Notes

•When the camera input is selected, sound is not emitted.

•Each item can be set at every input source except the camera input, but the settings made at one input source are applied to all input sources as shown in the table. The sound volume can be adjusted for each input source except the camera input.

•The adjustments or settings made are memorized automatically when the power is turned off by pressing the ON/STANDBY button. If the power cord is unplugged or if a power failure occurs while the projector is on, the adjustments or settings are not memorized.
