Nothing Technology Limited Label Placement Declaration Print Name: Jathan Liu Product name: Wireless Earphone Model Name：B197 FCC ID:2AZEQ-B197L IC:27102-B197L HVIN:B197L The FCC ID&IC will not affix on the earbuds but described in the product user manual and the product package due to below reasons. The earbud is too small to put the ID label on it. Sincerely The subject device is extremely compact, with available labeling area significantly smaller than the palm of a hand, which the FCC guidance considers too small for the required compliance statement . Due to the device's physical dimensions, it is impracticable to print the full Part 15.19(a) Therefore, pursuant to 47 CFR § 15.19(a)(5), the required compliance statement has been placed in a prominent location within the user manual and is also printed on the product packaging Pursuant to RSS-Gen, the label text on a device must be legible without the aid of magnification. If the device is too small to meet this condition, the label information may be included in the user manual upon agreement with ISED. There fore, the following labeling information has been placed in a prominent location within the user manual and will also be printed on the product packaging. Note on Language Requirements: The user manual and all labeling information will be provided in both English and French, as required by ISED
