Radio, Antitheft - Review
BULLETIN NO. 206
DATE:
November, 1986
SUBJECT:
ALPINE ANTI-THEFT RADIO
MODELS:
All so equipped
The new anti-theft radio operation and "coding" is outlined in detail in the radio owners handbook. Please read it to avoid problems. Dealer
responsibilities and possible problems that can occur are outlined in this bulletin for review by all service personnel.
A brief review of the computerized protection is first necessary in order to understand "why" procedures must be followed and how "possible problems"
can occur if procedures are not followed.
ANTI-THEFT COMPUTERIZED PROTECTION
The microprocessor controlling the radio is assigned a 5-digit "anti-theft code" as printed on the identification cards on the last page of the radio owners
manual. Should the voltage supply to the radio become disconnected (due to theft or electrical repairs), or become very low (due to insufficient battery
charge), the radio and cassette will not operate when voltage is later restored. The display will show the word "CODE". Unless the 5-digit "anti-theft
code" ASSIGNED TO THAT RADIO is entered, the radio will not operate, thereby reducing the market potential for stolen radios. It is extremely
unlikely that the correct 5-digit code can be guessed.
ANTI-THEFT CODE ENTRY
1.
When "CODE" appears in the display, the 5-digit "anti-theft code" printed on the "anti-theft code" radio identification cards must be entered using
the radio pushbuttons numbered 1 to 5.
a.
If a "beep" is heard while entering the 5-digit code, STOP. Do not continue. Begin the code entry again.
b.
If an error is made in code entry, REPEATEDLY press any of the 5 pushbuttons until a "beep" is heard, then STOP. Begin the code entry
again.
c.
NOTE: If the assigned "anti-theft code" is not entered in THREE consecutive tries, the microprocessor will not accept any more code
entries unless the radio is allowed to remain on continuously for one hour. After one hour of "on" time, it will again accept only three
additional tries and this process will repeat itself.
PORT RESPONSIBILITY
2.
Install radio - check only that "CODE" appears in display. Since the radio is inoperative unless programmed, and it is imperative that maximum
security of the codes be maintained, a further functional test must not be made.
3.
Place radio owners manual packet in glove box - DO NOT OPEN OR BREAK SEAL
Possible Problem:
4.
The port installer or convoy driver, etc. touches one of the buttons accidentally. The code entry is out of sequence.
Solution:
Handle as in 1a.
Possible Problem:
5.
The port installer or convoy driver, etc. keeps pressing the code buttons and uses up the first three "tries".
Solution:
Handle as in 1c.
DEALER RESPONSIBILITY - UPON VEHICLE RECEIPT
6.
Remove anti-theft packet (containing radio owners manual and hang tag) from glove box - store with vehicle papers in sales file. Write vehicle
stock number in pencil on envelope for identification.
7.
OPTIONAL - Remove radio also, write radio serial number on envelope. Reinstall radio at PDI.
DEALER RESPONSIBILITY - AT PDI
