1. SETTING SYSTEM
The system is in operation once the customer has pushed the required buttons and entered the custom-
erselected 3±digit ID number.
(Refer to the 0/M section, ºSetting the anti±theft systemº')
HINT:
wWhen the audio system is shipped the ID number has not been input, so the anti±theft system is
not in operation.
wIf the ID number has not been input, the audio system remains the same as a normal audio system.
2. ANTI±THEFT SYSTEM OPERATION
If the normal electrical power source (connector or battery terminal) is cut off, the audio system becomes
inoperable, even if the power supply resumes.
3. CANCELLING SYSTEM
The ID number chosen by the customer is input to cancel the anti±theft system.
(Refer to the 0/M section, ºif the system is activatedº)
HINT: To change or cancel the ID number, please refer to the 0/M section, ºCancelling the systemº.
AUDIO SYSTEM
System Description
Anti±Theft System (USA only)
The anti±theft system is only provided for audio systems
equipped with an Acoustic Flavor function.
HINT: The words º'ANTI±THEFT SYSTEMº are displayed
on the cassette tape slot cover.
For operation instructions for the anti±theft system,
please consult the audio system section in the Owner's
Manual (hereafter called O/M).

6, 7 and 8. Connect the negative (±) lead to terminal 3.
(c) Check that there is battery voltage.
HINT: Measure the voltage within 7 seconds after con±
necting the positive (+) battery lead to terminals 8.
2. INSPECT RELAY OPERATION (ANTENNA DOWN)
(a) Connect the voltmeter positive (+) lead to terminal 4
and the negative (±) lead to terminal 1.
(b) Connect the positive (+) lead from the battery to terminals
6 and 7. Connect the negative (±) lead to terminal 2.
(e) Disconnect the positive (+) battery lead from terminal 6.
(d) Check that there is battery voltage.
HINT: Measure the voltage within 7 seconds after disconnect±
ing the positive (+) battery lead from terminal 6.
3. INSPECT RELAY OPERATION (ANTENNA STOP)
(a) Connect the voltmeter positive (+) lead to terminal 1
and the negative (±) lead to terminal 4.
(b) Connect the positive (+) lead from the ±battery to termi-
nals 7 and 9. Connect the negative (±) lead to terminal 2.
(c) Check that there is no battery voltage.
If operation is not as specified, replace the relay.
Antenna Motor
INSPECTION OF ANTENNA MOTOR
INSPECT LIMIT SWITCH OPERATION
(a) If the motor stops with the antenna up, check that
there is no continuity between terminals A±2 and
B±1.
(b) If the motor stops with the antenna down, check that
there is no continuity between terminals A±3 and
B±1.
If continuity is not as specified, replace the motor.

CLOCK
Troubleshooting
CLOCK WILL NOT OPERATE
Check amount of time the clock loses or gains per day or a week against the allowable error table.
Check to see if there is 11 ± 15V
on terminal6 of connector on clock side.
Check to see if clock adjust-
ing button is sticking i n posi-
tion and has failed to return.
Check to see if there is volt-
age at terminal B or connec-
tor or clock side.
Check to see if clock ground
wire is loose or rusted.Check to see if battery voltage
is over 11 V with no load.Repair if necessary or re-
place clock. Locate trouble and repair or re-
place fuse as necessary.
Locate cause and repair,
or recharge battery. Check to see if connector on
clock side is loose or rusted.

1. INSPECT ALLOWABLE ERROR OF CLOCK
Check the allowable error of the clock.
Allowable error (per day):
+ 1.5 seconds
2. ADJUSTMENT OF CLOCK
Adjustment of the quartz clock requires a precise digital
counter. Adjustment must be made in shop specified by-
the manufacturer.
3. SETTING OF CLOCK
(a) Connect the battery terminal.
(b) Check the clock to see that it is running, and then set
it to the correct time.
HINT: Whenever the battery terminal is disconnected,
make sure to set the clock to the correct time after reco
necting the battery.
