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.
