• Before installing options, please do the following:
If there is a fax unit in the machine, print out all messages stored in the memory, the lists of user-
programmed items, and the system parameter list.
If there are printer jobs in the machine, print out all jobs in the printer buffer.
Turn off the main switch and disconnect the power cord, the telephone line, and the network cable.
• Always touch a grounded surface to discharge static electricity from your hands before you handle SD
