LIST
The IF Bandwidth selection list is created in the IF Bandwidth Select menu
of the Configuration menu. Once in this menu, the desired selection list
can be created to tailor the bandwidth selections for a specific installation
or application. Creation of the IF Bandwidth selection list is performed as
follows:
1.
Press the MENU key as required to display the IF BW Select menu,
as follows:
1.IF BW SELECT
0.2
INCLUDE
2.
Rotate the EDIT knob to step through the IF bandwidth list. At each
step, the IF bandwidth is displayed with the word “INCLUDE” or
“SKIP” to its immediate right.
3.
Pressing the IF BW control key toggles the Include/Skip status, and
then increments to the next higher available bandwidth. If the status
was INCLUDE, pressing the IF BW key changes the status to SKIP.
Rotation of the EDIT knob moves to the next bandwidth in the list
without changing the bandwidth status.
4.
Continue through the bandwidth list until the selection list is

selections with SKIP next to the value are excluded from the list.
5.
When the selection list is completed, press the DET key to exit the
Configuration menu.
3.3.5 GAIN CONTROL MODE SELECTION
There are three gain control modes that are available for selection: AGC
FAST, AGC SLOW, and MANUAL. In either of the AGC modes, the
receiver automatically adjusts its gain level to accommodate varying signal
strength levels. AGC provides a minimum of 90 dB of gain control range.
In the Manual gain control mode, the receiver gain is manually set by
entering an attenuation value ranging from a minimum of 0 dB to a
maximum of 100 dB. (The gain control range is specified to a minimum
of 90 dB.) The type of gain control is selected by pressing the AGC key.
When the AGC key is pressed, the LED on the key lights, and the AGC
field of the parameter display flashes with the currently selected gain
control mode. Each press of the AGC key steps through the gain control
selections. Rotation of the EDIT knob can also be used to select the gain
mode. When the Manual gain mode is selected, a three-digit number
representing the last entered attenuation level, flashes all three digits. If
the AGC key is pressed again, only the least significant digit flashes. With
the single digit flashing the EDIT knob allows setting the attenuation in
1 dB increments. Entering a value at the keypad, in the 0 to 100 range, and
