Real-Time Clock Menus and Displays
In addition to the DSP functions, the KDSP2 includes a real-time clock (RTC) function. The clock
provides time and date information, and includes a Lithium backup cell. The real-time clock chip monitors
the status of the Lithium backup cell. If the voltage is below limits, the time and calendar displays will be
filled with E
Ee
.
ee

ee
or
ee-ee-ee
This means the cell voltage is low.
When you first construct the KDSP2, or after replacing the cell,
this display will also be seen.
Simply follow the clock and calendar setting procedure to erase the E’s. If
the cell voltage is low, the cell needs to be replaced.
