Appendix C: Power Cycling the Controller
If your controller is unresponsive, and the LEDs unlit, and the steps outlined in the troubleshooting guide
didn’t resolve the problem, perform the following steps:
1. Use an ESD wrist strap connected to a suitable electrical ground. If one is not available, avoid
touching any electronics within the enclosure unless required by this process.
2. Open the controller lid by removing the four screws in the enclosure corners. (See Figure 20:
Controller Lid).

3. Unplug the battery and WAIT 3 or 4 MINUTES to allow the capacitors in the circuit to drain their
residual charge.
