1.1. Safety Information
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 EC25 module. Manufacturers 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 assumes no liability for the
customer’s failure to comply with these precautions.
Full attention must be given to driving at all times in order to reduce the risk of an

the use of wireless devices on boarding the aircraft, if your device offers a Airplane
Mode which must be enabled prior to boarding an aircraft.

facilities. These requests are desinged to prevent possible interference with
