1. Your Watch

iAutomatic reception function: Every morning at 2 a.m. and 4 a.m. the watch

will automatically receive the radio wave and adjust the time.

However, if reception is successful at 2 a.m., automatic reception will not be

performed at 4 a.m.

iOn demand reception function: The radio waves can be received at any time

of the day to adjust the time.

* Not possible when the radio wave is interrupted

iEco-Drive function: This solar powered Eco-Drive watch is equipped with a

solar power function for powering the watch by converting light energy into

electric energy. The watch incorporates a power saving function that reduces the

electrical power consumption when the watch face is not exposed to light.

iTime difference adjustment function: The watch incorporates a convenient

time difference adjustment function (±27 hours).

A simple method is available for changing to the local time if you are going to

an area in a different time zone.

2. Operating the Crown

There are two models available for the crown: normal and screw lock.

When the crown is pulled out to the position 1

and quickly turned to the left or right (more than 2

clicks), the hands will rotate continuously.

To stop the continuous movement of the hands,

turn the crown to the left or right by one click.

* A gentle “click” can be felt by the fingertips.

• Turn the crown

to the left.

Using the side of your finger, quickly

turn the crown by two or more clicks.

Turn to the left

• When the screw lock is

released, the crown

pops out a little and

stops in the normal

position. After

finishing the operation,

lock the crown again.

Before using the watch, check that the hands are aligned with

“0”, similar to when setting weighing scales

iThe reference position may become misaligned when the

watch is exposed to strong magnetism, static electricity or

impacts.

Even if radio waves are received, the correct time will not be

indicated unless the watch hands are aligned to the correct

reference position. Check that the hands are properly aligned

with “0”.

Examples of magnetic products that can affect the watch.

• Health products (for example, medical necklaces and waist bands that have

magnetic fields)

• Refrigerators (magnetic part of the door)

• Electromagnetic cookers

• Bags (with magnet fasteners)

• Mobile phones (speaker part)

Keep the watch away from items similar to those above.

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.

124

jExtremely hot or cold

locations

jNear high-tension electrical

lines, railway overhead wires

or communication facilities

jInside vehicles, including

cars, trains and aero planes

jNear TVs, refrigerators,

computers, fax machines and

other electrical equipment or

office appliances

jNear cellular phones

that are in use

jInside reinforced concrete

buildings

Between tall buildings or

mountains, or underground

Radio Wave Reception

2. Press the lower right button (A) for more than 2

seconds and release it when the second hand stops

at the RX position.

3. When reception is complete, the second hand will

leave the RX position and return to normal

movement.

Referring to “Confirming the Reception Status”

(p.128), check the reception status.

Recovery Automatic Reception

iIf the watch stops due to insufficient charging, expose

the watch to sunlight to recharge it. When the watch

is recharged sufficiently, it will automatically receive

the radio wave once. Please remember to keep the

watch charged to prevent this situation from occurring.

jIf the lower right button (A) is pressed for more than 2 seconds during reception,

the reception will be cancelled and the hands will return to their normal movement.

7. Receiving the Radio Waves

Automatic Reception

iPlace the watch in a stable location near a window where the radio wave can be

easily received with the 9:00 position pointing towards the transmitter. The watch

will receive the radio waves at 2 a.m. every day. If the radio wave cannot be

received at 2 a.m., it will try again automatically at 4 a.m.

On Demand Reception (Manual Reception)

Radio waves can be received at any time.

* Not possible when the radio wave is interrupted

Use this function when automatic reception is impossible due to changes in the

reception environment.

(Depending on the weather or noise conditions, reception can take up to 15

minutes.)

1. 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.

The second hand stops

at the RX position.
