Removing the Old PCBA
N OTE : When disassembling the unit, be sure to save all the hardware, as it will be needed when the unit is
re-assembled.
1. Loosen the four screws at the corners of the front panel, and pull the plug-in amplifier from the
enclosure. All maintenance work from this point on should be performed at a work bench with the
operator properly grounded to avoid static discharge.
2. Loosen the four chassis screws (Phillips) on the top and bottom of the unit.
3. Carefully slide the chassis to the left, and separate it from the front panel.
CAUTION
The power supply harness inside is short; do not pull it apart abruptly.
4. Remove the power supply harness from J6 on the Model 69241 PCBA by pressing the tab on the
locking connector.
