3 Operation Method
3.1 Module Boot
3.1.1Module Power-on Operation
The module boot method is as follows ：
1. Insert the Micro USB into the USB connector J103 (or J104) 。
2. Turn the switch SW101 up to the on state, and LED101, LED102, and LED103 will light up.
3. If the module is successfully registered to the network, the flashing frequency of LED101 will slow down, otherwise LED101 will keep flashing fast. When the module enters PSM mode or the module is in shutdown state, LED101 will go out.
The module shutdown method is as follows:
1. Turn the switch SW101 down to the off state, the module will automatically shut down, and LED101,
LED102, and LED103 will go out.
2. The module can be powered off by the AT command. When the module is in the power-on state, input the
AT command "AT+CPOF" and the module will automatically power off. More details. Please refer to
SIM7022 series _AT command.

4.3 Safety Warning
Table 20: safety warning
Marks Requirements
When in a hospital or other health care facility, observe the restrictions about the use of mobiles. Switch the cellular terminal or mobile off, medical equipment may be sensitive and not operate normally due to RF energy interference.
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 to prevent interference with communication systems. Forgetting to think much of these instructions may impact the flight safety, or offend local legal action, or both.
Do not operate the cellular terminal or mobile in the presence of flammable gases or fumes.
Switch off the cellular terminal when you are near petrol stations, fuel depots, chemical plants or where blasting operations are in progress. Operation of any electrical equipment in potentially explosive atmospheres 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 sets, radios, computers or other electric equipment.
Road safety comes first! Do not use a hand-held cellular terminal or mobile when 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 over radio frequency signals and cellular networks and cannot be guaranteed to connect in all conditions, especially with a mobile fee or an invalid SIM card. While you are in this condition and need emergent help, please remember to use emergency calls. 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 the cellular terminal or mobile.
