RF Safety
General
Your ModemModule is based on the GSM standard for cellular technology. The GSM standard is spread all over
the world. It covers Europe, Asia and some parts of America and Africa. This is the most used
telecommunication standard. Your modem is actually a low power radio transmitter and receiver. It sends out
and receives radio frequency energy. When you use your ModemModule integrated modem, the cellular system
that handles your calls controls both the radio frequency and the power level of your cellular modem.
Exposure to RF Energy
There has been some public concern about possible health effects of using GSM modems. Although research on
health effects from RF energy has focused on the current RF technology for many years, scientists have begun
research regarding newer radio technologies, such as GSM. After existing research had been reviewed, and
after compliance to all applicable safety standards had been tested, it has been concluded that the product was
fitted for use. If you are concerned about exposure to RF energy there are things you can do to minimize
exposure. Obviously, limiting the duration of your calls will reduce your exposure to RF energy. In addition, you
can reduce RF exposure by operating your cellular modem efficiently by following the below guidelines.
Efficient Modem Operation
For your modem to operate at the lowest power level, consistent with satisfactory call quality:
· If your modem has an extendible antenna, extend it fully. Some models allow you to place a call with
the antenna retracted. However your modem operates more efficiently with the antenna fully extended.
· Do not hold the antenna when the modem is « IN USE ». Holding the antenna affects call quality and
may cause the modem to operate at a higher power level than needed.
Antenna Care and Replacement
Do not use the modem with a damaged antenna. If a damaged antenna comes into contact with the skin, a minor
burn may result. Replace a damaged antenna immediately. Consult your manual to see if you may change the
antenna yourself. If so, use only a manufacturer-approved antenna. Otherwise, have your antenna repaired by a
qualified technician. Use only the supplied or approved antenna. Unauthorized antennas, modifications or
attachments could damage the modem and may contravene local RF emission regulations or invalidate type
approval.
