Installing batteries in the remote
controller

Since the remote controller will be used for
many of this unit s control operations, you
should begin by installing the supplied batte­ries.

1.Turn the remote controller over and slide
the battery compartment cover in the direct­ ion of the arrow.

2. Insert the batteries(AAA,R03,UM-4 TYPE)
according to the polarity markings on the
inside of the battery compartment.

3.Close the battery compartment cover.

Notes about the remote controller

Batteries replacement

If you find that the remote controller must be used
close to the main unit, the batteries are weak.
Replace both batteries with new ones.

Notes
Use AAA,R03,UM-4 batteries.

Be sure the polarities are correct.(See the illu­ stration inside the battery compartment.)
Remove the batteries if the remote controller
is not used for an extended period of time.
If batteries leak, dispose of them immediately.
Avoid touching the leaked material and contact
with clothing, etc. Clean the battery compartm­ ent thoroughly before installing new batteries.

Remote controller operation range

Within approximately

6m(19.7feet)

Notes
The area between the remote controller and

the main unit must be clear of large obstacles.

Do not expose the remote control sensor to
strong lighting, in particular an inverter type
fluorescent lamp. Otherwise, the remote
controller may not work properly.If necessary,
position the main unit away from direct lighting.

BASIC CONNECTIONS

Assuming you have a DVD, the following steps will help you quickly set up your new receiver. If you have

more electronic components, consult the table of contents or index for the page on which to find the

connection description that best suits your situation.

the wires(bought from store ) and jacks have been color-coded to assist you.

1.Using an audio wire with red and white connectors, connect the audio OUT jack on the back of

your stereo DVD to the audio IN jack under the DVD heading on the back of the receiver.

2.Using the video cable with yellow connectors, connect the video OUT jack on the back of your

DVD to the VIDEO IN or VIDEO INPUT on the back of your TV. If there are multiple video jacks

on the back of your TV, use VIDEO 1 .

FIRST THINGS FIRST

CONNECTING THE SPEAKERS

CONNECTING THE WIRES

CONNECTING THE MAIN SPEAKERS

The two main speakers should be set between six and 10 feet apart. Putting the speakers any closer or

any farther apart may result in distorted sound.

The speakers should also form a 45 degree angle to the central listening point in the room, creating a

triangle of listening enjoyment.

CONNECTING THE ANTENNAS

The AM and FM antennas connect to the AM and FM

terminals on the system's back panel. They must

be hooked up for you to receive clear reception.

Uncoil the antenna wires and locate the bare ends.

Press down on the tab to open the terminal and

insert the wire. Snap the tab closed.

After connecting the antennas, extend them to

their full length and adjust their positioning for

better reception.

Method 1

Method 2

1.Loosen the knob.2.Insert the bare wire.[Remove

approx.5mm(1/4 ) insulation from the speaker

wires]. 3.Tighten the knob and secure the wire.

Or you also may use banana plug.

Speaker Polarity

When connecting the speakers, make sure the

polarities("+" speaker wire to "+" on the receiver)

of speaker wires and terminals are matched.

If the cords are reversed, the sound will be distort-

ed and will lack bass("out of phase"effect).

NOTE:

Do not let the bare speaker wires touch each

other or any metal part of this unit. This could

damage this unit or the speakers, or both.

Connect the speakers terminals to your speak-

ers with the wire of the proper gauge

(keep as short as possible).if the connections are

faulty,no sound will be heard from the speakers.

FIRST THINGS FIRST

CONNECTING FOR POWER

Make sure you connect all your other electronic

components and the speakers before plugging

your receiver into the outlet.

Plug the power cord in the wall outlet, matching

the wide blade of the plug with the wide slot in

the outlet. Be sure to insert the plug completely.

USING HEADPHONES

To listen privately through your audio system, use the PHONES jack on the receiver. How ever, make sure

you turn down the volume before you put on the headphones.Increase the volume to the desired level after

headphones are in place.

Hearing Comfort & Well-Being

Do not play your headset at a high volume.

hearing experts advise against continuous

extended play.

If you experience a ringing in your ears,

reduce volume or discontinue use.
