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 M72 module.
Manufactures of the cellular terminal should send 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 about the
use of mobile. Switch the cellular terminal or mobile off. Medical equipment may
operate abnormally as a consequence of 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 in
order to prevent the aircraft communication system from interference. 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.
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.
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 signals and cellular
networks. Because of this, 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 a call, the cellular terminal or mobile must be switched on and
in a service area with adequate cellular signal strength.
Some networks do not allow to make an 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.
