System Options

The DCS-408/DCS-408i digital keyphone system includes several kinds of optional hardware
for memory backup selection, music source selection, etc.
Memory Backup Selection
The system is provided with a memory backup circuit (with a MEM BACK-UP switch) em-
ploying 256K memory and a super-capacitor in case of power failure. The MEM BACK-UP
switch is located on the upper right-hand side of the unit and is set to OFF by default.
When you have finished programming your system (using MMCs as described in the Sam-
sung Combined Programming Manual), turn the MEM BACK-UP switch to ON. If the switch
is not turned ON, all programmed data will be deleted if a power failure occurs.
