths (decompression stop instructed depth) and at predetermined times (decompression stop instructed time) when ascending. <Safety Stop> This refers to a temporary pause while ascending in order to ensure safety and allow nitrogen to be dispelled from the body even if the no-decompression limit time has not been exceeded. In the case of diving to a depth of 18 m (60 ft) or more, always make a safety stop at a depth of 5 m (15 ft) to ensure safety. <Dive Date> This refers to the date on which a dive was made (year, month, date). 54 <High-Altitude Diving and High-Altitude Setting> High-altitude diving refers to diving at a high location 300 m (1, 000 ft) above sea level (such as in lakes, ponds or rivers). [. . . ] Always make sure to use the specified energy storage cell when replacing. WARNING Repairs All parts of this watch, excluding the band, are to be repaired only at a Citizen Service Center. Please have all inspections and repairs performed at a Citizen Service Center. CAUTION Keep your watch clean WARNING Handling of Energy Storage Cell · Do not attempt to remove the energy storage cell from the watch. If the energy storage cell must be unavoidably removed, place it in a location out of the reach of children to prevent accidental swallowing. · If the energy storage cell is accidentally swallowed, contact a physician immediately and seek medical attention. · The case and band of the watch come in direct contact with the skin in the same manner as clothing.
