1. ANTI-THEFT
The BMW anti-theft radio circuitry is designed to essentially render your radio unsaleable if it is stolen. If the radio is subse-
quently electrically reconnected, it will not operate until afive-digit security code assigned to your radio is entered. The anti-theft
features and operation are as follows:
1. After the ignition key is removed, the red “anti-theft” LED will continuously flash, drawing attention to this feature.
2. Should anyone, such as a thief, touch any pushbutton on the radio after the key is removed, the anti-theft Inscription will
flash and awarning tone will sound for 5minutes or until the ignition is turned on.
3. If the voltage supplied to the radio drops below apreset value due to aweakened battery, repair work, or removal of the radio
(by athief), the radio will be inoperative once voltage is restored. This condition will be indicated by the word “code” being
shown on the display.
4. The proper 5digit code shown on the TWO CARDS SUPPLIED TO YOU must then be entered (using the proper number
radio pushbutton selectors) when the radio Is on and the display shows “code”. If the correct code is not entered In three suc-
cessive tries, the radio will not accept entry until the radio has been left on for one hour with the ignition on.
IMPORTANT: When entering the 5digit code number, be sure to complete sequence numbering of that 5digit code. For
example: Code No. sequence Is 43215 and you mistakenly enter 42 Instead of 43,continue the code number sequence of
215 to complete that entry. In this case, a“beep” will sound to signal input of the 5-dlgit code, the word “code” will remain on
the display, and the radio will not operate. Re-enter the correct number sequence of 43215 and operation of the radio will
continue. The likelihood of guessing the correct code is extremely remote. The radio Is, therefore, unsaleable to athief.
NOTE: If an audible beep is heard while entering the 5-dlgit code, STOP immediately! Begin entering the code again, start-
ing with the first number of the 5-diglt code.
5. The code card should be placed in your wallet, or with the vehicle title papers for security as deemed necessary by your indi-
vidual needs. Do not leave your code cards in vehicle.
6. Should radio or electrical repairs become necessary, please give the repairing facility the radio code number. If you donot,
only authorized BMW dealer personnel can obtain the code from BMW.
7. Should you lose your code cards, contact the nearest BMW dealer who will then obtain your code from BMW. You ma/ be
charged for removal of the radio to ascertain the radio chassis number.
8. WARNING: FOR YOUR PROTECTION, CODES WILL NOT BE GIVEN OUTTO ANYONE UNDER ANY CIRCUMSTANC ES
OTHER THAN AUTHORIZED BMW DEALER PERSONNEL AFTER PROOF OF VEHICLE OWNERSHIP AND PROPER
IDENTIFICATION IS ESTABLISHED.

KE-BIZBM-O:
1. CASSETTE OPERATION
To use the cassette, the radio must be in “ON” position.
Inserting atape cassette automatically switches the unit
and dual function controls from the radio to the tape mode.
2. LOGIC CONTROL
This radio utilizes logic circuitry that automatically deter-
mines the correct direction for fast forward and rewind. A
standard cassette has two sides that are played in either
direction. When acassette is playing, the top side will be
indicated on the display as program “SIDE 1the bottom
side will be program “SIDE 2”.
3. FAST FORWARD/REWIND
TAPE SEEK
The fast forward/rewind lever employs 2-step operation.
Raising the lever one step is used for fast forward, while
lowering the lever one step is used for fast rewind. Fast
forward/rewind can be cancelled by raising or lowering
the lever again one step. Raising or lowering the fast for-
ward/rewind lever two steps (as far as It will go) activates
the tape seek operation. “SEEK” will appear on the Liquid
Crystal Display. Raising the lever automatically moves the
tape to the next selection on the tape for playback. Lower-
ing the lever returns the tape to the beginning of the cur-
rent selection for playback.
Tape “SEEK” will only function If four seconds of silence
exist between selections. However, excessive record
player stylus noise, due to dust or scratches on the record
on home-recorded tapes may interfere with these func-
tions.
The cassette automatically ejects from the unit if tape
setting operations cannot be completed within afew sec-
onds. This may be caused by afaulty or damaged cas-
sette. Determine the cause of the problem or use a
different cassette.
4. PROGRAM
Press the volume knob to reverse the current direction of
tape transport. The tape will automatically reverse when
the end of either side is reached.
5. DOLBY NOISE REDUCTION
Dolby Noise Reduction reduces the level of “tape hiss”
inherent in cassettes by “encoding” the tape. Use of the
Dolby NR function with non-Dolby NR tapes will decrease
high frequency response. By not using the Dolby NR func-
tion with Dolby NR encoded tapes, the high frequency
response will be intensified. The symbol “”will appear
on the display when the Dolby NR button is pressed.
6. TAPE EJECT (T1I\
Press the eject (EJ) button to eject tape cassette and
return to the radio mode.
7. AUTOMATIC EQUALIZATION
The playback equalization of NORMALtapes differs from
CHROME (CrOg), and METAL tapes. When ahigh biased
tape (including metal) Is Inserted, the unit will automati-
cally change to the correct equalization level and “MTL”
will be Indicated on the liquid crystal display.
8. SKIP BLANK (SB) (Tli)
The skip blank function causes the unit to automatically
advance the tape to the next recorded portion when a
blank section of tape exceeds approximately 12 seconds.
When along unrecorded portion Is detected at the end of a
tape, the unit advances the tape to the end and then
switches to the other side of the tape. The indicator “SB”
appears on the display when the skip blank (SB) button is
pressed. Additionally “SEEK” will be displayed while the
tape is automatically advanced during skip blank opera-
tion.
9. IGNITION “KEY OFF” PAUSE
When the ignition is turned off while atape is playing, the
cartridge will automatically enter the pause mode (pinch
roller release). When the ignition Is turned on the unit will
return to the normal play mode. When the unit is in the
pause mode it will not accept another cassette.
10.
AUTOMATIC TAPE SLACK CANCELLER (ATSC)
The automatic tape slack canceller removes any slack in
the cassette tape before play to protect and extend the life
of your tapes.
11. ROTATING TAPE HEAD
The rotating tape head in your tape cassette player
ensures accurate horizontal tape alignment in both direc-
tions for optimum sound level reproduction and frequency
response.
NOTE:
Your BMW ANTI-THEFT Radio contains afull logic computer
controlled 3-motor drive which controls the automatic ^pe
slack canceller (ATSC) and rotating tape head mechanism.
During cassette tape loading/unloading or tape transport
directional changes the operation of the motor drive ernits an
audible “precision like” mechanical sound which indicates
normal tape cassette player operation.

WITH LED INDICATION
1. AM/FM/WB (Weather Band)
Pressing the [)button causes “AM”, “FM” or “WB” to
appear on the display. The currently tuned frequency is
also displayed when AM or FM is selected. “WB” indicates
that the WB band is selected, and aweather broadcast
frequency is automatically tuned without display of the
frequency. A“beep” sounds if there are no weather band
broadcasts available for reception. Manual tuning and
seek tuning operations using the tuning lever can be
employed to change to afrequency other than the one
automatically tuned.
2. MANUAL/SEEK TUNING
The tuning lever employs 2-step operation. Raising or
lowering the lever one step is used for manual tuning.
Raising the lever increases the frequency, while lowering
the lever decreases the frequency. Raising or lowering
the tuning lever two steps (as far as it will go) activates the
seek tuning operation. Raising the lever automatically
tunes and locks onto the next higher receivable broad-
cast frequency, while lowering the lever tunes and locks
onto the next lower receivable broadcast frequency.
3. SCAN TUNING
When the (on/off) volume control knob Is pressed, scann-
ing begins upscale from station to station, pausing seven
seconds at each medium to strong frequency. Scanning
stops when the volume knob is pressed again during the
seven second pause.
4. STEREO
When astereo station is received, the “ST” indicator will
light up on the display. It will flash when the signal strength
diminishes.
5. AUTOMATIC LOCAL/
DISTANCE SWITCHING
New electronic circuitry automatically selects the local or
distance mode for the best reception and eliminates the
need for manual switching.
6. FM RECEPTION
FM reception will occasionally exhibit hissing and flutter-
ing noises due to signal reflections or blockage by hills or
tall buildings. FM signals strength diminishes rapidly after
approximately 25 miles from the transmitter.
7. PROGRAMMING OR RE-PROGRAMMING
PRESET RADIO STATIONS
A. Tune in the desired radio station.
B. Push the desired preset station selection for 1.5 sec-
onds and an audible “beep” will sound indicating that
the frequency has been memorized.
C. Repeat this procedure for the remaining preset station
selectors on both the AM and FM bands.
8. PRESET STATION INDICATORS
Each of the preset buttons has Its own built-in LED.
Pressing apreset button causes the color of the corre-
sponding LED to change from orange to green to indicate
selection of that preset frequency.
NOTE;
The radio programming controls have dual functions. Each
button can be set to one AM and one FM station.
