General Operation
NOTE: While the Remote Control (Fig 3) and the front panel of each tuner (Fig 1) share some common
function controls, a few functions are ONLY available using the Remote Control, namely: DIRECT, RDS,
MUTE, ASM, MO/ST, TUNER/DAB. (ASM doubles as INFO button when the DAB+/FM tuner is active.)

DAB button. When pressed, the word MUTE will flash on the screen.
- The LCD displays of each tuner will show the current frequency or Station ID for which each receiver is
tuned, for whichever band or mode has been selected.

to toggle between which section (Left or Right) that the remote will control. A blue light on the front panel

DAB section operation.
