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 and set the top cover aside in a safe place.

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 Preventing ESD Damage

page 4 for more information.

On the rear of the K3, remove the large blank panel above the GND screw. This panel will not be used

again, but the screws will be needed to mount the KPA3 cooling fans. (If you are installing the KPA3 as part of

building your K3 kit, this panel may not be installed.). Newer panels have a hole marked ANT3 for the antenna

connection to the optional K144XV 2-meter module. If you do not have the K144XV option, a plastic plug will

fill this hole. Remove the plug or the antenna connector. To prevent accidental short circuits, either tape the

metal end of the BNC connector or unplug the cable from the K144XV module and remove it entirely for now.

Turn the K3 upside down and remove the bottom cover(s) as shown in Figure 2. Note that, if you are

finishing the KPA3 installation after assembling your K3 kit, only the rear portion of the bottom cover need be

removed.
