Installation Procedure

Removing the K3Top Cover and Chassis Stiffener

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.

Figure 1. Removing K3 Top Cover.

CAUTION:

Touch an unpainted metal ground or wear a grounded wrist strap

before touching components or circuit boards inside the K3. See page 4 for more

information.

Remove the stiffener bar that runs from side to side across the top of the K3 chassis. This is the bar the

three screws across the center of the top cover thread into. The bar is held in place by a single screw at each side

and, if the KPA3 100 watt option is installed, by two screws attaching it to the KPA3 shield. Some KPA3

shields have PEM nuts permanently attached to the shield for the screws. Others use ordinary nuts that must be

removed with the screws and lock washers.
