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.

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

User’s 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 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
