CATS (Code) System/RHD
NOTE:
+This system is used for code indicator-equipped radios on all models except the Europe LHD
model.
+The Europe LHD model has a NATS-linked anti-theft function that renders the code system inop-
erable.
DESCRIPTION
By using a personal 4-digit code known only to the vehicle owner, the possibility of the audio unit being sto-
len is effectively reduced, because without the code the unit can not be activated. When in normal use, the
unit is unlocked and accessible in the usual way.
If however, someone attempts to remove the unit or the battery cable is disconnected, the anti-theft system
activates and the unit ``locks''. The only way it can be unlocked is by entering a personal code number known
only by the owner.
UNLOCKING THE UNIT (How to enter a personal code number)
+If the battery supply to the vehicle is interrupted by accident for some reason, the unit will lock.
To unlock the unit, proceed as follows:
1. Press the power/volume control knob to turn the unit on.
2. ``CODE IN'' is displayed.
3. Input your personal code by pressing the preset buttons (1 to 4).
4. Press the
button.
5. If the entered code number is correct, the radio turns on.
When the code is incorrect
1. If the entered code is incorrect, the unit becomes inoperable for 10 seconds for the ®rst three attempts,
then the code input mode is automatically set (``CODE IN'' is displayed).
2. If the code is incorrect the fourth time, the unit becomes inoperable for 60 minutes and ``
'' is displayed.
After 60 minutes, the code input mode is automatically set (``CODE IN'' is displayed).
NOTE:
If the above is repeated 17 times, the unit will lock and ``LOCKED'' is displayed.
3. After ``LOCKED'' is displayed, radio can be returned to the code input mode only within three attempts as
follows. (Only three attempts are allowed to unlock the unit.)
a. Press the power/volume control knob while pushing both the MOD and TA switches.
b. The unit then returns to the code input mode.
CAUTION:
If the third attempt is unsuccessful, the unit will lock permanently.
