To indicate the risks of serious consequences such as severe injuries unless the following safety regulations are strictly observed. • Immediately stop wearing the watch in the following cases. • Avoid wearing or storing the watch in the following places.
READ FIRST ASTRON 8X82 GPS SOLAR CONTENTS 1 CAUTIONS WARNING Do not use the watch in scuba diving or saturation diving. Do not turn or pull out the crown when the watch is wet. The various tightened inspections under simulated harsh environment, which are usually required for watches designed for scuba diving or saturation diving, have not been conducted on the water-resistant watch with the BAR (barometric pressure) display. For diving, use special watches for diving.
READ FIRST ASTRON 8X82 GPS SOLAR CONTENTS 1 Features This is a GPS solar watch. GPS is an abbreviation for Global Positioning System. For details, see P. 5 This watch has the following features. GPS signal reception Solar charging Function This watch can be set to the precise local time by just one button operation anywhere in the world. DST (Daylight Saving Time) can be set manually. This watch quickly adjusts the time by receiving GPS signals from GPS satellites.
READ FIRST ASTRON 8X82 GPS SOLAR CONTENTS 1 Mechanism by which the GPS solar watch sets time and date What GPS is GPS stands for Global Positioning System, a satellite positioning system for determining the current position on the earth. 24 satellites cover the earth, and at present, the system is operated by approximately 30 GPS satellites. Wherever you are in the world, the position can be determined (positioned) by information from more than 4 GPS satellites.
READ FIRST ASTRON 8X82 GPS SOLAR CONTENTS 1 Time zone Time zone 0 -1 Based on Coordinated Universal Time (UTC), the standard time commonly used is adopted by countries and regions around the world. The standard time is determined by each country or region, and the region where the same standard time is adopted is referred to as the time zone, and presently, the time zone is divided into 40 zones.
READ FIRST ASTRON 8X82 GPS SOLAR The following functions are included To set only the time When the region or time zone where the watch is used is changed The watch displays the precise time of the time zone that is set by operation of “manual time adjustment.” Adjust the time zone.
