Cautions • This unit is designed for negative ground 12 V DC operation only. • Do not get the leads 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 ground leads to a common ground point. • Be sure to insulate any loose unconnected leads with electrical tape for safety. • The use of optical instruments with this product will increase eye hazard. Notes on the power supply lead (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 list (EI) • The numbers in the list are keyed to those in the instructions. • The bracket ® and the protection collar ® are attached to the unit before shipping. Before mounting the unit, use the release keys ® to remove the bracket 0 and the protection collar 0 from the unit. For details, see "Removing the protection collar and the bracket (0)" on the reverse side of the sheet. • Keep the release keys ® for future use as they are also necessary if you remove the unit from your car. Caution Handle the bracket 0 carefully to avoid injuring your fingers. Catch Note Before installing, make sure that the catches on both sides of the bracket 0 are bent inwards 2 mm ('h, in). If the catches are straight or bent outwards, the unit will not be installed securely and may spring out. (a Connection example Notes (IEUB) • Be sure to connect the ground lead before connecting the amplifier. • If you connect an optional power amplifier and do not use the built-in amplifier, the beep sound will be deactivated. Connection diagram (1g) 0 To a metal surface of the car First connect the black ground lead, then connect the yellow and red power input leads. To the power antenna control lead or power supply lead of antenna booster amplifier Notes • It is not necessary to connect this lead if there is no power antenna or antenna booster, or with a manually-operated telescopic antenna. • When your car has a built-in FM/AM antenna in the rear/side glass, see "Notes on the control and o power supply leads." To AMP REMOTE IN of an optional power amplifier This connection is only for amplifiers. Connecting any other system may damage the unit. o To the +12 V power terminal which is energized in the accessory position of the ignition key switch Notes • If there is no accessory position, connect to the +12 V power (battery) terminal which is energized at all times. Be sure to connect the black ground lead to a metal surface of the car first. • When your car has a built-in FM/AM antenna in the rear/side glass, see "Notes on the control and power supply leads." 03 To the +12 V power terminal which is energized at all times Be sure to connect the black ground lead to a metal surface of the car first. Notes on the control and power supply leads • The power antenna control lead (blue) supplies +12 V DC when you turn on the tuner. • When your car has built-in FM/AM antenna in the rear/ side glass, connect the power antenna control lead (blue) or the accessory power input lead (red) to the power terminal of the existing antenna booster. For details, consult your dealer. • A power antenna 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 ground 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 leads 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 leads to each other. Note on connection If speaker and amplifier are not connected correctly, "FAILURE" appears in the display. In this case, make sure the speaker and amplifier are connected correctly.
