Backlight

The backlight uses an EL (electro-luminescent) panel that

Auto light switch on indicator

causes the entire display to glow for easy reading in the

dark. The watch's auto light switch automatically turns on

the backlight when you angle the watch towards your

face.

• The auto light switch must be turned on (indicated by

the auto light switch on indicator) for it to operate.

• See "Backlight Precautions" for other important

information about using the backlight.

To turn on the backlight manually

In any mode, press B to illuminate the display for about two seconds.

• The above operation turns on the backlight regardless of the current auto light

switch setting.

About the Auto Light Switch

Turning on the auto light switch causes the backlight to turn on for about two seconds,

whenever you position your wrist as described below in any mode.

Moving the watch to a position that is parallel to the ground and then tilting it

towards you more than 40 degrees causes the backlight to turn on.

Parallel to ground

Warning!

• Always make sure you are in a safe place whenever you are reading the

display of the watch using the auto light switch. Be especially careful when

running or engaged in any other activity that can result in accident or injury.

Also take care that sudden illumination by the auto light switch does not

surprise or distract others around you.

• When you are wearing the watch, make sure that its auto light switch is turned

off before riding on a bicycle or operating a motorcycle or any other motor

vehicle. Sudden and unintended operation of the auto light switch can create

a distraction, which can result in a traffic accident and serious personal injury.

To turn the auto light switch on and off

While the Mode Menu or Timekeeping Mode screen is on the display, hold down D

for about two seconds to toggle the auto light switch on (

not displayed).

• The auto light switch on indicator (

) is on the display in all modes while the auto

light switch is turned on.

• In order to protect against running down the battery, the auto light switch

automatically turns off approximately six hours after you turn it on. Repeat the above

procedure to turn the auto light switch back on if you want.

each key.

Auto Return Features

• If you leave the watch without performing any operation in the e-DATA MEMORY,

Telememo, or Alarm Mode for two or three minutes, or in the Calculator Mode for six

or seven minutes, it automatically changes to the Mode Menu.

• If you leave a screen with flashing digits or a cursor on the display for two or three

minutes without performing any operation, the watch automatically saves any

settings you have made up to that point and exits the setting screen.

Scrolling

The C and D buttons and the [1] and [=] keys are used in various modes and

setting screens to scroll through data on the display. In most cases, holding down

these buttons during a scroll operation scrolls at high speed.

Initial Screens

• When you enter the e-DATA MEMORY, Telememo, World Time, or Alarm Mode, the

data you were viewing when you last exited the mode appears first.

• When you enter the Timekeeping Mode from the Mode Menu, the Home City time

appears first. The information that appears in the top line of the screen is the same

type of information that was displayed when you last exited the Timekeeping Mode.

Timekeeping

• Resetting the seconds to

while the current count is in the range of 30 to 59

causes the minutes to be increased by 1. In the range of 00 to 29, the seconds are

reset to

without changing the minutes.

• The year can be set in the range of 2000 to 2099.

• The watch's built-in full automatic calendar makes allowances for different month

lengths and leap years. Once you set the date, there should be no reason to change

it except after you have the watch's battery replaced.

World Time

• The current time in all World Time Mode cities is calculated in accordance with the

Greenwich Mean Time (GMT) differential for each city, based on the current Home

City time setting in the Timekeeping Mode.

• The GMT differential is the time difference of the time zone where the city is located

from Greenwich Mean Time.

• GMT differential is calculated by this watch based on Universal Time Coordinated

(UTC) data.

Backlight Precautions

• The electro-luminescent panel that provides illumination loses power after very long

use.

• The illumination provided by the backlight may be hard to see when viewed under

direct sunlight.

• The watch may emit an audible sound whenever the display is illuminated. This is

due to vibration of the EL panel used for illumination, and does not indicate

malfunction.

• The backlight automatically turns off whenever an alarm sounds.

• Frequent use of the backlight shortens the battery life.

Auto light switch precautions

• Wearing the watch on the inside of your wrist and movement or vibration of your arm

can cause the auto light switch to activate and illuminate the display. To avoid

running down the battery, turn off the auto light switch whenever engaging in

activities that might cause frequent illumination of the display.

• The backlight may not light if the face of the watch is

more than 15 degrees above or below parallel. Make

More than 15 degrees

too high

sure that the back of your hand is parallel to the ground.

• The backlight turns off in about two seconds, even if you

keep the watch pointed towards your face.

• Static electricity or magnetic force can interfere with

proper operation of the auto light switch. If the backlight

does not light, try moving the watch back to the starting

position (parallel with the ground) and then tilt it back

toward you again. If this does not work, drop your arm

all the way down so it hangs at your side, and then bring

it back up again.

• Under certain conditions, the backlight may not light

until about one second after you turn the face of the

watch towards you. This does not necessarily indicate

malfunction of the backlight.

Battery

The indicator BATT flashes on the display any time

battery power is below a certain level. Low battery power

can cause the following conditions to occur.

• Dim, difficult-to-read display characters

• Failure of the backlight and beeper tone operations

• Inability to perform e-DATA MEMORY and Telememo

Mode operations

If battery power goes low while you are inputting e-DATA MEMORY or Telememo

data, the data you are inputting may not be saved in memory. Normal watch operation

will return after the BATT indicator disappears. If it does not disappear, have the

battery replaced.

Always leave battery replacement up to the dealer where you bought the watch

or to an authorized CASIO distributor. Be sure to show the "Attention dealer or

CASIO distributor" information to the person replacing the battery.

Indicator

If you use the backlight or any of the alarm functions a number of times during a short

period,

operations become disabled until battery power recovers.
