When brightness is low after the lamp replacement, the brightness may increase if you adjust the
position of the condenser lens.
You don’t have to adjust it at initial setting since the position has been adjusted optimally with a
built-in lamp at factory.
[Procedure]
1. After turning on the main power, wait until the brightness becomes stable (about three minutes).
2. To access the optical unit, open the screen (chapter 1.2.7.1, on page 21) in
