Safety Information
The following safety precautions must be observed during all phases of operation, such as usage, service
or repair of any terminal or mobile incorporating the module. Manufacturers of the terminal should notify
users and operating personnel of the following safety information by incorporating these guidelines into all
manuals of the product. Otherwise, Quectel assumes no liability for customers’ 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 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 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.
Terminals or mobiles 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
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 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 terminals. Areas
with explosive or potentially explosive atmospheres include fueling 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.
