1.2. Safety precautions
The following safety precautions must be observed during all phases of the operation, such as
usage, service or repair of any cellular terminal or mobile incorporating M80 module.
Manufacturers of the cellular terminal are advised to convey the following safety information to
users and operating personnel and to incorporate these guidelines into all manuals supplied with
the product. If not so, Quectel does not take on any liability for customer failure to comply with
these precautions.
When in a hospital or other health care facility, observe the restrictions on the use
of mobile. Switch the cellular terminal or mobile off. Medical equipment may be
sensitive to RF energy interference.
Switch off the cellular terminal or mobile before boarding an aircraft. Make sure
it switched off. The operation of wireless appliances in an aircraft is forbidden to
prevent interference with communication systems. Forget to think much of these
instructions may influence the flight safety or offend against local legal action, or
both.
Do not operate the cellular terminal or mobile in the presence of flammable gas
or fume. Switch off the cellular terminal when you are near petrol station, fuel
depot, chemical plant or where blasting operations are in progress. Operation of
any electrical equipment in potentially explosive atmosphere can constitute a
safety hazard.

Road safety comes first! Do not use a hand-held cellular terminal or mobile
while driving a vehicle, unless it is securely mounted in a holder for hands-free
operation. Before making a call with a hand-held terminal or mobile, park the
vehicle.
GSM cellular terminals or mobiles operate using radio frequency signal and
cellular network. Because of this, the connection cannot be guaranteed in all
conditions, for example no mobile fee or an invalid SIM card. While you are in
this condition and need emergent help, please remember using emergency call.
In order to make or receive calls, the cellular terminal or mobile must be
switched on and in a service area with adequate cellular signal strength.
Some networks do not allow for emergency call if certain network services or
phone features are in use (e.g. lock functions, fixed dialing etc.). You may have
to deactivate those features before you can make an emergency call.
Also, some networks require that a valid SIM card be properly inserted in
cellular terminal or mobile.
Your cellular terminal or mobile receives and transmits radio frequency energy
while switched on. RF interference can occur if it is used close to TV set, radio,
computer or other electric equipment.
