LX8000 (LX8080) Version 2.6 September 2011

5.1 Setup Mode

In the setup menu users can configure the LX8000. Turn the bottom-right knob or press the
UP/DOWN arrow on the remote stick to select the appropriate setup item. Press the
SELECT button or CHECK button on the remote stick to enter a menu. A dialogue or sub-
menu will open.
The setup menu is slightly different on the rear seat device as not all options are applicable.
Items which are marked with an asterisk (*) are available only in the front seat setup menu.

5.1.1 QNH and RES

Turn the bottom-right knob to select the required entry field. Press the EDIT button and
start editing the value.

5.1.1.1 QNH*

Using this feature it is possible to offset the altitude datum which could have changed due to
pressure changes during the flight. Since changing the QNH influences the indicated
altitude, care should be taken when changing the value as an incorrect setting can upset the
final glide calculation.

5.1.1.2 Safety Altitude

This setting is the altitude reserve or safety altitude and is the height that the instrument
adds to the final glide altitude required so that the glider arrives over the final glide
destination at the selected safety altitude. Once the safety altitude has been specified, the
pilot has to keep the final glide indicator on 0 to arrive at the safety altitude.

5.1.1.3 Magnetic Variation

The LX8000 has a built-in Earth magnetic field model. If Auto variation is checked the
magnetic variation is derived from this model, otherwise the user can enter a custom value.

5.1.1.4 ETA/ETE Calculation

In changing this value you may choose from four different methods to calculate the
estimated time of arrival to the navigational point. Calculation is always divided into straight
flight and climb time calculations.
