GEOS 11 DEMONSTRATION
This is a basic demonstration of the button sequence of the GEOS 11 in normal mode (no special screens activated). The instrument itself first needs to be started by pressing and holding the SEL button for two seconds.

Demo:
1) Press the SEL button to highlight a line on the LCD
2) Press the MOD button to change the information viewed on that line while flashing

Modes Available:

First Line:
- maximum windspeed
- average windspeed

Second Line:
- Change windspeed units (on actual instrument, you must press and hold the MOD button to change these units)

Third Line:
- Temperature
- Minimum Temperature
- Maximum Temperature
- Windchill or Heat Index (depending on measured temperature range)
- Minimum Windchill
- Maximum Windchill
- Relative Humidity
- Minimum Relative Humidity
- Maximum Windchill
- Dew Point

Fourth Line:
- Altitude
- Maximum Altitude
- QNH
- QFE
- Absolute Air Pressure
- Flight Level
- Digital Compass

*Response time for temperature and humidity is highly dependant of the air flow over the exposed sensors. With air flow, response time is within a few seconds to adjust to the ambient temperature and relative humidity. With no air flow, several minutes may be required to adjust properly.

Operating Temperature:
Normal operating temperature: -10°C to +70 °C (14°F to 158°F)
Reading of display still possible: -20°C to -10°C (-4°F to 14°F)
Slow reading of display, but instrument still working: -40°C to -20°C (-40°F to -4°F)

Power:
Instrument: 1 button lithium battery 3V CR2032
LED Light: 2 button lithium batteries 3V CR2032
INCLUDED: 4 button lithium batteries 3V CR2032 (1 spare for instrument, 1 spare for LED light)
