Citizen JNOXXX instruction manual Conversion

10.Conversion

Example: Convert 30 statue miles into nautical miles and kilometres.

Operation: Align “30” on the outer scale with STAT (▲) on the inner scale. Then, NAUT (▲) on the inner scale corresponds to “29” nautical miles on the inner scale, and “12 km”(s) on the inner scale corresponds to “48.2” km on the outer scale.

B. General Calculation Functions

1.Multiplication Example: 20 x 15

Answer: Align the “20” on the outer scale with “10” on the inner scale. Then, “15” on the inner scale corresponds to “30” on the outer scale. Take into account the position of the decimal point and add one zero to obtain 300. Note that with the scales

of this watch, the position of the decimal point cannot be obtained.

2.Division Example: 250 / 20

Answer: Align “25” on the outer scale with “20” on the inner scale. Then, “10” on the inner scale corresponds to “12.5” on the outer scale. Take into account the position of the decimal point to obtain 12.5.

3.Proportion

Example: 30/20 = 60/x

Operation: Align “30” on the outer scale with “20” on the inner scale. Then, “60” on the outer scale corresponds to “40” on the inner scale. At this point, the proportion for every value on the inner and outer scales is 30:20.

4.Square root

Example: Square root of 225

Operation: Turn the outer scale slowly and find a value that corresponds to both “22.5” on the outer scale and “10” on the inner scale. In this example, ‘‘22.5’’ on the outer scale corresponds to “15” on the outer scale. Thus, the answer is 15.

To Keep Your Watch in Good Condition

Water resistance

*To prevent water from coming into contact with the internal mechanism of the watch, never pull the crown out when the watch is wet.

*If your water-resistant watch is exposed to salt water or significant amounts of sweat, rinse it in clean water and dry thoroughly.

*Exposure to water will diminish the durability of most types of leather bands.

*The internal parts of the watch may hold some moisture. If the external temperature is lower than that inside the watch, the crystal may get fogged up. Temporary fogging does not pose a problem. If it persists for a prolonged period, we recommend that you have your watch checked by your authorised dealer or a Citizen Service Centre.

Temperature

Avoid exposing the watch to direct sunlight or leaving it in an extremely hot or cold location for prolonged periods.

*This will cause malfunctioning and shorten the life of the power cell.

*This may cause your watch to gain or lose time, and affect its other functions.

Shock

*This watch will withstand bumps and jars normally incurred in daily use or while playing non contact sports such as golf.

*Dropping the watch on a hard floor or otherwise applying shock to it may cause malfunction or damage.

Magnetic Fields

This watch is antimagnetic up to 60 gauss and will not be affected by the magnetic fields produced by ordinary household electrical appliances. If used in the immediate vicinity of strong magnetism, however, the functions of the watch may temporarily be affected.

Static electricity

The integrated circuits used in the watch are sensitive to static electricity. If exposed to intense static electricity. the display may be adversely affected.

Chemicals and Gases

Avoid wearing the watch in the presence of strong chemicals or gases. If the watch comes in contact with solvents such as thinner and benzine or products containing materials such as gasoline, polish, detergent or adhesive, its components may discolour, dissolve or crack. Be especially careful to avoid chemicals. The watchcase and band may become discoloured if they come in contact with mercury. such as from a broken thermometer.

Keep your watch clean

When the watch has been worn for a prolonged period, pulling the crown out may become difficult because of dirt and dust caught between the crown and the watchcase. To help prevent this from happening, rotate the crown back and forth occasionally while it is in the normal position.

Wipe off any moisture that adheres to the case, crystal and band with a soft, clean cloth. Dirt left on the case or band may cause a skin rash.

A watch band will easily become soiled with dust and perspiration, as it is in direct contact with the skin. Even a stainless steel or gold-plated band may begin to corrode if it has not been cleaned for a prolonged period.
