Intend to OEM Integrator Installation It’s not allowed to spread without the permission of ZTE Corporation. © ZTE Corporation. All rights reserved. 第III 页 Important compliance information for North American users The MW3736 Module has been granted modular approval for mobile applications. Integrators may use the MW3736 Module in their final products without additional FCC certification if they meet the following conditions. Otherwise, additional FCC approvals must be obtained. 1. At least 20cm separation distance between the antenna and the user’s body must be maintained at all times. 2. To comply with FCC regulations limiting both maximum RF output power and human exposure to RF radiation, the maximum antenna gain including cable loss in a mobile-only exposure condition must not exceed 3dBi in the GSM850/WCDMA850 band and 5dBi for GSM1900/WCDMA1900 band. 3. The MW3736 Module and its antenna must not be co-located or operating in conjunction with any other transmitter or antenna within a host device. This equipment complies with FCC RF radiation exposure limits set forth for an uncontrolled environment. 4. A label must be affixed to the outside of the end product into which the MW3736 Module is incorporated, with a statement similar to the following: For MW3736: This device contains FCC ID: Q78-MW3736. 5. A user manual with the end product must clearly indicate the operating requirements and conditions that must be observed to ensure compliance with current FCC RF exposure guidelines. The end product with an embedded MW3736 Module may also need to pass the FCC Part 15 unintentional emission testing requirements and be properly authorized per FCC Part 15. Note: If this module is intended for use in a portable device, you are responsible for separate approval to satisfy the SAR requirements of FCC Part 2.1093. FCC NOTICE: 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 made to this equipment not expressly approved by ZTE Corporation may void the FCC authorization to operate this equipment. 
