The Federal Communications Commission (FCC), with its action  

in General Docket 93-62, November 7, 1997, has adopted a  

safety standard for human exposure to Radio Frequency (RF) electromagnetic energy emitted by FCC regulated 

equipment. Topaz3 / Maxon subscribes to the same safety standard for the  

use of its products. Proper operation of this radio will result in  

user exposure far below the Occupational Safety and Health Act (OSHA) and Federal Communications Commission limits. 

 

Power listed is conducted. This device must not exceed a maximum transmitting duty factor of 50%. The antenna(s) used 

for this transmitter must be installed to provide a separation distance of at least 49cm (19 inches) from all persons, must not 

be co-located or operating in conjunction with any other antenna or transmitter, and must not exceed a gain of 5 dBd for 

SD-161 and 7 dBd for SD-164. Failure to observe these restrictions will result in exceeding the FCC RF exposure limits. 

The SD-160 Series of RF Link Modules from Topaz3 utilize the latest technology in their designs and manufacturing. SD-

160 models are Phase Lock Loop Synthesizer (PLL) / microprocessor controlled and offer two (2) watts of power with 16-

channel capability. Multiple functions including 1200 to 9600 baud rates, AC and/or DC audio coupling, GMSK, FFSK and 

FSK modulation are standard in these fully programmable RF Link Module units. Programmable sub-audio squelch system 

(CTCSS & DCS) and two-tone squelch system are added to the signal level detect squelch system (RSSI). GPS Data 

handling is provided to interface and control an internal GPS receiver.
