The manual, which is specific to this model, shows the green remote as a method of changing settings but it mentions nothing about remote access from a master tv etc or whether the smart card system overrides access by the master remote.

The television is shipped in Commercial mode; however, at times it may be necessary to operate the set in Consumer mode. To switch between Commercial Mode and Consumer Mode the following sequence should be followed:
• With the RC2573GR Master setup remote enter 024995 and press the menu key.
• Use the Right cursor button to switch the Mode of the set between Consumer and
Commercial.
• With the proper mode selected, cursor down and use the Right cursor button to store
the selected mode.
•After the mode is stored, the television will power itself off. At this point disconnect
AC and perform a cold start on the television.
• The set should now be in the selected mode.

For the purpose of explanation, a guest remote, for the L04 series, similar to the illustration, is used. Remote control RC2573GR is a special and optional remote control specifically for configuring Institutional TV / Business Display Solutions features and SmartCard settings, and is purchased separately. Refer to the documentation for the RC2573GR for detailed information.
When you press RECALL on the RC2573GR setup remote control, when it is in setup mode, information similar to the following will appear on the TV screen. This information describes the TV chassis firmware version, diagnostic codes, setup information, and other service and technical data regarding the television configuration.
Line #10 indicates whether the TV is in CONSUMER or COMMERCIAL mode,
and whether it is on-line with a SmartPort DCM (such as a CLON99BK SmartLoader).
