Digital Keyset Programming

The DCS-408/DCS-408i system can automatically program keys for a variety of Samsung
digital keysets. Keysets which can be connected to these systems include:
DCS (Euro) keysets (24-, 12- and 6-button versions)
iDCS series keysets (28-, 18- and 8-button versions)
Keys can be programmed with functions such as frequently dialled trunk numbers and station
(extension) numbers, speed dial numbers, call pickup, paging and many more.
Refer to the Samsung Combined Programming Manual for more information on program-
ming your system and keysets, and to the appropriate Samsung Keyset User Guide for op-
erating your keysets.

Replacing System ROMs

You need to replace system ROM chips when upgrading the system program or fixing bugs
in the program. Before replacing the system ROMs, read this section carefully. If there are
any problems, or if you are unsure of anything, contact your dealer or the Samsung Technical
Support department for advice.
Replace the ROMs as follows.
1. Switch off the mains power and remove the power cable.
2. Remove the side cover of the system unit as described earlier. If you want to reprogram
the new system (using MMCs) when you've finished installing the new ROMs, set the
MEM BACK-UP switch to OFF to initialise the previous system data.
3. Remove the front cover of the system unit as described earlier
4. If an external battery is installed, remove it.
5. Locate the ROMs to be replaced. There are four ROMs on the baseboard, as shown in the
diagram.
NOTE: Older versions of the 408 may have only two ROMS: EVEN1 and ODD1.
