Operating the projector continuously
1. If the projector is to be operated continuously for one week, use the dual-lamp optical system's alternat-
ing lamp operation (lamp relay) function. The projector cannot be operated continuously one week in
dual-lamp mode. Allow a minimum of two hours per day of non-operation time for each lamp if the pro-
jector is to be operated continuously for more than one week.
2. The lamp replacement cycle duration becomes shorter if the projector is operated repeatedly for short
periods.
