Preface

Dear Customer,

Thank you for purchasing BECKER products.
We are pleased that you have chosen our product and we are confident

that it will meet your expectations.
AR620X-(XXX) VHF Transceivers are a modern family of communication

equipment that have comprehensive capabilities and significantly extend
the typical aeronautical transceivers.

Despite its small size and weight 620X- aircraft radio include inter
alia:

• Sensitive receiver which meets the most recent requirements of ED­23C, including the ability to work in the offset-carrier (climax)
operation in 25 kHz and 8.33 kHz channel spacing (class H2).

• Receiver that includes SCAN (dual watch) mode. This allows
simultaneous monitoring of two different VHF frequency channels
without interrupting communication on the active frequency.

• High efficiency transmitter which delivers more than 10W modulated or
un-modulated output power at 28V supply voltage or 6W at 12V. Low
power consumption allows longer operation from battery.

• Extended built-in intercom which can work as:

o 4-way intercom with isolation mode – passengers could continue

conversation or listening to music from MP3 player at the same
time as pilots talk via intercom or communicate with the tower.

o 2-way intercom for tandem operation – pilot and co-pilot work

with separate controllers and can control their individual
audio parameters, like volume or VOX. This mode is preferred
especially for training due to full synchronization of LCD
contents.

• Non-volatile memory for storing:

o 99 VHF channels can manually be labeled for storage of VHF

channels

o 9 recently selected VHF channels are automatically stored

Audio Outputs

The 620X VHF Transceiver includes four fully configurable outputs:

• Headphone 1 output, rated output power is 300 mW into 75 Ohm.

• Headphone 2 output, rated output power is 200 mW into 75 Ohm.

• Speaker output, rated output power is 4 W into 4 Ohm.

• LINE-OUT output intended for ground station use only

Note: Headphone 2 and speaker output cannot be active at the same time

Mike Inputs

The VHF transceiver has an input for dynamic microphone (DYN_MIKE) and
an input for standard microphone (STD_MIKE).

The 620X VHF Transceiver provides four microphone inputs:

• standard microphone input 1 (STD_MIKE1)

• standard microphone input 2 (STD_MIKE2)

• standard microphone input 3 (STD_MIKE3)

• dynamic microphone input (DYN_MIKE)

Each input is able to operate with one single microphone or with two
microphones of the same type connected in parallel.

AF Auxiliary Input

The AF auxiliary provides the interface to connect an external audio
source (e.g. NAV, music-player) to the transceiver. Interconnection of
multiple external audio sources on this particular port requires

DV 14307.03 Issue 1 09/2013 Page 1-7

AR6201 - RT6201 - RCU6201 - AR6203

additional external decupling/isolation resistors. The external audio is
audible only when the transceiver is in receive mode.

The individual audio volume is set directly at the particular external
equipment.

Sidetone

The sidetone is available on the headphone output during transmission.
The sidetone volume automatically adapts to the intercom volume setting.

Squelch Operation

When enabled the squelch (muting) circuit suppresses weak si gnals. There
are two kinds of squelch methods implem ented: carrier squelch and noise
squelch. The carrier squelch depends on received signal strength and is
adjustable in the installation setup; the noise squelch depends on
detected noise level and is adjustable in the pilot setup.

Memory Channels

The memory function allows storage of up to 99+9 frequencies. This
memory may contain up to 99 frequencies stored manually or programmed
from PC that can be labeled with VHF channel numbers or assigned text
label. Additionally the last recently used (active) 9 frequencies are
stored automatically as “LAST” channels. A user defined text label can
also be assigned for each stored frequency.

Intercom Operation

Aircraft internal communication via connected headsets is provided by
the built-in intercom circuit. The 620X has two intercom circuits:
“Front row” and “Back row”. A maximum of four headsets can be connected
(for example pilot & copilot on first circuit and two passengers on
second circuit).

Scan Mode

In scan mode a dual watch function is provided. T he device is capable of
monitoring frequencies on two channels, active & preset simultaneously.
The signal of the active frequenc y will always b e audible, since it will
have priority at all times.

Tandem operation

Tandem mode enables operation of two controllers simultaneously. The
controllers are synchronized, so that both display the same information

Illumination

The illumination of LCD and push buttons can be controlled either
directly from the front panel via the pilots menu or externally via the
dimming input lines. If the external dimming is selected, the

Page 1-8 DV 14307.03 Issue 1 09/2013

AR6201 - RT6201 - RCU6201 - AR6203

illumination curve (brightness to voltage relation) can be adjusted in
the installation setup.

LOW BATT Indication

The VHF transceiver monitors power suppl y voltage. If the supply voltag e
drops below the adjustable threshold, the display indicates the message
“LOW BATT”. If the power supply voltage drops further, emergency
operation mode is entered.

Emergency Operation

If the power supply voltage drops below 10.25 V, the VHF transceiver
continues operation with degraded perf ormance. In case the power supply
drops below 9.0V the unit is automatically switched off.

Built-in Tests PBIT and CBIT

After power-up, the unit performs a se lf-test (power-up built-in test /
PBIT). During PBIT the transceiver displays “WAIT” and the correspo nding
software versions of both the control head and chassis module.

If faults are detected during PBIT, the error message “FAILURE press an y
key” is displayed. If no faults are detected the transceiver
automatically activates the mode set before last power-off.

During normal operation a continuous built-in test (CBIT) permanently
verifies the correct operation of the unit. If a problem is detected
during CBIT, an error message will be displayed.

Installation Setup

Configuration of the installation parameters such as mike sensitivity,
mike type selection, speaker enable/disable plus other parameters are
available via the installation setup.

Service Mode

The service mode is a special configuration mode accessible via RS422
interface with a proprietary serial data communication protocol. This
mode is for use by authorized maintena nce organizations during aircraft
service on ground only.
