Front Panel Interface35PLM Series Operation Manual rev 1.1.97.8.3 Rotary EncoderThe rotary encoder is used to adjust parameters in conjunction with the selection made via the dynamicfunction buttons and LCD menus. The ring around the rotary encoder illuminates when a selected parameteris available for adjustment.Turn the encoder clockwise to increase the selected parameter, or counter-clockwise to decrease the value.Parameters with only two states (e.g. ON, OFF) are toggled by turning clockwise or counter-clockwise.Some parameters enable simultaneous adjustment of a combination of input and output channels.To select which channels are adjusted:1. Press the associated soft button/s to select the parameter/s for editing.A selected parameter is indicated by inverse text and background color.2. Use the rotary encoder to change the value.It is possible to select multiple parameters for simultaneous editing even if the values are different on eachchannel. Turning the rotary encoder will adjust each parameter by the same increment. When in MeterMode, the rotary encoder allows the user to change between the available meter views.Some menus permit parameters to be adjustedacross multiple channels simultaneously by default.7.8.4 Dynamic Function ButtonsThe buttons surrounding the display are unlabeled because their functions change according to the currentlyselected menu or display.In Meter Mode with MUTE ENABLE activated, these dynamic function buttons are used to mute or unmutethe Module Inputs and power output channels.In Menu Mode these buttons are used to navigate the menu structure. During menu navigation, the colorof the embedded LEDs continue to indicate the mute status, or clips, faults and warnings relevant to theassociated input or output channel on the PLM.Each button contains a tricolor LED which conveysfault and warning indications in addition to the mutestatus. The LED color does not necessarilycorrespond to the currently selected function.
