Fig. 32
When switching on from stand-by, the projector will turn
on the lamp (flashing green LED); after a brief warm up
period the image will be displayed (green LED on). The
input automatically selected will be the last one memorised
prior to switch off
(Fig. 32) .
8.2 SWITCHING OFF AND RETURNING TO STAND-BY
By remote control: press
By keyboard: press key
When switching off, the projector goes in to stand-by (red
and green LED flashing) memorising the input selection
at the time of switch-off.
The fans will continue to work until the lamp has cooled
down. They will stop automatically after this period.
8.3 FAILURE OF THE LAMP TO LIGHT
Switching on from stand-by. If the lamp fails to come on
(the projector will automatically make five attempts), an
error will be registered by a flashing red LED. This can be
reset by switching the power switch to position O.
9. DESCRIPTION OF CONNECTIONS
To obtain the best performance from your projector, we
recommend the use of good quality “video cables” to the
various signal sources (75 ohm Impedance).
Poor quality cables will cause inferior picture performance.
For optimum connectivity we recommend you follow these
simple steps:
- With exception of coaxial RCA/Phono type connectors,
always double-check that the plug is inserted the correct
way round to avoid damaging the plugs or the sockets
on the projector
(Fig. 33) .

- Remove cables by the plug and do not pull on the
cable itself.
- Avoid tangled cables.
- Position the cables carefully to avoid a trip hazard -
especially in low light areas (Fig. 34) .

You may experience difficulties switching on
the projector shortly after turning off into stand-
by mode. This is not a fault. The lamp is still
too hot for the switch-on procedure to take
place.
Wait a few minutes before turning on again (position I),
this will allow the lamp to cool down to the correct tempe-
rature.
The life of the lamp is dependant on the number
of times the projector is switched ON and OFF.
