ABOUT THIS USER’S GUIDE

BACKLIGHT

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.

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 light.

Warning!

• Never try to read your watch when mountain climbing or hiking in areas that

are dark or in areas with poor footing. Doing so is dangerous and can result in serious personal injury.

• Never try to read your watch when running where there is danger of acci-

dents, especially in locations where there might be vehicular or pedestrian traffic. Doing so is dangerous and can result in serious personal injury.

• Never try to read your watch when riding on a bicycle or when operating a

motorcycle or any other motor vehicle. Doing so is dangerous and can result in a traffic accident and serious personal injury.

• 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.

How the Watch Counts Calories

• The watch calculates the number of calories you consume using the elapsed time measured in the Exercise Stopwatch Mode and the age, weight and other data you input in the Basic Data Input Mode. The calorie calculations made by this watch will not be correct unless you input your own personal basic data.

• The watch also sounds a pacer signal to that you should use as a reference to control the intensity of your workouts. See “About the Pacer Signal” for details.

• The calorie value on the display is updated every 30 seconds while a stopwatch operation is in progress.

About Auto-Repeat

All of the timers for which Auto-Repeat is turned on operate in succession when a timer operation is started. This means you can set up an interval routine that is tailored to your own specific training needs.

• The following example shows how timing would be performed when Auto-Repeat is turned on for Timers 2, 4, and 5. This loop would be repeated endlessly until you stop it.

• If Auto-Repeat is turned on for only one timer, that timer’s operation is repeated until you stop it.

• The watch beeps for two seconds when the end of a countdown is reached while Auto-Repeat is turned on.

Data and Setting Scrolling

The

A and

C buttons are used in various modes and 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.

12-hour/24-hour Timekeeping Formats

The 12-hour/24-hour timekeeping format you select in the Timekeeping Mode is also applied in the Alarm Mode.

Timekeeping Mode Notes

• In the Timekeeping Mode (except when making setting), press tween the 12-hour and 24-hour formats.

• With the 12-hour format, the P (PM) indicator appears to the left of the hour digits for times in the range of noon to 11:59 pm and the A (AM) indicator appears to the left of the hour digits for times in the range of midnight to 11:59 am.

• With the 24-hour format, times are indicated in the range of 00:00 to 23:59, without any indicator.

• The year can be set in the range of 1995 to 2039.

• The watch’s built-in full automatic calendar automatically make allowances for dif-

ferent month lengths and leap years. Once you set the date, there should be no reason to change it except after the replacement of the watch’s battery.

Backlight Precautions

• The electro-luminescent (EL) panel loses illuminating power after very long use.

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

direct sunlight.

• The watch will emit an audible sound whenever the display is illuminated. It does not indicate malfunction of the watch.

• The backlight automatically turns off whenever an alarm sounds.

• Normally the backlight lights when you press the

watch Mode, pressing second.

The animation area of the display shows animated figures when you preform certain button operations.

• In the Timekeeping Mode, the animation area normally shows the day of the week. Different animated figures appear at 00, 20, and 40 seconds.

Auto light switch precautions

• 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.

• The backlight turns off in about one second, even if you keep the watch pointed towards your face.

• The backlight may not light if the face of the watch is more than 15 degrees off the parallel as shown below. Make sure that the back of your hand is parallel to the ground.

Parallel to ground

• 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 or less after turn the face of the watch towards you. This does not necessarily indicate malfunction of the backlight.

Exercise Stopwatch Mode Precautions

• 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 women while jogging. Men should increase the values produced by this watch by 5%.

• You can use the 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.

• Whenever a lap time or split time is on the display in the Exercise Stopwatch Mode, the graphic area shows the difference between the current and last lap.

Animation area

• While the stopwatch is running, the animation are shows either a pig ( ), a leopard (

Exercise Stopwatch Mode memory management

• Measuring time with the stopwatch causes the date, elapsed time, and calories burned to be stored under a run number. If you measured lap and split times, they are also stored, along with a best lap time.

• This watch has enough memory to store up to 60 records. Date, run number, and calories burned take up one record. Each time (elapsed time, lap time, split time, best lap) takes up one record. The following shows some examples of how memory can be used, but other combinations are also possible.

(plus date, run number, calories, best time)

• When memory becomes full, the next stopwatch measurement operation automatically deletes the oldest record number to make room for the new data. Note that data is deleted in record number units, so all split/lap times under the run number are deleted.

• The lap/split number flashes on the display when an ongoing stopwatch operation causes memory to become full.

Basic Data

The term age, and stride length.

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

Pacer Value

The speed of the pacer signal is determined by the pacer value, which is the number of beats per minute. You can set the pacer value in increments of 5, in the range of 100 to 200.

Age

You can set the age value in 1-year increments in the range from 13 to 19 years. In the range from 20 to 70, you can set the age value in 10-year increments.

Weight

You can set your current weight value in increments of 1 kg, in the range of 30 to 150 kg. Those lighter than 30 kg should use the minimum setting, while those heavier than 150 kg should use the maximum setting.

Stride Length

You can set stride length values in increment of 5 cm, in the range of 40 to 190 cm. The following examples illustrate how you can calculate values for these setting.

• 239 steps required to jog around a 300-meter track. 300 (meters)
