Radio Wave Reception

5. For Best Reception

There are three kinds of reception: automatic reception, on demand reception, and recovery automatic reception. When the radio wave has been properly received, your watch will automatically adjust the time. When reception is complete, each of the hands will move either clockwise or counterclockwise to the received time.

Remove the watch from your wrist and place on a stable surface near a window where the radio wave can be easily received, pointing the 9:00 position in the direction of the radio wave transmitter.

Do not move the watch during reception.

• Reception may be difficult due to the surroundings or metal shielding.
  When inside a building, place the watch as close to a window as possible for good reception.
• Radio wave reception may be difficult during the hours around sunrise and sunset. Avoid attempting to receive radio waves during these times.

6. Poor Reception Areas

It may be difficult to properly receive the radio waves under certain environmental conditions or in areas susceptible to radio noise.

◆ Extremely hot or cold locations

◆ Near high-tension electrical lines, railway overhead wires or communication facilities

◆ Inside vehicles, including cars, trains and aero planes

◆ Near TVs, refrigerators, computers, fax machines and other electrical equipment or office appliances

◆ Near cellular phones that are in use

◆ Inside reinforced concrete buildings Between tall buildings or mountains, or underground

Solar Power

11. Solar Power Function

This watch uses a secondary battery to store electrical energy.

When the watch is fully charged, it will maintain its accuracy for about 6 months.

Always store the watch in a bright location for best results.

Placing the watch near a window where its face can receive sunlight or near another source of light when you are not wearing it will ensure that the watch is regularly charged, allowing it to maintain its accuracy.

◆ Wearing clothes with long sleeves makes it difficult for the watch to get the necessary light, resulting in insufficient charging.

It is recommended that the watch be left in direct sunlight once a month to charge it.

[NOTE]

Do not charge on surfaces that can easily become hot, such as a car dashboard.

12. Characteristics of the Solar Powered Watch

When the watch is insufficiently charged, the indication will be changed as follows:

[Normal indication] [Insufficient charge warning]

graph LR
    A["Watch with 2-second interval movement"] -->|The watch has been insufficiently charged because the watch face, which contains the solar cell, has not received sufficient light.| B["Watch with 2-second interval movement"]
    B -->|The insufficient charge warning (a 2-second interval movement) continues for more than 2 days.| C["Watch will stop due to an insufficient charging."]
    C -->|Sufficiently charge by exposing the watch face, which contains the solar cell to light.*1| D["Watch with recharged sufficiently, it will receive the radio wave automatically once."]

    E --> F["Two seconds are shown on the watch face"]
    F --> G["2-second interval movement"]
    G --> H["The second hand will begin a 2-second interval movement"]

*1. When the watch stopped due to insufficient charging

- It takes at least 30 minutes to recharge sufficiently to perform recovery automatic reception, even if the watch is being exposed to light. After recovery, refer to "Guide to Charging Time" (p.146) and sufficiently charge the watch.

*2. If the watch failed to perform recovery automatic reception

- The time is incorrect even if the second hand moves at 1-second intervals, so after fully charging the watch, set the time manually or perform on demand reception.

The insufficient charge warning (a 2-second interval movement) continues for more than 2 days.

When a radio wave has been successfully received*2

[Recovery automatic reception]

When the watch is recharged sufficiently, it will receive the radio wave automatically once.

Power Saving Function

If the watch face is not exposed to light for 7 days in succession, when the time reaches 12:00 midnight, the hands will stop and the watch will go into power saving mode.

- Even in power saving mode the watch will continue to keep time internally.

OK RX NO X Y Z

All hands stop at the 12:00:00 position.

The power saving function will be automatically canceled when the watch face is exposed to light.

• When power saving function is canceled, the hands will return to their normal movement.
• If the watch is insufficiently charged, the second hand will begin the 2-second interval movement. Charge the watch adequately to restore normal movement of the hands.

[NOTE]

• The power saving function cannot be canceled with crown or button operations. Cancel the power saving function by placing the watch in light.
• After the power saving function has been canceled, press the lower right button (A) once to check the reception status.

If it is not showing the correct time, carry out "On demand reception" (p.126) or "Setting the Time Manually" (p.132) before using.

Insufficient Charge Warning Function Overcharge

The second hand's movement changes from 1-second intervals to 2-second intervals to show that the watch is insufficiently charged. The watch will stop due to an insufficient charging about 2 days after starting the 2-second interval movement.

RUS RX NO cond mont

[NOTE]

During 2-second interval movement, automatic reception, on demand reception, time difference setting and manual time setting are unavailable.

2-second movement

◆If the charging insufficiency occurs during “Radio wave reception”, “Confirming reception status”, “Time difference correction” or “Checking/correcting the reference position”, the operation will stop automatically, the watch will return to the time before the operation, and 2-second interval movement will begin. Regularly charge your watch so it does not become insufficiently charged.

ention Function

Whenever the secondary battery becomes fully charged by exposing the solar cell 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.

* The charging time is based on continuous exposure.

Illuminance (lx)	Environment	Charging time
		For a 1-day movement charging time	Time from stopping to resuming the 1-second interval movement	Time for full charging
500	Indoor lighting	4 hours	20 hours	----
1,000	60-70cm beneath a 30W fluorescent light	2 hours	9 hours	----
3,000	20cm beneath a 30W fluorescent light	40 minutes	3 hours	190 hours
10,000	Cloudy sky	12 minutes	1.5 hours	60 hours
100,000	Direct summer sunlight	3 minutes	40 minutes	18 hours

* If the second hand is moving in 2-second intervals, refer to "Time for full charging" and fully charge.

For a 1-day movement charging time ... 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.

[NOTE]

A fully charged battery will run the watch for about 6 months without further 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.

Furthermore, it is recommended to charge your watch by exposing to direct sunlight for a long time once a month.

Handling Your Solar Powered Watch

CAUTION Charging precautions

◆ Overheating while charging can cause the watch exterior to become discolored, the watch to deform or the movement to be damaged.
Do not charge the watch in a high-temperature environment (about 60°C or more).

Example: • Charging close to incandescent lighting, halogen lamps, or other lighting sources that easily become hot.

- Charging on surfaces that can easily become hot, such as a car dashboard.

When charging with incandescent lighting, halogen lamps, or other lighting sources that easily become hot, place the watch at least 50 cm away from the source to avoid overheating.

WARNING Handling the secondary battery

Do not remove the secondary battery from the watch yourself, unless unavoidable. 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.

WARNING Changing the secondary battery

Although the secondary battery should never need to be changed, in rare instances, the watch may be unable to be charged due to a problem with the battery. If a problem occurs, have the watch repaired as soon as possible.

Troubleshooting

If you believe your watch may be inoperative, consult the following chart:

Problem Check Remedy
The watch does not receive radio waves.	Does the second hand align with the RX (receiving) position?	Press and hold the lower right button (A) until the second hand has reached the RX position.
The watch can receive the radio wave, but it does not show the correct time.The second hand does not align accurately with the OK/RX/NO positions.	Is the reference position set correctly?	Confirm the reference position.(p.120)If the reference position is not correctly set, refer to "Correcting the Reference Position" and correct the reference position.(p.136)

Problem Check Remedy
Reception is successful, but the time is out by a factor of hours.	·Check the time difference setting.	·Set the correct time difference setting. (p.134)
Radio wave cannot be received (where reception is possible).	·Radio waves may be interrupted occasionally due to special circumstances at the radio wave transmitter.	·Try to receive the wave again after a few hours.
	·Are there objects nearby that could block radio waves or generate noise? ·Are you attempting to receive the radio wave in a location far from a window?	·Avoiding objects that shield the radio waves and sources of radio noise, try to receive the wave with the 9:00 position of the watch pointing towards a window. Find a location such as window that is conducive to radio wave reception and change the watch location, direction and angle. (p.124)
	·Was the watch moved during reception while the second hand was aligned with the RX position?	·Do not move the watch until the radio wave has been properly received (until normal hand movement returns).

Problem Check	Remedy
The second hand is moving at 2-second intervals.The watch has stopped.The watch does not work even after charging.	Did you charge the watch sufficiently in sunlight?	Charge the watch sufficiently, as indicated in "Guide to Charging Time". (p.146)If the watch does not work even after charging, contact the Citizen Service Center.

Problem Check	Remedy
The hands moved forward quickly at the moment that the watch was removed from a desk or drawer.		This is because the power saving mode was canceled when the watch was exposed to light, and the hands moved forward quickly to the current time. It is ready to use. (p.142)

Precautions

For correct use within the design limits of the watch, confirm the level of water-resistance of your watch, as indicated on the dial and case, and consult the table.

WARNING: Water-resistance performance

There are several types of water-resistant watches, as shown in the following table.

The unit "bar" is roughly equal to 1 atmosphere.

* WATER RESIST(ANT) xx bar may also be indicated as W.R. xx bar.

Indication		Specifications
Dial	Case(case back)
WATER RESISTor no Indication	WATERRESIST(ANT)	Water-resistant to3 atmospheres
WR 50 or WATERRESIST 50	WATERRESIST(ANT) 5 bar orWATER RESIST(ANT)	Water-resistant to5 atmospheres
WR 100/200 orWATER RESIST100/200	WATER RESIST(ANT)10bar/20 bar orWATER RESIST(ANT)	Water-resistant to10/20 atmospheres

Minor exposure to water (washing face, rain, etc.)

Moderate exposure to water (washing, kitchen work, swimming, etc.)

Marine sports (skin diving)

Scuba diving (with air tank)

WARNING: Water-resistance performance

• Water-resistance for daily use (to 3 atmospheres): This type of watch is water-resistant to minor exposure to water. For example, you may wear the watch while washing your face; however, do not use while swimming.
• Upgraded water-resistance for daily use (to 5 atmospheres): This type of watch is water-resistant to moderate exposure to water. You may wear the watch while swimming; however, do not use while skin diving or scuba diving.
• Upgraded water-resistance for daily use (to 10/20 atmospheres): This type of watch may be used for skin diving; however, it is not designed for scuba or saturated diving using helium gas.

CAUTION

• Be sure to use the watch with the crown pressed in (normal position). If your watch has a screw-lock type crown, be sure that the crown is locked securely.
• Do NOT operate the crown or button when the watch is wet. Water may enter the watch and compromise water-resistance.
• The durability of a leather band may be affected when wet, owing to the properties of the material. In the case of a watch of upgraded water resistance for daily use that is frequently used in water, fading, peeling of adhesive or other problems may occur. It is therefore recommended to use another type of band (metal or rubber watchband).

• If the watch is used in seawater, rinse with fresh water afterward and wipe with a dry cloth.

• If moisture has entered the watch, or if the inside of the crystal is fogged up and does not become clear within a day, take the watch to your nearest Citizen Service Center for repair. Leaving the watch in such a state will allow corrosion to form inside.

• If seawater enters the watch, place the watch in a box or plastic bag and immediately take it in for repair. Otherwise, pressure inside the watch will increase, and parts (crystal, crown, buttons, etc.) may come off.

CAUTION: Keep your watch clean.

• Leaving dust and dirt deposited between the case and crown may result in difficulty in pulling the crown out. Rotate the crown while in its normal position, from time to time, to loosen dust and dirt and then brush it off.
• Dust and dirt tend to be deposited in gaps in the back of the case or band. Deposited dust and dirt may cause corrosion and soil your clothing. Clean the watch occasionally.

Cleaning the Watch

• Use a soft cloth to wipe off dirt, perspiration and water from the case and crystal.
• Use a soft, dry cloth to wipe off perspiration and dirt from the leather band.
• To clean a metal, plastic, or rubber watchband, wash away dirt with mild soap and water. Use a soft brush to remove dust and dirt jammed in the gaps in the metal band. If your watch is not water-resistant, take it to your dealer.
  NOTE: Avoid using solvents (thinner, benzine, etc.), as they may damage the finish.

CAUTION: Operating environment

• Use the watch within the operating-temperature range specified in the instruction manual. Using the watch where temperatures are outside the specified range, may result in deterioration of functions or even stoppage of the watch.
• Do NOT use the watch in places where it is exposed to high temperature, such as in a sauna. Doing so may result in a skin burn.
• Do NOT leave the watch in a place where it is exposed to high temperature, such as the glove compartment or dash-board of a car. Doing so may result in deterioration of the watch, such as deformation of plastic parts.
• Do NOT place the watch close to a magnet.
  Timekeeping will become inaccurate if you place the watch close to magnetic health equipment such as a magnetic necklace or a magnetic latch of a refrigerator door or handbag clasp or the carphone of a mobile phone. If this has occurred, move the watch away from the magnet and reset the time.
• Do NOT place the watch close to household appliances that generate static electricity. Timekeeping may become inaccurate if the watch is exposed to strong static electricity, such as is emitted from a TV screen.
• Do NOT subject the watch to a strong shock such as dropping it onto a hard floor.
• Avoid using the watch in an environment where it may be exposed to chemicals or corrosive gases.

If solvents, such as thinner and benzine, or substances containing such solvents come in contact with the watch, discoloration, melting, cracking, etc. may result. If the watch comes in contact with mercury used in thermometers, the case, band or other parts may become discolored.

Periodical inspections

Your watch needs inspection once in every two or three years for safety and long use.

To keep your watch water-resistant, the packing needs to be replaced regularly.

Other parts need to be inspected and replaced if necessary.

Ask for Citizen guine parts upon replacement.
