When the watch is fully charged, it will run for about 6 months. We recommended that you charge the watch for a long time in direct sunlight once a month. The insufficient charge warning a 2-second interval movement continues for more than 3 days. The watch will stop due to an insufficient charging. Sufficiently charge by exposing the watch face, which contains the solar cell to light.

The power saving function will be automatically canceled when the watch face is exposed to light. Return the second hand to 1-second interval movement by sufficiently charging the watch. Not exposed to light for 30 minutes or more Not exposed to light for 7 days or more 93 Page 48 B.

The watch will stop due to insufficient charging about 3 days after starting the 2-second interval movement if kept in a place with no light. Regularly charge your radio controlled watch so it does not become insufficiently charged. Overcharging Prevention Function When the secondary battery becomes fully charged by exposing the watch face to light, the overcharging prevention function is automatically activated to prevent the battery from being charged further.

No matter how much the watch is charged, it will not affect the secondary battery, timekeeping, functions or performance of the watch. Guide to Charging Time The charging time varies according to the model including the color of the watch face. The following data should only be used as a guideline. Charging time approximate Luminescence lx Environment Indoor lighting Time from stopping to For a 1-day resuming the movement charging time 1-second interval movement Time for full charging 3.

The charging time to run the watch for one day with normal movement. Time for full charging The time for full charging after the watch has stopped due to an insufficient charging. The watch will maintain its accuracy for about 2 and a half years when running in the power saving mode. Charge the watch every day, as it will take a long time to recharge it, as is indicated in the table, when it stops due to an insufficient charging.

If you must remove the battery, store it out of reach of children to avoid accidental ingestion. If the secondary battery is ingested, consult a doctor immediately. Doing so could cause a fire or environmental damage. Follow the collection procedures as specified by your local authority. Never use a regular silver battery. The battery could overcharge during the charging process and burst, causing damage to the watch or injuries to the wearer. Overheating while charging can cause the watch exterior to become discolored, the watch to deform or the movement to be damaged.

Radio signals cannot be received. When the second hand moves in 2-second intervals, the insufficient charge warning mark flashes in the digital display 1 and the charge level indicator points at level 0. Try to receive radio signals by pointing the position of the watch in the direction of the radio signal transmitter. Find a location such as window that is conducive to radio signal reception and change the watch location, direction and angle.

Problem The time is not correct. Check the reference position. The second hand moved suddenly to the reception standby RX position. The watch has stopped. The hands moved forward quickly at the moment that the watch was removed from a desk or drawer. The hands or digital displays are abnormal. Examples of use The unit "bar" is roughly equal to 1 atmosphere. Indication Dial Case case back Specifications Minor exposure to water washing face, rain, etc.

Moderate exposure to water washing, kitchen work, swimming, etc. For example, you may wear the watch while washing your face; however, it is not designed for use underwater.

You may wear the watch while swimming; however, it is not designed for use while skin diving. Otherwise, pressure inside the watch will increase, and parts crystal, crown, buttons, etc.

Rotate the crown while in its normal position, from time to time, to loosen dust and dirt and then brush it off. Deposited dust and dirt may cause corrosion and soil your clothing. Clean the watch occasionally. If your watch has a screw-lock type crown, be sure to tighten the crown completely. Water may enter the watch and compromise water-resistance. Leaving the watch in such a state will allow corrosion to form inside. Use a soft brush to remove dust and dirt jammed in the gaps in the metal band.

Instead, they have a solar conversion panel and an energy cell that work together to convert light to electricity, which is what the watch runs on. Although Citizen refers to the energy cell as a "secondary battery" in their literature and manuals, this wording can be misleading. Understand how your Eco-Drive works.

If your Eco-Drive watch stops completely, loses time or ticks erratically, it needs to be recharged, which can be done by exposing it to light.

Ideally, the watch should never stop, since it will remained charged up by normal day-to-day exposure to various sources of light as it is worn. However, if the watch does not receive enough light if it is left in a box or drawer, for example , it will lose power and need recharging.

Determine the amount of time and sunlight needed. The time required to recharge varies slightly by model, so consult your manual or the Eco-Drive website see References for details. Outdoor light is recommended for recharging your watch once it has stopped completely. Troubleshooting Troubleshooting 23 troubleshooting Citizen Eco-Drive Instruction Manual 71 pages.
