Note :
Measurement made using a PO WER_TABLE entery of TX_PRE 80, INT PA63, EXT PA255. This ensures that the
Bluetooth requirements for ACP and those defined by the FCC and ETSI are satisfied over the operating
temp erature rang of -5Ð to + 45Ð . Although the design is capable of generating in excess of + 18dBm,
regulatory compliance over the full temperature range of -5Ð to + 45Ð will not be satisfied if the transmit power
approaches this value.
