Use only original spare parts! If this is not done, it can lead to personal injury and material dam-
age. Repairs that are not described in this document must only be carried out by authorized
workshops!
Before opening the device, always pull the power plug!
Do not touch the quartz envelope or the inside of the lamp reflector! This drastically shortens the
life of the bulb. Grasp the bulb only at the outside of the reflector or close to the contact pins. Al-
ways let hot bulbs and their environment cool off sufficiently.
