Note
• When set to “LOW”, it is possible to
reduce power consumption, reduce
operating noise and extend lamp
service life.
• “LOW” is set automatically when Long
Life Lamp Units are used.
• If any of “SINGLE”, “LAMP 1” and “LAMP 2” has
been selected, when a currently lit lamp expires, or
is turned off due to the elapsed time of lamp
lighting exceeding 1500 hours (with the lamp
output set at “HIGH”), the other lamp will be turned
on.
If “DUAL” has been selected, when either of the
two lamps expires, or is turned off due to the
elapsed time of lamp lighting exceeding 1500
hours, the other lamp with elapsed time not
exceeding 1500 hours continues lighting.
Further, if the elapsed time exceeds 1500 hours
for both lamps, the projector will enter a standby
state.
• If only one lamp is mounted, select “LAMP 1” or
“LAMP 2” according to the relevant lamp unit.
In “LAMP 1” or “LAMP 2” mode, if the
corresponding lamp is not installed, the other lamp
will turn on.
• If the lamp selection is changed, picture is muted
during lamp switching execution. (7-25sec.)
This time period is 4 000 hours when Long Life
Lamp Units (page 100) are used.
