Basic Data: See “Inputting Basic Data”. Calorie Memory Timing

Calorie memory timing is the time of day that data measured in the Calorie Meter

Mode is stored in memory. You can specify a timing of midnight or 2:00 a.m. Select 2:00 a.m. if you perform a calorie meter operation after midnight. The initial factory default setting (which is also set when the battery is replaced) is midnight.

The Sports Calorie Meter calculates the number of calories you consume while exercising. The calculation is based on the basic data you input, the type of activity you are performing, and the duration of the activity. You can also configure the watch to store calorie values in memory, to sound an alarm to let you know when the calorie target you specify is reached, and to display the countdown to your calorie target.

• Calorie measurements are performed in the Calorie Meter Mode, which you enter by pressing C.

Before Using the Calorie Meter

• Before using the calorie meter for the first time, be sure to set your “basic data” and configure the calorie memor

y timing.

: See “To set the time and date”.

— 2 —

Page 5

• After you input your basic data and specify the calorie memory timing, you should also specify the name of activity you are performing. Calories you burn are then calculated in accordance with settings you configure. For details, see “Activities” and “Calorie Measurements”.

• Calorie Meter Mode data is stored in memory using the current Timekeeping Mode time and date. Do not change the time and date setting while a calorie measurement operation is in progress.

• See “Exercising for Optimal Health” for important information about using Sports Calorie Meter functions effectively.

Activities

For proper operation of the Calorie Meter Mode, you need to specify the name of activity you will be performing before starting a calorie measurement operation. You can specify any one of the following 43 activities.

AEROBICS AEROBICS AEROBICS BASEBALL BASKETBALL JOG JOG JOG SWIM TENNIS WALK WALK WALK TRAINING **** **** **** **** **** **** **** **** **** **** ****

• Some activities appear more than once, with the letters These letters indicate exercise load, as Low (

• The values to the right of the line of asterisks indicate exercise intensity. The larger the value, the greater the load.

• For more information about the load level for each activity, see “Activity Types and Intensities”.

Calorie Measurements

You need to start and stop the calorie measurement operation when you start and stop exercising, playing a sport, etc. The watch displays the elapsed time, number of calories burned, and the calorie target graph while a calorie measurement is in progress. The watch beeps for five seconds when the number of calories burned reaches the calorie target you preset.

• Your burned calorie value is stored in memory (as daily data) when you stop the calorie measurement operation.

• Note that the calorie measurement operation continues even if you exit the Calorie Meter Mode. If you exit the Calorie Meter Mode with data on the display while the measurement operation is stopped, the data will still be on the display when you next enter the Calorie Meter Mode. This means you can accumulate data for multiple calorie measurement operations during a single day.

• If you are engaged in an activity that has rest periods or if you perform more than one activity and want to keep track of the cumulative elapsed time and calorie totals in the Calorie Meter Mode, do not clear the display to all zeroes when you stop measurement during rest periods, etc. If you want to keep track of data for each individual session, clear the display to all zeroes each time you stop the measurement operation.

Note

• The displayed current calorie value is updated every 10 seconds.

• During measurement, the target graph shows how much progress you have made

toward achieving your target calorie level for the current date. One segment of the graph is darkened each time you burn 10% of the total target calorie amount for the day. No segments are darkened when your current calorie value is less than 10% of the target total.

• The target graph for the current date is also displayed in the Timek eeping Mode.

• You can view the calorie target countdown in the Timekeeping Mode. See “To view

Timekeeping Mode sub-screens” for more information.

• The watch performs either of the following operations whenever the calorie memory timing you specified is reached.

Backlight

Auto light switch on indicator

About the Auto Light Switch

Turning on the auto light switch causes the backlight to turn on, whenever you position your wrist as described below in any mode. Note that this watch features a “Full Auto EL Light”, so the auto light switch operates only when available light is below a certain level. It does not turn on the backlight under bright light.

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.

Wear the watch on the outside of your wrist.

•

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

•

Storing the watch for long periods in an area where there is no light or wearing it in

such a way that it is blocked from exposure to light can cause rechargeable battery power to run down. Be sure that the watch is normally exposed to bright light whenever possible

This watch employs a solar cell that converts light into electricity, which charges a

•

built-in rechargeable battery. Normally, the rechargeable battery should not need replacement, but after very long use over a number of years, the rechargeable battery may lose its ability to achieve a full charge. If you experience problems getting the rechargeable battery to a full charge, contact your dealer or CASIO distributor about having the rechargeable battery replaced.

The rechargeable battery should be replaced with a CASIO-specified CTL1616

•

battery only. Other rechargeable batteries can cause damage to the watch.

All data stored in memory is deleted, and the current time and all other settings

•

return to their initial factory defaults whenever battery power drops to Level 4 and when you have the battery replaced.

Turn on the watch’s Power Saving function and keep it in an area normally exposed

•

to bright light when storing it for long periods. This helps to keep the rechargeable battery from going dead.

Battery Power Indicator and RECOV Indicator

The battery power indicator on the display shows you the current status of the rechargeable battery’s power.

•

At Level 4, all functions are disabled and settings return to their initial factory

defaults. Functions are enabled once again after the rechargeable battery is charged, but you need to set the time and date, after the battery reaches Level 3 from Level 4. You will not be able to set any of the other settings until the battery reaches Level 2 after dropping to Level 4.

•

Display indicators reappear as soon as the battery is charged from Level 4 to Lev el 3.

•

Leaving the watch in direct sunlight or some other very strong light source can

cause the battery power indicator to temporarily show a reading that is higher than the actual battery level. The correct battery power indicator should appear after a few minutes.

•

If you use the backlight or the alarm a number of times during a short period,

RECOV appears on the display, and the backlight and beeper tone become disabled until battery power recovers. After some time, battery power will recover and RECOV will disappear, indicating that the above functions are enabled again.

•

If RECOV appears frequently, it probably means that remaining battery power is low.

Leave the watch in bright light to allow it to charge.

Charging Precautions

Certain charging conditions can cause the watch to become very hot. Avoid leaving the watch in the areas described below whenever charging its rechargeable battery. Also note that allowing the watch to become very hot can cause its liquid crystal display to black out. The appearance of the LCD should become normal again when the watch returns to a lower temperature.

Warning! Leaving the watch in bright light to charge its rechargeable battery can cause it to become quite hot. Take care when handling the watch to avoid burn injury. The watch can become particularly hot when exposed to the following conditions for long periods.

•

On the dashboard of a car parked in direct sunlight Too close to an incandescent lamp

•

Under direct sunlight

This watch is equipped with a solar cell and a rechargeable battery (secondary battery) that is charged by the electrical power produced by the solar cell. The illustration shown nearby shows how you should position the watch for charging.

Example: Orient the watch so its face is pointing at a light

source.

•

Note that charging efficiency drops when any part of the

solar cell is blocked by clothing, etc.

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 backlight automatically turns off whenever an alarm sounds.

•

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.

•

Frequent use of the backlight runs down the battery.

Auto light switch precautions

•

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

your arm can cause frequent activation of the auto light switch and illumination of 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.

•

Note that wearing the watch under your sleeve while the auto light switch is turned

on can cause frequent illumination of the display and can run down the battery.

More than 15 degrees too high

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.

You may notice a very faint clicking sound coming from the watch when it is shaken

•

back and forth. This sound is caused by mechanical operation of the auto light switch, and does not indicate a problem with the watch.

Exercising for Optimal Health

Exercises that provide optimal health benefits must be safe and allow you maintain or exceed your maximum oxygen uptake level. The type of exercise that does this best is aerobic exercise. During aerobic exercise you are able to breathe normally, so you generate energy while taking in oxygen. The body adapts so it can intake and utilize oxygen efficiently under the stress of the exercise, and so maximum oxygen uptake is increased.

Amount of Exercise Required for Good Health

The following is the amount of exercise (in terms of energy consumed) required daily for good health. Engineers, Office Staff

Men: 200 to 300kcal Women: 100 to 200kcal

Manufacturing, Sales, Service Staff

Men: 100 to 200kcal Women: About 100kcal

Exercise Duration and Frequency

Continuous Duration: At least 10 minutes of continuous exercise, which is the time

required for the body to respond aerobically to the exercise . Total Time Per Day: At least 20 minutes Frequency: Daily

Exercise Precautions

When exercising for health, harder is not necessarily better, nor is longer necessarily

•

better. In fact, overdoing exercise can even be detrimental to good health.

If you are already under the care of a physician, be sure to exercise in accordance

•

with your physician’s instructions.

Before starting any exercise program, consult a physician, even if you feel you are in

•

good health.

Exercise Intensity

The relative intensity of an exercise can be expressed in terms of the relative metabolic rate (RMR) or the metabolic equivalent (MET).

•

RMR (Relative Metabolic Rate)

The relative metabolic rate is a value that represents additional energy consumed during exercise as a multiple of basal metabolism. RMR can be calculated using the following formula. RMR =(Metabolic Energy Expenditure During Exercise) – (Metabolic Energy

Expenditure at Rest) / Basal Metabolism

MET (Metabolic Equivalent)

•

The metabolic equivalent is a value that represents energy consumed during exercise (including metabolic energy expenditure at rest) as a multiple of basal metabolic energy expenditure at rest. MET can be calculated using the following formula. MET = Metabolic Energy Expenditure During Exercise / Metabolic Energy Expenditure

at Rest

The following formula can be used to convert between MET and RMR values. MET

0.83 RMR + 1 The activity intensity values used by this watch are MET or MET values converted from RMR values.

Basal Metabolism: Minimum energy consumption required for life Metabolic Energy Expenditure at Rest: Energy expenditure when sitting quietly Metabolic Energy Expenditure During Exercise: Total energy expenditure due to
