SAMXT User Guide V1.5

1 Introduction

The SAMXT is a compact, light-weight, LTE based modem. It provides CATM1, 3GPP Release
13 compliant with the uplink speed of (up to) 375Kbps and downlink speed of (up to) 300Kbps in
Cat M1 Mode.

The SAMXT is designed for both mobile and fixed M2M applications. It has an RJ45 socket for
input voltage and the serial RS232 signals, one FME-male for main antenna connection, a SIM
holder and an LED indicator.

The SAMXT is controlled by a set of AT commands.

2 Safety Precautions

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

• In hospitals or places where medical equipment may be in use

• In an aircraft

• Refueling points

• Explosive areas

- Restricted use of the SAMXT modem:

• Near any chemical plant

• Near any fuel depot

• Areas with mobile phone warning signs

Respect national regulations on the use of cellular devices.

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

3 Radio Frequency Exposure - SAR

The SAMXT modem is a low-power transceiver, similar to a typical handheld 3G/LTE 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 SAMXT modem is approved to use in applications where the antenna is placed more

than 21cm from the body.

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