DOCUMENT CONTROL FOR PROCUREMENT
Match the file to the product and order before approval.
- 01Confirm the model.The public FCC files on this page are identified for J25 and FCC ID 2BVP9-J25.
- 02Record the report number.Use R01 for Bluetooth LE, R02 for LoRa, R03 for WPT and R04 for EMF.
- 03Confirm the destination market.FCC evidence supports U.S. review; other markets require their own frequency and documentation check.
- 04Match the supplied configuration.Battery, accessories, packaging, app build and radio configuration must match the quotation.
- 05Keep the revision with the quotation.Procurement should retain the reviewed files together with the approved product, quantity and payment record.
PUBLIC VS CONTROLLED DOCUMENTS
Not every supporting file should be treated as universal.
Why the battery files are not posted here: the transport summary currently available must be matched to the exact cell and finished-product battery configuration before it can be represented as supporting the supplied J25. ChatField will not publish that relationship until it is verified.

Document questions from procurement teams
Which J25 product PDF should we use?
Use the J25 Product Introduction dated 2026-07-23 and marked FCC aligned. It is the current public product document linked on this page.
Are the four FCC files certificates?
They are original FCC test and evaluation reports for their stated scopes. This page deliberately labels them as reports rather than presenting every file as a certificate.
What FCC radio values are confirmed for J25?
The referenced reports identify LoRa operation at 903–927.5 MHz using CSS across 16 channels and Bluetooth Low Energy operation at 2402–2480 MHz using GFSK across 40 channels.
Why is the UN38.3 battery report not available as a public download?
Battery transport evidence must match the exact battery and finished-product configuration supplied with the order. ChatField will provide the appropriate controlled file only after that match is verified.
Can FCC files be used for a non-U.S. order?
FCC evidence supports U.S. regulatory review. It does not replace the frequency, conformity and documentation requirements of another destination market.
How do we request an order-specific document pack?
Provide the destination country, J25 quantity, quotation or configuration reference, intended use and requested document list through the B2B inquiry page, email or WhatsApp.
