How do I switch between the different modes of the Hotspot Blanket?

You switch between the different modes of the Hotspot Blanket by first pressing the O in the Fatboy label to turn the Hotspot on. You will now see 1 red LED light. Press it again to activate the next mode (2 red LEDs will now light) and again for the third and warmest mode (3 red LEDs will now light).

If you press the O button again, the Hotspot Blanket will turn off (all 3 red lights will go out)
