ALARM FUNCTIONS
Five independent daily alarms can be set.
Each alarm lets you set the hour and
minutes. When the Daily Alarm is on, the
alarm sounds for 20 seconds at the preset
time each day. Press any button to stop the
alarm after it starts to sound.
When the Hourly Time Signal is on, the
watch beeps every hour on the hour.
•
The segments in the graphic display
create a rotational movement effect while
an alarm is sounding.
To set alarms
1. Use
C
to enter the Alarm Mode.
2. Press
D
to select Alarm 1 through 5.

3. After you select an alarm, hold down
A
until the hour digits flash on the
display. The hour digits flash because they are
selected.
•
At this time, the alarm is automatically switched on.
4. Press
C
to change the selection in the following sequence.

5. Press
D
to increase the selected digits and
B
to decrease them.
Holding down either button changes the selection at high speed.
•
The format (12-hour or 24-hour) of the alarm time matches the format you
selected for normal timekeeping.
•
When setting the alarm time using the 12-hour format, take care to set
the time correctly as morning (no indicator) or afternoon (P).
6. After you set the alarm, press
A
to return to the Alarm Mode.
To switch an alarm or the Hourly Time Signal on and off
1. In the Alarm Mode, press
D
to select an alarm or the Hourly Time Signal.
2. When the alarm or Hourly Time Signal you want to is selected, press
B
to switch it on and off.
A
Indicates alarm is ON.
S
Indicates Hourly Time Signal is ON.
•
If any alarm is on, the alarm on indicator (
A
) is shown on the display
when you change to another mode.

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 Digital Compass operation 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 the Digital Compass to produce
different readings at the same location?
Answer:
•
Direction being measured is somewhere between two measurable
directions (N and NNW, for example). The Digital Compass is designed
to indicate any one of 16 different directions. If you move the 12 o’clock
position slightly to the left or right (to move it off of the point between
the two measurable directions), the Digital Compass should consistently
produce the same reading.
•
Magnetism generated by nearby high-tension wires are interfering with
reception 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 performing Digital
Compass operations indoors?
Answer: TV, personal computer, speakers, or some other object is
interfering with terrestrial magnetism. Move away from the object
causing the interference or perform the Digital Compass operation
outdoors. Indoor Digital Compass operations are particularly difficult
inside ferroconcrete structures. Remember that you cannot perform
Digital Compass operations inside of trains, airplanes, etc.
Question: How does the altimeter work?
Answer: Generally, atmospheric pressure and temperature decrease
as altitude increases. This watch is equipped with a pressure sensor
and bases its altitude measurements on International Standard
Atmosphere (ISA) values stipulated by the International Civil Aviation
Organization (ICAO), which define relationships between altitude,
atmospheric pressure, and temperature.
There are two standard methods of expressing altitude: Absolute altitude
and Relative altitude. Absolute altitude expresses an absolute height above
sea level. Relative altitude expresses the difference between the height of
two different places.

Example:
To obtain readings that are close to absolute altitude.
When you are out hiking or mountain climbing, calibrate the altimeter using
an altitude value from another source (a signpost or map, for example). Do
this just before you start your altitude measurements.
1. At Point A, calibrate the altimeter to 400
meters.
2. Proceed from Point A to Point B, taking
altimeter measurements along the way.
•
If you also have altitude data for Point B,
you should again calibrate the altimeter
there.
•
Be sure to recalibrate at Point B if changing weather conditions produce
altitude reading errors.
•
The following conditions will prevent you from obtaining accurate readings:
Atmospheric pressure changes because of changes in the weather
Extreme temperature changes
