If your Remote Display does not have the front cover accessible push button C&C mode switch, an optional C&C sealable switch kit (P/N 330020-507) is available. The switch replaces an internal jumper (between terminals 16 GND and 17 CSS) and is installed on the front panel of the Remote Display. The installer will have to drill a hole in the front cover of the display for this switch assembly, then install the switch as shown in Figure 33. A template for locating the C&C mode switch hole is provided in Appendix B of this manual. These bolt heads have been drilled through for sealing wire.
