CONCENTRA LED Volume Level Display

The LED Display on JRDG equipment operates in either of two modes. Constant display, or 5 second display. In the 5 sec. mode, the screen will be blank until a change in status (input select, volume level, etc.) is sent to the unit. The display will come on for 5 sec., then go blank again.

To change the Concentra display mode, remove the top cover and change the position of switch SW1 #2, the upper slide switch. It is located on the power supply regulator circuit board. It is necessary to reset the microprocessor after this change. Simply hold the mute button for 5 seconds and release.
