1 Introduction
The LX 16-D built in sensor is high quality pressure transducer, to guaranty high
accuracy of vario signal and its zero . A modern low-power microcontroller drives the
LCD vario indicator and supports input controls. All necessary inputs are made by using
of one external rotary switch with a push button.
The unit has no on/off switch, therefore we recommend that you install an external
switch, or just use an avionic master switch. A 1 amp fuse is recomended.

3 How to use the unit
with push button
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.
