After making any connections to your unit, activate the AXA35 by pressing the Power button on the front of the unit.
Use either the Volume Up/Down buttons on the remote control, or the Volume control on the front of your unit system to change the volume level. The newly selected level will be indicated briefly on the front display.
The volume is displayed in minus dB where 0dB is the highest level.
A progressively larger negative number indicates the volume is being reduced.
