7.3 Clearing Non-Volatile RAM
Caution:
Always perform the operation described here when using a new board for the first time. Note that this
operation deletes all previously set settings.
A NOVRAM clear is executed automatically after you write firmware to a new board. To execute a sepa-
rate NOVRAM (that is, not as part of this operation), follow the procedure given below.
Check that the operation unit (J14) and power supply (J10) are connected to the main board. Set the DIP
switch as shown below and switch on power.
