1. Foreword

1.1. Document Description

This document describes the electrical characteristics, RF performance, dimensions and

application environment, etc. of the FM101-NA-20 wireless module. With the assistance of

this document and other related documents, application developers can quickly

understand the hardware functions of the FM101-NA-20 module and develop product

hardware.

1.2. Safety Instructions

By following the safety guidelines below, you can ensure your personal safety and help

protect the product and work environment from potential damage. Product

manufacturers need to communicate the following safety instructions to end users.

Fibocom Wireless does not assume any responsibility for the consequences caused by

users' misuse because they do not comply with these safety rules.

Road safety first! When you are driving, do not use any handheld mobile

device even if it has a hand-free feature. Stop the car before making a

call.

Please turn off the mobile device before boarding. The wireless feature

of the mobile device is not allowed on the aircraft to prevent

interference with the aircraft communication system. Ignoring this note

may result in flight safety issue or even violate the law.

When in a hospital or health care facility, please be aware of restrictions

on the use of mobile devices. Radio frequency interference may cause

medical equipment to malfunction, so it may be necessary to turn off

the mobile device.

1. Foreword

Fibocom Confidential

The mobile device does not guarantee that an effective connection can

be made under any circumstances, for example, when there is no

prepayment for the mobile device or (U)SIM is invalid. When you

encounter the above situation in an emergency, please remember to

use emergency calls, and ensure that your device is turned on and in an

area with strong signal.

Your mobile device receives and transmits RF signals when it is powered

on. Your mobile device will receive and transmit RF signals when it is

turned on. RF interference occurs when it is near a TV, radio, computer,

or other electronic device.

Keep mobile device away from flammable gases. Turn off the mobile

device when you are near to gas stations, oil depots, chemical plants or

explosive workplaces. There are potential safety hazards when

operating electronic equipment in any potentially explosive area.
