1. Introduction

The SAM3G is a compact, light-weight, UMTS based modem. It provides GSM, GPRS, EDGE
and WCDMA connectivity.

- GSM, GPRS, EDGE : 850MHz, 900MHz, 1800MHz, 1900MHz

- UMTS, WCDMA/HSDPA : 850MHz, 1900MHz, 2100MHz

The SAM3G is designed for both mobile and fixed M2M applications. It has an RJ45 socket for
both input voltage and serial RS232 signals, a MiniB USB connector, a SMB-Jack for antenna
connection, a SIM holder and an LED indicator.

The SAM3G is capable of sending/receiving SMS, Circuit switched data and Packet-switched
data.

2. Safety Precautions

The following safety precautions must be observed whenever the SAM3G 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 SAM3G modem :

 In hospitals or places where medical equipments may be in use.
 In an aircraft
 Refueling points
 Explosive areas

- Restricted use of

the SAM3G

modem

 Near any chemical plant
 Near any Fuel depot
 Areas with mobile phone warning signs

Respect national regulation

s on the use of cellular devices. Road safety always comes first

The SAM3G modem receives and transmit radio frequency energy while switched on,
therefore interference can occur if the SAM3G is near TVs, radios, PCs or any inadequately
shielded equipments.

3. Radio frequency exposure - SAR

The SAM3G modem is a low-power transceiver, similar to a typical handheld GSM/GPRS/UMTS
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 SAM3G modem is approved to use in applications where the antenna is placed more than

20cm from th

tions, the integrator is responsible for the local SAR requirements.
