B230/B237 5-6  SM 
A sharp (#) to the right hand side of the mode number column means that the main switch 
must be turned off and on to effect the setting change. 
An asterisk (*) to the right hand side of the mode number column means that this mode is 
stored in the NVRAM. If you do a RAM clear, this SP mode will be reset to the default value. 
“ENG” and “CTL” show which NVRAM contains the data. 
ƒ  ENG: NVRAM on the BICU board 
ƒ  CTL: NVRAM on the controller board 
The settings of each SP mode are explained in the right-hand column of the SP table in the 
following way. 
[Adjustable range / Default setting / Step ] Alphanumeric 
 
ƒ  If “Alphanumeric” is written to the right of the bracket as shown above, the setting 
of the SP mode shows on the screen using alphanumeric characters instead of 
only numbers. However, the settings in the bracket in the SP mode table are 
explained by using only the numbers. 
SSP: This denotes a “Special Service Program” mode setting.
