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 EM05. Manufacturers of the cellular
terminal should send the following safety information to users and operating personnel, and incorporate
these guidelines into all manuals supplied with the product. If not so, Quectel assumes no liability for the
customers’ failure to comply with these precautions.
Full attention must be given 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. You must comply with laws and regulations
restricting the use of wireless devices while driving.
Switch off the cellular terminal or mobile before boarding an aircraft. Make sure it is
switched off. The operation of wireless appliances in an aircraft is forbidden, so as
to prevent interference with communication systems. Consult the airline staff about
the use of wireless devices on boarding the aircraft, if your device offers an
Airplane Mode which must be enabled prior to boarding an aircraft.
Switch off your wireless device when in hospitals, clinics or other health care
facilities. These requests are designed to prevent possible interference with
sensitive medical equipment.
Cellular terminals or mobiles operating over radio frequency signal and cellular
network cannot be guaranteed to connect in all conditions, for example no mobile
fee or with an invalid (U)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.
Your cellular terminal or mobile contains a transmitter and receiver. When it is ON,
it receives and transmits radio frequency energy. RF interference can occur if it is
used close to TV set, radio, computer or other electric equipment.
In locations with potentially explosive atmospheres, obey all posted signs to turn
off wireless devices such as your phone or other cellular terminals. Areas with
potentially explosive atmospheres include fuelling areas, below decks on boats,
fuel or chemical transfer or storage facilities, areas where the air contains
chemicals or particles such as grain, dust or metal powders, etc.

1. The typical supply voltage of VCC is 3.3V.
2. Keep all NC, reserved and unused pins unconnected.
3. “*” means under development.
4. EM05-CML does not support I2C interface.
3.3. Operating Modes
The table below briefly summarizes the various operating modes referred in the following chapters.
Table 5: Overview of Operating Modes
3.4. Power Saving
3.4.1. Sleep Mode
EM05 is able to reduce its current consumption to a minimum value during the sleep mode. The following
section describes power saving procedure of EM05 module.
Mode
Details
Normal
Operation
Idle
Software is active. The module has registered on the network, and it
is ready to send and receive data.
Talk/Data
Network connection is ongoing. In this mode, the power consumption
is decided by network setting and data transfer rate.
Minimum
Functionality
Mode
AT+CFUN command can set the module to a minimum functionality mode without
removing the power supply. In this case, both RF function and (U)SIM card will be
invalid.
Airplane Mode
AT+CFUN command or W_DISABLE1# pin can set the module into airplane mode. In
this case, RF function will be invalid.
Sleep Mode
In this mode, the current consumption of the module will be reduced to the minimal
level. During this mode, the module can still receive paging message, SMS, voice call
and TCP/UDP data from the network normally.
Power Down
Mode
In this mode, the power management unit shuts down the power supply. Software is
not active. Operating voltage (connected to VCC) remains applied.
