5.5 KEY LOCK/UNLOCK
5.5.1 Functions
To prevent tampering following installation, invoke "KEY LOCK" status to prevent use of "the main-body operation
panel" or "the remote control". (RS-232C commands are valid.)
If an attempt is made to use "the operation panel" or "the remote control", the screen displays "KEY LOCK" at the top
right.
The system is factory-set to "KEY UNLOCK" to enable use of "the operation panel" and "the remote control".
5.5.2 Setting method
KEY LOCK status can be set in two ways.
1) Operation panel of the main body (hidden button)
Press the KEY LOCK/UNLOCK button located in the opening between the STANDBY/ON button and INPUT button.
The button toggles between KEY LOCK and KEY UNLOCK settings.
2) RS-232C commands
Activate RS-232C adjustment mode and
send a <KLY> command to set for KEY LOCK status, or
send a <KLN> command to set for KEY UNLOCK.
