Digital Compass Reading Precautions; Altitude Measurement; Checking The Current Altitude - Casio 5678 Operation Manual

Digital Compass Reading
Precautions
Location During Use
Taking readings near sources of strong
magnetism can cause reading error. Keep the
watch away from the following types of items.
Permanent magnets (magnetic accessories,
etc.), metal objects, high-voltage wires, aerial
wires, electrical household appliances (TVs,
computers, cellphones, etc.)
Note that correct direction readings are not
●
possible indoors, especially inside of
reinforced concrete structures.
Accurate direction readings are not
●
possible in motor vehicles, on boats, on
aircraft, etc.
Storage Location
Exposure of the watch to magnetism can
affect the accuracy of digital compass
readings. Keep the watch away from the types
of items below.
Permanent magnets (magnetic accessories,
etc.), metal objects, electrical household
appliances (TVs, computers, cellphones, etc.)
Watch Operation Guide 5678
The watch takes altitude readings and
displays results based on air pressure
measurements taken by a built-in pressure
sensor.
Important!
The altitude readings displayed by the
●
watch are relative values that are
calculated based on barometric
pressure measured by the watch's
pressure sensor. This means that
barometric pressure changes due to
weather can cause altitude readings
taken at the same location to be
different. Also note that the value
displayed by the watch may be
different from the actual elevation and/
or sea level elevation indicated for the
area where you are located. When
using the watch's altimeter while
mountain climbing, it is recommended
that you regularly calibrate its readings
in accordance with local altitude
(elevation) indications.

differences between readings
produced by the watch, and values
provided by local altitude (elevation)
indications.

Altitude
The watch takes altitude readings every
●
second for about the first three minutes.
After that, it takes readings according to
the watch's auto measurement interval
setting.
Check the information at the link below
●
to find out how to configure the auto
measurement interval.

To retrigger measurement, press (A).

To return to the Timekeeping Mode,
●
press (B).
Note
If the hour and/or minute hand is
●
located over the digital display when
you perform an altitude measurement,
the hands will temporarily shift to 4
o'clock or 8 o'clock to allow easier
reading of measurement values. The
hands will unshift to their normal
positions after about three seconds.
When you enter the Altitude Mode, the
●
second hand indicates either
timekeeping seconds, or the
differential between altitude
measurements (whichever was
indicated the last time you were in the
Altitude Mode). You can toggle
between the two second hand
functions by pressing (D).
Measurement range: -700 to 10,000
●
meters (-2,300 to 32,800 feet)
(Measurement unit: 1 meter (5 feet))
Note that calibrating altitude readings
will cause a change in the
measurement range.
[- - -] will appear for the measured value
●
if it is outside the allowable range.
