Setup, Interfacing and Adjustment

This section of the manual contains everything you should need to know to get your repeater

Step #1: Check the Packing List

Your package should contain the following items:

(1) RLC-3 Repeater Controller and cabinet

If any of these parts are missing, contact Link Communications Inc.
