PROHIBITION Circumstances that prohibit use of this watch in diving Don’t use this watch for diving under the following circumstances. • When the function hand indicates “NG” on the charging level index. … When the function hand indicates “NG” on the charging level, the watch will not measure the depth. If the function hand points at “NG” on the charging level during diving, immediately stop using the depth meter function of the watch since the watch discontinues depth measurement in this condition.
PAGE 10
• Avoid quick ascending, otherwise you may suffer from submarine sickness or a functional disorder in some way. Whenever you ascend in water, carefully keep a safe speed. • Don’t disturb any push buttons or the crown except button B (for knowing the memorized maximum depth) throughout the dive, otherwise the watch may fail in water-resistance. • After confirming that the crown is screwed down tightly, wash out seawater, mud, sand, etc. sticking to the watch, with fresh water.

Charge level indication The function hand indicates the charge level as follows (LV.1, LV.2 and NG) to let the user know whether the watch can be used for diving or not. In the diving mode, consumption of battery power is considerably increased because the pressure sensor and water sensor are actuated. Before using this watch for diving, charge the battery sufficiently and confirm the charging level which is indicated by the function hand.
PAGE 14
CAUTION • Use the indication of the charge level as a reference only. • If the watch is exposed to strong light for charging the battery, the function hand may temporarily indicate “LV.1” or “LV.2” despite insufficient charging. If the function hand goes to “LV.1” or “LV.2” from “NG” position in a short time, you need to pay careful attention to charging conditions. It is recommended that you keep the battery sufficiently charged all the time but especially before using the watch for diving.
PAGE 15
Stop warning function Time reset warning function Stop warning indication — Mode hand: “0” position, Function hand: “0” position — If the watch is left in the insufficient charge warning indication for two days, both the mode hand and function hand will move to “0” position respectively. If the watch falls into this condition, it indicates that the watch has stopped operation completely. (Stop warning indication) * All functions of the watch are inactivated in this indication.
PAGE 16
* Each time required for charging means a duration in which the watch is continuously exposed to the light indicated. 5. TIME REQUIRED FOR CHARGING Since time required for recharging the battery varies according to model (depending on the dial color, etc.), refer to the following table as a rough guideline for charging the battery. Time required for charging Illuminance (lux) Environment 500 Under indoor lighting 60-70 cm (24-28 in.
PAGE 17
6. SPECIAL CARE FOR THIS SOLAR POWERED WATCH • Mind that the battery power is apt to decline if you wear a jacket or a longsleeved shirt, because the watch is usually shaded by such clothes and the battery is insufficiently charged as a result. • Try to put the watch in a well-lighted place, as far as circumstances permit, when you take it off. If you do, the watch will continue normal running.
PAGE 18
7. SWITCHING BETWEEN MODES • Each time button A is pressed for two seconds, the mode is switched from the time mode to the chronograph mode and vice versa. • If the water sensor gets wet while the watch is in time mode, the mode is switched over to the diving mode. However, this mode shift is not performed when the function hand indicates “NG” on the charge level index. 10 50 .
PAGE 19
8. ADJUSTING TIME AND DATE (Time mode) Manner to adjust time The watch shows time and date in the Time mode. Besides time and date, the function hand indicates the battery power at three levels. Time (shown by hour, minute, second and 24-hour hands) and date can be checked any time regardless of the mode. Time can be adjusted in the Time mode.
PAGE 20
When the watch is immersed in the water, while it is set in the Time mode and the battery is charged enough for diving, the water sensor senses the water and switches the watch to Diving mode to measure the depth. In the Diving mode, the watch automatically memorizes the maximum depth of the last dive and the user can recall it after the dive. Function hand: * If the function hand and “0” position Mode hand: “DV” position Hour hand .2 LV G 1 N LV.
PAGE 21
Indication range: 0 to 50 m (0 to 125 ft) deep (measured every second) Indication unit: 1 m/5 ft (Decimals of five and above in the first decimal place are rounded up and anything under five in the first decimal place is rounded down. Depth less than 1 m/5 ft is indicated as 0 m/0 ft.) When the watch reaches the depth of 1 m/5 ft or more in diving, it starts measuring the depth. In diving, the indication by the function hand represents the depth.
PAGE 22
(1) Press button B in the Time mode or Diving mode 0m 3 6 (when depth indication is 0 m/0 ft). The function B hand indicates the memorized maximum depth. (2) To cancel the maximum depth indication, press button B again. * Indication of the memorized maximum depth continues for 30 seconds and is automatically canceled after that. * The memory of the maximum depth of the last dive 30 is held until the watch is used in the next dive.
PAGE 23
(1) In the Time mode, press and hold button A for 2 seconds or more to switch the watch to the Chronograph mode. As a result, both the function hand and mode hand quickly go to their respective “0” positions and then stop. (2) Each time button B is pressed, both the hands start and stop alternately. (3) If button A is pressed while both the hands are stopped, the chronograph switches to the reset status.
PAGE 24
11. MEASURES AGAINST POSSIBLE PROBLEMS If the solar powered watch is insufficiently charged or its battery power is considerably consumed, the watch functions are limited to a certain range and the watch warns the user of its status by various means such as abnormal indications. To avoid such a power failure, always try to charge the battery sufficiently. ● Some hand is out of the correct position.
PAGE 25
● The watch does not switch to the Time mode from the Diving mode (depth indication mode). When the user climbs to a high place or is on a flight, the watch may unexpectedly be shifted to the Diving mode because of a sharp change in the atmospheric pressure (pressure change equivalent to the depth of 1 m/5 ft). If it occurs, the watch may fail to switch from the Diving mode after the user goes back to the ground level, because the depth meter function didn’t reset the depth indication to “0 m (0 ft)”.
