Playing a Cassette  Tape 
Your  tape player is built  to work  best  with  tapes that are

that  are 
so thin  they  may  not  work well  in this player. 
To load a cassette  tape  with the ignition off, press EJECT 
or RECALL.  Then,  insert  the  cassette  tape. If the ignition 
is  on 
but the  radio  is off, the  tape  will  begin  playing. 
Once  the tape  is playing, use the 
VOL, BAL, FADE, 
BASS and TREB controls  just as you do  for  the radio. 
The  tape symbol and  a direction arrow  will  be on the 
display whenever 
a tape  is being played. Anytime a tape 
is inserted,  the top side is selected for play  first.

Theft-Deterrent  Feature 
THEFTLOCK@ is designed  to  discourage  theft of your 
radio. 
It works  by using a secret  code to disable all  radio 
functions  whenever  battery power is removed. 
The  THEFTLOCK  feature  for  the radio may  be  used  or 
ignored. 
If ignored,  the system plays  normally and the 
radio is not protected  by the  feature. If THEFTLOCK  is 
activated, your radio will 
not operate if stolen. 
When  THEFTLOCK  is activated,  the radio  will display 
LOC to indicate a locked condition  anytime battery 
power has been  interrupted.  If your battery  loses power 
for  any reason,  you  must  unlock  the radio  with 
the secret 
code  before 
it will operate. 
Activating  the  Theft-Deterrent  Feature 
The instructions  which follow  explain  how to enter your 
secret  code to activate 
the THEFTLOCK  system. It is 
recommended  that  you read through  all nine steps 
before starting 
the procedure. 
NOTE: 
If you  allow  more than 15 seconds  to  elapse 
between  any  steps,  the radio  automatically  reverts  to 
time and you  must start the procedure  over  at Step 4.
