24: Removal of the annoying BEEP from the FM92E:
One of the first things that will strike you when you operate a Philips FM92E is the annoying beep when you change
channels.
Remove the covers so the bottom (solder) side of the Synthesizer board can be seen. This is the board under the plastic
sheet.
Position the unit with one side towards you such that the front panel is on the left and the rear panel on the right.
Locate the dual 11 pin solder rows on the left corner nearest yourself, this is labelled SK403.
Looking at the row which is further from the front panel, locate the solder point which is in the middle (6th pin from either
end). ie resistor R254.It also can be found on the receiver board, the smaller of the two hinged boards. With the board in a
vertical position (the only way to see the components) the resistor is located in the bottom right corner. It is the closest
resistor to SK203, a ribbon cable termination device. The resistor is mounted vertically and has a value of 1.5 M ohms. It is
also surrounded by capacitors. Second tip about locating this resistor is that it is dead in line with leg number 8 of IC202.
The cut, will not kill the beep completely, but it will certainly make it quieter than it was.
Cut the track joining to this pin with a sharp blade.
No more BEEP!
