The USB keyboards contain three internal USB heaters that prevent damage when operating in condensing environments:
  • Low - this heater operates with the standard USB cable, and turns on when the temperature is below 20° C (68° F).
  • Normal - this heater operates with the Y-cable, and turns on when the temperature is below 15° C (59° F).
  • High - this heater operates with the Y-cable, and turns on when the temperature is below 5° C (41° F).
