■ NOTICE ON CHARGING

• The charger may make a subtle noise while charging. However, it is not a malfunction.

• The main body may heat up while charging, however, it does not affect the functions

of the watch.

• Be careful with the temperature of the watch, when handing the watch to the cus-

tomer.

■ HOW TO SET THE TIMER

• This charger is designed to charge SEIKO KINETIC watches, which already run down. Usually set the timer to “30 min.” (for approximately 30 minutes), which is long enough to charge SEIKO KINETIC watches so that they resume their normal operational movement in one-second intervals.

• The 3 1/2 hour timer (for approximately 3 hours and a half) can be utilized especially when charging several SEIKO KINETIC watches successively or when supplying more energy.
