The Stand Alone modem, SAM, is designed to be a compact modem, easy to use for both mobile
and fixed machine to machine applications. It has an RJ45 socket for serial data and input power,
an FME male antenna connector, a SIM holder and an LED indicator.

The SAM is a Quad-band 850/900/1800/1900MHz GSM/GPRS modem, capable of Circuit
Switched Data, Packet Switched data, SMS and Fax.

The RJ45 socket includes an RS232 serial port and input voltage signals. The LED is located
next to the SIM holder, which allows users to monitor the status of the modem in operation.

The SAM is controlled using a set of standard AT commands.

2. Safety Precautions

The following safety precautions must be observed whenever the SAM modem is in operation or
in service. Failure to comply with these precautions violates the safety standards of the design,
manufacture and intended use of the product

- Switch off the SAM modem :
In hospitals or places where medical equipments may be in use

In an aircraft
Refueling points
Explosive areas

- Restricted use of the SAM modem
Near any chemical plant

Near any Fuel depot
Areas with mobile phone warning sign

Respect national regulations on the use of cellular devices. Road safety always comes first
The SAM modem receives and transmit radio frequency energy while switched on, therefore

interference can occur if the SAM is near TVs, radios, PCs or any inadequately shielded
equipments.

3. Radio frequency exposure - SAR

The SAM2W modem is a low-power transceiver, similar to a typical handheld GSM/GPRS mobile
phone. When it is turned on, it will emit low-level radio frequency energy.

There are different guidelines and standards around the world that govern the permitted levels of
radio frequency exposure for general population. The levels include a safety margin to a human
body.

The Specific Absorption rate (SAR) is a measure of the rate at which radio frequency energy is
absorbed by the body when exposed to radio frequency electromagnetic field. The SAR value is
determined at the highest certified power level in the laboratory conditions, but the actual SAR
level of the transceiver while operating can be well below this value. This is because the
transceiver is designed to use minimum power to connect to the network.

The SAM2W modem is approved to use in applications where the antenna is placed more than
20cm from the body. Refer to the SAR calculations in the Appendix A.

For other applications, the integrator is responsible for the local SAR requirements.

4. WEEE directive 2002/96/EC, disposal of old electronic equipment
