( Set the Altitude Alarm 1 as 129m)

Before Calibrating the Altimeter

- The altimeter's calibration procedure is designed for
use in the normal altimeter mode.

- As the altitude is calculated from the air pressure,
the change of air pressure will affect the altitude reading.

- To achieve a more accurate reading, the K2-100 needs to
be calibrated from time to time as pressure may change
gradually even within hours.

- Calibration 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 an 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. Holding down
the button changes the number at a higher speed.

- After you set the altitude, press the [mode] button to exit the
setting sequence.

- Press the [mode] button once again to return to
Altitude Graph Display.

Altitude Alarm 1 and 2

- The K2-100 has two built-in altitude alarms: Altitude
Alarm 1 and Altitude Alarm 2 that work independently.

- 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. Holding 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.

- Normal altitude is the difference between your current
altitude and SEA LEVEL. (Assuming that air pressure at
sea level is 1013.21mbar).

- Relative altitude is the difference between your
current altitude and the altitude of a specific altitude level
at which you set the altimeter to 'Zero'.

- To use relative altitude, for example, measure the
altitude difference between the starting point and the
finish points of a trek.

- To measure the altitude difference, set the K2-100 to
Relative Altitude display at the starting point of the trek,
the K2-100 will automatically set the altitude to 'Zero'.

- Check the altitude at the finish point of the trek, the
K2-100 will show the altitude difference on the
display.

Implication of the Pressure History Graph

- In general, a rise trend in the Pressure History Graph
may forecast good weat

- A steady trend in the Pressure History Graph has the
possibility to have steady weather ahead.

- A falling trend in the Pressure History Graph may
predict bad weather ahead.

IMPORTANT: To get an
forecast, the user has to stay at the same altitude for over
48 hours.

Before Calibrate the Barometer

- The K2-100 was calibrated for you in the factory. For normal
use, you need not to calibrate the Barometer. But for vigorous
users, a calibration procedure has been build in the K2-100.

- Before calibrate the Barometer, you must have the
ambient barometric pressure, because that pressure value
has to be input into the K2-100 during the calibration
procedure.

- You may call up the observatory station at the nearest
location from your current position to get the ambient
barometric pressure.

Important: Inputing an incorrect pressure in the calibration
procedure will result in a mistaken pressure reading in the future.

Pressure Calibration Procedures

- Press and hold the [adjust] button for 2 seconds to change
the display from the Pressure Graph Display to Barometric
Pressure Calibration Display.

- The digits of the middle row of the display and the barometric
pressure unit start flashing because it is selected.

- Press the [start/stop] button to increase the number; press
the [lap/reset] button to decrease the number. Hold down the
button to change the number at a higher speed.

- If you select a wrong barometric pressure unintentionally,
press and hold the [adjust] button for 3 seconds to restore
the setting to the absolute pressure value.

- After you set the barometric pressure, press the [mode]
button to exit the setting and return to Barometric Pressure
Graph Display.

- If no button is pressed in the setting display for about 3
minutes, the K2-100 will return to the Barometric Pressure
