RF Exposure Warning
WARNING: This device generates and radiates RF electromagnetic energy and must
be installed and operated according to the instructions contained in this manual.
Failure to do so may result in product malfunction and/or exposure to potentially
harmful levels of radio frequency radiation.
WARNING: Never operate this device unless it is properly connected to a VHF
antenna. To maximize performance and minimize human exposure to RF energy,
always mount the antenna at least 3m from the device.
The system has a Maximum Permissible Exposure (MPE) radius of 60cm from the
antenna. This has been determined assuming the maximum power of the transmitter
and using a standard half-wave monopole VHF antenna with a maximum gain of 3dBi
and termination impedance of 50 ohms.
When installing the antenna and operating the equipment consider the following:
 The antenna should be mounted at a minimum vertical distance of 5m
above the deck in order to meet international safety directives on
Maximum Permissible Exposure (MPE). Failure to adhere to these limits
could expose persons within the 60cm radius to RF radiation in excess of
the recommended MPE limits.
 Higher gain VHF antennas will require a larger MPE radius.
 Do not operate the unit when anyone is within the MPE radius of the
antenna.
 The antenna should not be co-located or operated in conjunction with any
other transmitting antenna.
