(a) _{BlueCore4-ROM Plug-n-Go firmware keeps RF transmit power within the Bluetooth v2.0+EDR specification limits}
(b) _{Class 2 RF transmit power range, Bluetooth v2.0+EDR specification}
(c) _{Measurement methods are in accordance with the Bluetooth v2.0 + EDR RF Test Specification}
(d) _{Modulation accuracy utilises differential error vector magnitude (DEVM) with tracking of the carrier frequency drift.}
(e) _{The Bluetooth specification values are for 8DPSK modulation (values for the π/4 DQPSK modulation are less stringent)}
