1.1. Safety Information
The following safety precautions must be observed during all phases of operation, such as usage, service
or repair of any cellular terminal or mobile incorporating EC200T Mini PCIe module. 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 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. Please comply with laws and regulations
restricting the use of wireless devices while driving.
Switch off the cellular terminal or mobile before boarding an aircraft. The operation
of wireless appliances in an aircraft is forbidden to prevent interference with
communication systems. If the device offers an Airplane Mode, then it should be
enabled prior to boarding an aircraft. Please consult the airline staff for more
restrictions on the use of wireless devices on boarding the 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.
The cellular terminal or mobile contains a transmitter and receiver. When it is ON, it
receives and transmits radio frequency signals. 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.

3.3. Operating Modes
The following table briefly outlines the operating modes to be mentioned in the following chapters.
Table 5: Overview of Operating Modes
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=0 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=4 command or W_DISABLE# pin can set the module to 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. In this mode, the module can still receive paging message, SMS, voice call and
TCP/UDP data from the network normally.
3.4. Power Saving
3.4.1. Sleep Mode
EC200T Mini PCIe is able to reduce its current consumption to a minimum value in sleep mode. There are
three preconditions must be met to make the module enter sleep mode.
Execute AT+QSCLK=1 to enable sleep mode.
Ensure the DTR is kept at high level or be kept open.

3.4.2. Airplane Mode
When the module enters airplane mode, the RF function will be disabled, and allAT commands related to
it will be inaccessible. For more details, please refer to Chapter 3.10.3.
3.5. Power Supply
The following table shows pin definition of VCC_3V3 pins and ground pins.
Table 6: Definition of VCC_3V3 and GND Pins
The typical supply voltage of EC200T Mini PCIe is 3.3V. In the 2G network, the input peak current may
reach 2.7A during the transmitting time. Therefore, the power supply must be able to provide a rated
output current of 2.7A at least, and a bypass capacitor of no less than 470µF with low ESR should be
used to prevent the voltage from dropping. If the switching power supply is used to supply power to the
module, the power device and power supply routing traces of the switching power supply should be kept
away from the antennas as much as possible to prevent EMI interference.
The following figure shows a reference design of power supply where R2 and R3 are 1% tolerance
resistors and C3 is a low-ESR capacitor.
