Checking the Position of the Slide Switch (SW1) on the Voice Guidance Board
The slide switch (SW1) on the Voice Guidance Board 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. If you inadvertently moved the slide, be sure to put it
back to its correct position. For the Boad, the frequency must be set to 33 MHz.
