R/C Operation

Selecting the R/C Input Mode

The R/C Input Mode is the factory default setting.

If the controller has been previously set to a different Input Mode, it will be necessary to reset it to the R/C mode using one of the following methods:

•Restoring the factory defaults by pressing and holding the Program and Set but- tons while powering on the controller until the LED display flashes

•Setting the “I” parameter to the value “0” using one of several methods described in the chapters “Configuring the Controller using the Switches” on page 175, “Using the Roborun Configuration Utility” on page 181, and “Accessing & Changing Configuration Parameter in Flash” on page 147.
