What should you do for safety, before removing the shielding on a UHF power amplifier?
- AMake sure all RF screens are in place at the amplifier output connector
- BMake sure the amplifier cannot accidentally be turned on
- CMake sure that RF leakage filters are connected
- DMake sure the amplifier output connector is grounded
Correct answer: B — Make sure the amplifier cannot accidentally be turned on. From the official ISED question bank, verified word for word.
Why
Removing the shielding exposes you to dangerous high voltages inside the amplifier, so the most critical step is to ensure the amplifier cannot accidentally be turned on. The full explanation — and one for every question — is in Pro.
