ers. Only use these bulbs. Hold the new halogen bulbs
only with a clean, dry towel. This increases the service

When changing the bulb, the bulb socket contacts are

Before replacing the bulb, ensure that the appliance
is switched off in order to prevent a potential electric
shock.
Also unplug the appliance from the mains or switch
off the circuit breaker in the fuse box.
