Selecting the Frequency Range

Frequency Band LED begins to flash.
2. Use the Set button to click through the five
bands of frequency range options.

RF Power Overload
When the Overload Antenna Indicator displays a red LED, it indicates
that a strong RF signal is overloading the antenna amplifier. To correct an
overload condition, increase the distance between the antenna and trans-
mitter, or lower the antenna gain setting.
Warning: Overloading the antenna amplifier results in reduced channel
count and poor system performance.
