Older remote controls are sometimes dangerous because of which issue?

• A. Range too short
• B. Weather interference
• C. Conflicting low operating frequencies
• D. Battery issues

Answer: (C)

The main issue here is how radio control frequencies can cause dangerous interference. Older remote controls often operate on lower, crowded radio bands and lack modern protections like frequency hopping or rolling codes. In a busy crane yard with multiple machines and other wireless devices, signals from one remote can collide with or be picked up by another receiver. That means a command intended for one crane might be received by a different system, or a signal might be misinterpreted, leading to unpredictable crane movement or failure to respond to a stop command. This kind of frequency conflict is what makes older remotes potentially dangerous. Range too short can limit control, but it doesn’t inherently create cross-device interference. Weather interference isn’t typically a factor for indoor RF controls, and battery issues cause intermittent operation rather than systemic frequency conflicts.
