Main Board Re-install
Re-install the main board in the housing before you install the
SC board.
____1) Replace the main PCB board assembly by tilting the back
up and sliding it toward the front into the PK-232 housing.
Make sure all the leds on the led board, the threshold
control and the DCD led fit cleanly into their holes in the
front panel.
____ 2) Replace the nut and washer from the bushing of the
threshold control. Do not tighten the nut until after
completing the next step.
____ 3) Replace all the screws on the bottom of the PK-232
housing that hold the main board in place. There may be 6
or 7 screws, depending upon the model of the PK-232.
____ 4) Tighten the threshold control nut.
____ 5) Replace the threshold control knob on the front panel.
____ 6) If you have a PK-232MBX with a daughter board, replace
the MBX board. Do not bend the pins on the bottom of the
MBX board. Reconnect the reset wire from the main board
to the MBX board.
____ 7) If you have a OVL LED assembly installed, plug the IDC
connector into the header next to the red LED on the DSP
board.
