Turning Up or Down Volume
Sound level from the AUDIO OUT terminal can be adjusted.
Important:
• Do not turn up the volume to the maximum level on the external speaker system connected to the AUDIO OUT of the projector.
Doing so may produce an unexpected, loud sound at the time of turning on or off the projector, causing damage to your hearing.
When adjusting the volume on the external speaker system, set volume level of the speaker system to less than half its rating and
adjust the volume on the projector to get appropriate sound level.
TIP: When no menus appear, the ◀ and ▶ buttons on the projector cabinet work
as a volume control.
NOTE:
• Volume control is not available with the ◀ or ▶ button when an image is enlarged
by using the D-ZOOM (+) button or when the menu is displayed.
