The design HQ-BLE-1 (590 54 13) is certified according to Japanese Radio, and may not be changed in any way.
Robotic Mower
The following text should be put on the outside of the mower device:
(Translation: “This equipment contains specified radio equipment that has been certified to the Technical Regulation Conformity Certification under the Radio Law.”)

Manual
The user manual shall be in English or Japanese language and shall include instructions required for the user. In case of module approval, installation descriptions shall be available. In the case with Bluetooth functionality, the module is always installed from the factory, thus the installation description needed is manufacturing description (manufacturing plans, drawings, instructions, test specifications, approval steps, etc. as required by the quality process) together with Implementation Instruction (this document).
Reference of the Japanese approval should be given, indicating the rule by which conformity has been approved, i.e. the following text shall be in the manual which covers Bluetooth specific instructions:
This robotic mower device contains an internal module which is approved for use in Japan according to:
Japanese Radio Law Compliance.
This device is granted pursuant to the Japanese Radio Law
This device should not be modified (otherwise the granted designation number will become invalid).
The certification label cannot be recognized from outside of the mower since it is installed inside the host (robotic mower device) and the mark is also too big to fit on the HQ-BLE-1 module. Therefore the following information must be referenced in the user manual:

  • The MiC-mark is defined as below,
  • boxed R, and
  • certificate number.

For the Bluetooth module, the boxed R shall be followed by 202 and a certification the specific number, which gives R 202-SMG024 as follows:
