Ranges and Method of Transmission

It is not possible to exactly predict the distance over which the Pro Max system will perform.
Several factors may affect the distance and reliability of any radio transmission:

• Frequency used

• Transmission Power

• Terrain

• Antenna placement

• Building Structures

• Weather conditions

• On channel interference

• Atmospheric disturbances

• Antenna types

• Mode of operation (AM, FM, etc.)

Your Pro Max system has been designed to operate at distances up to one mile. Under ideal open
field conditions, it can readily operate up to 5 miles.

When attempting to use Pro Max over extended distances, it is important to ensure that the
receiving antenna is properly located. If possible, avoid Pro Max receiver antenna locations,
