red ‘Conrm’ button will appear beneath the PROC mode button; touch it

System: The System submenu allows you to set volume presets for each 
of the two outputs of the SP20, check the software version, and set the unit 
back to factory defaults. 
Reset Defaults: To reset the SP20 to the original factory settings, touch 
the  ‘Factory  Defaults’  button,  followed  by  conrm.  This  will  erase  any 
customized data you have stored.
Volume Presets: The speaker (main) and headphone output volumes can 
be customized so that when switching between the outputs, inadvertent 
equipment or hearing damage may be avoided. From the System submenu, 
select Volume Presets. Use the up and down arrow buttons to change 
the preset volume for each output. Note that each time you switch from 
one output to the other, the volume preset takes effect and will adjust the 
volume according to the customized settings.
SP20 About: Touching the ‘About’ button displays a screen with the current 
software version of the SP20. This information can be useful in the event 
the SP20 needs troubleshooting.
Display: The Display submenu allows you to adjust the screen timeout and 
the brightness of the green bar on the timeout screen. To adjust brightness, 
move your  nger along  the slider  between the  two icons.  The green line 
will change in brightness relative to the position of the arrows on the slider. 
To adjust the screen timeout, moving the slider will change the timeout 
from ‘Always On’ to up to 12 seconds. When engaged, the timeout feature 
will dim the screen when no input (from touching the screen or using the 
remote) is sensed for the assigned time period.
System Auto Shutdown: As an energy-saving measure, the SP20 offers 
an auto-shutdown feature. When engaged, the SP20 will automatically shut 
off after the specied amount of time from turn-on. The default setting is 
‘always on’; moving the slider towards the right, ‘always on’ will no longer 
appear, and on the right side of the slider, the number will correspond to the 
auto shut off time (in hours).
