Keep the device far from radio transmitting stations, radar stations, and high-frequency devices. Use electromagnetic shielding when necessary, for example, use shielded interface cables. Route interface cables only indoors to prevent signal ports from getting damaged by overvoltage or overcurrent caused by lightning strikes.
