Option Settings
Options are used to control the presence/absence of certain features and hardware.
There are two ways to change the option settings (see also figure 8-6):
Changing a single option
An option can be selected with the “MENU UP/DOWN” keys and its setting can be
changed with the “MENU LEFT/RIGHT” keys.
Changes in the option settings are saved by leaving the OPTION submenu. Some
changes will only take effect after the set has been switched off by breaking the AC
mains supply (cold start).
Changing multiple options by changing option byte values
Changing the option bytes directly makes it possible to set all options very fast. An
option byte (OB1..8) can be selected with the “MENU UP/DOWN” keys and its setting
can be changed with the “MENU LEFT/RIGHT” keys. An option byte represents a
number of different options. All options of the N8 are controlled via 8 option bytes.
Select the option byte (OB1..OB8) and key in the new value.
