Rear Panel Controls and Functions (Fig. C)
8. ANTENNA INPUT JACK: BNC-type antenna connector for Tuner "B." Attach the
antenna directly, or extend it with a low-loss antenna cable. See the "Antennas"
section on page 5 for more details.

(12) from ground. Normally, the switch should be to the left (ground connected). If
hum caused by a ground loop occurs, slide switch to the right (ground lifted).
12. BALANCED AUDIO OUTPUT JACK: XLRM-type connector. A standard 2-conductor
shielded cable can be used to connect the receiver output to a balanced micro
phone-level input on a mixer or integrated amplifier.
13. UNBALANCED AUDIO OUTPUT JACK: 1/4" phone jack. Can be connected to an
unbalanced aux-level input of a mixer, guitar amp or tape recorder.
14. POWER INPUT JACK: Connect the DC plug from the included in-line AC adapter.
15. CORD HOOK: Loop the small DC cord around the cord hook to keep the DC plug
from pulling out accidentally.

E Band Frequency Scan Group Selection
To select frequency Scan Group G1 Germany, G2 France or G3 Nordic (example page
16). With the power off, Press and hold upper arrow key while powering on. Select the
required Frequency Scan Group G1, G2 or G3 by pressing the "Mode/Set Button" until
the desired group appears in the display.To store the selected frequency Scan Group,
press the power switch to turn the receiver OFF, then press the power switch to turn the
power on.
How to Restore Default Settings
To return all the receiver functions to their original factory-default settings, first turn the
receiver off. Then hold in the Mode/Set button while pressing the Power switch. The
LCD will briefly show "RESET" , followed by "WAIT" (release the Mode/Set button),
before commencing normal-mode operation at the default settings.
High-pass Filter
Internal high-pass filter circuitry may be set to four positions: High-pass Off, or a 6 dB,
12 dB or 18 dB slope at 150 Hz. The default setting is Off ("HP OFF"). Increasing the
slope of the high-pass filter further suppresses unwanted low frequencies, while
maintaining the frequency response in the desired audio range.

From the normal operating mode, press the Mode/Set button once to enter the
Function Menu mode. (Only the frequency will remain in the LCD window, and the
receiver's audio output will be cut off.)
Use the Up/Down arrow buttons to reach the desired function. The value in the
LCD window is the current setting for that function.
Press the Mode/Set button once again to open the list of available choices for that
function. The value will flash, indicating that it can be changed (Edit mode).
Use the arrow buttons to go through the available choices, stopping on the desired
new choice.
(a) To accept and enter the new choice, press and hold the Mode/Set button until
"STORED" appears in the LCD. This changes the value and puts the function of the
buttons back at Menu level (step 2 above). (The "B" tuner light will come on while
the Mode/Set button is depressed, to confirm its action.)
(b) To "back out" of the Edit mode without making a new choice, simply press the
.
Mode/Set button once The word "ESCAPE" will appear in the window and the
function of the buttons will revert to the Menu level (step 2 above), without making
any changes.
Repeat this selection process for any other function changes desired. When
finished with any changes, use the arrow buttons to move to "QUIT". Press the
Mode/Set button once to exit the menu and return the receiver to normal
operation. ( "RF" and "AF" will reappear in the window, indicating the return to
normal receiver operation, with the receiver's audio output again enabled.)
When the receiver is in the Menu or Edit mode, its audio output is silenced. Once
control-setting operations are completed (or Escape is used), normal receiver
operation will resume with its audio output restored.
While in the Edit mode, if no action is taken for approximately 30 seconds (no
buttons pressed), the receiver will "back out" to the Menu mode. Similarly, after
about 30 seconds of inaction in the Menu mode, the receiver will "back out" to
normal receiver operation with audio output restored.
