switch to ensure your safety. The device will automatically
switch off if excessive heating takes place. When this hap-
pens, switch off the appliance for a few minutes by remov-
ing the plug from the power supply socket and allow the
appliance to cool. The appliance can be reconnected to the
mains power supply again after approximately 20 minutes.
