The SDoC verification is based on a single sample test. It does not imply assessment of the entire production batch. The responsible party (Guangdong Bestek Technology Co., Ltd.) is obligated to retain the full test report and supporting documentation for submission to the FCC upon request.
Standards & Compliance
The Helios J1 was tested and found compliant with the following standards and regulations:
- 47 CFR Part 15 Subpart B (October 2020) — Unintentional radiators: limits and measurement methods for electromagnetic emissions from digital devices
- ANSI C63.4:2014 + A1:2017 — American National Standard for methods of measurement of radio-noise emissions from low-voltage electrical and electronic equipment
- FCC Section 2.906 — Requirements governing the Supplier’s Declaration of Conformity procedure
- FCC Section 15.19(a) — Labeling requirements applicable to all Part 15 devices
As an SDoC device, the Helios J1 may voluntarily display the FCC logo, provided full compliance with SDoC procedures is maintained. Use of the logo is restricted to fully compliant products only.

Frequently Asked Questions
- Q: What does FCC SDoC mean for the Helios J1?
- FCC SDoC (Supplier’s Declaration of Conformity) means that Guangdong Bestek Technology Co., Ltd., as the responsible party, has tested the Helios J1 against FCC Part 15 Subpart B limits and self-declares compliance. The product is legally authorized for sale and use in the United States without requiring a separate FCC license.
- Q: Which FCC rule part applies to the Helios J1?
- The Helios J1 is certified under 47 CFR Part 15 Subpart B, which governs unintentional radiators — electronic devices that generate radio frequency energy as a byproduct of their operation rather than for intentional transmission.
- Q: Does the FCC SDoC cover all units manufactured?
- No. The VoC is based on a single sample test and does not constitute an assessment of the entire production run. The responsible party must ensure that all manufactured units conform to the tested design and are produced under consistent quality controls.
- Q: Can the Helios J1 display the FCC logo on its label?
- Yes, on a voluntary basis. Devices subject to SDoC authorization may display the official FCC logo, but only if the product fully complies with all SDoC procedures as outlined in FCC rules. The label must also meet the requirements of Section 15.19(a).
