Figure 2-7 The reference circuit of USB interface 4The USB interface input the voltage from USB_IN .For keeping the USB in U9507E module working unfailingly, a voltage protection circuit should be added by user between the USB_IN of USB interface and the USB_VBUS PIN of U9507E. It is shown in figure 2-8 with the red circle 2. In the voltage protection circuit, D603 is a Zener diode with a breakdown voltage value of 5.1v which could keep the voltage on the USB_VBUS PIN of U9507E not more than 5.1v. D602 is a Schottky Diode, and R621 is a resistor with the value 1K. On the other hand the voltage coming from the USB_IN also could be converted by using a DC/DC converter to 3.6v and then be sent to VBAT PIN of U9507E.

The AT command can be used in three ways. as Performing AT+CPBS? will

+CPBS:<storage>[,<used>,<total>].The parameter <total> indicated how many phone numbers can be stored on the phone. The parameter <used> indicates how many phone numbers have been stored. Performing AT+CPBS=? will return all the storage type which the phone supports. Such as +CPBS(list of supported

<storage>s). We can use AT+CPBS=<storage> to set storage location. There are six types storage location. Its follow as:

LD MC RC ON ME SM

--store the recently call number which have dialed (SIM).

--store the recently call number which havent answered.

--store the recently call number which have been answered.

Performing AT+CPBR=? will list of supported index, phone number length and text length. Performing AT+CPBR=<index1>[,<index2>] will return the content of the phonebook entry of index1. If we use index1 and index2 at the same time ,it will return all the entries between index1 and index2. Such as

[+CPBR:<index1>,<number>,<type><text>[[...]<CR><LF>+CPBR:<index2>,<number>,<type><text>]]

The parameter <type> include 129 and 145.145 indicate which is a international phone number. 129 indicate which is a unknown type number. The parameter <text> is the tag of the number. 4.3.3 Write phonebook entry When you want to write a phonebook entry on the phone, you can use AT commande AT+CPBW. Performing AT+CPBW=? will return list of supported index, max length of phone number, list of supported phone number types and max length of text. We can use the command AT+CPBW=[<index>][,<number>[,<type>[,<text>]]] to write number on the phone. If the parameter <number> is NULL, the command will delete the phone number on the phone of index. Page 27 of 32 4.3.4 Find phonebook entries We can use AT command AT+CPBF when we want to find the entry according to the text. Performing AT+CPBF=? will return the max length of phone number and the max length of text. Such as

+CPBF:[<nlength>],[<tlength>]. When we want to find a entry, we can give the text of the phone number ,and according to the text, we use AT+CPBF=<findtext> to find the number we want. 4.4 AUDIO Audio functions are only available in the U9507E module. 4.4.1 Originate Call ATD<str>[;] Mobile originate call to dial a number. <str>: string of dialing digits, dialing digits:09

(Unit: mm) Top View Side View Bottom View FCC Certification Requirements. According to the definition of mobile and fixed device is described in Part 2.1091(b), this device is a mobile device. And the following conditions must be met:

1. This Modular Approval is limited to OEM installation for mobile and fixed applications only. The antenna installation and operating configurations of this transmitter, including any applicable source-based time-

averaging duty factor, antenna gain and cable loss must satisfy MPE categorical Exclusion Requirements of 2.1091. 2. The EUT is a mobile device; maintain at least a 20 cm separation between the EUT and the users body Page 30 of 32 and must not transmit simultaneously with any other antenna or transmitter. 3.A label with the following statements must be attached to the host end product: This device contains FCC ID: XHZU9507E. 4.To comply with FCC regulations limiting both maximum RF output power and human exposure to RF radiation, maximum antenna gain (including cable loss) must not exceed:

WCDMA Band 5 (Tx: 824 MHz ~ 849 MHz): <1dBi LTE Band 5 (Tx: 824 MHz ~ 849 MHz): <1dBi LTE Band 7(Tx: 2500 MHz ~ 2570 MHz): <5dBi 5. This module must not transmit simultaneously with any other antenna or transmitter 6. The host end product must include a user manual that clearly defines operating requirements and conditions that must be observed to ensure compliance with current FCC RF exposure guidelines. For portable devices, in addition to the conditions 3 through 6 described above, a separate approval is required to satisfy the SAR requirements of FCC Part 2.1093 If the device is used for other equipment that separate approval is required for all other operating configurations, including portable configurations with respect to 2.1093 and different antenna configurations. For this device, OEM integrators must be provided with labeling instructions of finished products. Please refer to KDB784748 D01 v07, section 8. Page 6/7 last two paragraphs:

A certified modular has the option to use a permanently affixed label, or an electronic label. For a permanently affixed label, the module must be labeled with an FCC ID - Section 2.926 (see 2.2 Certification (labeling requirements) above). The OEM manual must provide clear instructions explaining to the OEM the labeling requirements, options and OEM user manual instructions that are required (see next paragraph). For a host using a certified modular with a standard fixed label, if (1) the modules FCC ID is not visible when installed in the host, or (2) if the host is marketed so that end users do not have straightforward commonly used methods for access to remove the module so that the FCC ID of the module is visible; then Page 31 of 32 an additional permanent label referring to the enclosed module:Contains Transmitter Module FCC ID:

XHZU9507E or Contains FCC ID: XHZU9507E must be used. The host OEM user manual must also contain clear instructions on how end users can find and/or access the module and the FCC ID. The final host / module combination may also 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. The users manual or instruction manual for an intentional or unintentional radiator shall caution the user that changes or modifications not expressly approved by the party responsible for compliance could void the user's authority to operate the equipment. In cases where the manual is provided only in a form other than paper, such as on a computer disk or over the Internet, the information required by this section may be included in the manual in that alternative form, provided the user can reasonably be expected to have the capability to access information in that form. 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. Changes or modifications not expressly approved by the manufacturer could void the users authority to operate the equipment. To ensure compliance with all non-transmitter functions the host manufacturer is responsible for ensuring compliance with the module(s) installed and fully operational. For example, if a host was previously authorized as an unintentional radiator under the Declaration of Conformity procedure without a transmitter certified module and a module is added, the host manufacturer is responsible for ensuring that the after the module is installed and operational the host continues to be compliant with the Part 15B unintentional radiator requirements.
