As with all RF devices, certain environmental conditions must be present to
optimize RF communications. Be aware of the factors that affect the radio
transmission between the ORION and the EMTR-3 when performing the field
survey, such as:
• Metal objects
• Thick walls or foliage
• Local radio interference
• Position of the ORION and/or EMTR-3
• Thick walls or foliage
• Local radio interference
• Position of the ORION and/or EMTR-3
