When Parked
Parking in direct sunlight can produce very high temperatures inside your vehicle. Give the interior a
chance to cool down before switching the unit on.
Use the Proper Power Supply
This equipment is designed to operate off a 12 volt, negative ground battery system (the normal system
in a North American vehicle.)
Protect the Tape Mechanism
Keep magnets, screwdrivers, or other metallic objects away from the tape mechanism and tape head to
prevent poor performance or malfunctions.
Use Authorized Service Centers
Do not attempt to disassemble or adjust this precision equipment. Please refer to the Servicenter list
included with this product for service assistance.

❏Required Tools
You'll need a screwdriver, a 1.5 volt AA battery
and the following:
12 V DC ELECTRICAL SIDE-CUT
TEST BULB TAPE PLIERS
❏Dashboard Specifications
❏Identify All Leads
The first step in installation is to identify all the
vehicle wires you'll use when hooking up your
sound system.
As you identify each wire, we suggest that you
label it using masking tape and a permanent
marker. This will help avoid confusion when
making connections later.
Note: Do not connect the power connector to the
stereo unit until you have made all connections.
If there are no plastic caps on the stereo hooking
wires, insulate all exposed leads with electrical
tape until you are ready to use them. Identify the
leads in the following order.
Power Lead
If your vehicle has a radio or is pre-wired for one:
Cut the connector wires one at a time from the
plug (leaving the leads as long as possible) so
that you can work with individual leads.
Turn the ignition on to the accessory position, and
ground one lead of the test bulb to the chassis.
Touch the other lead of the test bulb to each of
the exposed wires from the cut radio connector
plug. Touch one wire at a time until you find the
outlet that causes the test bulb to light.
Now turn the ignition off and then on. If the bulb
also turns off and on, that outlet is the vehicle
power lead.
If your vehicle is not wired for an audio unit:
Go to the fuse block and find the fuse port for
radio (RADIO), accessory (ACC), or ignition
(IGN).
Battery Lead
If your stereo unit has a yellow lead, you will
need to locate the vehicle's battery lead.
Otherwise you may ignore this procedure. (The
yellow battery lead provides continuous power to
maintain a clock, memory storage or other
function.)
If your vehicle has a radio or is pre-wired for one:
With the ignition and headlights off, identify the
vehicle battery lead by grounding one lead of the
test bulb to the chassis and checking the
remaining exposed wires from the cut radio
connector plug.
If your vehicle is not wired for an audio unit:
Go to the fuse block and find the fuse port for the
battery, usually marked BAT.
Speakers
Identify the vehicle speaker leads. There will be
two leads for each speaker, usually color coded.
