Safety Information

The following safety precautions must be observed during all phases of operation, such as usage, service

or repair of any cellular or mobile terminal incorporating the module. Manufacturers of the cellular terminal

should distribute the following safety precautions to users and operating personnel, and incorporate them

into all product manuals. Otherwise, Quectel assumes no liability for customer failure to comply with these

precautions.

Full attention must be paid to driving at all times in order to reduce the risk of an

accident. Using a mobile terminal while driving (even with a handsfree kit) causes

distraction and can lead to an accident. Please comply with laws and regulations

restricting the use of wireless devices while driving.

Switch off the cellular terminal or mobile before boarding an aircraft. The operation

of wireless appliances in an aircraft is forbidden to prevent interference with

communication systems. If there is an Airplane Mode, it should be enabled prior to

boarding an aircraft. Please consult the airline staff for more restrictions on the use

of wireless devices on an aircraft.

Wireless devices may cause interference on sensitive medical equipment, so

please be aware of the restrictions on the use of wireless devices when in

hospitals, clinics or other healthcare facilities.

Cellular or mobile terminals operating over radio signal and cellular network cannot

be guaranteed to connect in certain conditions, such as when the mobile bill is

unpaid or the (U)SIM card is invalid. When emergency help is needed in such

conditions, use emergency call if the device supports it. In order to make or receive

a call, the cellular terminal or mobile must be switched on in a service area with

adequate cellular signal strength. In an emergency, the device with emergency call

function cannot be used as the only contact method considering network

connection cannot be guaranteed under all circumstances.

The cellular terminal or mobile contains a transceiver. When it is ON, it receives

and transmits radio frequency signals. RF interference can occur if it is used close

to TV sets, radios, computers or other electric equipment.

In locations with explosive or potentially explosive atmospheres, obey all posted

signs and turn off wireless devices such as mobile phone or other cellular

terminals. Areas with explosive or potentially explosive atmospheres include

refueling areas, below decks on boats, fuel or chemical transfer or storage

facilities, and areas where the air contains chemicals or particles such as grain,

dust or metal powders.
