roll long cables.
• Change power supplies.
• Power the monitor/module huousing through an isolation

Notes:
• At 80 MHz and 800 MHz, the separation distance for the higher frequency range
applies.
• These guidelines may not apply in all situations. Electromagnetic propagation is
affected by absorption and reflection from structures, objects, and people.
