AUDIO SYSTEMS 9F – 11
DAEWOO V–121 BL4
GENERAL DESCRIPTION
AND SYSTEM OPERATION
STEREO CASSETTE AM/FM RADIO
There are three audio systems offered. The stereo digital
logic cassette AM/FM radio with electronic tape ejection
is offered in standard and deluxe models. Both models
feature RDS (radio data system) which automatically se-
lects the best station within the chain of RDS stations cur-
rently being listened to. A trunk mounted CD changer is
also available.
AUDIO SCURITY SYSTEM
The audio security system is activated whenever the audio
system circuit is disconnected from the battery. A four–
digit security code must be entered in order for the audio
system to resume functioning. The security code is
stamped on a card located in the vehicle (usually in the
glove box). The following security code entering proce-
dure must be used to deactivate the audio security sys-
tem:
1. After connecting the audio security system to the
battery, ”CODE” will flash on the display.
2. Enter the proper security number into the unit, us-
ing the preset buttons No. 1 through 8.
3. For example, if the security number is ”1234”:
a. Press the preset button No. 1. ”CODE” will
disappear and ”1 – – – ” will appear on the dis-
play.
b. Press the preset button No. 2, and ”12 – – ”
will appear.
c. Press the preset button No. 3, and ”123– ” will
appear.
d. Press the preset button No. 4, and ”1234” will
appear and flash three times.4. The audio system will function and will transfer to
the radio.
If the incorrect security number is entered into the unit,
”Err” will appear followed by ”CODE” and there will be sev-
eral audible beeps. If this happens, repeat the security en-
tering procedure beginning with Step 2.
SPEAKERS
All audio systems use eight speakers, four speakers and
four tweeters mounted in each door.
TAPE PLAYER AND CASSETTE
CARE
The head and the capstan are the two parts of the tape
player that should be cleaned. This service should be per-
formed every 100 hours of cassette operation.
To clean the head and the capstan, use a cotton swab
dipped in rubbing alcohol.
A cassette cleaning kit may also be used to clean the head
and the capstan. Follow the cleaning kit instructions to
clean the tape player.
Do not touch the tape head with magnetized tools. If the
head becomes magnetized, it will degrade cassettes
played in the player. No service is performed on the cas-
settes. The cassette manufacturer handles warranties of
the cassettes. Store cassettes away from extreme heat
and direct sunlight.
COMPACT DISC CARE
Handle discs carefully. Store the discs in protective cases
away from the sun, heat, and dust. If the surface is soiled,
dampen a clean, soft cloth in a solution of mild neutral de-
tergent and wipe the disc clean.

9T1 – 8IREMOTE KEYLESS ENTRY AND ANTI–THEFT SYSTEM
DAEWOO V–121 BL4
GENERAL DESCRIPTION
AND SYSTEM OPERATION
REMOTE KEYLESS ENTRY AND
ANTI–THEFT SYSTEM
The remote keyless entry and anti–theft system can per-
form the following functions:
S Remotely lock and unlock the vehicle doors by
means of a hand–held, high–frequency transmitter.
S Sense intrusion into the vehicle.
S Activate a warning in the event of an intrusion.
S Help the driver find the vehicle in a parking area.
S Automatically re–lock the doors if the door or the
trunk is not opened within 30 seconds after the ve-
hicle has been unlocked by the remote keyless
entry.
S Communicate serial data to a scan tool to help
diagnose system faults.
The remote keyless entry and anti–theft system consists
of the following components:
S Keyless entry and anti–theft control module/receiv-
er.
S Security indicator.
S Trunk open switch (NOTCHBACK).
S Trunk tamper switch (NOTCHBACK).
S Front door tamper switches.
S Door contact switches.
S Central door lock relay.
S Turn signal bulbs.
S Siren.
S Hood open switch.
REMOTE LOCKING AND UNLOCKING
The hand–held transmitter locks and unlocks the vehicle
doors by sending radio waves to the control module/re-
ceiver in the vehicle. The effective range of the transmitter
varies between 5 and 10 meters, (approximately 16 to 32
feet), depending on whether or not objects, such as other
vehicles are blocking the path of the radio waves.
The transmitter has a LOCK button and an UNLOCK but-
ton which only function when the ignition is OFF. Pressing
the UNLOCK button has the following effects:
S The doors are unlocked.
S The turn signal bulbs flash twice.
S The control module is disarmed.
Pressing the LOCK button has the following effects:
S The doors are locked.
S The turn signal bulbs flash once.
S The control module is armed.
The transmitter has a replaceable battery. The battery is
designed to last at least two years before replacement is
necessary.
SECURITY INDICATOR
There is a security indicator on the instrument panel. After
the LOCK button of the transmitter is pressed, the module
is placed in the armed mode, and the security indicator
flashes. The security indicator turns ON for 0.1 second
and OFF for 0.7 second. It then flashes at that frequency
until the control module/receiver is disarmed.
INTRUSION SENSING
The anti–theft function is armed if the transmitter sends
the LOCK message to the control module/receiver when
the ignition is OFF. When the hood, door, or trunk is
opened, the hood open, door contact, or trunk open switch
sends a ”ground” signal to the control module/receiver.
Unless the control module/receiver is disarmed, the siren
will be activated when the ”ground” signal is received from
the trunk open, hood open, or door contact switches.
The following actions disarm the anti–theft system:
S An UNLOCK message is received from the trans-
mitter.
S Key operation is detected by the tamper switches.
(The tamper switches are operated by the lock cyl-
inders in the front doors and trunk.)
The alarm will also be activated if the control module/re-
ceiver detects voltage from the ignition before either of the
following conditions occur:
S An UNLOCK message is received from the trans-
mitter.
S Key operation is indicated by the tamper switches.
SIREN (GENERAL ONLY)
The remote keyless entry system is armed when the
LOCK message is received from the transmitter when the
ignition is OFF. When the system is armed, it will activate
the siren and flash the turn signals for 28 seconds if any
of the following conditions occur:
S Close all the windows.
S Turn the ignition key to LOCK and remove the key.
S Have all passengers get out of the vehicle.
S Close all doors, the hood and the turnk lid.
S The control module/receiver detects ignition voltage
while the system is armed.
The siren will not operate if any of the following conditions
occur after the system has been armed:
S The door is opened with the key.
S The trunk is opened with the key.
S The UNLOCK or LOCK button on the remote trans-
mitter is pressed within 2 seconds after the siren is
activated.
VEHICLE LOCATOR
The remote keyless entry system assists the driver in lo-
cating the vehicle. When the vehicle is unlocked with the
remote control, the turn signals flash twice to indicate the
location of the vehicle. The duration of the flashes and the
