Read this manual
Read all chapters of this manual carefully before switching on the projector. This
manual provides basic instructions for operating the CRYSTAL4-SH projector.
Installation, preliminary adjustments and procedures that necessitate the removal of
the glass cover and the contact with electrical components, must be performed by
authorized trained technicians. To ensure safe operation and long term reliability use
only the power cord supplied by the manufacturer. Observe all warnings and
precautions. Keep the manual for future consultation.
Do not touch internal parts of the projector
Inside the housing there are electrical parts carrying dangerously high voltages and
parts operating at high temperature. Never open the housing. Entrust all servicing and
repair work to a SIM2 Authorized Service Center. Opening the housing voids the
warranty.
Disconnect the projector from the power supply
The device that disconnects the projector from the electrical outlet, is the power plug.
Ensure that the power cord plugs and the electrical outlets are easily accessible during
installation operations. Pull the plug, not the cord, to disconnect the projector from
the electrical outlet. Use only the specified power supply. Connect the projector to the
electrical supply with rated voltage of between 100-240 V AC, 50/60 Hz and equipped
with a protective earth connection. If you are not sure of your domestic electrical
outlet, contact an electrician. Take care to avoid overloading the power socket and any
extension leads.
Switching the projector off
Pay attention to the switch off procedure for the projector. The projector must always
be brought back to the standby state to allow the projector to carry out the cooling
procedure. Should this not happen, for example due to a power cut, the projector may
enter a state of protection that leads to switch-on being blocked. This block will last
until the internal components of the projector have completely cooled down. Allow 90
seconds for the projector to cool down.
Be careful with cables
Make sure cables are routed so that people are not impeded or become a trip hazard.
Keep all cables away from children. Install the projector as close to the wall socket as
possible. Avoid stepping on power cords, make certain they do not become tangled,
and never jerk or tug them; do not expose them to sources of heat, and make sure
they do not become knotted or crimped. If the power cords become damaged, stop
using the projector and request the assistance of an authorized technician.
Disconnect the projector from the electrical outlet during storms and when not in
use
To prevent damage from lightning strikes in the vicinity, disconnect the projector
during storms or when the projector is going to be left unused for a long time.
