Exercise Stopwatch

Minutes Seconds

Hours

1/100 second Timekeeping Mode time

The exercise stopwatch is a 1/100-secondstopwatch that measures elapsed time, split time, and two finishes. The exercise stopwatch uses the data you input in the Basic Data Input Mode and a pacer signal to calculate the number of calories you burn and the distance you cover while jogging or running.

The stopwatch measurement operation continues even if you exit the Exercise Stopwatch Mode.

Exiting the Exercise Stopwatch Mode while a split time is frozen on the display clears the split time and returns to elapsed time measurement.

Stopwatch measurements are performed in the Exercise Stopwatch Mode, which you enter by pressing C.

How the Exercise Stopwatch Works

There are two ways you can use the exercise stopwatch: to measure elapsed time like a standard stopwatch (see “To measure times with the stopwatch”), and to keep track of the number of calories you burn or the distance you cover while jogging or running. In order to use the exercise stopwatch to keep track of calories and distance, you must first perform the steps listed below.

1.Set your basic data. See “Inputting Basic Data”.

2.Configure the pacer signal. See “About the Pacer Signal”.

Note

In order to obtain accurate calorie and distance calculations, you must set accurate basic data and keep your exercise pace in accordance with the pacer signal emitted by the watch.

Whenever you clear the stopwatch to all zeros, all exercise stopwatch data (elapsed time, distance, calories burned, recording date) is recorded automatically in the watch’s memory. See “Recall Mode” for more information.

The unit of measurement used for the distance calculation depends on the unit you select for your stride length as shown in the table below. See “To input your basic data” for more information.

Note

Whenever the elapsed time reaches 10 hours, the contents of the display change from hours, minutes, seconds, and 1/100-secondto hours, minutes, and seconds only.

Pressing B while an elapsed time or split time operation is in progress, or while timing is stopped, causes the upper part of the display to toggle between calories burned and distance covered.

If you set a target calorie value in the Basic Data Input Mode, the watch beeps and the TARGET indicator flashes on the display to let you know when the target value is reached.

If you have red or blue selected for the current time in the Timekeeping Mode, pressing A during an elapsed time operation causes the split time to appear on the display in red.

If you have red or blue selected for the current time in the Timekeeping Mode, the elapsed time changes to blue after you reach your target calorie value.

The current calories count is updated at 30-secondintervals.

About the Pacer Signal

The pacer signal of this watch beeps in accordance with a pacer value (rate) set by you. You can use the pacer signal to maintain a constant pace while jogging or running. You can also turn off the pacer signal when you do not want to use it.

The pacer value you set specifies the number of beeps per minute.

Turning on the pacer signal causes the watch to beep at the rate specified by the pacer value.

You can disable the pacer function by setting a pacer value of xxx. While the pacer value is set toxxx, the watch does not calculate calories burned and distance covered, so both values are indicated as zero on the display.

About Memory Management

This watch has enough memory to store 30 exercise records. Each exercise record includes the following entries: elapsed time, distance covered, calories burned, and recording date. In addition, the watch also stores the cumulative total distance and cumulative calories burned each time you perform a stopwatch operation.

Exercise records are arranged in the order they are recorded.

When exercise record memory becomes full, performing another Exercise Stopwatch Mode operation causes the oldest exercise record in memory to be deleted to make room for the new record.

To recall exercise records

In the Recall Mode, use A and D to scroll through exercise records.

The upper part of an exercise record screen alternates between the calories burned and distance covered values.

A TARGET indicator is displayed on any record where the total number of calories you burned exceeds the target calorie value.

To delete an exercise record

1.In the Recall Mode, display the record you want to delete.

2.Hold down B until the watch emits a long beep (and until cmr stops flashing on the display).

Performing step 2 while the Cumulative Total screen is on the display resets the calorie and distance cumulative totals to zero. After that, new cumulative totals will be started from the next Exercise Stopwatch Mode operation.

Deleting a record does not change the cumulative total values.

Inputting Basic Data

Stride length

Stride Length screen

You can use the Basic Data Input Mode to input your stride length, weight, age, and target calorie value. The Exercise Stopwatch Mode uses the basic data you input for calculating distance covered and the number of calories burned while jogging or running.

All of the operations in this section are performed in the Basic Data Input Mode, which you enter by pressing C.

Basic Data

The term “basic data” refers to information about your stride length, current weight, and age, and your target calorie setting.

Be sure to update basic data values whenever the person using the watch changes.

Stride Length

You can specify either inches (in) or centimeters (cm) as the stride length unit. The unit you specify for the stride length unit also determines the unit of measurement used for the distance value in the Exercise Stopwatch Mode and Recall Mode, as shown below.

In any mode, press L to illuminate the display for about one second.

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 one second, 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

More than 40 °

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

In the Timekeeping Mode, hold down A for about two seconds to toggle the auto light switch on ( displayed) and off (not displayed).

The auto light switch on indicator ( ) is on the display in all modes while the auto light switch is turned on.

Reference

This section contains more detailed and technical information about watch operation. It also contains important precautions and notes about the various features and functions of this watch.

Auto Display

Auto Display continually changes the contents of the digital display.

To turn off Auto Display

Press any button (except for L) to turn off Auto Display.

To turn on Auto Display

Hold down C for about two seconds until the watch beeps.

Note that Auto Display cannot be performed while a setting screen is on the display.

Auto Return Features

After you perform any button operation in any mode (except for the Stopwatch Mode), pressing C returns directly to the Timekeeping Mode.

If you leave a screen with flashing digits 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.

Data and Setting Scrolling

The A and D buttons 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 through the data at high speed.

Initial Screens

When you enter the Basic Data Input Mode, the data you were viewing when you last exited the mode appears first.

Timekeeping

With the 12-hourformat, theP (PM) indicator appears on the display for times in the range of noon to 11:59 p.m. and theA (AM) indicator appears for times in the range of midnight to 11:59 a.m.

With the 24-hourformat, times are displayed in the range of 0:00 to 23:59, without any indicator.

The year can be set in the range of 2000 to 2039.

The watch’s built-infull automatic calendar automatically 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.

The current time is displayed in the lower part of the Exercise Stopwatch, Countdown Timer, Alarm, and Dual Time screens. On these screens, the a.m. and p.m. indicators are not shown when the watch is configured for the 12-hourtimekeeping format.

Exercise Stopwatch

Animation area

An animated figure appears in the animation area while

a stopwatch operation is in progress, even if you change

 

 

to another mode.

 

 

The values for the number of calories burned produced

 

 

by this watch include both calories normally burned

 

 

through normal metabolism and rest and extra calories

 

 

burned by jogging or running.

 

 

This watch is set up to calculate calories burned by men

 

 

while jogging. Women should decrease the values

 

 

produced by this watch by 5%.

Backlight Precautions

The electro-luminescentpanel 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

In order to protect against running down the battery, the auto light switch automatically turns off approximately five hours after you turn it on.

Avoid wearing the watch on the inside of your wrist. Doing so causes the auto light switch to operate when it is not needed, which shortens battery life. If you want to wear the watch on the inside of your wrist, turn off the auto light switch feature.

More than 15 degrees

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

too high

more than 15 degrees above or below parallel. Make

 

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

 

The backlight turns off in about one second, 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

3

malfunction of the backlight.
