1. PROTECT YOUR RADIO FROM THEFT
Your BMW radio will not operate once it is removed
from the console, making it virtually useless to a
thief. The only way to restore power to the radio once
it is removed is to enter afive-digit security code
unique to your radio. The anti-theft features of your
radio operate as follows:
1.When the ignition key is removed, the red anti-
theft LED indicator will flash continuously.
2. If any buttons on the radio are touched after the
key is removed, awarning tone will sound for five
minutes or until the ignition is turned on. The anti-
theft indicator will also flash.
3. Adead battery, electrical repairs, radio removal
or reduction of voltage supply to less than apreset
value will render the radio inoperable until voltage
is restored and the security code is entered. The
radio must be turned on. before the code is en-
tered. The word “code” will show on the display.
4. To enter your security code, which can be found
on the two cards supplied to you by BMW, turn
the radio on and use the appropriately numbered
radio push-button selectors.
If the correct code is not entered in three succes-
sive tries, the radio will not accept another entry
until it has been left on for one hour.
5. Do not leave the code cards in your car. Place
them in your wallet or with your vehicle title papers
for security, if you lose the code cards, contact
the nearest BMW dealer. He will get your code
from BMW. There may be acharge for removing
the radio to ascertain its chassis number.
6. If radio or electrical repairs become necessary,
please give the repair facility your radio code num-
ber. If you do not, only authorized BMW person-
nel can obtain the code from BMW.
Important: If you make amistake in entering your
code, complete the entire sequence before en-
tering the correct code. For example, if your code
is 12345, and you mistakenly enter 125, finish the
five-digit sequence (45) to complete that entry. The
radio will not operate, and the word'“code” will
again appear on the display. Enter the correct
code at this time.
Exception: If you hear abeep when entering your
code, stop immediately! Begin entering the code
again, starting with the first digit.
WARNING: FOR YOUR PROTECTION, CODES
WILL NOT BE GIVEN OUT TO ANYONE-
UNDER ANY CIRCUMSTANCES—EXCEPT
AUTHORIZED BMW DEALER PERSONNEL
AFTER PROOF OF VEHICLE OWNERSHIP AND
PROPER IDENTIFICATION IS ESTABLISHED.

AM/FM
Press the BAND button and AM or FM will appear
on the display indicating which band is being
received. When AM or FM is chosen, the currently
tuned frequency is also displayed. Press the button
to change from band to band.
WEATHER BAND(WB) AUTOMATIC FREQUEN-
CY SELECTION
When the WB button is pressed, regardless of what
source you are currently listening to, weather band
seek tuning begins automatically and finds the stron-
gest broadcast frequency. If the broadcast frequency
in your area is too weak, or nonexistent, abeep will
sound after the WB frequencies have been run
through three times. If you press the WB button
again, the radio returns to the previous source.
AUTOMATIC LOCAL/DISTANCE SWITCHING
New electronic circuitry automatically selects the
local/distance mode for best reception, eliminating
the need for manual switching.
MANUAL/SEEK TUNING
The TUNING LEVER is used for both manual and
seek tuning. For manual tuning, raise or lower the
lever one step—up for higher frequencies, down for
lower frequencies. For seek tuning, raise or lower
the lever as far as it will go. The unit will automati-
cally tune and lock onto the next higher or lower
receivable broadcast frequency.
STEREO
The ST indicator will light up on the display whenever
astereo station is received. The indicator will flash
when signal strength diminishes.
PRESET STATION INDICATORS WITH LED
Each PRESET button has abuilt-in LED. When a
PRESET button is pushed, the LED will change from
orange to green, indicating selection of that preset
frequency.

SCAN TUNING
Signal scan tuning allows you to tune into each
medium-to-strong frequency pausing seven seconds
at each. Push the ON/OFF button once to begin tun-
ing up scale, and press it again during apause to
stop the scanning.
FM RECEPTION
Signal reflections or blockages caused by hills or tall
buildings may cause hissing and fluttering noises in
FM reception. FM signal strength diminishes beyond
25 miles from the transmitter.
PROGRAMMING/REPROGRAMMING PRESET
STATIONS
Tune in the desired radio station. Then push a
PRESET selection button for 1.5 seconds. When you
hear abeep, the frequency has been memorized.
Repeat this procedure for the remaining preset sta-
tion selectors on the AM and FM bands.
NOTE: The radio programming controls have dual
functions. Each button can be set to one AM and one
FM station.
BASS, TREBLE, FADER AND BALANCE CONTROL
Each time the MODE button is pressed, control of
bass, treble, fader, or balance is selected in turn.
The selected mode is shown on the display and can
be adjusted by the +and —buttons. About five
seconds after adjustment, the display returns to its
previous state.
When the MODE button is pressed continuously for
more than 1.5 seconds, the level of each mode
returns to flat or center. At this time abeep is sound-
ed and “FLAT” is displayed on the display.

CASSETTE OPERATION
To use the cassette player, turn the radio on. When
acassette is inserted, the unit will switch automati-
cally from radio to tape mode.
FAST FORWARD/REWIND
The FF/RW lever has a two-step operation. Raise the
lever one step to fast forward; lower it one step to
rewind. Repeat the same action to stop the appropri-
ate function. The logic circuitry in your radio will au-
tomatically determine the right direction for fast
forward or rewind.
Astandard cassette has two sides and can be played
in either direction. When in play, the top side of a
cassette will be indicated as “1 ”on the display. The
bottom side will appear as “2”.
TAPE SEEK
Raising or lowering the fast forward/rewind (FF/RW)
lever two steps (as far as it can go) activates the
seek mode. SEEK will appear on the display. To
move to the next selection on your tape, raise the
lever as far as it can gc. The tape will move rapidly
to the next selection, to restart the current selec-
tion, lower the lever in the same fashion.
TAPE EJECT (4 EJ)
Press the EJECT button—4 EJ to eject tape cassette
and return to the radio mode.
SKIP BLANK (5 SB)
The SKIP BLANK button—5SB—automatically ad-
vances the tape to the next recorded portion when
ablank section of tape exceeds approximately 12
seconds. When there is along, unrecorded portion
at the end of the tape, the unit advances the tape
to the end and then starts to play the other side.
When the SKIP BLANK button is pushed, SB will ap-
pear on the display. Additionally, SEEK will be dis-
played while the tape is advancing.
DOLBY® NOISE REDUCTION (6 )
Use the Dolby®* Noise Reduction function—button
6DOi—to reduce the level of hiss on Dolby® encod-
ed cassettes. If you do not use the Dolby® noise-
reduction function with Dolby® encoded tapes, the
high-frequency response will be intensified. If you
do use this function with non-Dolby® tapes, high-
frequency response will be diminished.
*The word “Dolby" and the double-D symbol are registered trademarks
of Dolby Laboratories, Inc.
Tape Seek will only function correctly if there are
four seconds of silence between the selections on
your tape. Excessive noise between selections on
home-recorded tapes may interfere with these
functions.
The cassette automatically ejects from the unit if
tape setting operations cannot be completed within
afew seconds. This may be caused by afaulty or
damaged cassette. Determine the cause of the
problem or use adifferent cassette.
REVERSING TAPE DIRECTION
To reverse tape direction, push the ON/OFF button.
The tape will reverse automatically when aside is
complete.
AUTOMATIC EQUALIZATION
The playback equalization of normal tapes differs
from that of chrome and metal tapes. When ahigh-
bias tape, including metal, is inserted, the unit will
automatically change to the correct equalization lev-
el, and MTL will be indicated on the display.
IGNITION-KEY-OFF PAUSE MODE
If the ignition is turned off while atape is playing,
the unit automatically enters the pause mode. The
unit will return to normal play mode when the igni-
tion is turned on. The unit will not accept another
cassette when it is in the pause mode.
AUTOMATIC TAPE SLACK CANCELLER (ATSC)
The automatic tape slack canceller removes any
slack in the tape before play to protect the tape and
extend its life.
ROTATING TAPE HEAD
The rotating tape head in your tape cassette player
ensures accurate horizontal tape alignment in both
directions for optimum sound level reproduction and
frequency response.
NOTE: The BMW Anti-Theft Radio contains afull-
logic computer-controlled 3-motor drive which con-
trols the automatic tape slack canceller (ATSC) and
rotating tape head mechanism. During cassette tape
loading/unloading or tape transport directional
changes, the motor drive emits aprecision mechani-
cal sound which indicates normal tape cassette play-
er operation.
