1.2 Purpose of equipment
The VHF transceiver enables voice communication on 760 channels in the 118.000 MHz to
136.975 MHz range with a channel spacing of 25 kHz. It complies with the requirements of ICAO An-
nex 10 valid from 01.01.1995.
1.3 General description
The VHF transceiver is designed with sufficient mechanical strength to enable it to be fitted in an air-
craftwithoutanylimitations.Thereisnorestrictionwithintheverifiedenvironmentalclassesonfittingin
theinstrumentpanelorcentreconsoleoroperatingconsole,orfixedmountinginthefuselage,ofallty-
pes of aircraft including helicopter.
The VHF transceiver has been developed as a single block unit. Its dimensions correspond to the
ARINC standard for control equipment. It is held in place by means of four DZUS fasteners. All con-
trols, indicators and displays are located on the front plate. The back side of the unit contains: the two
unit connector plugs for connection to the aircraft wiring system, and the antenna.

Afteritisswitchedon,theunitperformsaselftest.Allsegmentsofthedisplaysflashduringtheselftest.
If faults are detected, the LCD’s (liquid crystal display) displays a fault code for approximately five se-
conds. The VHF transceiver then automatically activates the mode set before it was switched off.
The VHF transceiver is fitted with a single superheterodyne receiver. A squelch (muting) circuit sup-
pressestransmittersordisturbancesbelowacertainfieldstrength.Theswitchingthresh oldcanbeset.
The squelch function can also be switched off.
Thetransmitteris designed to bewidebandover the 118.000 MHz to136.975MHz range. The sideto-
ne is automatically switched to the headphone output during transmission.
Theoscillatorfrequencyofthereceiverand thetransmittingfrequencyofthetransmitteraregenerated
byaVCO(voltagecontrolledoscillator).Thisismonitoredbyadigitalfrequencyevaluationcircuit.This
digital frequency processing operates in conjunction with a microprocessor.
The microphone inputsare designed for parallel both dynamic and standard microphones. The inputs
are connected to a dynamic volume compressor which keeps the modulation voltage constant over a
wide input voltage range.
The frequency indication is by means of two liquid crystal displays (LCD). The required operating fre-
quencyissetusingtheMHzandkHzfrequencyselectorswitches.TheMHzrotaryswitcheng agesat1
MHz steps and the kHz rotary switch at 25 kHz steps.
The VHF transceiver also contains a memory device for storing 20 different frequencies which remain
stored even with the unit switched off without an auxiliary battery.
Aircraft internal communication is possible in the IC (intercom) mode. Activation is by means of an ex-
ternal IC button (or switch) which is to be connected to the equipment connector.

nals can, however, only be monitored in the reception mode.
Ifilluminationof the LCD’s isrequired,this can be connectedeitherdirectly to the supplyvoltage or via
a dimmer.
Special functions
VHF transceiver contains some special functions which can be set in the service mode.
pThesquelch sensitivity, IC, sidetoneandAFexternalinput volume can bedirectlyset
on the control unit.
pThe frequency setting can be inhibited. The VHF transceiver then operates only on
the frequencies stored in the storage channels.
pThe storage of frequencies in the storage channels can be inhibited.
pStored frequencies can be erased.
pAccess to the service mode can be interlocked with a 4-digit password.

Section II INSTALLATION
2.1 General
The installation of the VHF transceiver depends on the type of aircraft and its equipment. Therefore,
only general information can be given in this Section.
2.2 Testing before installation
2.2.1 General
Before installing the VHF transceiver in an aircraft, inspect the unit for signs of transp ort damage.
2.2.2 Visual Inspection
Before commissioning, visually inspect the unit paying particular attention to the following defects :
(a)Dirt,dents,scratches,corrosionorbrokenattachingparts,damagedpaintworkonhousing,partsof
the housing and panel.
(b)Dirt or scratches on the identification plate, front panel, LCD or inscriptions.
(c) Dirt, bent or broken pins, displaced inserts of plugs and sockets.
(d)Dirt and mechanical damage to pushswitches and operating knobs.
2.3 Mechanical installation
2.3.1 Mechanical installation of VHF transceiver.
The VHF transceiver is designed for instrument panel or control console mounting in the aircraft.
The equipment is secured to the airframe by four DZUS fasteners. Mounting information for the faste-
nerstripsiscompiledinFig.2-9,Fig.2-8showsalldimensionsrelevanttoinstallingthe transceiver.
Inaircraftwherenopanelcutoutisprovided,itcanbeproducedinaccordancewiththedimensionalre-
quirements as per Fig. 2-9, it being good practice to use the flat fastener strips.

2.4 Installation wiring
2.4.1 General
The installation wiring is shown in Fig. 2-10 and Fig. 2-11.
(a)Useonlycablewhichisfitforuseinaircraft(selfextinguishing).AWG20forpowersuppl yandAWG
22 for other cables.
(b)Fit rubber sleeves over the solder joints on the equipment connector.
(c) Protect the power supply with a 7,5 A fuse or circuit breaker.
NOTE
The VHF transceiver is protected internally by a 5 A fuse.
(d)NoRFcablesshouldbeincludedinthecableharnessesofthesystemandtheroutingofconnecting
cables alongside cables which carry audio power or pulses should also be avoided.
(e)Carefully check the wiring before switching on the unit and check particularly that (+) and (-) have
not been reversed.

2.4.2 Microphone connection
The VHF transceiver enables a maximum of two dynamic microphones and two standard micropho-
nes(d.c.supply)tobeconnectedatthesametime.Abalancedinputtransformerwithanimpedanceof
200 Ohm is fitted at the input of the dynamic microphone.
NOTE
The dynamic mike input sensitivity can be changed in the service mode.
2.4.3 Speaker connection
A 4Ohm to 8 Ohm speaker can be connected to audio output P2- 1AF-asym.
CAUTION
The magnetic field of a speaker influences the magnetic compass. When choosing the
mounting point, a minimum distance of 1.3 m must be maintained between the speaker
and the magnetic compass.
2.4.4 Headphone connection
Up to two headphones with an impedance of 600 Ohm can be connected to the audio output P2- 2,3
AF-HI/LO.
2.4.5 Intercom mode “IC connection”.
The intercommode is designedfor aircraft with a highnoise level andassumes operation usinghead-
sets. Additional wiring on the equipment connector with an IC switch is necessary (refer to Fig. 2-10
and Fig. 2-11).
ThenormalR/TcommunicationtakesplacewiththeICswitchin the OFF position. When theICswitch
is set to ON, R/T communication can be carried on as before but intercommunication is also possible
between two crew members. The IC is switched off during transmission. The IC volume can be chan-
ged in the service mode.
2.4.6 Auxiliary" audio input
The AF-AUX (P2/4) auxiliary audio input enables the switching of audio signals from other equipment
in the aircraft. The switched-in audio signals can, however, only be monitored in the rec eption mode.
The facility to switch two units together will be used particularly in those aircraft which are fitted with a
VHFtransceiverandanNAVreceiver.Anaudioinputvoltageof1Vto8V,600Ohmisnecessarytodri-
