3 How to use the unit
The unit comes with an external rotary switch with push button, and you can access all
the options with that button by either pressing it or turning it left/right.
3.1 Setup
The unit is ready for operation immediately after power on and vario needle is back to
zero. The following settings can be set up on the ground, and also during flight.
• UNITS (selection of m/s or kts)
• RNG for selection of vario needle range ( 2.5, 5 and 10 m/s or 5, 10 and 20
knots)
• FIL for selection of vario signal filter in steps from 0.2 to 5 (damping of response
time)
To enter into Setup menu press the button on the external rotary switch once, and UNIT
item will appear. Press the button again to select RNG, once more for FIL, and another
press will take you back out of the setup. To change value of the selected option, rotate
the switch to the left or to the right. The Setup menu will also close automatically after a
couple of seconds without any new command. All settings will remain after power off.
