Press the soft key labeled "SENS." (for sensitivity) to bring
up the choices available for adjusting the Advantage s
receiver sensitivity. Press the button labeled "AUTO" so that
the word AUTO is shown in reverse video (white letters on a
black background) if you would like the Advantage to
automatically adjust its sensitivity for changing conditions.
When in the AUTO sensitivity mode, the Advantage
automatically adjusts both the 200 kHz and 50 kHz receiver
sensitivities for good picture quality.
To manually adjust the sensitivity when the display is
showing only one frequency (200 or 50 kHz), press the button
labeled"Sens.+" or "- Sens" ( or simply rotate the large front
panel knob) to increase or decrease the receiver gain. Note
that the soft key shows a number which indicates the relative
sensitivity being used (+1 to +32).
To manually adjust the sensitivity when the display is
showing both frequencies (200 kHz and 50 kHz), notice
which way the arrow within the Sensitivity softkey is pointed
(see examples at right). If pointed to the right, the knob can
be used to adjust the sensitivity of the right side of the display
and if pointed to the left, you can use the knob to adjust the
sensitivity of the frequency shown on the left of the display.
Press the softkey under the right or left side of the sensitivity
soft key to move the selection arrow from right to left.
When you choose to manually adjust the sensitivity, the
Advantage turns off the AUTO sensitivity mode and it will
remain off until the AUTO soft key is again selected. Note:
when AUTO mode is turned on, the word AUTO will be
displayed in reverse video (white letters on a black
background). To exit the sensitivity menu and save your
adjustments, simply press the soft key labeled "LAST" to
