Declaration of Operating Channel Limitation for CMU Device

Declaration Channel Limitation

This document serves as a declaration regarding the operating channel limitations for the Cell Monitoring Unit (CMU) device. Manufactured by Jiangsu Toppower Automotive Electronics Co., Ltd., and certified by PHOENIX TESTLAB GmbH, this device is designed with specific constraints to comply with regulatory requirements.

The CMU, identified by FCC ID 2BNQR-CMU, operates in 802.11 b/g/n mode. However, for devices marketed in the US and Canada, the firmware is intentionally limited to channels 1 through 11, spanning the frequency range of 2412 to 2462 MHz. This limitation ensures adherence to regional regulations and prevents the end-user from selecting any other operating channels outside of this specified range.

This declaration clarifies that the end-user has no ability to modify or circumvent this firmware-imposed restriction. Any inquiries regarding this limitation or the device's functionality are welcome and should be directed to the contact information provided.
