Operation and Instruction Manualfor the Radio Module 70TX-S - PUX - 70TX-S
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 Transmitter module FCC ID: PUX-70TX-S.
1. Purpose and application of the Radio Module 70TX-S:The 70TX-S radio module is a FM-narrow bandwith type radio module. The transmitterallows the use of up to 256 channels within a bandwith of about 5MHz in the range from421 to 510 MHz. The spacing is 25KHz.The module is supplied by HM-Funktechnik GmbH (HM-Radio USA) as an OEMproduct and is 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- digitalvoice resp. synthesized voice for FRS

D0 to D7 changes the frequency of the transmitter. If the pins D0 to D7 are all open thetransmitter works with the lowest programmed frequency. The frequency adjustment is digitallycoded. Grounding of D0 rises the frequency about the channel spacing 25KHz. D1rises about double D0, D2 rises about double D1 and so on. So D7 rises the frequency about1600 times of D0 (27), that means 3.2MHz with 25KHz spacing.You can only use the preprogrammed frequencies. No other frequency is possible. Thestandard version uses 68 channels in the frequency range from 433.0625 to 434.775MHzwith a 25KHz spacing. If you programm a channel higher than 137 the frequency will staythe same than on 137.
