Epson equity 320sx plus Manuel D’Utilisation

The illustration below shows the locations of the jumpers on

your computer’s main system board.

A jumper’s setting is determined by where the jumper is placed

on the pins. It connects either pin A and the middle pin

(position A) or pin B and the middle pin (position B), as shown

below.

To move a jumper from one position to the other, use

needle-nose pliers or tweezers to pull it off its pins and gently
move it to the desired position.
