RF Exposure Warning
To ensure optimal transceiver performance and to avoid exposure to excessive
electromagnetic elds, the antenna system must be installed according to the
instructions provided.
High voltages exist on the antenna during transmission and tuning. Do not
touch the antenna during these activities. RF burns may result.
Install the grounding system or counterpoise as directed to prevent RF burns
from any metal part of the transceiver.
Safe working distance is based on continuous exposure to CW type transmis-
sions, as set out in the ICNIRP Exposure Guidelines (1998) for occupational expo-
sure. Safe working distance can be reduced with normal voice communication.
For IC and FCC compliance, when the 4050 transceiver is used at a power level
of 150 watts PEP and a 13 dBi gain antenna, the antenna(s) used with this
Transceiver should be located at least 6 metres from the operator and should
not be co-located or operating in conjunction with any other antenna or trans-
mitter.
For IC and FCC compliance, when the 4050 transceiver is used in a vehicular
environment at a power level of 150 watts PEP with 1.5 dBi gain antenna, the
antenna(s) used with this transceiver should be located at least 1.6 metres from
the operator and should not be co-located or operating in conjunction with any
other antenna or transmitter.

The above antennas are identied for reference only. It is important that the
installer and operator maintain a minimum safe separation distance with the
actual antenna used in the installation and to insure, in a vehicular environ-
ment, that the transmitter is only used when persons outside the vehicle are at
least the recommended lateral distance away.
The image below shows an example of minimum recommended separation dis-
tance from antenna in a vehicular environment.

BARRETT 4050 HF SDR TRANSCEIVER - INTRODUCTION
Introduction
The Barrett 4050 Transceiver is an SDR based HF SSB transceiver with a fre-
quency range of 1.6 to 30 MHz in transmit and 250kHz -30MHz. The Barrett
4050 is designed using the latest technology enabling a physically small pack-
age with a full feature complement.
Designed to operate in the most arduous environments, as encountered in off-
road vehicles, vessels and aircraft, the Barrett 4050 will provide many years of
efcient and trouble free service.
The Barrett 4050 supports features such as Selective Call (Selcall), direct dial
telephone connection to base stations tted with telephone interconnect sys-
tems (Telcall), GPS location, 2G and 3G ALE (Automatic Link Establishment), fre-
quency hopping, digital voice, data transmission and remote diagnostics. These
features make the Barrett 4050 HF Transceiver one of the most economical and
versatile HF transceiver available today.
The Barrett 4050 Transceiver caters for increased use of HF data transmission for
Internet email access and point-to-point data applications, by providing a com-
prehensive data modem interface port, high speed transmit-to-receive switch-
ing, a high stability frequency standard and an efcient cooling system option.
The Barrett 4050 Transceiver can be operated in either a local (desktop) con-
guration for base station applications or, with the addition of an inexpensive
mobile pack, in a remote control (trunk mount) conguration for mobile appli-
cations.
The Barrett 4050 Transceiver can be controlled from all major mobile and desk-
top platforms. Full remote control is available via the Barrett 4050 Remote Con-
trol app, providing unprecedented access to all transceiver functionality across
all major platforms.
Operated from 12 V DC to 24 V DC power supplies, the transmitter is rated
at 125-150 watt PEP in voice mode and is protected from over-voltage or
reverse-voltage application.
Up to 1000 channels (depending on the 4050 variant), are available to be eld
or workshop programmable. Auxiliary features such as Selcall, Telcall, scanning,
mute status, alarm system etc. can be individually enabled or disabled for every
channel as required to suit your operation.
Teamed with other matching Barrett products which include antennas, power
supplies, vehicle tracking packages and HF modems, the Barrett 4050 HF Trans-
ceiver becomes a powerful tool, providing solutions to many long distance
communication requirements.

Ensure the transceiver is attached to a power source appropriate for your situa-
tion. Please refer to the Basic Operation section on page 13.
Momentarily press the on button,
, to turn the transceiver on.
Pressing the same button for three
seconds powers down the trans-
ceiver.
Alternately, pressing the same but-
ton briey brings up the Power
Button Menu allowing the trans-
ceiver to be rebooted or shut
down.
