independent of others.
Select the required channels using various selection methods.

3) Operation in Scaler output mode:-

Press the scaler key to go in scaler model (LED ON). When scaler
LED is ON, VGA (output) goes in Scaler mode. Whichever key is
pressed last the output is seen in VGA i.e. C-Video is converted to
VGA output.
C-Video output still works independently, only VGA output is scaled.

Note: – To Blank All the O/P’s press Clear Key. To Blank VGA O/P only press
any key on VGA for more than one Sec. Similarly for C-Video.
