12. USB CABLE CONNECTION
The function permits to duplicate the screen from a smartphone or tablet equipped with an IOS
system, by connecting the terminal to the projector using a USB cable with data connection to the
USB1 input.
Immediately after connection, the terminal will request authorization to send images, which must be
granted; through the duplicate screen function, it will be possible to obtain the reproduction of the
display: since the image is vertically developed, rotate the device in landscape mode.
13. SHUTDOWN
To switch off the projector, press twice the power off key on the control keyboard (chap. 4 n. 16) or on
the remote control (chap. 4 n. 1).
14. MAINTENANCE
The projector does not require special maintenance which involves components or consumable
replacement: normal maintenance consists only in cleaning operation. All maintenance must be done
with the device switched off, cold and disconnected from the mains: if the projector has been used
recently, wait at least one hour after shutdown.
It is necessary a periodic cleaning of the air intakes: use a soft brush and absolutely avoid the vacuum
cleaner. The lens normally do not need cleaning: possibly, remove the dust with a can of compressed
air from a considerable distance. For the external case cleaning, use a damp non-abrasive cloth,
avoiding solvents or excessively aggressive detergents. Wait for complete drying before connecting
again the device to the mains.
Only if the image has dark areas there is a possible presence of dust on the internal mirror: its cleaning
is possible through the appropriate door on the projector bottom; however, it is recommended that this
operation should be carried out by a qualified technician only.
