FCC RF exposure warning
To ensure optimal transceiver performance and to avoid exposure to excessive
electromagnetic fields, the antenna system must be installed according to the
instructions provided.
High voltages exist on the antenna during transmission and tuning. Do not touch
the antenna during these activities. RF bums may result.
Install the grounding system or counterpoise as directed to prevent RF bums from
any metal part of the transceiver.
Safe working distance is based on continuous exposure to CW type transmissions,
as set out in the ICNIRP Exposure Guidelines (1998) for occupational exposure.
Safe working distance can be reduced with normal voice communication.
For FCC compliance, when the PRC-2090 transceiver is used at a power
level of 100 watts PEP, the antenna(s) used with this transceiver should be located
at least 3 metres from the operator and should not be co-located or operating in
conjunction with any other antenna or transmitter.
For FCC compliance, when the PRC-2090 transceiver is used at a power
level of 30 watts PEP, the antenna(s) used with this transceiver should be located
at least 1.5 metres from the operator and should not be co-located or operating in
conjunction with any other antenna or transmitter.
