Activating the coding
If "
CODE
" appears in the diplay, coding is
not activated.
If "
SAFE
" appears in the display, coding is
activated.
Your car radio has been designed throughout
to ensure maintenance-free operation over an
extended period of time.
If a malfunction
should occur, please consult your dealer.
In the Federal Republic of Germany, Grundig
car radios can be exchanged by your dealer
on request for a works-tested exchange unit
in the event of a defect occuring.
Please note:
It is a condition for your dealer to participate
in this exchange system that the guarantee
seal on your car radio is not damaged.
Cassettes must not be subjected to high
temperatures (see manufacturer's specifica-
tions) and should be put into their case after
use.
The front panel of the car radio must only be
cleaned with a soft, dust-absorbent, anti-static
cloth. Polishing and cleansing agents may
damage the surface of the trimplate.
The tape head must be free of tape dust in
order to avoid losses in the treble tones
during playback. Therefore you should clean
the tape head with a cleaning cassette after
every 50 –100 hours of operation.
Maintenance and Care
EXPERT
Coding
Your personal code number is on the identity
card of your car radio.
Coding is not activated when the radio leaves
the factory.
If you have “activated” your car radio's
coding:
As soon as you disconnect the car radio from
the car battery (or permanent plus terminal
30), it is electronically blocked.
Only you are able to put it back into operation
by entering your personal Code Number.
If the Code Number is lost (Identity Card),
only a dealer can put the radio back into
operation after you provide proof of owner-
ship and pay a fee.
Is the coding activated?
Activate the expert mode and turn the
¢
¢
rotary knob until the display indicates
"
SAFE
" or "
CODE
".

Waiting periods
To prevent deactivation of the coding being
possible by trial and error, waiting periods are
required between attempts. During these wait-
ing periods the car radio can be switched on
and off but will not play.
During the waiting period
the car radio needs not be switched on, but it
must be connected to the permanent plus ter-
minal. As long as the display indicates "
SAFE
",
the waiting period has not yet elapsed.
The waiting period is over when the number
of the next attempt is visible in the display,
e.g.
"
2 - - - -
".
The table shows
the waiting
periods between
the individual
attempts.
Waiting period
after the 7th
attempt is
always 24hrs!
After the 6th
attempt we
recommend having a dealer complete the
“Return to operation” or “Deactivate coding”
process.
