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 � 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 after the preset display illumination duration (see �To set the time and date�), 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. � 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 activity

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.

Timekeeping
� Resetting the seconds to 00 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 00 without changing the minutes. � 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 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 when battery power drops to Level 4.

Auto Return Features
If you leave a screen with flashing digits on the display for two or three minutes without performing any operation, the watch automatically exits the setting screen.

Scrolling
The E and A 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.

Power Saving Function
When turned on, the Power Saving function automatically puts the watch into a sleep state whenever it is left for a certain period in an area where it is dark. The table below shows how watch functions are affected by the Power Saving function. Elapsed Time in Dark Display Operation Display is off, but all functions are enabled. All functions are disabled, but timekeeping is maintained.

60 to 70 minutes Blank, with SLEEP flashing 6 or 7 days Blank, with SLEEP not flashing

� Wearing the watch inside the sleeve of clothing can cause it to enter the sleep state. � The watch will not enter the sleep state while the Timekeeping Mode time is between 6:00 AM and 9:59 PM. If the watch is already in the sleep state when the time reaches 6:00 AM, however, it will remain in the sleep state. � The watch will not enter the sleep state while it is in the Calorie Meter Mode or Stopwatch Mode.

To recover from the sleep state Perform any one of the following operations. � Move the watch to a well-lit area.
