CAUTION
Risk of minor burns by hot lamp module.
• Switch off the device first and unplug the mains cable
• Do not touch hot parts or surfaces
• Let the lamp module cool down safely
• Do not touch the bulb glass
To replace a defective lamp module, proceed as follows:
•
Switch off the instrument and unplug the mains cable. Let it
cool down safely!
• Loosen the two screws on the left rear of the instrument
approximately 3-5 turns.
• Remove the cover.
For easy release of the housing slightly tilt the back part away
from the screws. Then pull out the housing towards the rear side
of the instrument. There is a built-in sensor to record the opening
of the housing.
A safety tack ensures that the lamp remains in
the correct position.
• Slide the safety tack to the upright position (counterclock-
wise).
• Pull the metallic housing with the primary lamp out of the
lamp unit.
• Exchange the primary lamp source with a new lamp by
removing it from the gray plug and connect the new primary
lamp source to this plug.
• Insert the new lamp into the lamp unit and slide the safety
tack back to the horizontal position until a metallic click sound
is audible, which indicates the right position. Make sure that
the gray plastic plug is in a vertical position.
• Secure the housing of the lamp unit with the two screws on
the back side of the unit.
