With the medisana HU 662 heated under blankets you can gently warm and relax your whole body. Using the blanket stimulates the circulation in areas of tense muscle and promotes a sense of well being after a strenuous day. The heated Underblanket provides a pleasantly warm bed, allowing you to relax and get to sleep quickly. Spread the blanket out flat on top of the mattress. There are four rubber bands sewn onto the heated Underblanket. Use these bands to tighten the heated Underblanket over the corners of the mattress. Make sure that the electric Underblanket is firmly strapped to the mattress in both directions and that it will not crease while it is being used. Spread a bedsheet on top of it. This allows the Underblanket to release its heat in the best way possible. Check it is in the correct position before going to bed! The blanket may only be used when it is spread out flat. The heated Underblanket features an electric temperature control that regulates the temperature according to the chosen setting.


We recommend switching on the heated Underblanket 30 minutes before going to bed.
Plug the blanket into the mains outlet and move the selector switch 2 from position 0 to position 1.
The power LED 1 will light up. When switching up and down the different levels, the indicator lamp flashes twice briefly and then comes on permanently. You will feel the blanket gradually warming up. This will be even more noticeable if it is covered with a quilt. If you require a higher temperature setting, move the switch 2 to the position 2, 3, 4, 5 or to position 6. Should the blanket get too warm for you, slide the switch back to position 5, 4, 3, 2 or to position 1.
Level 3-6 of the device is intended for heating up, only level 1-2 is for continuous operation. After approx. 180 minutes continuous operation the heated Underblanket automatically turns off.
To switch off the blanket, return the switch 2 to position 0.
The power LED will go out, indicating that the unit is switched off. Now unplug the blanket from the mains outlet.
