2.2. Getting Started
Plug the mains cable into a conventional, properly earthed 240 Volt 10 Amp mains power
socket-outlet and switch it on. The green Standby indicator (B) will illuminate and the
CWS4000 will beep when power is connected.
Ensure that air is not prevented from entering the inlet slots at the sides by blankets or other
objects.
Remove the warming blanket from its packaging. Unfold the warming blanket and place it over

or 46°C temperature settings, place your hand under the warming blanket to confirm that the
CWS4000 is supplying warm air. Place a sheet or blanket over the inflated warming bianket to
