Warning

The WL1837MODCOM8I board is tested to comply with ETSI/R&TTE over temperatures from –40°C to +85°C.

This board must not be modified to operate in other frequency bands other than designed for.

FCC Licensing Requirements for the Wi-Fi and Bluetooth Radio Module of the EVM:

For evaluation only; not FCC approved for resale. This kit is designed to allow:

  1. Product developers to evaluate electronic components, circuitry, or software associated with the kit to determine whether to incorporate such items in a finished product
  2. Software developers to write software applications for use with the end product. This kit is not a finished product and when assembled cannot be resold or otherwise marketed unless all required FCC equipment authorizations are first obtained. Operation is subject to the condition that this product not cause harmful interference to licensed radio stations and that this product accept harmful interference. Unless the assembled kit is designed to operate under part 15, part 18, or part 95 of this chapter, the operator of the kit must operate under the authority of an FCC license holder or must secure an experimental authorization under part 5 of this chapter.

Per TI’s Regulatory Compliance Information located in the WL1837MODCOM8I User’s Guide’s “Evaluation Board/Kit/Module (EVM) Additional Terms,” this EVM cannot be used for production purposes and is explicitly restricted from end-product introduction.

Use of this EVM requires the developer to provide a minimum distance of at least 20 cm from the antenna to all persons to minimize risk of potential radiation hazards.

CAUTION:

Do not leave the EVM powered when unattended.

NCC Statement

  1. 取得審驗證明之低功率射頻器材,非經核准,公司、商號或使用者均不得擅自變更頻率、加大功率或變更原設 計之特性及功能。

    For low-power radio frequency equipment that has obtained certification, no company, firm or user can change the frequency, increase the power, or change the characteristics and functions of the original design without approval.

  2. 低功率射頻器材之使用不得影響飛航安全及干擾合法通信;經發現有干擾現象時,應立即停用,並改善至無干擾時方得繼續使用。前述合法通信,指依電信管理法規定作業之無線電通信。低功率射頻器材須忍受合法通信或工業、科學及醫療用電波輻射性電機設備之干擾。

    The use of low-power radio frequency equipment must not affect flight safety or interfere with legitimate communications; if interference is found, then the interference must be stopped immediately and improved until there is no interference before continued use. The aforementioned legal communications refer to radio communications operated in accordance with the provisions of the Telecommunications Management Act. Low-power radio frequency equipment must endure interference from electromagnetic equipment that radiates electromagnetic waves for legitimate communications or industrial, scientific and medical purposes.

  3. 無線資訊傳輸設備必須避免影響附近雷達系統的運行。

    Wireless information transmission equipment must avoid affecting the operation of nearby radar systems.

NCC Labeling Requirements

If using a permanently affixed label, then the modular transmitter must be labeled with the NCC identification number. If the NCC identification number is not visible when the module is installed inside another device, then the outside of the device into which the module is installed must also display a label referring to the enclosed module.

This exterior label can use wording such as the following:

"Contains Transmitter Module NCC ID: CC XX xx YY yyy Z z W" or "Contains NCC ID: CC XX xx YY yyy Z z W." Any similar wording that expresses the same meaning can be used.
