Page 32: Before Receiving The Satellite Time Signal
Before receiving the satellite time signal This watch receives the clock time information sent by satellite. This watch only receives time information. Location information cannot be acquired. ◆ Receiving the satellite time signal The satellite time signal can be received using the following two methods. You can also check whether the last attempt to receive the time signal was successful or not.
Page 33 Before receiving the satellite time signal When All Reset has been performed or you have manually adjusted the calendar, reception may take up to about 70 seconds.
Page 34 Before receiving the satellite time signal ◆ Cautions regarding receiving the satellite time signal Do not perform satellite time signal reception while operating a vehicle as doing so is extremely dangerous. • If the second hand is moving once every two seconds (insufficient charge warning function), you cannot perform satellite time signal reception. Charge the watch sufficiently before attempting time signal reception.
Page 35 Before receiving the satellite time signal ◆ When receiving the satellite time signal As shown in the picture below, make sure you are in an area with few surrounding trees, buildings, or other objects that may obstruct the satellite time signal. Face the dial towards the sky and perform time signal reception.
Page 36 Before receiving the satellite time signal • Receiving signals indoors near a window • Place the watch near a window with a wide view of the sky and orient the dial in an obliquely upward direction (approximately 45°). • If there are buildings, trees, or other obstacles above the window, satellite signals may not be able to be received. • The direction of the window that allow signal reception may be limited. Find the direction in which you can securely receive signals. • Satellite signals may not be able to be received through wire-reinforced glass or heat reflective glass (or film).
Page 37: Poor Reception Areas

Page 69: Eco-Drive Watch Handling Precautions
Eco-Drive watch handling precautions <Always Make Sure to Recharge Frequently> • Please note that if you wear long sleeves, the watch may stop as a result of being covered by your sleeve and blocked from the light. • When you take off the watch, try to place it in as bright a location as possible. This will ensure optimal operation.
Page 70 Eco-Drive watch handling precautions <Replacement of Rechargeable Cell> • This watch utilizes a special rechargeable cell that does not require regular replacement. However power consumption may increase after using the watch for a number of years due to wear of internal components and deterioration of oils. This may cause stored power to be depleted at a faster rate. For optimal performance, we recommend having your watch inspected (chargeable to the owner) by an Authorized Service center to ensure operation is within factory specifications.
Page 71: Water Resistance
Water resistance WARNING Water Resistance • Refer to the watch dial and the case back for the indication of the water resistance of your watch. The following chart provides examples of use for reference to ensure that your watch is used properly. (The unit "1bar" is roughly equal to 1 atmosphere.) • WATER RESIST(ANT) ××bar may also be indicated as W.R.××bar. • Non-water resistant models are not designed to come into contact with any moisture. Take care not to expose a watch with this rating to any type of moisture. • Water resistance for daily use (to 3 atmospheres) means the watch is water resistant for occasional accidental splashing.
Page 72 Water resistance • Upgraded water resistance for daily use (to 5 atmospheres) means that the watch may be worn while swimming, but is not to worn while skin diving. • Upgraded water resistance for daily use (to 10/20 atmospheres) means that the watch may be worn while skin diving, but not while scuba or saturated diving using helium gas. Water-related use Minor exposure Swimming and Operate the crown Skin diving, Scuba diving to water (washing general washing...
