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.
• 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 ID: XXXXXXXXXXX
1. Purpose and application of the Radio Modules 70TXRX-M1
The 70TXRX-M1 Radio Modules, comprising of the
Transmitter 70TX-M1 and the Receiver 70RX-M1
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
- 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
