CAMERA MODE

Use the Camera Mode to record images. The lens for image recording is located on the top edge of the watch.

To record an image

1. Press

F

to enter the Camera Mode.

•

Note that you cannot enter the Camera

Mode from the IR Mode.

2. While viewing the image on the display, point the lens of the watch at the subject whose image you want to record.

3. Press

F

to release the shutter and record the image.

•

This records the image currently on the display and stores it into memory.

The image remains on the display for about two seconds as the record operation is being performed.

— 3 —

Note

•

All watch button operations are disabled while the record operation is in progress.

•

The watch stays in the Camera Mode for about one minute after you enter it. Then it automatically enters the VISUAL DATABANK Mode and displays the last image recorded. See “Camera Rest Interval” for more information.

•

The message FULL appears on the display to indicate that memory is full.

You will not be able to enter the Camera Mode while this message is displayed. If this happens, delete images you no longer need to make room for more images.

Camera Mode Precautions

General

•

Never touch the surface of the lens with your fingers.

•

Take care that you do not accidentally move the watch when you press

F to release the shutter.

•

Insufficient lighting can result in poor images. Shoot in daylight whenever possible. At night, shoot indoors in a well-lit area.

Camera Rest Interval

Camera Mode operations consume considerable battery power. To protect against premature rundown of its battery, the watch automatically goes into a rest interval, during which you will be unable to re-enter the Camera Mode after you exit it. The length of the rest interval is equal to the amount of time you spent in the Camera Mode before you exited it. This means that if you exit the Camera Mode after being in it for 20 seconds, you will be unable to re-enter the Camera Mode for about 20 seconds.

REC

WAIT

18

If you try to enter the Camera Mode during a rest interval, the message WAIT appears on the display, along with a countdown of the remaining rest interval time.

•

The maximum rest interval is 60 seconds.

Remaining rest interval time

Alarm, Hourly Time Signal, Countdown Alarm Sounds

The watch does not emit any alarm, Hourly Time Signal, or Countdown Alarm sound while it is in the Camera Mode.

Controlling the Camera Mode Image

You can use the following procedures to adjust the brightness and to specify the type of lighting present when recording an image.

Adjusting the Image Brightness

The watch automatically sets the brightness of the image when you record it.

You can also change the brightness level manually when you want to compensate for backlighting of the subject, very dark backgrounds, etc.

To adjust image brightness

Darker

Lighter

When composing an image on the display, use

B

(darker) and

E

(lighter) to adjust its brightness.

•

You can set brightness to one of 15 levels.

The initial default level is 8.

•

It may take some time after you press

B

or

E

before the change in brightness is reflected on the displayed image.

•

A brightness setting you make remains in effect until you change it or exit the Camera

Mode. Automatic brightness adjustment is the initial default whenever you enter the

Camera Mode.

Important!

•

Even with manual brightness adjustment, you may not be able to obtain an acceptable image when recording images under very bright or very dark lighting conditions.

Specifying the Lighting Type

The type of lighting present when recording, greatly affects the resulting image. Besides the difference between outdoor and indoor lighting, there is also a difference between indoor lighting types.

Though you cannot see it, light produced by indoor lighting fixtures actually flickers at a fixed rate, which is the same as the cycle of the lighting fixture’s

AC power (50Hz or 60Hz). You can use the following procedure to tell the watch the type of lighting you are using, so it can make necessary adjustments that ensure best results.

To specify the lighting type

In the Camera Mode, press

A

to cycle through the available lighting type settings as shown below.

Outdoor 50Hz Indoor 60Hz Indoor

OUT

DOOR

IN

DOOR

5‰

HZ

•

The lighting type setting screen remains on the display for about one second. After that, it returns to the normal Camera Mode screen.

•

A lighting type setting you make remains in effect until you change it or exit the Camera Mode. Outdoor lighting is the initial default whenever you enter the Camera Mode.

Recording Modes

There are three recording modes that you can use to produce the type of image you want.

Normal Mode

This mode records images using 16 grayscales. It is the normal default mode.

Merge Mode

This mode lets you merge two separately recorded images into a single image.

Art Mode

This mode records images in two-tone monochrome.

To select the recording mode

In the Camera Mode, press

C

to cycle through the available recording modes as shown below.

Normal Mode Merge Mode Art Mode

•

The recording mode you select remains in effect until you change it or exit the Camera Mode. The Normal Mode is the initial default whenever you enter the Camera Mode.

To record using the Merge Mode

First image

Second image

1. In the Camera Mode, press

C

once to select the Merge Mode.

2. Compose the first image, and then press

F

to record it.

•

This records the first image on the left half of the display.

3. Compose the second image, and then press

F

to record it.

•

This records the second image on the right half of the display, and stores both images in memory.

Important!

•

A Merge Mode image that has only a left side cannot be stored in memory.

Note

•

Before pressing

F

in steps 2 and 3 of the above procedure, you can use the procedure (“To adjust image brightness”) to adjust the brightness of the image.

To record using the Art Mode

1. In the Camera Mode, press

C

twice to select the Art Mode.

2. Compose the image, and then press

F

to record it.

VISUAL DATABANK™ MODE

Besides viewing images, you can use the VISUAL DATABANK Mode to delete images, to attach text to images, etc.

Important!

•

The watch does not emit any alarm, Hourly Time Signal, or Countdown

Alarm sound while it is in the VISUAL DATABANK Mode. Instead, the message ALM flashes in the upper left corner of the display when an alarm time is reached, and the message TMR flashes when the countdown reaches zero.

To view recorded images

1. In the Timekeeping Mode, press

D

to enter the VISUAL DATABANK

Mode.

•

Communication failed for some reason.

Try again.

•

Watch memory is full. Delete images you no longer need and try again.

•

Communication link with sender was broken. Re-align watches and try again.

Communication Precautions

•

The two watches must be within 10cm (4 inches) and 30 degrees of each other.

•

Proper data communication may also be impossible if the two watches are too close to each other.

•

Do not move the watches while communication is in progress.

•

Make sure there is nothing between the two watches that blocks the path of the IR signal.

•

Infrared communication may not be possible in areas where lighting is bright, near a window, etc. Perform data communication under normal room lighting (about 500 lux).

•

The maximum allowable distance between watches may be less than

10cm when the watch is warm.

•

An unrelated nearby IR data communication operation can interfere with proper IR data communication between two watches.

•

The maximum allowable distance between watches may be less than

10cm when watch battery power is low.

•

The watch automatically returns to the COM (IR Mode) menu about five minutes after the image selection screen or receive standby screen is displayed. If the point where five minutes elapse occurs while a data send/ receive operation is in progress, the operation continues until it is complete, after which the watch automatically returns to the COM menu.

•

Never leave a dead or weak battery in the battery compartment. Doing so runs the risk of damage and malfunction due to battery fluid leaks.

•

Be sure to dispose of old batteries according to the local laws and regulations in your area.

•

Improperly replacing the battery can result in damage to the watch.

Repairing such damage will be charged to you, so take care to replace the battery correctly.

•

Never try to take the battery apart, or expose it to heat or direct flame.

Take care that the positive and negative ends of the battery never become shorted.

•

The battery installed at the factory is not rechargeable. Never try to charge it.

•

Should battery fluid ever leak inside the battery compartment, immediately use a dry rag to wipe it out while taking care not to get any fluid on your hands.

Keep batteries out of the reach of small children. If accidentally swallowed, immediately contact a physician.

•

Note that CASIO shall not be held responsible for any damage or loss, including but not limited to lost profits, by you or any third party due to data deletion or modification due to malfunction, repairs, battery replacement, etc.

Battery Precautions

Incorrectly using a battery can cause it to burst or leak, possibly damaging the interior of the watch. Note the following precautions.

•

This watch is powered by a single CR-2032 lithium battery.

•

We strongly urge use of battery type specifically recommended in this manual.

•

Damage to or dirt, dust, moisture on the inside of the battery cover or on the surface that comes into contact with the rubber seal (gasket) can cause loss of water resistance. Keep such areas clean and free of moisture.

2. Remove the old battery.

•

If you have trouble removing the battery, try turning the back of the watch downwards so it falls out.

•

Take care that you do not lose the battery compartment gasket.

•

Keep your fingers away from the spring inside the battery compartment. The sharp edges of the spring create the risk of personal injury.

3. Load a new battery.

•

Wipe the surfaces of a new battery with a dry cloth, and load the battery into the watch with its plus (+) side facing up (so you can see it).

•

Never pick up the battery with tweezers contacting the top surface and bottom surface at the same time. Doing so creates a short.

•

If the gasket comes out when you remove the battery, be sure to replace it before loading the battery. You will not be able to load the battery properly if the gasket is not in place.

•

Whenever replacing the gasket, check it to make sure there is not dust or dirt on it.

•

Note the triangular shape of the gasket material. The flat surface (the base of the triangle) is the bottom, which should be against the watch body when the gasket is installed. The pointed surface (the peak of the triangle) is the top, which contacts the battery cover.

4. Close the battery cover.

•

Replace the battery cover, and rotate it to the CLOSE position using a coin or other similar object.
