4.3 Safety recommendations (for information only)
IMPORTANT
FOR THE EFFICIENT AND SAFE OPERATION OF
YOUR GSM APPLICATION BASED ON WISMO Quik Q24x6 Series
PLEASE READ THIS INFORMATION CAREFULLY
4.3.1 RF safety
4.3.1.1 General
Your GSM terminal

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.
4.3.1.2 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.
4.3.1.3 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.
4.3.1.4 Modular Transmitter
Modular transmitter. This device is to be used only for mobile and fixed applications.
The antenna(s) used for this transmitter must be installed to provide a separation distance of
at least 20 cm from all persons and must not be co-located or operating in conjunction with
any other antenna or transmitter. The antenna(s) used for this transmitter must not exceed
