The following symbols are used in the SP mode tables.

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

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.

An asterisk (*) to the right hand side of the mode number column means that this mode is
stored in the NVRAM and EEPROM. 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.

ENG: EEPROM on the BiCU

CTL: NVRAM on the controller board

A sharp (#) to the right hand side of the mode number column means that the main power
must be turned OFF and ON to effect the setting change.

Data may be adjusted from the default setting at the factory. Refer to the factory setting
sheets enclosed.
