The 4 VBAT pads supply the power to RF and baseband circuits directly. On VBAT pads, the ripple current up to 2A typically, So the power supply for these pads must be able to provide sufficient current up to more than 2A in order to avoid the voltage drop is more than 300mV. The following figure shows the VBAT voltage ripple wave at the maximum power transmit phase. 577us 4.615ms IVBAT VBAT Burst:2A Max:300mV Figure 5: VBAT voltage drop during burst emission Note: The test condition: The voltage of power supply for VBAT is 3.8V, Cd=100 F tantalum capacitor (ESR=0.7) and Cf=100nF (Please refer to Figure 6Application circuit).

20 uA SIM7600E-H_User Manual_V1.00 2017-10-11 Smart Machine Smart Decision 3.1.1 Power Supply Design Guide Make sure that the voltage on the VBAT pins will never drop below 3.4V, even during a transmit burst, when current consumption may rise up to 2A. If the voltage drops below 3.4V, the RF performance may be affected. Note: If the power supply for VBAT pins can support up to 2A, using a total of more than 300uF capacitors is recommended, or else users must using a total of 1000uF capacitors typically, in order to avoid the voltage drop is more than 300mV. Some multi-layer ceramic chip (MLCC) capacitors (0.1/1uF) with low ESR in high frequency band can be used for EMC. These capacitors should be put as close as possible to VBAT pads. Also, users should keep VBAT trace on circuit board wider than 2 mm to minimize PCB trace impedance. In addition, in order to guard for over voltage protection, it is suggested to use a zener diode with 5.1V reverse zener voltage and more than 500mW power dissipation.

It is important to make sure that all the components used in the power supply circuit can resist a peak current up to 2A. If there is a big voltage difference between input and output for VBAT power supply, or the efficiency is extremely important, then a switching mode power supply will be preferable. The following figure shows the switching mode power supply reference circuit. Note: The Switching Mode power supply solution for VBAT must be chosen carefully against Electro Magnetic Interference and ripple current from depraving RF performance. 3.1.3 Voltage Monitor To monitor the VBAT voltage, the AT command AT+CBC can be used. For monitoring the VBAT voltage outside or within a special range, the AT command AT+CVALARM can be used to enable the under-voltage warning function. If users need to power off SIM7600E-H, when the VBAT voltage is out of a range, the AT command AT+CPMVT can be used to enable under-voltage power-off function. Note: Under-voltage warning function and under-voltage power-off function are disabled by default. For more information about these AT commands, please refer to Document [1]. SIM7600E-H_User Manual_V1.00 2017-10-11 3.2 Power on/Power off/Reset Function 3.2.1 Power on Smart Machine Smart Decision SIM7600E-H can be powered on by pulling the PWRKEY pin down to ground. The PWRKEY pin has been pulled up with a diode to 1.8V internally, so it does not need to be pulled up externally. It is strongly recommended to put a100nF capacitor, an ESD protection diode, close to the PWRKEY pin as it would strongly enhance the ESD performance of PWRKEY pin. Note: Module could be automatically power on by connecting PWRKEY pin to ground via 0R resistor directly. The power-on scenarios are illustrated in the following figure. VBAT PWRKEY

Method 2: Power off SIM7600E-H by AT command AT+CPOF. Method 3: over-voltage or under-voltage automatic power off. The voltage range can be set by AT command AT+CPMVT. Method 4: over-temperature or under-temperature automatic power off. Note: If the temperature is outside the range of -30~+80, some warning will be reported via AT port. If the temperature is outside the range of -40~+85, SIM7600E-H will be powered off automatically. For details about AT+CPOF and AT+CPMVT, please refer to Document [1]. These procedures will make modules disconnect from the network and allow the software to enter a safe state, and save data before module be powered off completely.

When module has been powered on and firmware goes ready, STATUS will be high level, or else STATUS will still low level. 3.2.3 Reset Function SIM7600E-H can be reset by pulling the RESET pin down to ground. Note: This function is only used as an emergency reset, when AT command AT+CPOF and the PWRKEY pin all have lost efficacy. The RESET pin has been pulled up with a 40K resistor to 1.8V internally, so it does not need to be pulled up externally. It is strongly recommended to put a100nF capacitor and an ESD protection diode close to the RESET pin.

Software is active. Module is registered to the network, and the module is ready to communicate. Connection between two subscribers is in progress. In this case, the power consumption depends on network settings such as DTX off/on, FR/EFR/HR, hopping sequences, and antenna. Module is ready for data transmission, but no data is currently sent or received. In this case, power consumption depends on network settings. There is data transmission in progress. In this case, power consumption is related to network settings (e.g. power control level);

uplink/downlink data rates, etc. Minimum functionality mode AT command AT+CFUN=0 AT+CSCLK=1 can be used to set the module to a minimum functionality mode without removing the SIM7600E-H_User Manual_V1.00 2017-10-11 Smart Machine Smart Decision power supply. In this mode, the RF part of the module will not work and the USIM card will not be accessible, but the serial port and USB port are still accessible. The power consumption in this mode is lower than normal mode. AT command AT+CFUN=4 or pulling down the FLIGHTMODE pin can be used to set the module to flight mode without removing the power supply. In this mode, the RF part of the module will not work, but the serial port and USB port are still accessible. The power consumption in this mode is lower than normal mode. Module will go into power off mode by sending the AT command AT+CPOF or pull down the PWRKEY pin, normally. In this mode the power management unit shuts down the power supply, and software is not active. The serial port and USB are is not accessible. Flight mode Power off 5.3.2 Sleep mode In sleep mode, the current consumption of module will be reduced to the minimal level, and module can still receive paging message and SMS.

Safety Caution Table 43: Safety Caution 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.

Contains Transmitter Module FCC ID: 2AJYU-8PYA009 or Contains FCC ID: 2AJYU-8PYA009 8. Information on test modes and additional testing requirements a)The modular transmitter has been fully tested by the module grantee on the required number of channels,modulation types, and modes, it should not be necessary for the host installer to re-test all the available transmitter modes or settings. It is recommended that the host product manufacturer, installing the modular transmitter,perform some investigative measurements to confirm that the resulting composite system does not exceed the spurious emissions limits or band edge limits (e.g., where a different antenna may be causing additional emissions). b)The testing should check for emissions that may occur due to the intermixing of emissions with the other transmitters, digital circuitry, or due to physical properties of the host product (enclosure). This investigation is especially important when integrating multiple modular transmitters where the certification is based on testing each of them in a stand-alone configuration. It is important to note that host product manufacturers should not assume that because the modular transmitter is certified that they do not have any responsibility for final product compliance. c)If the investigation indicates a compliance concern the host product manufacturer is obligated to mitigate the issue. Host products using a modular transmitter are subject to all the applicable individual technical rules as well as to the general conditions of operation in Sections 15.5, 15.15, and 15.29 to not cause interference. The operator of the host product will be obligated to stop operating the device until the interference have been corrected . 9. Additional testing, Part 15 Sub part B disclaimer The final host / module combination need to be evaluated against the FCC Part 15B criteria for unintentional radiators in order to be properly authorized for operation as a Part 15 digital device. Smart Machine Smart Decision The host integrator installing this module into their product must ensure that the final composite product complies with the FCC requirements by a technical assessment or evaluation to the FCC rules, including the transmitter operation and should refer to guidance in KDB 996369. For host products with certified modular transmitter, the frequency range of investigation of the composite system is specified by rule in Sections 15.33(a)(1) through

(a)(3), or the range applicable to the digital device, as shown in Section 15.33(b)(1), whichever is the higher frequency range of investigation When testing the host product, all the transmitters must be operating.The transmitters can be enabled by using publicly-available drivers and turned on, so the transmitters are active. In certain conditions it might be appropriate to use a technology-specific call box (test set) where accessory 50 devices or drivers are not available. When testing for emissions from the unintentional radiator, the transmitter shall be placed in the receive mode or idle mode, if possible. If receive mode only is not possible then, the radio shall be passive (preferred) and/or active scanning. In these cases, this would need to enable activity on the communication BUS (i.e., PCIe, SDIO, USB) to ensure the unintentional radiator circuitry is enabled. Testing laboratories may need to add attenuation or filters depending on the signal strength of any active beacons (if applicable) from the enabled radio(s). See ANSI C63.4, ANSI C63.10 and ANSI C63.26 for further general testing details. The product under test is set into a link/association with a partnering device, as per the normal intended use of the product. To ease testing, the product under test is set to transmit at a high duty cycle, such as by sending a file or streaming some media content. FCC Statement:

Any Changes or modifications not expressly approved by the party responsible for compliance could void the users authority to operate the equipment. This device complies with part 15 of the FCC Rules. Operation is subject to the following two conditions: (1) This device may not cause harmful interference, and

(2) This device must accept any interference received, including interference that may cause undesired operation
