3.2 G4CCU STATUS CODES
The display of G4CCU status codes is affected by the Real Time Display On/off
setting (G4 Parameter Switch E, bit 0).
• If Real Time Display is off (the bit is 0; this is the default setting), there is no
indication on the operation panel.
• If Real Time Display is on (the bit is 1), the codes are fully displayed on the
operation panel.
