[. . . ] The watch automatically switches to the flash memory status display of Flashing the system monitor mode when the water sensor gets wet while this warning function is activated. Please note that although it is possible to use the watch for diving in this state, log data may not be recorded in flash memory during diving. The file error warning function is also activated and additional log data is not recorded if the duration of a single dive exceeds 2 hours or if more than 15 dives are made in a single day. The file error warning function may also be activated when the water temperature during diving is low. It may not be possible to receive watch settings by data communication while the file error warning function is activated. When the watch has switched to the file error warning display, perform the garbage collection procedure in the system monitor mode of the standard mode. The display returns to normal following completion of garbage collection. 48 Abnormal Pressure Detection Error Warning When abnormal atmosphere pressure is detected during use on land, or when ascending to high locations more than 3, 000 m (10, 000 ft) above sea level, "ERR" (Error) flashes in the lower left corner of the display. The watch does not switch to the dive mode even if the water sensor gets wet while this warning function is activated. Flashing If "ERR" does not disappear from the display even after a long period of time, there may be a problem with the pressure sensor. When this happens, discontinue using the watch and consult a Citizen Service Center. Water Sensor Check Warning If the preliminary dive display continues to be displayed for more than 1 hour after the water sensor has gotten wet and the watch has switched to the preliminary dive display in the dive mode, "CHK" (Check) flashes in the lower left corner of the display to inform the wearer that the water sensor should be checked. Flashing * "CHK" also flashes when the watch returns to the normal display from any of the correction states, when the watch is returned to the time mode of the standard mode from the infrared communication mode, and when the water sensor is operating during the all reset procedure. The watch does not switch to the dive mode (water depth measurement display) when "CHK" is flashing. To check the sensor, remove any debris or moisture from the water sensor with a dry cloth. The display returns to normal when the water sensor is canceled. Ascent Rate Warning When the ascent rate during scuba diving exceeds 18 m (60 ft)/min, the ascent rate warning alarm sounds for 5 seconds and "SLOW" and an illustration of a turtle are displayed at the bottom of the display. The ascent rate warning alarm stops sounding when a proper ascent rate is resumed. * The ascent rate warning alarm does not sound during skin diving (continuous diving for less than 3 minutes at a depth of 1 m (4 ft) or more). Abnormal Depth Warning When a sudden change in depth of more than 4 m (13 ft)/sec is detected during diving, the watch assumes that the watch has reached an abnormal depth. At this time, "ERR" and the diver mark are alternately displayed in the lower left corner of the display. Once "ERR" has been displayed during diving, it continues to be displayed until the dive mode is terminated. Flashing CAUTION Avoid using this watch in environments subject to sudden changes in water pressure such as when using ocean floor excavation or similar equipment. The vibrations from such equipment may cause a change in water pressure of "4 m (13 ft) or more per second" to be locally and momentarily applied to the pressure sensor of the watch, causing "ERR" to be displayed and preventing water depth from being displayed correctly. 49 Exceed Maximum Depth Warning When the limit depth of 40 m (131 ft) for recreational diving is surpassed during the course of diving, an exceed maximum depth error occurs, the current depth flashes and the alarm sounds for 15 seconds. During diving at a depth greater than 40 m (131 ft), the warning alarm sounds for 15 seconds every minute. This warning function is canceled when the depth returns to 40 m (131 ft) or less. Flashing Decompression Diving Warning This alarm sounds for 3 seconds and the decompression stop indicator (STOP) is displayed on the display when the no-decompression limit time has been exceeded resulting in decompression diving during the course of diving. The display returns to the no-decompression diving display when decompression stop is performed in accordance the decompression stop instructions. Decompression Diving Error When decompression diving takes place beyond the no-decompression limit time during diving in the NITROX setting, together with the alarm sounding for 1 second and the decompression stop indicator (STOP) being displayed on the display, the instructed depth and instructed time flash. During a decompression diving error, the instructed depth and instructed time continue to flash, and the alarm sounds for 15 seconds every minute. Flashing Ascend to a shallow depth at a safe ascent rate as soon as possible. The display returns to the no-decompression diving display when a decompression stop is performed in accordance with the decompression stop instructions. Permanent Error Warning The instructed depth flashes and an alarm sounds continuously when either of conditions 1 or 2 below are met. If hazardous diving or ascending is continued while ignoring this warning, a permanent error (ERROR) occurs: 1. When not ascending to the instructed depth and continuing to dive at an excessively low depth (diving at which the instructed decompression stop depth exceeds 9 m (30 ft). ) even though having been instructed to make a decompression stop (Permanent Error Warning 1). [. . . ] · Avoid the use of solvents (such as thinner or benzine) as they may damage the finish. CAUTION Precautions When Wearing the Watch · Be careful while wearing the watch while holding an infant or child, by taking the watch off beforehand, to prevent injury or other accident. · Be careful when engaged in vigorous exercise or work to prevent injury and accidents to yourself and others. · Never wear the watch in a sauna or other locations where the watch can reach high temperatures since this can cause burns. CAUTION <Temperatures> Handling of the Band (Cautions when Putting on and Taking Off the Watch) Depending on the structure of the band buckle, be careful not to injure your fingernails when putting on and taking off the watch. The watch may not function or stop running if exposed to temperatures outside the range of 0°C to 50°C (32°F to 122°F). [. . . ]
