Regulatory Compliance: The module complies with Japanese and US radio equipment regulations, including ARIB STD-T108 and FCC Part 15C. Users must adhere to these regulations to ensure legal operation.

Labeling and User Information Requirements: The module must display its FCC ID number. If not visible, the finished product must have an exterior label referring to the enclosed module. User manuals should include specific FCC compliance statements.

RF Exposure: Compliance with FCC RF exposure requirements is mandatory. The module's output power is conducted, and it must be installed by OEM integrators. It should not be co-located with other antennas or transmitters unless following FCC procedures.

Approved External Antenna Types: Only tested antenna types should be used to maintain modular approval. Different manufacturers are permissible if the antenna type and gain are consistent with tested specifications.

RF Trace Layout Design: The transmitter is certified with a specific PCB edge SMA connector and micro-strip trace layout. Host PCBs should follow this design to maintain compliance.

Firmware Licensing: The firmware is dedicated to BP35C5 and should not be used for other products. Redistribution, reverse engineering, and modification are prohibited. ROHM does not guarantee operations performed with this software.

Firmware Version: The firmware version is the latest at manufacturing time but may vary with shipment timing. Changes in firmware versions are not notified, and ROHM is not liable for any resulting damages.

Method for Checking Firmware Version: The firmware version can be checked using the "vers" command as detailed in the command manual.

Number of Rewritable Firmware: The firmware can be rewritten up to 1,000 times. Beyond this, ROHM does not guarantee product operation.

Precautions: The product may experience radio wave interference and requires certification under the Radio Act for use. Storage conditions are specified, and baking treatment is recommended if packaging is opened beyond specified time limits.

Notice: ROHM products are designed for ordinary electronic equipment and not for high-reliability applications without prior consultation. Products are not designed for special environments, and users must verify performance independently.

Precautions for Mounting/Circuit Board Design: Use appropriate soldering methods and consult ROHM for deviations. Application examples are for guidance only, and users must verify independently.

Precautions for Manufacturing and Storage: Ensure that voltage does not exceed the product's maximum rating, especially under dry conditions. Implement grounding, isolation, ionization, friction prevention, and temperature/humidity control.

Storage and Transportation Precautions:

Avoid storing products in environments with sea winds, corrosive gases, excessive temperature/humidity, direct sunlight, or high electrostatic conditions.
Check solderability if storage exceeds recommended time.
Store/transport cartons correctly to prevent damage.
Use products promptly after opening humidity barrier bags; baking may be required if storage time is exceeded.

Product Label Precaution: The barcode on ROHM product labels is for internal use only.

Disposition Precaution: Dispose of products properly through authorized waste companies.
