Epson EL 486UC 사용자 설명서

If you are installing a 486SX/33, a 486DX/33, or a 486DX2/66

processor, you must replace the existing oscillator with an

Ecliptek 33 MHz oscillator (EC1100). Follow these steps to

remove the existing oscillator and replace it with the new

oscillator:

1.

Use the illustration on page 3-5 to locate the oscillator on the

system board.

Use scissors or a small knife to cut the tie wrap securing the

oscillator to the system board, then discard the tie wrap.

Using your fingers, pull the oscillator straight up and set it

aside.

Remove the new oscillator from its package, being careful

not to touch the pins.

Position the oscillator over the socket. Make sure pin 1

(identified with a dot) aligns with pin 1 on the socket. A

triangle traced on the system board identifies the side of the

socket containing pin 1.
