FCC RF Exposure Requirements:
CAUTION:
The antenna(s) used for this transmitter must not be co-located or operating in conjunction
with any other antenna or transmitter. This device is approved with emissions having a
source-based time-averaging duty factor not exceeding 50%.
Failure to observe these restrictions will result in exceeding the FCC RF exposure limits.
In any case, take the following points into consideration:
 Most electronic equipments are susceptible to electromagnetic interference if
they are not duly protected. If the RF Unit is placed near unprotected
electronic devices, they may malfunction.
 The RF Unit must not transmit without its antenna connected or without the
50Ω load in the TNC connector.
 When installing the antenna, follow the guidelines for exposure of the human
body to high and low frequency electromagnetic fields. Follow the supplier’s /
manufacturer’s instructions.
 Burns may be suffered if the antenna connector output of the power module
(RPA P25) is touched by bare skin when the RF Unit is transmitting with the
antenna disconnected.
 Take care when handling the RF Unit. It has sharp edges, which may cut if
handled incorrectly.
 Maintenance and repair of these repeaters must be carried out by qualified
personnel only.
 Connect the RF Unit chassis to the earth intake in the cabinet where it is to
be installed.
 Switch off the RF Unit before inserting/removing any of its modules
