2 INSTALLATION
2.1 Unpacking
•Carefully unpack the equipment.
•Damages due to transport must be reported to the shipping
company.
•Save the shipping container and all packing materials to
substantiate your claim.
For storage or reshipment the original packaging should be
used.
2.2 Requirements
•In arrangement with an avionics shop, location and kind of the
installation are specified. An avionics shop can install all cables.
Refer to 1.9 Accessories for cable looms.
•The equipment is front-laterally fixed in the instrument panel in a
57 mm cut-out using four M4 screws (included in delivery).
•Leave sufficient space for the installation of cables and connectors.
•Avoid sharp bends and the routing of cables close to control
cables.
•Avoid installation close to heat sources.
•Care for adequate convection cooling.
Note 2.4.2 Microphone Connection BEFORE mounting!

2.3 Antenna
Use an omni-directional vertical polarized VHF COM antenna with a
50 Ohm impedance. Wideband comm antennas provide efficient
operation over the VHF communications band.
Installation recommendations:
•consider the manufacturer’s recommendations
•Mount the antenna in vertical position so on or under the belly that
it is as far distant as possible from all protruding parts (propeller,
chassis, vertical stabilizer).
•To avoid any mutual interference of the radios, the antenna
isolation between a voice transmission and a navigation antenna
as well as between double COM antennas should be as high as
possible. A separation of 2 meters usually is sufficient.
•The metallic contact between airplane surface and antenna must
be very good. On non-metallic airplanes a metal foil (min. 80 cm x
80 cm) shall be used as electrical counterweight on the inside of
the belly.
•For glider installation the internal antenna installed by the
manufacturer should be used.
2.4 On-Board Wiring
2.4.1 Annotations
•Keep wiring as short as possible.
•Avoid cable running near strong high frequency sources such as
ignition coil, generator or battery charger.
•Refer to 1.9 Accessories for cable looms.
•All cables can be installed by an aeronautical-engineering
enterprise.
•The cables must be approved for airplane installation.
•conductor cross-section:
opower, GND: AWG18 (0.96 mm²)
osignals: AWG22 (0.38 mm²)
•external slow-blow fuse (4 A) required.

2.4.2 Microphone Connection
Microphone inputs:
MIC 1: switchable („Mic Switch“on the right side of the equipment) for
•dynamic microphones (factory setting)
•standard microphones
MIC 2: only for standard microphones
The input for standard microphones is appropriate for input voltages of
50 mVpp to 2 Vpp. This input has a bias voltage of 8 V at 330 ohms.
Sensitivity is adjustable in the init menu with MIC.
The input for dynamic microphones is appropriate for input voltages of
5 mVpp to 10 mVpp. This input has no bias.
Use microphones of the same type, since the settings described in the
following are always concerning both microphone inputs.
Check setting of the MIC switch on the right side of the
radio BEFORE mounting!
(Factory setting: dynamic microphone)
Two microphones may be connected parallel per
microphone input.
2.4.3 Headphone Connection
Headphones may be connected parallel as long as the total impedance
doesn’t fall below 8 Ω.

2.4.4 Display Illumination
From No 2 of 1.3 Survey of Part Numbers!
„DISPLAY_LIGHTING“ (Pin 4) must be connected according to the
desired function:
•GND illumination off
•+UB illumination on
•dimmer illumination external adjustable
•switch illumination external switchable
If pin 4 is connected to an external voltage supply, illumination can be
adjusted by the DIM function (refer to 4.4.5, page 23).

2.5 Microphone Settings
Settings of MIC- und VOX-values are essential for intercom operation.
Using VOX the threshold level is adjusted so that usual flight noise is not
transmitted to the headphones, but only an additional signal caused by
speaking will start intercom operation.
With very strong background noise or uncompensated microphones VOX
can be deactivated by setting VOX01.
In this case intercom is activated using a press-to-talk key (PTT), which
connects pin 12 (intercom) of the equipment connector to GND. If
required, e. g. in a tandem cockpit, use two parallel connected PTT keys.
For operating in VOX mode pin 12 has to be connected permanently to
GND.
Transmission merely operates when PTT is pressed.
The suppression of background noise is only possible using differential
microphones, as they are usual with modern headsets. Normal electret
microphones are not suitable.
For setting refer to 4.2.1 MIC-setting.

2.6 Installation Check
When installation is completed all steering and control functions of the
aircraft are to be examined, in order to exclude disturbances by the
wiring.
Subsequently, check antenna matching. Insert a standing wave meter,
respectively a direction-sensitive RF power meter into the antenna line.
Determine standing wave ratio (SWR) over the entire operating
frequency range. The SWR shall not exceed 3:1 (the reflected power
shall not exceed 25% of the forward power). If this value is exceeded, a
mismatching is present, which can be caused e. g. by incorrect or
insufficient electrical counterweight, bad contacting or incorrect radiator
length.
With COM antennas attached on the fuselage lower side
this measurement must be accomplished during flight, in
order to avoid faulty measurements.
After the antenna measurement a communication test with an
aeronautical station shall be accomplished.
Furthermore a test flight is recommended, in order to guarantee the
proper in-flight operation of the radio:
•In a flight altitude of at least 1500 ft contact a ground station in a
distance of at least 100 km (60 nautical miles).
•Pay attention to unusual electrical interference.
•If possible, perform the radio test on frequencies within the upper
and lower VHF communication frequency range.
