Notes on the reception of the time signal

Receiving the time signal

There are three ways to receive the time signal:

Methods

Automatic reception

Explanations

Receives the signal at 2:00 a.m. every day. If reception is unsuccessful, then, the watch tries to receive at 3:00 a.m. and 4:00 a.m.

On demand reception

Receives the signal when you want to adjust the time and calendar. See page

20

.

Recovery automatic reception

Receives the signal automatically after charging when the watch stops due to an insufficient charge.

The chronograph second hand indicates the receiving result (success/failure, levels) and the minute hand indicates the receiving station. (See page 21.)

22

• Even when this watch receives a time signal successfully, the accuracy of displayed time will be dependent on the reception environment and internal processing.

• If the watch is not able to receive a signal, it will operate normally within an accuracy range of ±15 seconds per month.

When receiving the time signal

Remove the watch and place it on a stable surface where it can receive the signal better, such as next to a window.

• The reception antenna is located at the 9:00 position of the watch. Place the watch with the

9:00 position facing toward the station.

• Do not move the watch during the time signal reception.

• The watch will not receive a time signal when in a low charge state as indicated by the second hand moving in two second increments (the insufficient charge warning).

Charge the watch before reception.

23

Poor reception areas

It may be difficult to receive the time signal properly 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

• Inside reinforced concrete buildings, between tall buildings, mountains, or underground

• Near electrical equipment or office appliances • Near cellular phones that are in use

24

When signal reception is poor

The surroundings near your house, such as high-tension electrical lines or structures may block the path to the signal location, this can cause a poor environment for receiving the time signal.

With reference to pages 17 to 24, search for a better place for reception.

Then, attempt to receive the time signal in the procedure on pages 20.

• When the reception result is “L”, place the watch in another location so that “H” or

“M” is indicated.

25

Setting the time/calendar manually

You can adjust the watch manually when the reception fails or you are unable to receive a signal.

Notes on charging your watch

This watch has a rechargeable cell which is charged by exposing the dial to light such as direct sunlight or fluorescent lamps.

For optimal performance:

• Expose the watch with the dial towards direct sunlight for several hours at least once a month.

• After taking off the watch, put it in a position so that the dial is exposed to bright light, such as by a window.

• Before storing the watch in a dark place for an extended period of time, be sure to charge it fully.

When the watch is regularly covered with long sleeves, it may not be charged sufficiently. Try to keep the watch exposed to light sufficient for charging.

Do not charge the watch at a high temperature (about 60˚C/140˚F or higher).

44

When the watch reaches a low charge state—insufficient charge warning function

When the power reserve becomes low, the second hand moves once every two seconds—This is the insufficient charge warning function. Charge the watch by exposing the dial to light.

• After the watch is charged, the second hand will move normally. See page 46.

• If you have not charged the watch for six days or more since the insufficient charge warning movement began, the watch will run out power and stop.

Caution

When the second hand moves once every two seconds, you cannot use any functions— chronograph, alarm, etc.—except the time indication.

Precautions

Warnings

Handling the rechargeable cell

• Do not remove the rechargeable cell. If it is removed, keep the rechargeable cell out of the reach of children to prevent ingestion.

• If the rechargeable cell is swallowed, consult a doctor and seek medical treatment.

54

Cautions

About charging

• Excessively high temperature when charging the watch may cause discoloration and deformation of the components, and result in malfunction of the movement.

• Do not charge the watch at a high temperature (about 50˚C/122˚F or higher).

Example:

- charging the watch too close to light such as an incandescent lamp or halogen lamp (Halogen lights are not recommended for charging due to their high heat output.)

- charging the watch in locations where the temperature may become extremely high—such as on the dashboard of a vehicle

55

To avoid injury

• DO NOT wear the watch where the temperature becomes extremely high—such as in a sauna. The watch may become hot and burn the skin.

To avoid malfunction

• DO NOT use the watch where the temperature is lower or higher than the operating temperature specified in this manual. Doing so may cause the watch to malfunction or stop.

• DO NOT place the watch nearby any materials generating a strong magnetic field such as:

– magnetic health equipment such as a magnetic necklace

– a magnetic latch of a refrigerator door

– a magnetic clasp on a handbag

– a magnetic coin tray

– speakers of a mobile phone

– electromagnetic cooking devices

They may interfere with function of the movement in the watch causing it to stop or operate erratically.

• DO NOT place the watch on or nearby household appliances that generate static electricity such as

Televisions or computer monitors. The timekeeping may be affected.

• DO NOT apply any strong shock, for example, by dropping it onto a hard floor.

56

• Avoid using the watch where it may be exposed to chemicals or corrosive gases. If solvents, such as thinners or benzine, or substances containing such solvents come in contact with the watch, discoloration, melting, cracking, etc. may occur.

The case, band, or other parts may become discolored if the watch comes into contact with some household chemicals mercury that may be found in thermometers.

57

Warnings on water-resistance performance

• Water-resistance for daily use: This type of watch is resistant to minor exposure to water such as accidental splashing. For example, you may wear the watch while washing your face; however, it is not designed to be used underwater.

• Upgraded water-resistance for daily use (tested to 5 bar): This type of watch is resistant to moderate exposure to water. You may wear the watch while swimming; however, it is not designed to be used for skin diving.

• Upgraded water-resistance for daily use (tested to 10 or 20 bar): This type of watch may be used for skin diving; however, it is not designed to be used for scuba or saturation diving.

• Before use, confirm the water-resistance level of your watch indicated on the dial and case, referencing the table on the next page. (The unit “bar” is roughly equal to 1 atmosphere.)

• “WATER RESIST(ANT) xx bar” may also be indicated as “W.R. xx bar.”

59

Cautions on exposure to water

• Be sure to use the watch with the crown pressed in fully (normal position) to ensure the water resistance. If the crown of your watch is the screw down crown, be sure to tighten it completely.

• Do not operate the crown or buttons when the watch is wet.

• If water has penetrated the watch, or if the inside of the glass is fogged up and does not become clear in a day, take the watch to your dealer or Citizen Service Center for repair. Leaving the watch in such a state will rust the internal parts and cause malfunction.

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

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

60

Keep your watch clean

• Keep your watch clean to prevent rust or dirt building up as this may stain your clothes, damage the watch or appear as black residue on your wrist. Depending on use, occasional cleaning of the exterior of your watch may be necessary.

• Wipe dirt off the leather band with a soft and dry cloth to prevent it from discoloring.

61

Maintenance

Daily maintenance

• Rotate the crown while it is pressed in fully and press the buttons periodically so they do not become stuck due to accumulations of foreign matter.

• Wipe off dirt, perspiration, and water from the case and glass with a clean soft cloth occasionally.

• To clean a metal, plastic, or rubber watchband, wash away dirt with water. Use a soft brush to remove dust and dirt stuck in the gaps in a metal band.

• Do not use a polishing type of cloth as this may damage the surface and certain treatments.

• Do not use solvents (thinner, benzine, etc.), as they may damage the finish.

Periodical inspections

Your watch needs an inspection once every two or three years for safety and longer usage. To keep your watch water-resistant, the gaskets and other components need to be replaced regularly. Other parts need to be inspected and replaced if necessary.

Always ask for genuine Citizen parts upon replacement.

62

Information

The time signal

The time signal is broadcast almost continuously 24-hours a day, but may occasionally be interrupted due to maintenance. The broadcasting conditions of the time signal can be checked on the station web site.

The time signal has no effect on the human body or medical equipment.

63

To avoid hand misalignment by impacts or magnetism

Impact detection function:

This function prevents unwanted movement of the hour, minute and second hands when the watch receives an impact.

Hand correction function (hand reference position auto-correction function):

The reference position of the hands is checked at regular intervals, and if there is any misalignment, the hour, minute and second hands are rapidly corrected to maintain the correct time.

64

Luminous dials and hands

The paint on the dial and hands helps you with reading the time in a dark place. The luminous paint stores light (daylight or artificial light) and glows in a dark place.

It is free from any radioactive substance or any other material harmful to a human body or environment.

• The light emission gradually becomes weaker as time passes.

• The duration of the light (“glow”) will vary depending on the brightness, types of and distance from a light source, exposure time, and the amount of the paint.

• The paint may not glow and/or may dissipate quickly if exposure to light was not sufficient.
