This document is a declaration from VTech Telecommunications Ltd regarding the Bluetooth Low Energy (BLE) functionality of their DECT 6.0 cordless phone. The declaration states that the RF chip, model BK3296QN202, installed in the DECT 6.0 cordless phone (Base) supports BDR (GFSK), EDR (π/4-DQPSK, 8DPSK) and BLE functions. The FCC ID for the device is EW780-3612-00, and the models covered by this declaration include EL1121-2, EL1121, EL1121-3, EL1121-4, EL1121-5, EL1121-11, EL1121-21, EL1121-31, EL1121-41, EL1121-51, and EL1121-XY.
The key point of the declaration is that for use in America, the BLE functionality of this chip will not be supported or enabled. VTech has shielded the BLE functionality through software, ensuring that the end user does not have the capability to activate it. This declaration is likely related to regulatory requirements or product specifications for the US market.
