[Premium-Rx] RA1792 S1A switch help

[Paul]

Hi Guys,

Discovering new things about this RX as I read thru and memorize the manual,
and one thing it states is that S1A on the front panel, allows presetting
your favourite mode with BW, filter etc. I can't get mine to work. What is
the switch sequence, "swicth on....power up...program"  etc?

Is it the red/white switch on the front left, top of the cct board attached
to the front panel cct board? The rear cct board of the 2 stacked.

Thanks

Paul
