AUTOMATIC LAMP CHANGER
The Ceiling Visualizer is fitted with an automatic lamp changer.
If one lamp fails, there is no need to replace it immediately, as the automatic lamp changer
automatically switches to the second (spare) lamp. When the unit changes lamps there is an on-screen
message saying: "Changing lamp".
When switching on the unit the Visualizer checks if both lamps are working. If one lamp fails there will
be an on screen message for a couple of seconds displaying "Change lamp".
This prevents a user from forgetting to change a defective lamp.
If a lamp is not fully defective but worn out and as a result the light output is quite weak, you can switch
manually to the second lamp by pressing the EXT/INT-key (#24) for 2 seconds.

Only use long life 12 V/100 W halogen lamps (socket: GY 6,35).
Type: Osram HLX 64623, Ansi EVA, LIF M/28, NAED 54052 etc.
These are relatively inexpensive standard OHP lamps.
THERMOSTAT
If the unit gets too hot (improper ventilation or air extraction) a built in thermostat will switch off the light
of the Visualizer. Verify that proper ventilation and air extraction is available and allow the unit to cool.
1. Turn the unit off (#26) and disconnect the power cord (#28)!
2. Press the release button and swing the unit downwards.
(see figure 1 and figure 2)
3. Place a lock pin to fix the folding mechanism (see figure 2)
pin diameter: 2,5mm and length: 40mm
4. Release the quick lock by turning and lift up the lid.
(See figure 2)
5. Change the lamp (or both lamps) (see figure 3)
Before changing the lamp allow it to cool or use a cloth to
avoid burning a finger!
When inserting a new lamp into the socket use a cloth to
prevent fingerprints on the lamp!
