How the Stopwatch Works

There are two ways you can use the stopwatch: to measure elapsed time and

lap/split times like a standard stopwatch (see "To measure times with the

stopwatch"), and to keep track of the distance you cover while jogging or

running. In order to use the stopwatch to keep track of 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 distance calculations, you must set accurate basic

data and keep your exercise pace in accordance with the pacer signal

emitted by the watch.

display format changes to show hours, minutes, and seconds.

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 to xxx, the watch does not calculate distance

covered.

To set the pacer value

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 (

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.

Timekeeping

· With the 12-hour format, the

P (PM) indicator appears on the display for

times in the range of noon to 11:59 p.m. and the A (AM) indicator appears for

times in the range of midnight to 11:59 a.m.

· With the 24-hour format, 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-in full 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 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-hour timekeeping format.

Stopwatch

· You can use lap time measurement to time how long it takes to complete a

specific portion (such as a single lap) of a race.

· You can use split time measurement to time how long it takes to get from the

start to a specific point in a race.

Memory Management

Each time you press A to start a new elapsed time, lap/split operation in the

Stopwatch Mode, the watch automatically creates a new "log" in its memory.

The log remains open for data storage until you permanently close it by

pressing D to clear the stopwatch to all zeros.

· The watch has enough memory to hold up to 61 records. Since each log title

screen uses up one record of memory space, the maximum number of lap/

split time records you can store depends on how many logs there are

currently in memory, as shown below.

Memory Capacity

61 Records

Number of

Logs Currently in

Memory

Lap/Split Time Record Capacity

61 records 1 log title screen = 60

61 records 2 log title screens = 59

61 records 5 log title screens = 56

· The watch also calculates the cumulative total distance for all stopwatch

operations since the last time the cumulative total distance was reset. The

cumulative total does not affect memory capacity.

· If watch memory is already full when you perform a stopwatch button

operation that creates a new log, the oldest log in memory and all of its

records are deleted automatically to make room for the new log.

· If you are adding records to the only log in memory and watch memory becomes

full, adding another record causes the oldest record in the log to be deleted

automatically to make room for the new record.

· If you are adding records to a log when there are multiple logs in memory and watch

memory becomes full, adding another record causes the oldest log in memory and

all of its record to be deleted automatically to make room for new records.

How Stopwatch Data is Stored

The following table describes how data is stored when you perform the various

button operations described.

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

· 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.

Daily Alarm Operation

The alarm sounds at the preset time each day for about 20 seconds, or until

you stop it by pressing any button.

To test the alarm

In the Alarm Mode, hold down A to sound the alarm.

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.

More than 15 degrees

too high

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

is 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

Parallel to ground
