Getting Started
Putting Batteries in the Remote Control
Before using the remote control, put two supplied batteries first.
• When using the remote control, aim the remote control directly at
the remote sensor on the center unit.
1. On the back of the remote control, remove the
battery cover.
2. Insert batteries. Make sure to match the polarity:
(+) to (+) and (–) to (–).
3. Replace the cover.
If the range or effectiveness of the remote control decreases, replace
the batteries. Use two R6P(SUM-3)/AA(15F) type dry-cell batteries.
CAUTION:
Follow these precautions to avoid leaking or cracking cells:
•Place batteries in the remote control so they match the polarity: (+)
to (+) and (–) to (–).
•Use the correct type of batteries. Batteries that look similar may
differ in voltage.
•Always replace both batteries at the same time.
•Do not expose batteries to heat or flame.
Before Installation
General Precautions
• DO NOT insert any metal object into the center unit.
• DO NOT disassemble the center unit or remove screws, covers, or
cabinet.
• DO NOT expose the center unit to rain or moisture.
Locations
• Install the center unit in a location that is level and protected from
moisture.
• The temperature around the center unit must be between 5˚C and
35˚C.
• Make sure there is good ventilation around the center unit. Poor
ventilation could cause overheating and damage the center unit.
Handling the center unit
• DO NOT touch the power cord with wet hands.
• DO NOT pull on the power cord to unplug the cord. When
unplugging the cord, always grasp the plug so as not to damage
the cord.
• Keep the power cord away from the connecting cords and the
antenna. The power cord may cause noise or screen interference. It
is recommended to use a coaxial cable for antenna connection,
since it is well-shielded against interference.
• When a power failure occurs, or when you unplug the power cord,
the preset settings such as preset FM/AM channels and sound
adjustments may be erased in a few days.
Checking the Supplied Accessories
Check to be sure you have all of the following supplied accessories.
The number in the parentheses indicates the quantity of the pieces
supplied.
• Remote Control (1)
• Batteries (2)
• AM Loop Antenna (1)
• FM Antenna (1)
• Video Cord (1)
• AC Plug Adapter (1) (not supplied for Hong Kong)
• Speaker Cords
6 m (4): For subwoofer
For the satellite speakers on the following positions:
left front, right front, and center
10 m (2): For the satellite speakers on left and right rear positions
If anything is missing, contact your dealer immediately.
Adjusting the Voltage Selector
Before connections, always do the following first if necessary.
Set the correct voltage for your area with the voltage selector switch
on the rear panel. Slide the voltage selector using a screw driver, to
select the voltage where you are plugging in the system.

Connecting the FM and AM Antennas
FM antenna (supplied)
If FM reception is poor, connect
outdoor FM antenna (not supplied).
AM antenna connection
Connect the supplied AM Loop antenna to the AM and Hterminals.
Turn the loop until you have the best reception.
• If reception is poor, connect an outdoor single vinyl-covered wire
to the AM terminal. (Keep the AM Loop antenna connected.)
Notes:
If the AM Loop antenna wire is covered with vinyl, remove
the vinyl by twisting it as shown in the diagram.
Snap the tabs on the loop into
the slots of the base to
assemble the AM Loop
antenna.
If AM reception is poor, connect single vinyl-covered
wire (not supplied).
AM Loop antenna
(supplied)
FM antenna connection
Connect the supplied FM antenna to the COAXIAL FM 75 Ω
terminal as temporary measure.
Extend the supplied FM antenna horizontally.
• If reception is poor, connect an outdoor antenna. Before attaching
a 75 Ωcoaxial cable (with a standard type connector), disconnect
the supplied FM antenna.
Center unit
About the cooling fan
A cooling fan is mounted on the rear panel of the center unit to
prevent abnormal temperature inside the center unit, thus assuring
normal operation of the unit. The cooling fan automatically starts
rotating to intake external cool air when the internal temperature
goes up.
For safety, observe the following carefully.
• Make sure there is good ventilation around the center unit. Poor
ventilation could overheat and damage the center unit.
• DO NOT block the cooling fan and the ventilation openings or
holes. (If they are blocked by a newspaper or cloth, etc., the
heat may not be able to get out.)
• DO NOT touch the speaker cords to the cooling fan.
