This equipment has been tested and found to comply with the limits for a Class digital device,
pursuant to Part 15 of the FCC rules. These limits are designed to provide reasonable
protection against harmful interference in a residential installation. This equipment generates
uses and can radiate radio frequency energy and, if not installed and used in accordance with
the instructions, may cause harmful interference to the radio communications. However, there
are no guarantees that interference will not occur in a particular installation.
Troubleshooting
If this equipment does cause harmful interference to radio reception, which can be
determined by turning the equipment off and on, the user is encouraged to correct the
interference by one or more of the following instructions.
．Reorient or relocate the receiving antenna.
．Increase the separation between the equipment and receiver.
．Consult dealer or an experienced radio technician.

7. NCC 警語
根據 NCC 低功率電波輻射性電機管理辦法規定
第十二條：
經型式認證合格之低功率射頻電機，非經許可，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。
第十四條：
低功率射頻電機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。前項合法通信，指依電信法規定作業之無線電通信。
低功率射頻電機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。
此模組於取得認證後將依規定於模組本體標示審驗合格標籤，並要求平台廠商於平台上標示。
