SAFETY- RF EXPOSURE COMPLIANCE This device has been designed using a low power transmitter. It complies with the Federal Communications Commission (FCC) RF exposure limits for General Population/Uncontrolled exposure environment. In addition, it complies with the following Standards and Guidelines: • • • • • • FCC 96-326 (1996), Guidelines for Evaluating the Environmental Effects of Radio-Frequency Radiation.
1. Purpose and application of the Radio Modules 70TXRX-M1 The 70TXRX-M1 Radio Modules, comprising of the 70TX-M1 Transmitter 70RX-M1 and the Receiver are FM-narrow bandwith type radio modules. They are single channel, crystal controlled devices on an assigned frequency in the range from 420 – 510 MHz, in 12.5 or 25 KHz spacing. The modules are supplied by HM-Funktechnik GmbH (HM-Radio USA) as an OEM product and are to be installed in customer designed peripherals, such as 2.
