What are typical steps for performing preventive maintenance on a field radio?

• A. Inspect casing and connectors, test battery and power, verify frequency and encryption status, check antenna and coax, update software if available
• B. Only recharge the battery
• C. Clean the exterior and end the maintenance
• D. Replace all hardware components annually

Answer: (A)

Preventive maintenance on a field radio means checking all the essential operating and safety aspects so the radio will perform when needed. Start with the physical health: inspect the casing and connectors for cracks, corrosion, moisture, or loose joints, since ingress can cause failure or intermittent operation. Then power readiness: test the battery and power system to confirm adequate capacity and reliable startup under load. Next, correct configuration: verify that the radio is set to the assigned frequencies and channel plan and that encryption status is correct for the mission, so you’re not stuck on an unintended channel or exposing unencrypted traffic. Then RF integrity: check the antenna and coax for wear, damage, moisture, loose mounts, and test or visually inspect the feedline to reduce reflections and ensure good range. Finally, software readiness: update the radio software if updates are available, which can fix bugs, improve performance, and address security vulnerabilities. These steps together cover hardware integrity, power, configuration, RF path, and software readiness, making it the most comprehensive approach to preventive maintenance. The other options only address one aspect or suggest impractical actions (recharging alone, cleaning only, or replacing everything yearly), which would leave the radio unprepared in the field.
