1.2 Purpose of Equipment
The AR6201-(X0X) VHF transceiver enables voice communication in the very
high frequency band between 118.000 MHz and 136.9916 MHz with a
selectable channel spacing of 25 kHz or 8.33 kHz.
The AR6201-(10X) VHF transceiver enables voice communication in the very
high frequency band between 118.000 MHz and 136.9750 MHz with a
selectable channel spacing of 25 kHz only.
1.3 General Notes
The word “frequency”, also used in this document in the sense of
“channel name”, as defined in EUROCAE, ED-23B: chapter 1.3.2.
The word “memory channel” or “channel” used in this document means a
memory place identified by a channel number. On that memory place, a
frequency may be stored for later use.
1.4 Short Description
The AR6201-(X0X) is a single block transceiver ideal to be fitted in all
type of general aviation aircraft and helicopters.
The VHF transceiver is a compact and lightweight single block unit. The
dimensions correspond to the standard instrument diameter of 58 mm (2 ¼
inch). Mounting is by means of four screws (back panel installation).

AR6201-(X0X)
Page 1-2 DV 14300.03/.04 Issue 5 5/2013
All controls and indicators are located on the front panel. The
equipment connectors and the antenna socket are located at the rear of
the unit. On the right-hand side is a Circuit Breaker located.
Frequency Indication
By means of a liquid crystal display (LCD) the frequency indication is
provided. The required operating frequency is set with the rotary knob.
The relation between the real operating frequency and the displayed
frequency is according to standards (ED-23B, chapter 1.3.2). For an
overview, refer to the table below.

Audio Outputs
The transceiver includes two audio outputs: headphone and speaker. The
headphone rated output power is 300 mW into 150 Ohm. The rated output
power from the speaker output is 4 W into 4 Ohm.
Mike Inputs
The VHF transceiver has an input for dynamic microphone (DYN_MIKE) and
an input for standard microphone (STD_MIKE). Each input is able to
operate with single microphone or with 2 microphones of the same type
connected in parallel.
AF Auxiliary Input
The AF auxiliary input enables to connect an external audio source (NAV,
music-player …) to the transceiver. The external audio is audible only
when the transceiver is in Receive Mode.

AR6201-(X0X)
DV 14300.03/.04 Issue 5 5/2013 Page 1-3
Sidetone
The Sidetone is available on the headphone output during transmission.
The Sidetone Volume depends simultaneous on the Intercom Volume setting.
Squelch Operation
A Squelch (muting) circuit suppresses received signals if the signal
quality is poor. There are two kinds of Squelch methods implemented,
Carrier Squelch and Noise Squelch. The carrier squelch rests upon the
signal strength of the received signal; the noise squelch rests upon the
detected noise level and is adjustable in the pilot’s setup menu.
Memory Channels
The VHF transceiver also contains a channel memory function for
automatically/manually channel memory storage of up to 99+9 frequencies.
The last 9 used (active) frequencies are always stored automatically.
The manual storage of up to 99 different frequencies is in addition
possible. It is also possible to assign for each stored frequency a user
defined text label.
Intercom Operation
Aircraft internal communication via connected headsets is provided by
the built in intercom circuit. The Intercom operation may be
automatically via VOX (adjustable) or externally via the intercom switch
triggered. The Setting of VOX-threshold and Intercom Volume is
accessible for the pilot by the Intercom Menu.
Scan Function
In “Scan Function” a dual watch functionality is provided. In case of a
signal is received on both (active/preset) frequencies simultaneously
the signal of the active frequency will become audible with priority at
any time.
Illumination
The illumination of the LCD and the push buttons can be controlled
either directly from the front panel via the pilot’s menu or externally
via the dimming input lines. In case of external dimming is selected the
illumination curve (brightness to voltage relation) can be adjusted in
the Installation Setup.
LOW BATT Indication
The VHF transceiver also contains a monitoring stage for the power
supply voltage. If the supply voltage drops below the adjustable
threshold, the display indicates the message “LOW BATT”.
Emergency Operation
The VHF transceiver is able to operate in emergency operation (9.0 V)
with some reduced performance.
Built In Tests
After power-up, the unit performs a power-up built in test (PBIT).
During PBIT the transceiver displays “WAIT” and the corresponding

AR6201-(X0X)
Page 1-4 DV 14300.03/.04 Issue 5 5/2013
software versions of the control head and chassis module. The continuous
built in test (CBIT) verifies the correct function of the unit
permanently during normal operation. If a problem is detected an error
message will be displayed.
Installation Setup
Configuration of the installation parameters like mike sensitivity, mike
type selection, speaker ON/OFF and further parameters is possible via
the Installation Setup.
Service Mode
The Service Mode is a special configuration mode of the AR6201 via a
RS422 interface with a proprietary serial data communication protocol.

Section 2. INSTALLATION
The installation of the VHF transceiver depends on the type of aircraft
and its equipment. Therefore, only general information is given in this
section.
2.1 Limitations
The installation of the AR6201-(X0X), designed as a single block unit
for use in cockpit environment of general aviation aircrafts including
helicopters, can be performed under consideration of the following
limitations:
•Installations have to be in accordance with appropriate EASA or FAA
approved guidelines.
•The AR6201-(X0X) must be connected to a VHF antenna in order to
satisfy FAA TSO-C169a.
•The conditions and tests for ETSO/TSO approval of this article are
minimum performance standards. Those installing this article, on or
in a specific type or class of an aircraft, must determine that the
aircraft installation conditions are within the ETSO/TSO standards.
Note: Changes or modifications made to this equipment not expressly
approved in written form by Becker Flugfunkwerk may void the
authorization to operate this equipment.
2.2 Unpacking the Equipment and Preparation for Installation
General
Visually inspect the package for signs of transport damage. Carefully
unpack all items and check for completeness.
Additional Required Equipment
The AR6201-(X0X) is intended for use with standard aviation accessories.
The following equipment is required for installation:
•VHF COMM Antenna with coaxial 50 Ωimpedance cable and BNC connector
•Microphone
•Headphone and/or speaker
2.3 Mechanical Installation
The AR6201-(X0X) is designed to be mounted in the aircraft instrument
panel within easy view and reach of pilot/operator. The AR6201-(X0X) is
designed for back-panel mounting by means of four screws, which are
already attached to the AR6201 front. The circular cut out and the
mounting holes have to be prepared in accordance with Figure 2-3. The
location of the AR6201-(X0X) shall be at least 30 cm away from the
aircraft magnetic compass, to avoid any interference to the magnetic
compass by the transceiver. For typical installations, there is no need
for a forced cooling of the AR6201-(X0X). Leave clearance of minimum 5
mm between the AR6201-(X0X) and other avionics to allow air circulation.
Figure 2-1, Figure 2-2 and Figure 2-3 show the unit dimensions.
