Catch
Cautions
• This unit is designed for negative earth 12 V DC
operation only.
• Do not get the wires under a screw, or caught in
moving parts (e.g. seat railing).
• Before making connections, turn the car ignition off
to avoid short circuits.
• Connect the yellow and red power input leads only
after all other leads have been connected.
• Run all earth wires to a common earth point.
• Be sure to insulate any loose unconnected wires with
electrical tape for safety.
Notes on the power supply cord (yellow)
• When connecting this unit in combination with other
stereo components, the connected car circuit’s rating
must be higher than the sum of each component’s
fuse.
• When no car circuits are rated high enough, connect
the unit directly to the battery.
Parts Iist (1)
• The numbers in the list are keyed to those in the
instructions.
• The bracket 1 and the protection collar 5 are
attached to the unit before shipping. Before mounting
the unit, use the release keys 6 to remove the bracket
1
 and the protection collar 5 from the unit. For
details, see “Removing the protection collar and the
bracket (4)” on the reverse side of the sheet.
• Keep the release keys 6 for future use as they are
also necessary if you remove the unit from your
car.
Caution
Handle the bracket 1 carefully to avoid injuring your
fingers.
Note
Before installing, make sure that the catches on both
sides of the bracket 
1 are bent inwards 2 mm. If the
catches are straight or bent outwards, the unit will not
be installed securely and may spring out.

Notes
• If there is no accessory position, connect to the
+12 V power (battery) terminal which is
energised at all times.
Be sure to connect the black earth lead to a
metal surface of the car first.
• When your car has a built-in FM/AM aerial in the
rear/side glass, see “Notes on the control and
power supply leads.”

To the +12 V power terminal which is energised at
all times
Be sure to connect the black earth lead to a metal
surface of the car first.
Notes on the control and power supply leads
• The power aerial control lead (blue) supplies +12 V
DC when you turn on the tuner.
• When your car has built-in FM/AM aerial in the rear/
side glass, connect the power aerial control lead
(blue) or the accessory power input lead (red) to the
power terminal of the existing aerial booster. For
details, consult your dealer.
• A power aerial without relay box cannot be used
with this unit.
Memory hold connection
When the yellow power input lead is connected,
power will always be supplied to the memory circuit
even when the ignition key is turned off.
Notes on speaker connection
• Before connecting the speakers, turn the unit off.
• Use speakers with an impedance of 4 to 8 ohms, and
with adequate power handling capacities to avoid its
damage.
• Do not connect the speaker terminals to the car
chassis, or connect the terminals of the right
speakers with those of the left speaker.
• Do not connect the earth lead of this unit to the
negative (–) terminal of the speaker.
• Do not attempt to connect the speakers in parallel.
• Connect only passive speakers. Connecting active
speakers (with built-in amplifiers) to the speaker
terminals may damage the unit.
• To avoid a malfunction, do not use the built-in
speaker wires installed in your car if the unit shares a
common negative (–) lead for the right and left
speakers.
• Do not connect the unit’s speaker cords to each
other.
