the change of air pressure w
ill
affect the altitude reading.
- To achieve a more accurate reading, the
K2-100
need
s
to
be calibrated from time to time as pressure may change
gradually even within hours.
- Calibrat
ion of
the
K2-100
must occur at
a known
altitude,
such as at sea level or beside an altitude sign pole,
as
that altitude value has to be
entered into
the
K2-100
during the
calibration procedure.
Important:
Entering
a
n
incorrect altitude in the calibration
procedure
will
result
in
a
mistaken altitude in
the
future.
Altitude Calibration Procedures
-
Press and hold the [adjust] button for 2 seconds to enter the
Altitude Calibration Display.
-
Press the [adjust] button once again to enter the calibration
sequence, the digits of the middle row of the display and the
altitude unit will start flashing.
-
Press the [start/stop] button to increase the number; press
the [lap/reset] button to decrease the number. Hold
ing
down
the
button changes the number at a higher speed.
-
After you set the altitude, press the [mode] button to exit the
setting sequence.

Altitude Alarm 1 and 2
- The
K2-100
has two
built-in altitude alarms: Altitude
Alarm 1
and Altitude Alarm 2
t
h
at
work independent
ly
.
- The Alarm icon will flash and the
K2-100
will sound for 10
seconds when you pass through the Altitude Alarm Limit,
either below or above the limit.
-
When the alarm sounds, press any button to stop the alarm.
- The Altitude Alarms can be set within the range from
-30065ft to 30065 ft (-9164m
to 9164m
)
.
-
If two Altitude Alarms are set at the same altitude limit value,
the Altitude Alarm 1 will be activated only.
To Set the Altitude Alarm Limit and set the Alarm 1 ON/OFF
-
Press and hold the [adjust] button for 2 seconds to enter
Altitude Calibration Display. Press the [adjust] button once
again to select the Altitude Alarm 1 Display
.
-
Press and hold the [adjust] button to enter the Altitude Alarm
Setting Display. In the setting display, the altitude digits and
the altitude unit will flash. Press the [start/stop] button to
increase the altitude number; press the [lap/reset] button to
decrease altitude number. Hold
ing
down the button
changes
the altitude
at a higher speed.
-
Once you change the altitude alarm, the Altitude Alarm
1 turn ON automatically. After you set the altitude alarm,
press the [mode] button to exit the setting sequence.
-
Press the [lap/reset] button to turn the alarm ON or OFF.
-
Press the [mode] button once again to return to the Altitude
History Graph Display. A dotted line will show on the display
to illustrate the Alarm 1's limit.
To Set the Altitude Alarm 2
-
Set the Altitude Alarm 2 in the same manner as setting
Altitude Alarm 1.

-
The Altitude History Graph of the Altitude Graph Display
is plotted by these historical altitude values.
-
The X-axis of the history graph is time variable; the Y-
axis of the history graph is altitude variable. The Altitude
History Graph makes up 11 rows and 40 columns.
-
The memory on the left hand side of the history graph
is
recorded early than those on the right.
-
The scale of the Y-axis of the history graph is changeable,
the scale will be changed in order to fit in the altitude
values. Check the 'Altitude History Graph Scale' section
for more detail on the scale of the history graph.
To Switch among Units
- The
K2-100
can display altitude in meter (m) or feet (ft);
the
K2-100
can display temperature in Celsius (
C
) or
Fahrenheit ( F).
-
Press and hold the [lap/reset] button to change the units
as in the units select sequence.
Altitude History Graph Scale
-
The scale of the Y-axis of the History Graph is varied
for fitting all the altitude memory into the graph.
-
Press the [lap/reset] button once to view the altitude
scale information, in the Altitude Graph Display,
-
The '
GRAPH SCALE
' message will slide out and display
for 3 seconds, then the X-axis and Y-axis resolutions
will be shown.
-
For example, '
