4. Remove the 0



resistor by heating both sides simultaneously with

soldering irons. Separate the resistor from the board by gently
pressing the tips of the soldering irons together.

5. Save the resistor in order to re-enable the On/Stdby switch. Again,

heat damage may prevent the resistor from being re-installed.

6. Replace the mainframe cover and rear panel. Make certain that all ten

mainframe cover screws and all 14 rear panel screws are secured.
