Installation Procedure
As you install components and reassemble your K3, be sure all the screws are in place
and secure, but do not over tighten them. Failure to tighten all screws may result in poor
shielding of sensitive components, resulting in possible noise or birdies in the receiver as well
as other difficult-to-trace problems.
Removing the Top Cover
Disconnect power and all cables from your K3.
Remove the nine screws to free the top cover as shown in Figure 1. After the cover is open, lift it gently to
reach the speaker wire connector. Unplug the speaker then set the top cover aside in a safe place.
Whenever you remove screws from a panel, if one screw seems too tight to loosen
without damaging it, first loosen the other screws then try again. Sometimes one screw
binds in its hole when the other screws are tightened.
