Depressing the RTU Inhibit switchlight enables what function?

• A. Enables alternate cross side tuning of the radios of the failed RTU
• B. Enables automatic RTU self-test
• C. Locks the RTU in place
• D. Powers down the RTU

Answer: (A)

Depressing the RTU Inhibit switchlight enables alternate cross side tuning of the radios of the failed RTU. When you inhibit the failed RTU, the remaining RTU can take over tuning those radios through a cross-side path, allowing you to select and set frequencies for both radios even with the failed unit. It doesn’t trigger self-test, lock the RTU, or power it down; it simply enables the alternate tuning path.
