This is a GPS* solar watch. This watch has the following features. Features ＊GPS is an abbreviation for Global Positioning System. This watch can be set to the precise local time by just one button operation anywhere in the world. This watch operates by solar charging. This watch automatically adjusts the time in accordance with action patterns during use. Expose the dial to light to charge the watch. Once fully charged, the watch runs for approximately six months. When the energy stored in the watch runs out completely, it takes time to fully charge the watch, so please keep in mind to charge the watch regularly. → How to charge the watch　P.37 → Standard charging time　P.37 When the watch has sensed sufficient brightness under an open sky, it automatically receives GPS signals from GPS satellites. This function enables the watch to automatically adjust the time precisely even while you are using the watch. → Automatic time adjustment　P.46 ＊This watch is unable to receive GPS signals when the energy stored in the watch is low. → Check the Charging Status　P.36 This watch quickly adjusts the time by receiving GPS signals from GPS satellites. This watch responds to a total of 39 time zones around the world. When the region or time zone where the watch is used is changed, please carry out operation of “time zone adjustment.” → How to adjust the time 　　P.40 ※ Unlike navigation equipment, this GPS solar watch is not designed to constantly receive GPS signals from GPS satellites without any operation.This watch receives GPS signals only in the time zone adjustment mode, automatic or manual time adjustment mode. The watch displays the precise time of the time zone that is set by operation of “manual time adjustment.” → How to manually adjust the time 　P.45 → Check the time zone setting　P.40 To set only the time When the region or time zone where the watch is used is changed Adjust the time zone. The watch displays the precise local time. → Time zone adjustment 　P.39 Los Angeles 7:00 pm on 6th London 1:00 pm on 7th

Expose the dial to light to charge the watch. Standard Charging Time For an approximate time required to charge the watch, refer to the table at the right. GPS signal reception consumes a lot of energy. Keep in mind to charge the watch by expose to light so that the indicator hand points to the “level position (middle)” or “F (full).” (If the charging status is displayed as “E (low),” the reception will not start even with operation of GPS signal reception.) →Check the charging status.　P.36 About charging Reception is allowed Reception is not allowed Indicator display Charging status Solution F (full) Reception is allowed. Level position (middle) Reception is allowed, but keep in mind to charge the watch. Indicator display Movement of second hand Charging status Solutions One- second interval movement E (low) The watch is unable to receive GPS signals, but has energy to operate. Charge the watch at least until the indicator hand points to the level position so that the watch is able to receive GPS signals. Two- second interval movement The watch is unable to receive GPS signals, and does not have energy to operate. (The energy depletion forewarning function is activated. →P.49） Continue to charge the watch at least until the indicator hand points to the level position so that the watch is able to continuously operate and receive GPS signals. Five- second interval movement － The charging status is not displayed for the in-fl ight mode （） Reset the in-flight mode （）as long as possible. →Reset the in-fl ight mode （）　P.42 When the indicator hand points to “E,” charge the watch following the above. Check the charging status The indicator hand position shows whether this watch is able or unable to receive GPS signals. In addition, for the low charging state, the movement of the second hand shows the energy depletion state in further detail. ＊GPS radio signal reception requires a lot of energy. Keep in mind to regularly charge the watch by expose to light. 　→About charging　P.37 To ensure optima performance of the watch, make sure that the watch is kept suffi ciently charged at all time. Under the following situations, the energy of the watch is likely to be depleted, resulting in stoppage of the watch. ・ The watch is concealed under a sleeve. ・ The watch is used or stored under conditions where it cannot be exposed to light for a long time. ※ When charging the watch, make sure that the watch is not heated to a high temperature. (The operational temperature range is between -10 ℃ and + 60 ℃.) ※ When fi rst using the watch or starting to use the watch after it has stopped because of the energy depletion, suffi ciently charge the watch referring to the table on the page below. The fi gures of “Time required for charging the watch to start moving at 1-sec intervals” are estimations of time required to charge the stopped watch by exposing it to light until it moves at steady 1-sec intervals. Even if the watch is partially charged for a shorter period, the watch will resume 1-sec interval movement. However, it may shortly return to 2-sec interval movement. Use the charging time in this column as a rough guide for suffi cient charging time ※ The required charging time slightly varies depending on the design and the dial color of the watch.
