Operating
Spread the blanket out at 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
rmly 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!
Make sure, the connection cable of the control unit is properly
connected to the plug of the heated underblanket. Plug the
unit into the mains outlet and move the slider control
2
from
position 0 to position 1. The power LED
1
will light up in
green.
After a few minutes you will be able to feel the heated
underblanket getting noticeably warmer. If you require
a higher temperature setting, move the switch to the next
positions 2 or 3 or the maximum heat setting, position 4.
If the heated underblanket gets too hot for you, move the
slider back to position 3, 2 or 1. After a short time, the heated
underblanket will cool down.
The heated underblanket may cool down after a short period
of time. This is normal. The fast re-heating according to the
setting will follow immediately.
To switch the unit off, move the switch back to position 0. The
power LED
1
will go out, indicating that the unit is switched
off. Unplug the unit from the mains outlet.
Move the switch to position 1 for any continuous use. The
heated underblanket will switch off automatically after approx.
180 minutes of continuous use.
To switch it back on again, move the slider switch to position
0 and then back to the desired heat setting.
Unplug the unit from the mains outlet once you have nished
using it.
Troubleshooting
If there is no function at all after switching on the heated
underblanket (power LED
1

the mains plug is correctly plugged in the mains outlet. If this
is the case, the heated underblanket is defect. Please do not
use the heated underblanket and contact the service center.
