When the KIT is too hot or too cold to charge, the red slash battery symbol appears in the top, right corner of the screen. To fix this issue, do the following:
- Unplug and power off the unit.
- Wait until the unit has cooled down to normal use temperatures.
Note: Charging only occurs at temperatures between 32°F (0°C) and 104°F (40°C).
- Plug the unit in and begin charging again.
