Battery
An external battery input connection is provided through the Utility interface to support a battery backup for
the CMOS RAM and the RTC (Real Time Clock).
Reset Switch
An external reset switch provides the reset signal through the Utility interface to a reset circuit, which drives
the Vortex CPU.
Speaker
The speaker signal provides sufficient signal strength to drive a 1W 8
interface at an audible level. The speaker signal is driven from an on board amplifier and the Vortex CPU.
