Operation

Preset Tuning
Up to 30 stations may be stored in the
AVR40’s memory for easy recall using the
front panel controls or the remote.

To enter a station to the memory, first
tune the station using the steps outlined
above. Then:

1. Press the 

button 

Ó

on the

front panel. Note that the 

MEM

indicator

will illuminate and flash in the informa-
tion display.

2. Within five seconds, press the

Ô

corresponding to

the location where you wish to store this
station’s frequency. To enter a station to
memory location “30,” press only the 

button.

3. Repeat the process after tuning any
additional stations to be preset.

Recalling Preset Stations
• To manually select a station previously
entered in the preset memory, press the

Ô

corresponding to

the desired station’s location. To select
the station in location “30,” press the 

button only.

• To manually tune through the list of
stored preset stations one by one, press
the 

‹ ›

buttons

e

on the remote.

• To automatically scan through the
stations entered in the preset memory,
press the 

button 

33

on the

front panel or 

button 

p

on the

remote. The tuner will run through the
list of preset stations, stopping for five
seconds at each one. Press the 

or 

button again to stop the scan at

your desired station.

In normal operation, the audio or video
source selected for listening through the
AVR40 is sent to the record outputs. This
means that any program you are watch-
ing or listening to may be recorded sim-
ply by placing machines connected to the
outputs for 

§

, 

¢

or

ª

in the record mode.

When a tape recorder with separate
record and playback heads is used, you
may monitor the output of the recording
by selecting the 

input

8d

. Note that the word 

MONITOR

will briefly appear in the front panel dis-
play to remind you that you are listening
to the record playback instead of the
actual input source being recorded. After
three seconds the display will once again
display the selected input source, but the
red 

TAPE M

indicator will remain illu-

minated to remind you that you are lis-
tening to the record playback rather than
the direct input source.

Special circuits in the AVR40 make it pos-
sible to copy the program from one video
source to another while you are listening
to a separate and different input. When
making a video dub note that the VCR
connected to 

ª

will always be

the record machine, and the playback
source will be either the equipment con-
nected to the 

input 

¶

or the

front panel 

%

.

To make a video copy, simply press the
front panel 

button

˘34

corresponding to the video source

being played back. It is not necessary to
press the 

buttons when

making a direct video dub. The
information display will briefly show 

VID2 > 1

or 

VID3 > 1

to confirm

the dubbing operation. After the display
returns to show the current input source
for the main system, a red indicator will
illuminate inside the 

button to remind you that a Video Dub is
in process.
