5. SCHEMATICS OF IR BOARD & KEY BOARD
Note:
The dividing resistor which is corresponding to the power key must be the least, otherwise, the key
which the least one is corresponding to will work as power key, too.
Recommended order:
K0=INPUT, K1= CH+, K2=CH-, K3= VOL+, K4= VOL-, K5=MENU, K6=POWER, K7=NULL
