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 three methods. You can also check whether the last attempt to receive the time signal was successful or not.
Page 30
Before receiving the satellite time signal When All Reset has been performed or you have manually adjusted the calendar, reception may take up to 70 seconds.
Page 31
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 32
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 with may obstruct the satellite time signal. Face the dial towards the sky and perform time signal reception.
Page 33
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).

Eco-Drive (solar powered) 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 (solar powered) watch handling precautions CAUTION Recharging Precautions • Do not charge the watch at a high temperature (about 60°C (140°F) or higher) as doing so may cause the movement to malfunction. Examples: - Charging the watch too close to a light source which generates a large amount of heat such as an incandescent lamp or halogen lamp. * When charging under an incandescent lamp, be sure to leave 50 cm (19-11/16 inch) or more between the lamp and the watch to avoid exposing the watch to excessive heat.
Page 71
Eco-Drive (solar powered) 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 72
Eco-Drive (solar powered) watch handling precautions WARNING Use Only the Specified Battery • Never use a battery other than the rechargeable cell specified for use in this watch. Although the watch structure is designed so that it will not operate when another type of battery is installed, if a silver battery or other type of battery is installed in the watch and the watch is recharged, there is the risk of overcharging which may cause the battery to rupture.
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 74
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 to water (washing general washing Skin diving, Scuba diving...

Precautionary items and usage limitations <Strong Shock> • Avoid dropping the watch or subjecting it to other strong impact. It may cause malfunctions and/ or performance deterioration as well as damage to the case and bracelet. <Static Electricity> • The integrated circuits (IC) used in quartz watches are sensitive to static electricity. Please note that the watch may operate erratically or not at all if exposed to intense static electricity. <Chemicals, Corrosive Gasses and Mercury>...
Page 79
Precautionary items and usage limitations CAUTION Always Keep Your Watch Clean • Rotate the crown while it is pressed in fully and press the buttons periodically so they do not become stuck due to accumulations of foreign matter. • The case and band of the watch come into direct contact with the skin in the same manner as undergarments. Corrosion of the metal or unnoticed soiling such as that caused by perspiration and dirt can soil sleeves and other portions of clothing. Keep your watch clean at all times. • The case and band of the watch come into direct contact with the skin. If you think there is something wrong, discontinue wearing the watch immediately and consult your physician.
Precautionary items and usage limitations Caring for Your Watch • Wipe any dirt or moisture such as perspiration from the case and crystal with a soft cloth. • For a metallic, plastic or rubber (urethane) watchband, wash any dirt off with water. Remove the small amounts of dirt trapped between the crevices of the metallic band with a soft brush. • For a leather band, wipe off dirt using a dry cloth. • If you will not be using your watch for an extended period of time, carefully wipe off any perspiration, dirt or moisture and store in a proper location, avoiding locations subject to excessively high or low temperatures and high humidity.
