Eco-Drive (solar powered) watch handling precautions

•Foroptimalperformance,yourwatchshouldremainfullycharged.

•Longsleevesmayinhibitlighttransmissiontoyourwatch.

Thismayresultinyourwatchloosingcharge.Inthesecases

supplementalchargingmaybenecessary.

•Whenyoutakeoffthewatch,placeitinabrightlocationtoensure

optimalperformance.

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(20inches) or more between the lamp and

the watch to avoid exposing the watch to excessive heat.

•Chargingthewatchinalocationwherethetemperature

may become extremely high such as on the dashboard of

a vehicle.

Eco-Drive (solar-powered) watch handling precautions

•Thiswatchutilizesaspecialrechargeablecellthatdoesnotrequireperiodical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

every 2-3 years for proper operation and condition check.

WARNING

Handling of Rechargeable Cell

•Therechargeablecellshouldneverberemovedfromthewatch.

If for any reason it becomes necessary to remove the rechargeable cell from the watch, keep out

of the reach of children to prevent accidental swallowing.

If the rechargeable cell is accidentally swallowed, consult a doctor immediately.

•Donotdisposeoftherechargeablecellwithordinarygarbage.Pleasefollowtheinstructionsof

your municipality regarding collection of batteries to prevent the risk of fire or environmental

contamination.

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 conventional watch 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.

This can cause damage to the watch and injury to the wearer.

When replacing the rechargeable cell, always make sure to use the designated rechargeable cell.
