Safety precautions
Placement
Set the system up on an even surface away from direct sunlight,
high temperatures, high humidity, and excessive vibration. These
conditions can damage the cabinet and other components, thereby
shortening the unit’s service life.
Place it at least 15 cm away from wall surfaces to avoid distortion
and unwanted acoustical effects.
Do not place heavy items on the unit.
Voltage
Do not use high voltage power sources. This can overload the unit
and cause a fire.
Do not use a DC power source. Check the source carefully when
setting the unit up on a ship or other place where DC is used.
AC mains lead protection
Ensure the AC mains lead is connected correctly and not damaged.
Poor connection and lead damage can cause fire or electric shock.
Do not pull, bend, or place heavy items on the lead.
Grasp the plug firmly when unplugging the lead. Pulling the AC
mains lead can cause electric shock.
Do not handle the plug with wet hands. This can cause electric
shock.
Foreign matter
Do not let metal objects fall inside the unit. This can cause electric
shock or malfunction.
Do not let liquids get into the unit. This can cause electric shock or
malfunction. If this occurs, immediately disconnect the unit from the
power supply and contact your dealer.
Do not spray insecticides onto or into the unit. They contain
flammable gases which can ignite if sprayed into the unit.
Service
Do not attempt to repair this unit by yourself. If sound is interrupted,
indicators fail to light, smoke appears, or any other problem that is not
covered in these instructions occurs, disconnect the AC mains lead
and contact your dealer or an authorized service center. Electric shock
or damage to the unit can occur if the unit is repaired, disassembled
or reconstructed by unqualified persons.
Extend operating life by disconnecting the unit from the power source
if it is not to be used for a long time.

Basic connections (for supplied accessories)
•
Plug the AC mains lead into a household mains socket only after
all other connections have been made.
•
To prepare the AM loop antenna wires and speaker cords, twist
the vinyl cover tip and pull off.
Connect the FM indoor antenna.
Tape the antenna to a wall or column, in a position where radio
signals are received with the least amount of interference.
Note
For best reception sound quality:

•
To prevent damage to circuitry, never short-circuit positive (+)
and negative (–) speaker wires.
Caution
• Use the speakers only with the recommended
system.
Failure to do so may lead to damage to the
amplifier and/or the speakers, and may result in
the risk of fire.
Consult a qualified service person if damage has
occurred or if you experience a sudden change
in performance.
• Do not attach these speakers to walls or ceilings.
Connect the AC mains lead.
