The following procedure explains the front speaker assembly. The 
assembly of both the front and surround speakers are done in the 
same manner.
NOTE

surround speakers assembly.

 Prepare a Phillips screwdriver (not supplied).
 Take care not to drop the base plate while assembling; otherwise, 
it may cause damage to the floor or injury.

NOTE
• Although the satellite speakers and the powered subwoofer are magnetically shielded, the TV screen may appear mottled. In this 
case, keep enough distance between the speakers and the TV.
 The speakers are magnetically shielded to avoid color distortions on  TVs. However, if not installed properly, they may cause color 
distortions. So, pay attention to  the following when installing the 
speakers.
– When placing the speakers near a TV set, turn off the TV’s main  power switch or unplug it before in stalling the speakers. Then wait 
at least 30 minutes before turning on the TV’s main power switch 
again.
Some TVs may still be affected ev en though you have followed the 
above. If this happens, move the speakers away from the TV.
 Place the satellite speakers on a flat and level surface.
 Be sure to place the powered subwoofer to the TV’s right. If you place  the powered subwoofer to the TV’s left, keep sufficient distance 
between them to prevent the TV screen from appearing mottled.
For TH-M606/TH-M603 only:
 Do not lean against the satellite sp eakers, as the speakers could fall 
down or break, possibly causing injury . Especially be careful not to 
let children lean against them.
 You can get better picture qu ality in the order — Component 
video > S-video > Composite video.
 Distortion of picture  may occur when connect ing to the TV via a 
VCR, or to a TV with a built-in VCR.
 You need to set “MONITOR TYPE” in the PICTURE menu  correctly according to the  aspect ratio of your TV. (Apg. 39)
7 To connect a TV equipped with the component video 
input jacks
NOTE
 If your TV supports progressive  video input, you can enjoy a high 
quality picture by setting the pr ogressive scan mode to active. 
( A pg. 20)
 If the component video input jacks of your TV are of the BNC type,  use a plug adapter (not supplied)  to convert the pin plugs to BNC 
plugs.
 The component video signals can  be output only when you select 
“DVD” as the source to play. ( Apg. 19)
