Adjusting Volume
When the volume is lower than -30 dB, an increase or decrease of 1 dB
occurs each time the up arrow or the down arrow is pressed and released.
When the volume is higher (louder) than -30 dB, the incremental change
is 0.5 dB.

and then flashes to indicate that the Remote Panel is in Volume
Adjust mode.
2. Press a Destination key(s) to select the destination(s) that requires
volume adjustment.
The Destination key(s) illuminates, along with the Up Arrow
(Macro) and Down Arrow (Lock) keys.
3. Press and release the Up Arrow (Macro) key to increase the volume
or the Down Arrow (Lock) key to decrease the volume.
The pressed key flashes and then stays illuminated.
4. Repeat step three until the desired volume level is reached.
5. Select another destination to adjust.
Or press the Cancel key to return to Switch (default) mode.
