What is the second step in troubleshooting a wireless transmitter?

• A. Test or replace the battery
• B. Relocate the transmitter to test it
• C. Check for interference
• D. Replace the transmitter

Answer: (A)

Power and battery status are the first things to confirm when a wireless transmitter isn’t working. The second step is to test or replace the battery because a weak or dead battery is the most common reason the device won’t transmit. A reliable power source is required for any further troubleshooting, so verifying or upgrading the battery quickly rules out a simple, fixable cause and prevents chasing issues like interference or placement problems. If the battery checks out, you’d then proceed to other checks such as interference or repositioning; replacing the transmitter is typically reserved for situations where power and all other diagnostics fail.
