conditions

connections

1. Remove the protective dust cap from the bottom of the desiccant pack, if applicable.

2. Remove the small desiccant (if present) from the RuggedCable by grasping the

knurled (textured) section of the cable connector in one hand and the desiccant in the

other. Twist in opposite directions to unlock the desiccant from the cable.

3. Attach the large desiccant to the Twist-Lock connector on the cable.

Attaching cables and accessories is a simple matter of mating the Twist-Lock

connectors. This is easy after you've done it once or twice. For detailed steps and

photographs, see the product Quick Start Guide, or the Operator's Manual.

4. Remove the red dust cap to allow air to reach the cable's vent tube, if applicable.
