This slide shows the Input Menu, and explains the symbols that appear on
the menu screen.
The menu system is similar to the Sirius-PJ1, but the contents are not exactly
the same. See ‘5. Using On-Screen Menu’ in the user manual for full details
of the user menus.
For details of all functions, see the user’s manual.
High Altitude Mode: The fans operate at a higher speed in this mode. Use
this when the projector’s location is more than 1500 m (5500 ft) above sea
level (otherwise, the projector could overheat and shut down automatically). If
you use Eco Mode, also use High Altitude Mode if the projector’s location is
more than 1000 m (3200 ft) above sea level.
Also, if you use high altitude mode at less than 1500 m (5500 ft)
above sea level, the projector could become too cool, causing images
to flicker. Switch [FAN MODE] to [AUTO].
High Temperature Alert: High temperature detected inside the projector, Eco
Mode is enforced
If the projector overheats, it shuts down automatically. Wait a few
moments then turn back on again.
