The Trantec SD-7802 Receiver represents our commitment to our customers by
providing high quality, reliable wireless audio links, using our considerable design
expertise gained over many years as a leading edge manufacturer.

Thank you for purchasing this product and please study this manual, especially the safety
instructions before installing and using this equipment.

1. SAFETY PRECAUTIONS

• Keep the system away from direct sources of heat, e.g. Central heating radiators,
heaters, and direct sunlight.

• Do not expose the unit to an environment where it could be splashed with liquids as this
may result in fire or electric shocks.

• Keep the system clean by using a slightly damp cloth. Never use household cleaning
agents or solvents.

• Avoid using or storing the system in damp or dusty conditions.

• Always disconnect from the AC outlet when not in use.

• The unit is designed for indoor use, do not install it outdoors. If the unit should get wet,

there is a danger of electric shock.

• Never remove the external covers of the unit, exposing the electronics, or modify the unit
in any way.

• Do not handle the mains lead with wet hands.

• Never pull the cord of the AC lead when disconnecting from an AC outlet. Always hold

the plug.

• Ensure that the mains plug is securely inserted in the wall outlet.

• Route the AC power lead in such a way that it is not likely to be stepped on or tripped

over.

• Do not use if the AC lead becomes damaged. This may result in fire or electric shock.

• Never touch any part of the equipment during a thunderstorm as this may result in severe

electric shock.

• Use the unit only with the voltage specified on it. Using a voltage higher than that
specified may result in fire or electric shock.

• Do not cut, kink, otherwise damage or modify the power supply cord. In addition, never
place heavy objects (including the unit itself) on the power cord. Doing so may result in
fire or electric shock.

• Always mount the unit on a stable surface or install in a stable location. The unit may
otherwise fall causing personal injury and/or property damage.

• When moving the unit, be sure to remove its power supply cord from the wall outlet first.
Moving the unit with the power cord connected to the outlet may cause damage to the
power cord, resulting in fire or electric shock.

• Do not place heavy objects on the unit as this may cause the unit to fall resulting in
personal injury and/or property damage. In addition, the object itself may fall off and
cause injury and/or damage.

• Do not place containers of liquid or metallic objects on top of the unit. If they accidentally
spill into the unit, this may cause a fire or electric shock.

Should the covers be removed or there is any other breach of the above instructions, the
warranty becomes null and void, in addition to personal risk from burns and/or electric
shock.

If any of the following conditions occur when using the unit, switch off and remove the AC
lead from the outlet immediately and contact your nearest dealer.

• Smoke or unusual smell

• Water or foreign object inside the unit

• Physically damaged housings
