Consult Table 3 for the applicable power settings. The LN700 is a multi-modem system operating between 757-
758MHz and 787-788MHz, in channel bandwidths of 6.25kHz, 12.5kHz, 25.0kHz and 50kHz. Modulation choices in
each bandwidth include QPSK, 16QAM, and 64QAM. OTA Rate and maximum power is based on the modem
choice and the applicable emission mask for the operating frequency.

Consult Table 4 for the applicable Frequency limit band edge settings. TX and RX frequencies may be set with
6.25KHz resolution, subject to the Guard Band A and B block\band edge compliance limits. The compliance limits
are enforced by the Operational Frequency Limit table below.
