4Push the attached dust covers over the exposed ends of the connectors.

5Store the display unit in a dry clean place, such as the optional Northstar carry bag.

Replacing the display unit

1Remove the dust covers from the connectors. Plug the connectors into the back of the display unit:

Match the connector’s color to the socket color.

Insert each connector and turn the locking collar clockwise until it is finger tight.
