4.3 Changing the bulb
Any deposits of fat from the skin on a halogen
lamp bulb cause the glass to become fogged
and significantly reduce the life of the bulb.
• Do not touch the glass bulb of the halogen
lamp with fingers.
• Remove the securing screws and remove
the lid of the casing.
• Take out the defective halogen bulb.
• Holding the replacement bulb with a cloth or
other protective material, push the connecting wires into the socket.
• Screw the lid back on.
