INTERNAL SWITCHES, JUMPERS AND ADJUSTMENTS
There are several internal switches, jumpers and an
adjustment that affect operation. These are described below.
To gain access to the switches, jumpers and the adjustment,
disconnect all power and line connections. Remove two
screws from the top of each side and two screws from bottom
of each side. Switch, jumper and adjustment locations are
shown in Figure 2.
