INTRODUCTION ( Open System Digifly )
The Digifly viewing units were designed also to co-operate with each
other in the same system. This is known as “multiscreen” system
and it is made up of different Display Units (DU7-DU8) linked to the
flight recorder. Among all the connected units, only one must be set
up in MASTER mode, whereas all the others must be set up in SLA-
VE mode. In this manner, the viewing device (MASTER) will direct
data transmission operations and one or more devices (SLAVE) will
operate only as viewers. Only the MASTER device will be capable
of adjusting the flight-recorder settings. The MASTER/SLAVE mode
can be set in Set Up.
Therefore the Digifly Open System is now even more advanced and
complete in order to meet any need of pilots and flight enthusiasts,
significantly increasing the precision and safety standards supplied
by the instruments presently available in the market.

The following figure show the keyboard's main functions.
2.3.1 - Turning on / off.
Before turning on the instrument make sure that all connections were
made correctly. Make sure the engine is turned on before the instrument.
To turn on the DUx, press the POWER button. After a few seconds, the
Moving Map or Instrumentation page is viewed to search for the
connection and for the initial internal tests.
To turn off the DUx, press (and keep pressed for at least 2 seconds) the
POWER button again.
2.3.2 - Contrast.
To regulate contrast keep the button CONTR pressed until the contrast
menu appears. Now the regulation is executed with the UP-DOWN
ARROW buttons. Press CONTR again to quit the menu.
N.B. In the System Test page, contrast is regulated just pressing the
CONTR button.

3.5.2 - Measure units.
There are four presettable measure units:
Temperature (temp. unit) : °C or °F
Altitude (unit 1) : mt. or ft.
Speed (unit 2) : Km/h or MPH or Knots
Pressure (unit 3) : mb or iHg
3.5.3 - Warnings.
For each in line it is possible to fix minimum and maximum limits not
to be exceeded.
It is possible to preset 11 engine limits (in lines from 1 to 11), and 1 flight
limit(speed)can bepreset(minimum speed willbestall speed,maximum
speed will be VNE).
Limits on bar indicators are represented by little arrows on their side,
limits on round instruments are represented by a tally on the scale.
When a preset limit is exceeded the relative warning appears in the
specific window.
At the same time the bar indicator starts blinking.

3.1.1 - Altimeters.
This function allows the commutation of the displayed altimeter (QNE or
QNH or QFE): it is activated by pressing ZOOM IN.
When you enter this mode the window (2) of the altimeter is high lighted;
with UP ARROW and DOWN ARROW keys it is possible to change the
reference pressure (by pressing for a very short time the variation,
indicated by a beep, is a 1/10 of Millibar or relative inches of Hg).
If QFE is evidenced you zero the altitude by pressing CLEAR.
By pressing LEFT ARROW and RIGHT ARROW you change the
indication of altitude.
Press ZOOM IN or ZOOM OUT to exit.
3.1.2 - Recorder.
It records flight data between two time intervals.To activate the recording
press UP ARROW and a blinking “R” will appear (12) on the upper left-
hand corner of the screen.
If you push ENTER within 5 seconds, the recording is activated, if not,
the recorder will not start working.
Tostop therecording pressDOWN ARROWandENTER within5seconds.
The recording is automatically interrupted when the maximum recording
time is exceeded.
The maximum recording time is related to the Sampling rate, that is the
frequency of recording of the instrument ( from 1 to 50 secs ).
This frequency is presettable in the Set Up.
When you activate the recorder the previous recorded flight will be
completely deleted.
3.1.3 - Switching the central window.
By pressing the ZOOM OUT key the central window switches from GPS
data to secondary instruments and viceversa.
3.2 - Functions menu.
Press MENU to enter it. Press key DOWN ARROW or UP ARROW to
