My Hotspot's 4 battery LEDs flash rapidly from left to right, what to do?

No worries if your Hotspot Blanket's battery LEDs flash! Your Hotspot has a built-in thermostat. Once the maximum heat is reached, the Hotspot will automatically switch itself off to prevent overheating.

After the Hotspot's temperature has dropped a little, you can turn it back on and continue using it in the medium setting (setting 2) for the most comfortable user experience

Mode 3 (HOT) is for short-term use only.
