If
your car still has the factory Heidelberg radio/cassette head unit but
no Operating Instruction manual, the following list outlines its basic
functions.
On/Off, Volume knob: Turn the knob clockwise to switch the unit
on; continue turning to increase the volume. Turn the knob
counterclockwise to decrease volume and to switch the unit off.
When powering the unit on/off, a <click> should be heard.

or counterclockwise to adjust the sound balance of right-to-left
speakers. While pulling the knob out, turn clockwise to increase
treble, turn counterclockwise to decrease treble.
Bass control: Turn tab clockwise to increase bass, turn
counterclockwise to decrease bass.
Fader control: Adjusts the sound balance of the front and rear
speakers.
< > buttons: These are the tuning buttons. When the <
button is pressed, the radio frequencies count down; when the > button
is pressed, the radio frequencies count up. This is done manually
or automatically, depending on where sensitivity selector switch is set.
Sensitivity selector switch: With the switch at the MNL position,
radio stations are selected manually. With the switch at the
center SEEK position, radio stations are selected automatically,
including weaker stations. With the switch at the right SEEK
position, only powerful radio stations are selected automatically.

station, press and hold the desired button. The station will mute
for a few seconds; when you hear the station again, release the button.
A maximum of 5 FM stations and 5 AM stations can be stored.
AM/FM button: Switches from AM to FM and vice versa.
SCAN button: With the sensitivity selector switch in the
MNL position, pressing the SCAN button will automatically search for
stations. When a station is found, scanning will stop at that
station for 5 seconds. If you like the station, press SCAN again
to stop auto searching; if you don't like the station, after 5 seconds
the unit will search for the next available station.
METAL button: Press the button in for metal or CrO2 tapes; leave
the button out for regular tapes.
