Table 6 General Characteristics
Note 1: The frequency range needs to be restricted to 915 to 924 MHz (channels 6-10) to meet
Australian/New Zealand standards.
Note 2:Due to the band pass filter, receiver sensitivity is reduced by approximately 1dB on channels 1,
2, 8, 9, and 10 (906MHz, 908MHz, 920MHz, 922MHz, and 924MHz). This improves receiver
performance in the presence of interferers on channels 3, 4, 5, 6, and 7 (910MHz, 912MHz,
914MHz, 916MHz, and 918MHz).
