Audio signals
The CR 75.0 gives status information via beeps. The length of the beep
indicates the response of the system to a key command.
• A short beep means that CR 75.0 has accepted the key command and is
starting the operation.
• A long beep means that you have pressed a non-active key or that the
CR 75.0 has rejected the key command.
• An interval beep accompanies an error, locked or warning message. Refer to
Chapter 4, ‘Preventive maintenance and troubleshooting’.
