Button 2: Digital Exhaust Gas / Cylinder Head Temperature Mode
Using this button, the numerical indication for exhaust gas and cylinder head temperature
underneath the graphical representation of these figures is set. Following each sequential
operation of the button the exhaust gas and cylinder head temperatures of an individual
cylinder are displayed. In this, the display jumps automatically from the number of the
current cylinder to its current temperature. After the fourth cylinder the display switches
to the Automatic mode, which gives both the number of the cylinder with the highest
exhaust gas temperature as well as (beside it) the number of the hottest cylinder.
Alternating with this, the associated temperatures are displayed.
Button 3: Switch in Autotrack
In the Autotrack mode changes in the engine values are shown. If button 3 is operated
in flight, variations from the current values will be displayed, in that the relevant circular
instrument and the annotation AUTOTRACK will start to flash.
In order to leave the mode, button 3 must be operated. The mode is left automatically
if there is a critical value to be indicated.
Button 4 - Fuel Computer Mode
By operating button 4 the display is switched from fuel flow (FUEL FLW) to a numerical
indication underneath it. There are 4 modes, which are called up by pressing button 4

is only available if the ADD mode - add up fuel - has previously been activated.
