Setting the Switchbank
To set a switch to on, use a ballpoint pen or similar pointed tool and push the
switch down. Take care that only one switch is on (down) and that the remaining
three switches are off (up). See Figure 6-1, “Dip Switch Locations.”
Notice that each switch can represent either a numeric LIM or an alpha LIM,
depending on the expansion module. For instance, setting the leftmost switch to
on would assign LIM 1 to a data module; the same switch settings on a voice
module would assign LIM B.
