Chapter 1 Using the MC3 System
Connecting the GoBook XR-1 to the MC3
The MC3 rides in a harness that attaches to bucket- or bench-style passenger seat. The sled
for the GoBook XR-1 is equipped with a dock for the computer and a junction box for
power connectors (the junction box must be attached to the sled prior to use). The sled
should be mounted on the seat before the MC3 radio is attached. The MC3 must be
mounted high enough on the seat so that the right side ports on the GoBook are accessible,
as shown in the example below.
