Label and compliance information FCC ID label on the final system must be labeled with Contains FCC ID:

2A5RA-BS003B or Contains transmitter module FCC ID: 2A5RA-BS003B. Information on test modes and additional testing requirements Contact ZHONGSHAN HONG ZHE ELECTRIC Co.,Ltd will provide stand-alone modular transmitter test mode. Additional testing and certification may be necessary when multiple modules are used in a host. Additional testing, Part 15 Subpart B disclaimer 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 Suppliers 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. Since this may depend on the details of how the module is integrated with the host, ZHONGSHAN HONG ZHE ELECTRIC Co.,Ltd shall provide guidance to the host manufacturer for compliance with the Part 15B requirements. FCC Warning 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. NOTE 1: Any changes or modifications to this unit not expressly approved by the party responsible for compliance could void the user's authority to operate the equipment. FCC Radiation Exposure Statement:

This equipment complies with FCC radiation exposure limits set forth for an uncontrolled environment. End users must follow the specific operating instructions for satisfying RF exposure compliance. Note 1: This module certified that complies with RF exposure requirement under 5mm RF distance. Note 2: Any modifications made to the module will void the Grant of Certification, this module is limited to OEM installation only and must not be sold to end-users, end-user has no manual instructions to remove or install the device, only software or operating procedure shall be placed in the end-user operating manual of final products.

Reference No.: WTH22X05090196W Page 1 of 6 ANNEX EXHIBIT 1 - PRODUCT LABELING Proposed FCC ID Label Format FCC ID: 2A5RA-BS003B Specifications: The label shall be securely affixed to a permanently attached part of the device, in a location where it is visible or easily accessible to the user, and shall not be readily detachable. The label shall be sufficiently durable to remain fully legible and intact on the device in all normal conditions of use throughout the devices expected lifetime.
