Note: For RB-SD1 units with serial number greater than RB031084, the SOURCE LED
is used to show the bank of the selected mode. For serial numbers before this, the
SOURCE LED is not used. Contact Sonifex Ltd if you want to upgrade your RB-SD1 unit
to the latest version to take advantage of a new mode.
To select the particular mode, release the RESTORE button when the corresponding LED
below is on. After the button is released the unit will start working after five seconds. You
only have to do this once as the mode is stored in non-volatile memory and you will only
need to repeat this procedure if you wish to select a different mode. Each time the unit is
powered on, the selected mode is visible by checking which LED is on:
