Failure to observe these guidelines mayexpose persons to RF radiation absorption exceeding the maximum permissible exposure (MPE).Garmin declares an MPE radius of 59 in. (1.5 m) for this system, which was determined using 25 watts output to an omni-directional 9 dBi gainantenna. The antenna should be installed such that a distance of 59 in. (1.5 m) is maintained between the antenna and all persons.WARNING: Radio operators with cardiac pacemakers, life-support machines, or electrical medical equipment should not be exposed to excessiveradio-frequency fields.WARNING: Operate the device in accordance with the instructions supplied.CAutIoN: Wear safety goggles and a dust mask when drilling, cutting, or sanding.NotICe: The device complies with internationally recognized standards covering human exposure to electromagnetic fields from radio devices.NotICe: Check with local authorities for any antenna or operational restrictions that may apply.NotICe: To prevent possible damage to your radio, the antenna must be connected to the radio before transmitting. This ensures that the power outputto the antenna port dissipates properly when transmitting.Needed ToolsDrill and drill bits#2 Phillips screwdriver3 1/2 in.
