6.2 Safety recommendations (for information only)
IMPORTANT
FOR THE EFFICIENT AND SAFE OPERATION OF
YOUR GSM APPLICATION BASED ON MG260
PLEASE READ THIS INFORMATION CAREFULLY
6.2.1 RF safety
6.2.1.1 General
Your application using the MG260 module 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 GSM terminal is actually a low power radio transmitter and receiver. It sends
out and receives radio frequency energy. When you use your
GSM application, the cellular system which handles your calls controls both the
radio frequency and the power level of your cellular modem.
6.2.1.2 Exposure to RF energy
There has been some public concern about possible health effects of using GSM
terminals.
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 terminal efficiently by following the below guidelines.
6.2.1.3 Efficient terminal operation
For your GSM terminal to operate at the lowest power level, consistent with
satisfactory call quality:
• If your terminal has an extendible antenna, extend it fully. Some models
allow you to place a call with the antenna retracted. However your GSM
terminal operates more efficiently with the antenna fully extended.
• Do not hold the antenna when the terminal is « IN USE ». Holding the
antenna affects call quality and may cause the modem to operate at a
higher power level than needed.
