The Main Menu Options
When the receiver‟s front panel is not being used, the idle screen featuring the X-Digital
Systems logo will be displayed
1
. There are two important statistics displayed on this front
logo screen: EB,
energy per bit relative to noise floor
, which is a quantitative measure of
signal quality; and AG,
automatic gain
, which is an indicator of the signal level. Both of
these quantities serve to describe the quality of the satellite signal and should be used as a
guide when positioning the satellite dish. Better signals have better separation between
the data and noise floor, and thus a higher EB. EB range is 0 - 18. The receiver will fade
in and out below 5 dB Eb / No, and loose lock completely at around 3.5 dB. A powerful
signal will have a high AG (indicating little amplification is required) while a weak signal
will have a low AG (indicating unit is amplifying signal).
Once the ▼ button is pressed, the receiver will navigate into its main menu options:
STATUS, SETUP, and AUDIO PORTS. Continually pressing ◄ (or ►) will cycle
through these three main menus. Pressing ▼ or
SET
will navigate into whichever one of
the three options is currently selected.
From the Main Menu, pressing ◄ or ► will access the Speaker Volume screen and allow
the volume to be increased or decreased. From the Speaker Volume screen, pressing
3
will mute the volume completely and pressing
1
will access the software VU Meter
screen.
