1.4 Safety Information
This repeater emits radio frequency (RF) energy when transmitting. Make sure to observe
all RF energy exposure standards when installing, testing, repairing, and operating this radio equipment.
The FCC has adopted a safety standard for human exposure to RF energy. Proper operation of this
repeater under normal conditions results in user exposure to RF energy below the Occupational Safety
and Health Act and Federal Communication Commission limits.
- Do not allow the antenna to touch or come in very close proximity with the eyes, face, or any
exposed body parts while the repeater is transmitting.
- To comply with FCC RF exposure limits, do not operate the transmitter of a stationary radio (base
station or marine radio) when a person is within fourteen (14) feet [four (4) meters] of the antenna.
- Do not operate the repeater in explosive or flammable atmospheres. The transmitted repeater energy
could trigger blasting caps or cause an explosion.
- Do not operate the repeater without the proper antenna installed.
- Do not allow children to operate transmitter equipped repeater equipment.
