Information about the strength and quality of the incoming signal obtained via
your satellite LNB antenna (dish) installation and current receiver setup is available
from the Dish Pointing menu graph display.
To display the Dish Pointing menu
Step 1. Display the Main Menu (see Figure 7).
Step 2. Move to Dish Pointing and press SELECT.
Available options: Move to Exit and press SELECT (or press 1 and then SELECT)
to return to the previous menu.
You can view information about the current setup. Two independent bar graphs
provide continuous display of Signal Strength and Signal Quality. Signal Strength
and Signal Quality information is also displayed numerically at the Receiver Status
and Receiver Setup menus (see “Receiver Status menu” and “Receiver Setup
menu”).

Your Business Satellite Receiver actively monitors and updates the strength and
quality characteristics of the incoming signal as it is decoded, and displays this
information dynamically using two (2) bar graphs. The Signal Strength (displayed
on a scale from 0 through 99) is associated with the Symbol Rate and signal input
level. The Signal Quality (displayed on a scale from 0 through 9) is associated with
the Bit Error Rate, and is a measure of how much of the original signal information
is being received.
Certain receiver settings can cause signal loss or degradation which can compro-
mise video or audio information, or data. The effect of any changes you make to
your satellite LNB antenna installation is immediately displayed on the bar graphs.
Signal Strength and Signal Quality can also be affected by changes at the signal
source, and/or by adverse environmental or terrestrial conditions. Taken in com-
bination, certain receiver settings and signal conditions can cause the Signal
Strength and Signal Quality (values) to increase or decrease accordingly.
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 during these periods. Your service provider will
advise you about channels that may be adversely affected. For troubleshooting
information, see “Appendix B Troubleshooting”.
To verify your satellite LNB antenna installation or improve signal reception, refer
to your antenna equipment installation manual, or contact your dealer or service
provider.
