7.3.4.5 Security Key-switch Configuration
Security key-switches can be configured to protect the operation of any microphone button.
When a button is protected, then the security key must be turned on for the button function to be allowed.
This security function is intended to safeguard emergency DVA triggers from inadvertent operation, but it
may also be used to protect buttons programmed for other purposes.
