To access the UserOps menu:
Turn the Select knob until UserOps appears on the display.
Press and release the Select knob.
Set the UserOps parameters as desired.
To set parameters such as step size ( StpSize ), update mode ( Update ), minimum
attenuation ( AbsMin ), base attenuation ( BaseAtt ), and reference value ( Refrnce ); turn the
Select knob to the desired value and then press and release to save changes.
To exit any menu without saving parameter changes, press and release the ESC button
before the settings are saved.
About UserAtten Mode Parameters
In UserAtten Mode, the user may set parameters such as step size (StpSize), update mode
(Update), and minimum attenuation (AbsMin). The scale can be adjusted using the base
attenuation (BaseAtt) and reference value (Refrnce) parameters. Both base attenuation and
reference can be used simultaneously, producing an actual attenuation equal to (Refrnce +
BaseAtt - {dial setting}). See PA5 Manual Operation for more information.
BaseAtt - Base Attenuation
Adds a xed attenuation value, shifting the scale down and allowing attenuation to be
displayed relative to this base level (useful for calibrating signals played over varying
transducers). See Setting Base Attenuation, for more information.
StpSize - Step Size
Sets the increments in which attenuation is applied to the signal when using the Select knob.
Refrnce - Reference
Sets a reference value used to "ip" the scale of the display (useful for displaying actual signal
level on the front panel of the PA5). May be used only when the intensity of the input signal is
known. See Setting a Reference Value for more information.
