Installing the MC3 System
Hardware Installation Guide 23
The USB cable is connected to the dock at the factory and is secured with a cable
tie. DO NOT remove this cable tie or unplug the USB cable from the dock. The
cable tie helps ensure a secure connection and should never be disconnected. The
cable tie also ensures that the correct COM port is used for GPS communications
with the Mobile Interface software. Using a different USB port will prevent the
MC3 radio from communicating properly with the software.
2. Plug the round end of the USB cable into the MC3 radio by pulling the connector
sleeve back, plugging the connector in to the receptacle, and releasing the sleeve.
Attaching Older GoBooks to the MC3
This section explains how to connect older GoBook models to the MC3.
GoBook III This GoBook can be attached directly to the vehicle dock, mounted on a
pedestal by the driver or on a sled (similar to the GoBook XR-1).
GoBook MAX This GoBook must be attached to the vehicle dock on a pedestal
mount; no sled option is available.
Attaching the GoBook III to the Vehicle Dock
You can attach the GoBook III to a vehicle dock on a sled or pedestal near the driver. The
vehicle dock must be installed on the sled or pedestal before attaching the GoBook III.
