will remain illuminated for about one second or three seconds,
depending on the current illumination duration setting.
•
The above operation turns on illumination regardless of the current
auto light switch setting.
•
Illumination is disabled during time calibration signal reception, while
confi guring sensor measurement mode settings, and during bearing
sensor calibration.
To change the illumination duration

About the Auto Light Switch
Turning on the auto light switch causes illumination to turn on,
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
illumination to turn on.
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 startle 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 traffi c accident
and serious personal injury.
Note
•
This watch features a “Full Auto EL Light”, so the auto light switch operates only when available light is
below a certain level. It does not illuminate the display under bright light.
•
The auto light switch is always disabled, regardless of its on/off setting, when any one of the following
conditions exists.
While an alarm is sounding
During sensor measurement
While a bearing sensor calibration operation is being performed in the Digital Compass Mode
While a receive operation is in progress in the Receive Mode

To turn the auto light switch on and off
In the Timekeeping Mode, hold down
L
for about three seconds to toggle
the auto light switch on (
A.EL
displayed) and off (
A
.
EL
not displayed).
•
The auto light switch on indicator (

) is on the display in all modes
while the auto light switch is turned on.
•
The auto light switch turns off automatically whenever battery power
drops to Level 4.
Illumination Precautions
•
Frequent display illumination can run down the battery quickly and require charging.
The following guidelines give an idea of the charging time required to recover from a single illumination
operation.
Approximately fi ve minutes exposure to bright sunlight coming in through a window
Approximately 50 minutes exposure to indoor fl uorescent lighting
•
The electro-luminescent panel that provides illumination loses power after very long use.
•
Illumination may be hard to see when viewed under direct sunlight.
•
Illumination turns off automatically whenever an alarm sounds.
•
Frequent use of illumination 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.
•
Illumination may not turn on 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.
•
Illumination turns off after the preset illumination duration, 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 illumination does not turn on, try moving the watch back to the
starting position (parallel with the ground) and then tilt it back towards your face
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.
•
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.
Button Operation Tone
The button operation tone sounds any time you press one of the watch’s buttons. You can turn the button
operation tone on or off as desired.
•
Even if you turn off the button operation tone, the alarm, Hourly Time Signal, and Countdown Timer
Mode alarm all operate normally.
To turn the button operation tone on and off
1. In the Timekeeping Mode, hold down
E
until the currently selected
city code starts to fl ash. This is the city code setting screen.
•
Before the city code starts to fl ash, the message
SET Hold
will appear on the display. Keep
E
depressed until
SET Hold
disappears and the city code starts to fl ash.
2. Keep pressing
D
until
MUTE
or
KEY
is displayed in the upper left
corner of the display.
•
See step 3 under “To change the current time and date settings
manually” for information about how to scroll through setting
screens.
3. Press
A
to toggle the button operation tone on (
KEY
) and off (
MUTE
).
4. After the settings are the way you want, press
E
twice to exit the
setting screen.
Note
•
The mute indicator is displayed in all modes when the button
operation tone is turned off.
Troubleshooting
Time Setting
See “Radio Controlled Atomic Timekeeping” for information about adjusting the time setting according to a
time calibration signal.
■
The current time setting is off by hours.
Your Home City setting may be wrong. Check your Home City setting and correct it, if necessary.
■
The current time setting is off by one hour.
If you are using the watch in an area where time calibration signal reception is possible, see “To confi gure
Home City settings”.
If you are using in the watch in an area where time calibration signal reception is not possible, you may
need to change your Home City’s standard time/daylight saving time (DST) setting manually. Use the
procedure under “To change the current time and date settings manually” to change the standard time/
daylight saving time (DST) setting.
Sensor modes
■
I can’t change the temperature, barometric pressure, and altitude units.
When
TYO
(Tokyo) is selected as the Home City, the altitude unit is set automatically to meters (m), the
barometric pressure unit to hectopascals (hPa), and the temperature unit to Celsius (°C). These settings
cannot be changed.
■
“ERR” appears on the display while I am using a sensor .
Subjecting the watch to strong impact can cause sensor malfunction or improper contact of internal
circuitry. When this happens,
ERR
(error) will appear on the display and sensor operations will be disabled.

If
ERR
appears while a measurement operation is being performed in a sensor mode, restart the measurement.
If

appears on the display again, it can mean there is something wrong with the sensor.
