Setting the Jumpers
The illustration below shows the locations of the jumpers. You’ll
need to remove the subassembly to see all of the jumpers
(described later in this section).
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. Be careful not to lose the jumper.
