Power On/Off
To turn the receiver on, press in the Power switch. The Alert
light and the LCD window will come on (about 1-2 seconds).
The operating frequency will be displayed in the window after
the power-up sequence. To turn the receiver off, press the
Power switch again.
LCD Window
The LCD (Liquid Crystal Display) presents a great deal of setup
and operating information clearly and conveniently. (See Figure
D for examples.)
Up/Down Arrow Buttons
In conjunction with the Mode/Set button, the arrow buttons 
permit moving through the menu of functions, and choice of
settings within each function.
Mode/Set Button
The Mode/Set button shifts the receiver from normal operation
into Menu mode and, in conjunction with the Up/Down arrow
buttons, permits selection of different features and changing of
their stored values in the Edit mode.
How to Make Setting Changes
1.
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.)
2.
Use the Up/Down arrow buttons to reach the desired 
function. The value in the LCD window is the current 
setting for that function.
3.
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).
4.
Use the arrow buttons to go through the available choices, 
stopping on the desired new choice.
5.
(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.
6.
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.)
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.
