Preventive maintenance on communication equipment involves keeping it?

Preventive maintenance on communication equipment is essential for ensuring that the equipment functions effectively and reliably. Keeping communication devices clean and dust-free prevents obstructions that can interfere with their performance. Dust and debris can accumulate on sensitive components and connections, leading to malfunctions or degradation of signals. Additionally, a clean environment helps maintain optimal thermal conditions, reducing the risk of overheating that can compromise the reliability of communication devices. Regular cleaning and maintenance routines ensure that equipment remains in good working order, which is crucial, especially in combat situations where clear communication can be vital to mission success.
