11 MAINTENANCE
 
The projector needs very little maintenance in order to function properly.
11.1 
GENERAL
 
Use a damp cloth to wipe off dust on the exterior. Clean the lens with a
damp, non-abrasive cloth, using just water or a standard lens cleaning
solution available from photographic dealers.
 
Vacuum the air inlets periodically, especially when build-up
of dust is observed. This will ensure cool operation of the
unit.
 
 
Do not scratch the lens surface. Use the lens cap when the projector is not
in use for added protection. Remember to remove the lens cap before
operating the unit!
11.2 
LAMP REPLACEMENT
 
The projector is using a custom UHP-lamp for illumination. The lamp is high
pressure when hot (operating or immediately after switch-off). Lamp
pressure is normal when cold.
 
 
A lamp timer is available in the menu system under HELP, ABOUT, that
may be used to track lamp operating time. The user may reset the timer.
 
Disconnect the power cord before opening the lamp lid to
change the lamp.
1.  To change lamp, remove the lamp lid by pressing in the snap lock and
lifting up (see illustrations below). A safety switch will cut off the power
supply to the lamp completely.
2.  Unscrew the 2 safety screws holding the lamp holder, fold out the
handle and pull out the old lamp holder.
3.  Insert a new lamp holder/lamp all the way until it positively stops, fold
the handle and reverse the procedure above.
Use only original lamp and holder as specified. The lamp is
individually adjusted with the holder to maintain optimum
illumination. Replacement using a different lamp may result
in poor illumination, malfunction (potentially explosion) and
will void any warranties.
