To turn an alarm and the Hourly Time Signal on and off
1. In the Alarm Mode, use E and B to select an alarm or the Hourly Time
Signal.
2. When the alarm or the Hourly Time Signal you want is selected, press C
to turn it on and off.
Indicates alarm is ON.
Indicates Hourly Time Signal is ON.
• The alarm on indicator (
) and the Hourly Time Signal on indicator
(
) are shown on the display in all modes while these functions are
turned on.
• If any alarm is on, the alarm on indicator is shown on the display in all
modes.

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.
To turn on the backlight manually
In any mode, press L to illuminate the display for about one second.
• The above operation turns on the backlight regardless of the current auto
light switch setting.
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.
• Be sure to wear the watch on the outside of your left wrist while using the
auto light switch.
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 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 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 E for about one second to toggle the
auto light switch on (
displayed) or off ( not displayed).
• The auto light switch on indicator (
) is on the display in all modes
while the auto light switch is turned on.
• In order to protect against running down the batteries, the auto light switch
automatically turns off approximately six hours after you turn it on. Repeat
the above procedure to turn the auto light switch back on if you want.
QUESTIONS & ANSWERS
Question: What causes incorrect direction readings?
Answer:
• Incorrect bidirectional calibration. Perform bidirectional calibration.
Remember that bidirectional calibration is required whenever batteries are
replaced.
• Nearby source of strong magnetism, such as a household appliance, a
large steel bridge, a steel beam, overhead wires, etc., or an attempt to
perform direction measurement on a train, boat, etc. Move away from large
metal objects and try again. Note that digital compass operation cannot be
performed inside a train, boat, etc.
Question: What causes different direction readings to produce different
results at the same location?
Answer: Magnetism generated by nearby high-tension wires are interfering
with detection of terrestrial magnetism. Move away from the high-
tension wires and try again.
Question: What does it mean when
------
------
--- appears in place of a
direction?
Answer: This is the abnormal magnetic field indicator. It means that strong
magnetism is being generated nearby. Move away from the
source of strong magnetism and try again.
Question: Why am I having problems taking direction readings indoors?
Answer: A TV, personal computer, speakers, or some other object is
interfering with terrestrial magnetism readings. Move away from
the object causing the interference or take the direction reading
outdoors. Indoor taking direction readings are particularly difficult
inside ferro-concrete structures. Remember that you will not be
able to take direction readings inside of trains, airplanes, etc.
Question: What do the numbers on the watch mean?
Answer: The face of this watch is marked with values
that increase in a counter-clockwise direction.
These values represent degrees. When you
take a direction reading, you can use these
values to find out how many degrees the 12
o’clock position of this watch (which is the
direction indicated in the digital display) differs
from magnetic north.
For example, when the Magnetic North Pointer is pointing at “90” on the
watch’s face, it means that the 12 o’clock position is 90 degrees from
magnetic north (which means that the 12 o’clock pointing due east).
Question: How does the barometer work?
Answer: Barometric pressure indicates changes in the atmosphere, and by
monitoring these changes you can predict the weather with
reasonable accuracy. Rising atmospheric pressure indicates good
weather, while falling pressure indicates deterioration weather
conditions.
The barometric pressures that you see in the newspaper and on
the TV weather report are measurements corrected to values
measured at 0 m sea level.

operation. It also contains important precautions and notes about the various
features and functions of this watch.
Auto Display Function
Auto Display function of this watch continually
changes the contents of the digital display.
Note that you cannot use any of the watch’s
other functions (except for the backlight) while
the Auto Display function is operating.
To turn the Auto Display off
Hold down D for about three seconds until
the watch beeps.
This returns to the Timekeeping Mode.
To turn the Auto Display on
Hold down D for about three seconds until the watch beeps.
• Note that the Auto Display function cannot be performed while you are
making settings.
