CITIZEN QUARTZ ECO-DRIVE Model No. EP4XXX/EP3XXX Cal. No. B02/B03 · INSTRUCTION MANUAL
A. BEFORE USING This watch is not powered by an ordinary battery, but by converting photo energy into electric energy. Before using, expose to light and make sure the watch is fully charged. Since it takes time to recharge the watch until it starts running again once it has stopped, try to make sure the watch is charged every day. When the watch is stopped, the watch hands will begin to move when the watch is charged for about 5 hours in the case of the two-hand model or about 1 hour in the case of the three-hand model at 3000Lux (under a fluorescent light at a distance of about 20 cm (8 inch)). A secondary battery is used in this watch to store electrical energy. This secondary battery is a clean energy battery which does not use any toxic substances such as mercury. Once fully charged, the two-hand model will continue to run for about 5 months, while the three-hand model will continue to run for about 2 months, without further charging. To use this watch comfortably, make sure that the watch is always recharged before it stops. There is no risk of overcharging this watch. (Overcharge prevention function is included.) B. SETTING THE TIME
C. FUNCTIONS OF SOLAR POWERED WATCH If the charge becomes insufficient, a warning function will be activated that causes the display to change as shown below. Refer to the explanations of each function on the following page for further details.

Two Hand Model If sufficiently (Irregular one minute charged and interval movement) time is set : Minute hand moves irregularly in three steps once every minute
Recharge by exposing to light
If sufficient charge continues
Setting the time 1. Pull the crown out to the time setting position (the second hand will stop when the crown is pulled out in the case of the three-hand model). 2. Turn the crown to set the time. 3. After setting the time, firmly push the crown back in to the normal position.
Insufficient Charge Warning Function In the case of the two-hand model, the minute hand moves by one minute interval movement, and in the case of the three-hand model, the second hand moves by two second interval movement to indicate the insufficient charging. Although the watch keeps the correct time when this happens, the watch will stop after about 5 days in the case of the two-hand model or about one day in the case of the three-hand model, after the start of the one minute interval movement or two second interval movement. Recharge the watch by exposing to light. The watch will then begin to run normally again.
