CARE AND MAINTENANCE
To record on a tape in which the tab has been
broken, place a piece of adhesive tape over that
area.
On the back of the cassette, there is an erase
prevention tab on each side. To prevent
accidental erasing, break our these tabs with
a screwdriver. If only one side of the tape is to
be protected, break out the tab on the left side
with the side desired facing you.
NOTE: When a tab is broken out, the record
button cannot be depressed.
SAFEGUARD AGAINST ACCIDENTAL ERASURE
When a new recording is made, any problem
material previously recorded is automatically
erased and only the new recording remains. To
safeguard valuable recordings from being erased
accidentally, the cassette and the deck are
equipped with a special device,
Tab for side 1
Tab for side 2
Tab Break out the tab
Cover with tape
CASSETTE TAPE RECOMMENDATIONS
Standard tape lengths have 15 (C-30), 30 (C-60) and 45 (C-90) minutes of recording time on each side.
Longer length tapes of 60 (C-120) minutes of recording time in each side are not recommended. Use
only high quality tapes. If a problem develops, check the unit first with another cassette to determine if
the problem is with the cassette, and not with the unit.
If there is any stack in the tape in the cassette, it should be removed before inserting the cassette. Place
a pencil in one of the hubs and rotate toward the outside of the cassette until all stack is taken up.
MAKING A TAPE RECORDING
The tape recorder in this system allows you to make direct recordings from the radio or CD player to a
blank cassette in the tape compartment. An automatic recording volume level control (ALC) circuit will
automatically control the volume level of your recordings to prevent distortion. You may change the settings
of the volume during a tape recording, as these controls have no effect on the material being recorded onto
the tape.
To make a tape recording, proceed as follows:
Select the function you wish to
record, either radio or CD, and
operate that function according
to its own instructions.
Emptiest reel
Open the cassette Door and
insert a good quality blank
cassette tape into the slots on
the door, with the open end facing
up and the full reel on the right-
hand side. Close the Cassette
Door.
When you are ready to begin
recording, press the cassette
Record ( )Button. The cassette
Play ( ) Button will also engage.
The tapes will begin moving and
all of the material from your
selected source will be recorded
on the tape.

Dynamic Bass Boost System (DBBS)
This special circuit provides bass response, especially at lower volume levels
where the bass has a tendency to disappear. Set the DBBS button to On
to increase the bass. Set the DBBS button to Off for normal bass response.
Note: If you have the DBBS circuit On at high volume and you are listening to
music that contains very strong bass, you may experience some distortion. If
this occurs, reduce the volume or switch the DBBS button Off.
If you wish to listen to your
recording immediately, press the
cassette Rewind ( )Button until
the tape rewinds to the beginning,
then press the Stop/Eject ( )
Button . Set the Function
Switch to the TAPE position and
press the cassette Play ( )
Button to begin playback.

press the Stop/Eject ( )
Button to stop the tapes.

material, such as radio

( ) Button to stop the recording
temporarily. Release the Pause
