The following statement will be added to the user/installation manual. CAUTION: Before performing any maintenance on the antennas or other radio frequency components of this transmitter you are instructed to turn the RF transmitter off. In performing any system maintenance while the RF transmitter is in operation you must maintain a separation distance of 32 cm or greater from any point on the antenna to insure compliance with the FCC RF exposure limits.
