1 Introduction

This document gives a general introduction of key features, functions, interface description,

electrical characteristics and RF characteristics and layout of the M2 Mini PCIe-C module (“M2”).

1.1 Safety Information

The following safety precautions shall be observed to ensure your safety and protect your device

and working environment from potential damage.

Road safety comes first! Using a mobile device while driving is prohibited even
it has speakerphone. Please pull over your car in a safe place first then make
or receive a call.

Switch your phone off before take-off. Electromagnetic waves emitted by your
phone may affect the electronic navigation equipment in the aircraft. The
ignorance of this tip may affect fight safety or even break the law.

Be aware if there are any restrictions on mobile device use during a hospital or
healthcare facility. All medical equipment may be susceptible to radio frequency
interference, which could affect performance, so you shall switch off your
mobile device.

It cannot guarantee that mobile device can access Internet under any
circumstances. For example, when you run out of credits or insert invalid SIM
card. For any emergency situations, remember to make the emergency call and
make sure your device is powered on and you are in an area with known-good

Your mobile device would send and receive radio frequency signal when
switched on. The interference occurs when you place the device near
television, radio, computer and other electronic devices.

Do not place your mobile device near inflammable gas. Always switch off your
mobile device near gas station, oil depot, chemical plant or explosion areas.
Operating the mobile device in potential explosion areas has risk.
