With the assistance of the document and other instructions, the developers can quickly understand the hardware functions of L610 modules and develop product By following the safety guidelines below, you can ensure your personal safety and help protect the product and work environment from potential damage. Product manufacturers need to communicate the following safety instructions to end users. In case of failure to comply with these safety rules, Fibocom will not be responsible for the consequences caused by the users misuse. Road safety first! When you drive, do not use the handheld devices even if it has a hand-free feature. Please stop and call. Please turn off the mobile device before boarding. The wireless feature of the mobile device is not allowed on the aircraft to prevent interference with the aircraft communication system. Ignoring this note may result in flight safety issue or even violate the law. When in a hospital or health care facility, please be aware of restrictions on the use of mobile devices. Radio frequency interference may cause medical equipment to malfunction, so it may be necessary to turn off the mobile device. The mobile device does not guarantee that an effective connection can be made under any circumstances, for example, when there is no prepayment for the mobile device or the (U)SIM is invalid. When you encounter the above situation in an emergency, remember to use an emergency call, while keeping your device turned on and in areas where signal is strong. Your mobile device receives and transmits RF signals when it is powered on. Radio interference occurs when it is near televisions, radios, computers, or other Reproduction forbidden without Fibocom Wireless Inc. written authorization - All Rights Reserved FIBOCOM L610-LA Series Hardware Guide Page 7 of 49 electronic devices. Keep the mobile device away from flammable gases. Turn off the mobile device when you get near to gas stations, oil depots, chemical plants or explosive workplaces. There are potential safety hazards when operating electronic equipment in any potentially explosive area. 1.3 Reference Standard This design of the product complies with the following standards:

Since the antenna cable loss is less than 0.3dB, keep the PCB routing as short as possible.

Recommended antenna gain 2.5dBi. 6) Interference Antenna directivity refers to the electromagnetic field strength of electromagnetic wave in all directions. In addition to the antenna performance, other interferences on the PCB also may affect the performance of the module. In order to ensure the high performance of the module, interference must be controlled.

This device is intended only for OEM integrators under the following conditions:

1) The antenna must be installed such that 20 cm is maintained between the antenna and users, and the maximum antenna gain allowed as below table. 2) The transmitter module may not be co-located with any other transmitter or antenna. As long as 2 conditions above are met, further transmitter test will not be required. However, the OEM integrator is still responsible for testing their end-product for any additional compliance requirements Reproduction forbidden without Fibocom Wireless Inc. written authorization - All Rights Reserved FIBOCOM L610-LA Series Hardware Guide Page 48 of 49 required with this module installed. IMPORTANT NOTE: In the event that these conditions can not be met (for example certain laptop configurations or co-location with another transmitter), then the FCC authorization is no longer considered valid and the FCC ID can not be used on the final product. In these circumstances, the OEM integrator will be responsible for re-evaluating the end product (including the transmitter) and obtaining a separate FCC authorization. End Product Labeling This transmitter module is authorized only for use in device where the antenna may be installed such that 20 cm may be maintained between the antenna and users. The final end product must be labeled in a visible area with the following: Contains FCC ID: ZMOL610LA. The grantee's FCC ID can be used only when all FCC compliance requirements are met. Manual Information To the End User The OEM integrator has to be aware not to provide information to the end user regarding how to install or remove this RF module in the users manual of the end product which integrates this module. The end user manual shall include all required regulatory information/warning as show in this manual. This device is intended only for OEM integrators under the following conditions:

Yes, The required FCC rule has been fulfilled and all the instruction for maintaining compliance have been clearly stated in the user manual. Yes, Please refer exhibition RF exposure for the compliance of MPE RF exposure rule. 2. 3. 4. 5. 8. Modular Approval Request FCC (KDB 996369 D01 & Part 15.212) FCC ID: ZMOL610LA Items to be covered by Single modular transmitters. 1. The modular transmitter must have its own RF shielding. The modular transmitter must have buffered modulation/data inputs (if such inputs are provided) to ensure that the module will comply with Part 15 requirements under conditions of excessive data rates or over-modulation. The modular transmitter must have its own power supply regulation. The modular transmitter must comply with the antenna requirements of Section 15.203 and 15.204(b)(c). The antenna must either be permanently attached or employ a unique antenna coupler (at all connections between the module and the antenna, including the cable). The modular transmitter must be tested in a stand-alone configuration, i.e., the module must not be inside another device during testing. This is intended to demonstrate that the module is capable of complying with Part 15 emission limits regardless of the device into which it is eventually installed. 6. The modular transmitter must be equipped with either a permanently affixed label or must be capable of electronically displaying its FCC identification number in accordance with 15.212 (a)(1)(vi)(A) / (B). 7. The modular transmitter must comply with any specific rule or operating requirements applicable to the transmitter and the manufacturer must provide adequate instructions along with the module to explain any such requirements. A copy of these instructions must be included in the application for equipment authorization. For example, there are very strict operational and timing requirements that must be met before a transmitter is authorized for operation under Section 15.231. For instance, data transmission is prohibited, except for operation under Section 15.231(e), in which case there are separate field strength level and timing requirements. Compliance with these requirements must be assured. The modular transmitter must comply with any applicable RF exposure requirements. For example, FCC Rules in Sections 1.1310, 2.1091, 2.1093, and specific Sections of Part 15, including 15.319(i), 15.407(f), 15.253(f) and 15.255(g), require that Unlicensed PCS, UNII and millimeter wave devices perform routine environmental evaluation for RF Exposure to demonstrate compliance. In addition, spread spectrum transmitters operating under Section 15.247 are required to address RF Exposure compliance. Modular transmitters approved under other Sections of Part 15, when necessary, may also need to address certain RF Exposure concerns, typically by providing specific installation and operating instructions for users, installers and other interested parties to ensure compliance. RF_734_02 04 April 16 Note: A limited modular approval (LMA) may be granted for single modular transmitters that comply partially with the requirements above.
