Setting Up the Satellite Dish,
Adjusting the Satellite position using Signal Tones
Dish alignment can be done using the audible signal adjustment tone. The
characteristics of the signal tone are shown in the table below. Align the dish to
achieve signal lock and then best signal quality.
Note: The signal adjustment tone automatically outputs as PCM audio type only,
regardless of the Digital Audio Preference set in Audio Setup.
Provided the RF cable is connected between the satellite receiver and the LNB,
Signal level displays a low number (typically less than 40). As the receiver achieves
Signal Lock, the Signal Level increases, and the tone changes from a slow repeating
beep to a steady tone. Once Signal Lock is obtained, align the dish to increase the
Signal Quality to the best possible value (up to a maximum of 10).
Signal Level and Signal Quality
The Signal Level and Signal Quality of the incoming signal are displayed both
numerically and graphically using bar graphs.
The Signal Level is associated with the RF input signal level. The Signal Level
display is continuously updated to indicate the relative strength of the received RF
input signal. It is displayed in the range from 0 to 100. Signal Level is displayed on
the Tuning / Preset and Dish Setup menus both numerically and graphically.
The Signal Quality (displayed in the range from 0 to 100) is associated with the Bit
Error Rate, and is a measure of the signal quality. Signal Quality is displayed both
numerically and graphically on the Dish Setup menu. To obtain the best signal
quality, adjust the dish position to obtain the highest Signal level and Signal
Quality possible.
Temporary, solar-related electromagnetic disturbances occur every year during the
spring and autumn months. These disturbances usually persist for several minutes
a day for approximately one week at this time. Your service provider can advise
you about channels that may be adversely affected.
To verify your satellite LNB antenna installation or improve signal reception, refer
to your antenna equipment installation manual, or contact your local service
provider.
