4.6 Auxiliary Header
An 8-position auxiliary header, J4, is located below the AC/DC power switch.
Two-pin shunts should only be used for special situations. The shunts should
be stored vertically on the right-hand side of the header when not in use, as
shown. When a shunt is used, it will be installed horizontally across 2 pins.
