To prevent accidental power-down of a C3 unit, the process to switch off the unit consists of two presses of the power button, with specific timing.
To power down a C3:
- Remove all power sources from the C3 (plug pack or solar panel input).
- Briefly press and release the power button
- Wait one second
- Press and hold the power button until the C3 issues one long beep and all indicator lights turn off
- Release the power button and confirm that all C3 indicator lights are off, signifying that the unit has powered down
