Replacing Assemblies

To remove and replace the front panel and keyboard

To remove and replace the front panel and keyboard

1Using previous procedures, remove the following assemblies:

•Handle

•Rear Feet

•Cover

•Disk Drive

•Power Supply

•Main Circuit board

2Remove the four screws connecting the front panel.

3Slide the front panel assembly out the front of the instrument.

4Slide the spacers out the front of the instrument to remove them.

Be careful not to lose the copper ground strips on the spacer.

When installing the spacer, insert the pins of the spacer in the appropriate holes in the chassis. You can hold the spacer in place while installing the front panel by holding it with your finger through the disk drive mounting slot in the chassis.

5Remove the RPG knob by pulling the knob off the RPG shaft.

6Disassemble the front panel assembly by lifting the keyboard circuit board away from the front panel.

7Lift the elastomeric keypad out of the front panel.

8Reverse this procedure to assemble and install the front panel assembly.

When assembling the front panel, check that the holes in the elastomeric keypad and the keyboard circuit board align with the pins on the front panel.

To remove and replace the intensity adjustment

1Using previous procedures, remove the following assemblies:

•Handle

•Rear Feet

•Cover

•Rear Panel

2Disconnect the intensity adjustment cable from the CRT driver board.

3Using a nut driver, remove the hex nut attaching the intensity adjustment to the chassis.

4Slide the intensity adjustment assembly toward the front and up out of the instrument.

5Reverse this procedure to install the intensity adjustment.

When installing the intensity adjustment, check that the keying tab on the adjustment aligns with the keying hole in the chassis.
