Battery shows the actual battery voltage. The upper segments of the 

display will only indicate while charging, after which a full charge is 

indicated with around 80% of the segments showing, which is around 

4 volts. “BAtt” will flash whenever the battery voltage drops to level “2” 

on the battery display.  To avoid damaging the battery, recharge if it 

becomes empty.
The time clock has a separate back-up battery and is recharged along 

with the main battery. 
The G-Meter is the next option on the SET menu and this shows the 

strength of gravitational or centrifugal force acting on the pilot and 

normally indicates approximately 1G at rest, displayed as G 1_00 
Higher “G” may be encountered during a turn or dive and the G-Meter 

will indicate this to 2 decimal places, for example:  G 2_15   (i.e. just over 

twice the Earth’s gravitational force). 
The maximum G-force  encountered  during  your  flight  can  be  seen 

in the left sub menu. This will be permanently stored and will only be 

updated if higher G-force is registered. This reading can be reset back 

with a long key press. 
This is followed by temperature in degrees Celsius which equates 

to local air temperature if the vario is not heated by sunlight or body 

temperature etc.  A long press gives temperature in Fahrenheit. 
Humidity %  is shown next and can be a useful indication of saturation 

as you approach cloud formations.
