User Manual for the Radio Module 70TX-D SAFETY- RF EXPOSURE COMPLIANCE This device has been designed to use as 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. • FCC OET Bulletin 65 Edition 01-01 (2001) Supplement C, Evaluating Compliance with FCC Guidelines for Human Exposure to Radio Frequency Electromagnetic Fields. • ANSI/IEEE C95.1-1992, IEEE Standard for Safety Levels with Respect to Human Exposure to Radio Frequency Electromagnetic Fields, 3 kHz to 300 GHz. • ANSI/IEEE C95.3-1992, IEEE Recommended Practice for the Measurement of Potentially Hazardous Electromagnetic Fields - RF and Microwave. • Use ONLY the supplied antenna and accessories. Unauthorized accessories may violate the FCC rules and regulations. • The module must be installed or integrated by providing a minimum separation distance of 20 cm between the antenna and the human body at all time. Label Requirement: • A label must be affixed to the outside of the end product into which the authorized module/product is incorporated, with a statement similar to the following: “This device contains TX with FCC ID: PUX70TX-D” 1. Purpose and application of the radio module 70TX-D The 70TX-D radio transmitter is a FM-narrow bandwith type radio module. It`s a single channel, crystal controlled device with 500mW output power on an assigned frequency in the range from 460 – 470 MHz, in 12.5 or 25 KHz spacing. The modules are supplied by HM-Funktechnik GmbH as an OEM product and are to be installed in customer designed peripherals, such as • radio remote control devices for machinery in industrial sites • burglar alarm system, data in general and voice, only in alarm conditions • data transmission in telemetry systems • data transmission in wireless hand held terminal systems • wireless data transmission in general
