Checking the slide switch SW1 on the voice
guidance board
The slide switch (SW1) on the Voice Guidance
Board-A1 is provided as a means of switching
frequencies (33 MHz/66 MHz) to suit the transfer
speed of the PCI bus. It is important for the switch
setting to suit the transfer speed so that the voice
will be free of interruption.
For the machine, 66MHz is the correct position of
the switch.
