Before operating the printer, set these function switches
following the procedure described below.

Follow the procedure described below, in operating the function switches.
I. Confinn that power is turned off while the ROM unit is connected to MZ-80P4.
2. Next, set the function switches representing the desired operations.
3. Turn on power for MZ-80P4.
(Caution) Do not operate the function switches while power is turned on. Otherwise, wrong operation
or trouble may be caused.
