Lock or unlock the transmitter
If the transmitter has a display, a mechanical switch on the display can be used to lock or
unlock the transmitter. When locked, no configuration changes can be made using any
configuration tool.
Configuration and Use Manual
Security and write protection
Work with configuration files
When locked, the mechanical lock switch on the front of the display prevents any
configuration changes to the transmitter from any local or remote configuration
tool. A transmitter without a display does not have a lock switch.
If the Universal Service Port (USP) is disabled, the port cannot be used by any service
tool to communicate with or make changes to the transmitter.
When enabled, the software setting Write Protection prevents any configuration
changes. The setting can only be enabled if the transmitter does not have a display.
When enabled, the display Configuration Security prevents any configuration
changes being made from the display unless the display password is entered.
