Battery Power Indicator

The battery power indicator on the display shows you the current status of the

rechargeable battery's power.

Battery power indicator

Battery Power

Level

Indicator

(Charge Soon Alert)

The flashing

indicator at Level 4 tells you that battery power is very low, and that

exposure to bright light for charging is required as soon as possible.

At Level 5, 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 current time, date, and all other settings after the

battery is recharged to Level 3 from Level 5. Though the time appears on the display

after the battery is charged to Level 4, you will not be able to change the time setting

until the battery reaches Level 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 any of the alarm functions a number of times during a

short period, RECOVER appears on the display and the following operations

become disabled until battery power recovers.

Backlight

Beeper tone

After some time, battery power will recover and RECOVER will disappear, indicating

that the above functions are enabled again.

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

Charging Guide

After a full charge, timekeeping remains enabled for up to about nine months, while

the watch is used under the conditions described below.

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.

Power Saving Function

When turned on, the Power Saving function automatically

puts the watch into a sleep state whenever it is left in an

area where it is dark for 30 to 35 minutes. The sleep state

is indicated by a blank screen with SLEEP flashing on it.

In the sleep state, all functions are enabled, except for the

display.

Wearing watch inside the sleeve of clothing can cause it

to enter the sleep state.

To recover from the sleep state

Perform any one of the following operations.

Move the watch to a well-lit area. It can take up to five seconds for the display to turn

on.

Press any button.

Angle the watch towards your face for reading.

To turn Power Saving on and off

1. In the Timekeeping Mode, hold down B until the

seconds start to flash, which indicates the setting

screen.

2. Press C seven times until the Power Saving on/off

screen appears.

3. Press D to toggle Power Saving on (ON) and off

(OFF).

4. Press B to exit the setting screen.

The Power Saving on indicator (SAVE) is on the display

in all modes while the Power Saving is turned on.

Auto Return Feature

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.

Initial Screens

When you enter the Alarm Mode, the screen you were viewing when you last exited

the mode appears first.

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

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 no 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 when battery power drops to Level 5.

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 or 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.

Number of Logs

Memory Capacity

Currently in Memory

61 Records

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 records to be deleted automatically to make room for new records.

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
