The LCD (Liquid Crystal Display) presents a great deal of setup
and operating information clearly and conveniently. (See Figure

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 pr
ess the Mode/Set button
once. The wor
d
“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 desir
ed. When finished with any changes, use
the ar
r
ow buttons to move to
“QUIT”. Pr

button
once to exit the menu and return the receiver to
nor
mal operation. (
“RF” and “AF” will r

window, indicating the return to normal receiver operation,
with the receiver’s audio output again enabled.)
