Introduction
The L-Band IF Transceiver 6700/6900 series is manufactured
in a number of variants. CE-compliant versions are marked
with the , or symbols.
This section describes how to ensure the L-Band IF
Transceiver 6700/6900 series complies with the European
Electromagnetic Compatibility Directive 89/336/EEC and the
European Low Voltage Directive 73/23/EEC as called up in
the European Radio and Telecommunications Terminal
Equipment Directive 1999/5/EC.
The CE Declarations of Conformity for the range of products
are listed on page 108, Associated documents. These
documents can be made available on request to Codan or a
Codan-authorised supplier.

L-Band IF Transceiver 6700/6900 series User Guide 5
European Radio and Telecommunications
Terminal Equipment Directive
CE-compliant versions of the L-Band IF Transceiver
6700/6900 series have been tested and comply with the
following standards (articles of the R&TTE Directive):
• Article 3.1a: EN 60950
• Article 3.1b: ETSI EN 301 489-1
• Article 3.1b: ETSI EN 301 489-12
• Article 3.2: ETSI EN 301 428
• Article 3.2: ETSI EN 301 443
Compliance with these standards is sufficient to fulfil the
requirements of the Radio and Telecommunications Terminal
Equipment Directive 1999/5/EC, which encompasses the
following directives:
• European EMC Directive, 89/336/EEC
• European Low Voltage Directive, 73/23/EEC with no
lower voltage limit
Product marking and labelling
Any equipment supplied by Codan that satisfies these
requirements is identified by the , or
markings on the model label of the product.
CAUTION
Some countries may restrict the use of satellite
communications equipment on certain
frequency bands or require such equipment to
be licensed. It is the user’s responsibility to
check the specific requirements with the
appropriate communications authorities.

Declaration of Conformity
The CE Declarations of Conformity and Expert Letters of
Opinion for each specific product are listed on page 108,
Associated documents. These documents can be made
available upon request to Codan or a Codan-authorised
supplier.
Protection of the radio spectrum
It is the responsibility of the user to ensure any modem used in
conjunction with the L-Band IF Transceiver 6700/6900 series
complies with EN 301 428 or EN 301 443 so that CE
compliance with respect to radiated spurious signals is
maintained. If necessary, contact Codan for more information.
To set up the BUC for CE-compliant operation you must:
1Enter the STD0 command.
This sets the default transmit state on powerup to Off.
1Enter the STO1 command to activate the transceiver.
Health requirements (human exposure to
electromagnetic fields)
The L-Band IF Transceiver 6700/6900 series has been
assessed against the health requirements in article 3.1a of the
R&TTE Directive (1999/5/EC) complying with VDE0848,
ICNIRP and FCC health requirements.

Electromagnetic compatibility and safety
notices
Radiation safety
Electromagnetic compatibility
To ensure compliance with the EMC Directive is maintained,
you must:
1Use standard shielded cables supplied from Codan
(where applicable).
1Ensure the covers for the equipment are fitted correctly.
WARNING
A radiation hazard exists if the BUC is operated
with its RF output unterminated. Do not operate
the BUC without a load or termination attached
to the RF output.
CAUTION
If it is necessary to remove the covers at any
stage, they must be refitted correctly before
using the equipment.

Electrical safety
To ensure compliance with the European Low Voltage
Directive is maintained, you must install the L-Band IF
Transceiver 6700/6900 series in accordance with the
following safety precautions. These precautions must be
checked before applying power to the transceiver.
WARNING
For LBUCs, a protective earth connection must
be connected to the protective earth terminal on
the LBUC (see page 9, Earth symbols).
WARNING
For MBUCs:
• A protective earth connection must be
included in the mains wiring to the MBUC
(see page 9, Earth symbols).
• As the MBUC is intended for permanent
connection to the mains supply, a readily
accessible switch or circuit breaker must be
incorporated in the mains wiring to enable
easy isolation of the unit.
• The isolating switch must disconnect both
poles simultaneously. However, if you can
positively identify the neutral conductor, you
may have a single-pole isolating device in the
live conductor.
