FCC ID: 2ANTU-20028186 Bluetooth Low Energy Radio Module

WATERPIK BLUETOOTH LOW ENERGY MODULE USER MANUAL The 20028186 module has been evaluated in stand-alone conditions. For different operational conditions from a stand-alone modular transmitter in a host (multiple, simultaneously transmitting modules, or other transmitters in a host), may require additional testing. 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. The modular transmitter is only FCC authorized for the specific rule parts (i.e., FCC transmitter rules) listed on the grant, and that the host product manufacturer is responsible for compliance to any other FCC rules that apply to the host not covered by the modular transmitter grant of certification. If the grantee markets their product as being Part 15 Subpart B compliant (when it also contains unintentional-radiator digital circuitry), then the grantee shall provide a notice stating that the final host product sill requires Part 15 Subpart B compliance testing with the modular transmitter installed. The end product with an embedded module may also need to pass the FCC Part 15 unintentional emission testing requirement and be properly authorized per FCC Part 15. Figure 1 - 20028186 Block Diagram This module is not intended to transmit simultaneously with any other antenna or transmitter. 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. 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 for modifications not expressly approved by the party responsible for compliance could void the users 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 1 Z2.4GHzPI FILTER NETWORKANTEM9304V01LF28BANTGPIO2GNDGPIO3VBAT2TMS/GPIO11TDI/GPIO10GPIO7TDO/GPIO9TCK/GPIO83VGPIO6GPIO5GPIO448.000MHz32.768kHzGPIO1GPIO0VIOEN3V3V 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. To ensure compliance with all non-transmitter functions the host manufacturer is responsible for ensuring compliance with the modules(s) installed and 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.

The following attestation addresses the requirements to support modular approval pursuant to 15.212 of the Commissions Rules:

Modular approval requirement [Yes] No*

(i) The radio elements of the modular transmitter must have their own shielding. The physical crystal and tuning capacitors may be located external to the shielded radio elements. x 4

(ii) 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 } X excessive data rates or over-modulation.

(iii) The modular transmitter must have its own power supply regulation. X

(iv) The modular transmitter must comply with the antenna and transmission system requirements of 15.203, 15.204(b) and 15.204(c). The antenna must either be permanently attached or employ a unique antenna coupler (at all connections between the module and the antenna, | X including the cable). The professional installation provision of 15.203 is not applicable to modules but can apply to limited modular approvals under paragraph (b) of this section. |

(v) The modular transmitter must be tested in a stand-alone configuration, i.e., the module must not be inside another device during testing for compliance with part 15 requirements. Unless the transmitter module will be battery powered, it must comply with the AC line conducted requirements found in 15.207. AC or DC power lines and data input/output lines connected to the module must not contain ferrites, unless they will be marketed with the module (see 15.27(a)). | X The length of these lines shall be the length typical of actual use or, if that length is unknown, at least 10 centimeters to insure that there is no coupling between the case of the module and supporting equipment. Any accessories, peripherals, or support equipment connected to the module during testing shall be unmodified and commercially available (see 15.31(i)).

(vi) The modular transmitter must be equipped with either a permanently affixed label or must be capable of electronically displaying its FCC identification number. | x

(vii) The modular transmitter must comply with any specific rules or operating requirements that ordinarily apply to a complete transmitter and the manufacturer must provide adequate x instructions along with the module to explain any such requirements. A copy of these instructions must be included in the application for equipment authorization. |

(viii) The modular transmitter must comply with any applicable RF exposure requirements in its x final configuration.
