ALTIMETER AND BAROMETER
After battery inserted, the device will automatically measure the barometer readings
as well as the maximum sea level pressure reading.
(1) To Set and Reset Altimeter:
Altimeter: measures in either meters or feet, range:-400 ~ 9000 meters. The device
provide both current altitude and maximum altitude
(ⅰ) Current Altitude display
(ⅱ) Maximum Altitude display (“MAX” icon display on the LCD)
Press “ALT”button to enter altimeter mode. Press “ALT” button again to display
the maximum altitude.
When LCD display current altitude, press and hold “ALT” button for 3 seconds to
enter setting. Press “▼”or “▲”to adjust altitude, and press “MODE” button to
confirm and quite the setting. Press “▼”and “▲” at the same time, current
altitude value will be reset to 0.
When LCD display maximum altitude, press “▼”and “▲” at the same time,
maximum altitude record will be cleared, and reset to 0.

(2) To Set Sea Level Pressure and Weather Forecast Icons
(ⅰ) Current barometric pressure:
(ⅱ) Sea level pressure (“SEA” icon display on the LCD)
Press “BARO” button to enter Barometer mode, LCD will display the current
barometric pressure, press “BARO” button again to display the sea level
pressure.
In Sea Level pressure display, hold “BARO” button for 3 seconds to enter setting.
Press “▼”or “▲”to change setting, and press “MODE” button to confirm and
move to next setting.
The setting sequences are as follow: sea level pressure, toggle weather forecast
icons. (Weather Forecast have four animation as below)
.
The weather forecast will start the first forecast at 6 hours later after the current
weather status is entered.
Note:
(1) Barometric pressure and sea level pressure measurement in hpa, mmHG or inHG.
When sea level pressure is changed, the altitude will adjust itself accordingly.
(2) The range of sea leave pressure is 900mbar ~1100mbar.
(3)

COMPASS
The compass shows the bearing in degrees due North together with 16 cardinal
points
Press COMPASS button, the unit will enter Compass mode, Hold the unit
horizontal. Point the 12 o’clock position of the unit in the direction you want to
measure. As below graph shown, the direction you are measuring now is WSW
223°.The arrow “▲” always point to North.
When the direction of compass is point to North (degree for -12.5 to +12.5), the
direction icon outside will be shown. If no key press for 30 seconds, the unit will
auto off the compass and return to temperature mode.
Note:
1. The compass must be kept in a level position when in use. Taking a measurement
while the unit is not horizontal (in relation to the horizon) can result in large
measurement error
2. Always take bearings in the open air, because it is easily affected by disturbing
sources of magnetism.

(1) Compass Sensor Calibration
The compass should be calibrated before use OR when the battery is replaced.
In COMPASS mode, hold “COMPASS”button for 3 seconds to enter the compass
sensor calibration mode, press COMPASS button to start the calibration
Keep the unit in a level position or on top of a non-metallic table/desk, reference
to the arrow showing in LCD, rotate the compass clockwise for one full rotation
slowly.

When finished, LCD will display “OK” if the calibration is successful or display
“Fail” if it is failed as below.
(2) Set the Declination Angle
The angle between magnetic north and the true north direction is called magnetic
declination. The earth’s magnetic poles fluctuate over time, and it also varies from
place to place. Finding the declination on the map or website, then set the
declination on this unit to offset the difference between magnetic north and true
north. Please note that if you fail to do this, the readings you get from the compass
could be in error.
In COMPASS mode, hold “COMPASS”button for 3 seconds to enter the compass
sensor calibration mode, press “MODE” button to enter setting of declination
angle. The angle would flash on the LCD. (for example, as below, “ 0° ” will flash
on the LCD)

Press “▼”or “▲”to change the angle value, range from -90°to 90°, and press
“MODE” button to confirm and exit the setting.
TEMPERATURE
When compass mode is off, the top 2 row LCD display will provide the reading of
temperature with unit of °C or °F, the range from -20°C to 60°C.
When Temperature is lower than -20°C, LCD display will show LL.L°C. When
temperature is higher than 60°C, LCD display will show HH.H°C.
BACKLIGHT/ KEYPAD LOCK
Press LIGHT button to turn backlight on for 5 seconds.
Press and hold LIGHT button for 3 seconds, keyboard will be locked and icon
will be shown in LCD display. Hold the LIGHT button for 3 seconds to unlock the
keyboard.
TURN OFF UNIT
Hold the “▼”& “▲” button at the same time, and use a pin to press “reset”
button to turn off the unit. The LCD display and all the function will be off.
Press and hold “LOCK” & “COMPASS” button to restart the unit,
After the unit been turned off, all the record and setting data would be cleared.
