Basic Operation

When manually tuning stations, observe
the 

indicator 

R

and 

the 

indicators 

L

. The more 

bars that are visible on the 

indicator, the stronger the signal

and the better the station will sound. A
station is properly tuned when the

indicator is illuminated.

Tuner Mode
Pressing the

&

or 

r

button on the front panel or remote
selects how a station will be received.
When the button is pressed so that the

indicator

M

is lit, stations broad-

casting in stereo will be received in
stereo. You may note stereo broadcasts by
observing that the

indicator 

K

will illuminate. When the

button

& r

is pressed until the

light 

M

goes out, all stations will be received in a
monaural mode regardless of the method
of transmission.

NOTE: When a station is broadcasting in
stereo, but has a weak signal level, the
reproduction may not be acceptable. In
this case, select the Auto Off mode, as
monaural reception is less susceptible to
noise in weak reception areas.

Tuner Presets
There are thirty preset positions that may
be used to store your favorite stations in
any order. These may be used to memo-
rize the station’s frequency, reception
mode and the station’s name. Stations
may be preset automatically or manually,
and then recalled in a variety of ways.

Automatic Station Preset Selection
This process automatically scans the 
AM and FM bands and enters all stations
with proper signal strength into the
memory. To automatically preset the
tuner’s memory, follow these steps:

1. Select the tuner as the unit’s input by
pressing the 

button 

2d

.

2. Using the 

buttons 

Òs

, select

the first station you wish to preset at the
low end of the AM or FM band.

3. Start the automatic tuning preset by
simultaneously pressing 

and

⁄

on the front panel 

%Ò

. The

station tuned in step #2 will be entered
into the tuner’s memory as 

PRESET 1

.

The 

indicator 

N

will flash. The

display will show increasing frequencies
to indicate that the auto scan is in
progress.

4. Each time the tuner finds a station the
scanning will pause and the station will
be played for five seconds. During this
time you have the following options:

a. To enter the station in the next
open memory position, no action is
needed. After five seconds the tuner
will enter the station and the preset
number will be visible at the far left
side of the main information display.

b. The frequency band may be
changed by pressing the 

button 

2h

.

c. If the tuner is scanning FM
stations, the 

may be changed

from 

to mono by pressing the

button 

&

.

d. If you do not wish to enter the cur-
rent station into the preset memory,
press the 

⁄

button 

Òs

on

the front panel or remote.

5. After the desired action is completed,
or five seconds elapse, the tuner scan will
continue. The operation will stop auto-
matically when all 30 preset positions are
filled or when both frequency bands have

been completely tuned, whichever comes
first. To stop the automatic preset process
at any time press the 

button 

^

or

any input selection button.

Manual Tuner Preset
Stations may be manually entered into
the tuner’s memory in any order. Manual
entry is performed from the remote
control only.

1. Tune to the desired station as outlined
in the Tuner Operation Section. 

2. Press the 

button 

%v

and

note that the 

indicator 

N

will

flash. 

3. While the indicator is flashing for the
next 5 seconds, enter a number from 
1 to 30 using the number buttons on the
remote 

x

. Any number may be used,

but if another station has already been
programmed into the location number
selected, the previous setting will be lost.

a. To enter a single digit memory
location, press 

before the number,

or enter the number and wait a few
seconds.

b. If an invalid number (other than
1–30) is entered, the display will
flash to alert you that the entry 
is invalid and it will return to the
previous frequency display.

4. When the preset memory has been
properly programmed the 

indicator 

N

will stop blinking. 

Station Name Preset
In addition to identifying stations by
their broadcast frequency, each preset
station may be assigned a name using
alphanumeric characters. This enables
you to identify a station by its call 
letters, program format, or any other 
five character phrase.
