In 1991, the Institute of Electrical and Electronics Engineers (IEEE), and in 1992, the American
National Standards Institute (ANSI), updated the 1982 ANSI Standard for safety levels with respect
to human exposure to RF energy. Over 121 scientists, engineers, and physicians from universities,
government health agencies and industry, after reviewing the available body of research, developed
this updated standard. In March 1993, the U.S. Federal Communications Commission (FCC)
proposed the adoption of this updated standard. The design of Wireless Data Relay complies with
this update.
Electronic Devices
Most modern electronic equipment is shielded from RF energy, however, RF
Energy from Wireless Data Relay may effect inadequately shielded electronic equipment.
Check with the manufacturer or it's representative to determine if the
Following equipment or systems are adequately shielded from external RF
Energy:
Motor Vehicle electronic and entertainment systems (standard and any add-on equipment.
Medical Equipment, hospital or personal (such as pacemakers, hearing aids, etc.).
Turn OFF Wireless Data Relay in health care facilities when any regulation posted in the areas
instructs you to do so. Hospitals or health care facilities may be using equipment that could be
sensitive to external RF energy.
Getting Started
Installation
Warning to minimize RF exposure the Remtrol MCW4 must be
mounted at least 20 cm from the nearest person.
Your MCW4 can be mounted using a variety of methods. You must consider the operating
environment when choosing a mounting option. For example, extreme temperature, heavy
vibration, or high electromagnetic interference areas may require a special mounting solution. The
MCW4 has a threaded hole in diagonal corners which may be used to bolt the MCW4 to the side of
the equipment being monitored, an equipment backboard or pole. The two holes are diagonally
apart on a rectangle 2.351in by 4.056in with each hole threaded for 1/4" bolts.
It should be mounted so that a separation distance of at least 20cm (8in) is maintained between the
body of the user and the MCW4.
The MCW4 can be mounted indoors in most urban areas. When used inside a building,
performance is improved if the antenna is located near a window, with few obstacles (wall,
furniture, equipment, etc.) between the antenna and the window. The antenna must be oriented
vertically for best performance.
