Instruction

Installing the unit

•Mount the unit either inside the trunk or under a seat.

•Choose the mounting location carefully so the unit will not interfere with the normal movements of the driver and it will not be exposed to direct sunlight or hot air from the heater.

•Do not install the unit under the floor carpet, where the heat dissipation from the unit will be considerably impaired.

First, place the unit where you plan to install it, and mark the positions of the four screw holes on the mounting surface.

Screw hole:

ø3.3 mm (

Notes

• Use only the supplied screws.

• Be sure not to damage the fuel tank or brake line with the tapping screws.

Fuse replacement

If the fuse blows, check the power connection and replace the fuse. If the fuse blows again after replacement, there may be an internal malfunction.

Warning

Use a fuse with the specified amperage rating. Use of a higher amperage fuse may cause serious damage.

Cautions

• This unit is designed for negative ground 12 V DC operation only.

• Before making connections, turn the car ignition off to avoid short circuits.

• Connect the yellow power input cord only after all other cords have been connected.

• Run all ground leads to a common ground point.

Note on Printed Wiring Board:

• X : parts extracted from the component side.

• Y : parts extracted from the conductor side.

• : Pattern from the side which enables seeing. (The other layers' patterns are not indicated.)

Caution: Pattern face side: Parts on the pattern f ace side seen from (Conductor Side) the pattern face are indicated. Parts face side: Parts on the parts face side seen from (Component Side) the parts face are indicated.

Note on Schematic Diagram:

• All capacitors are in µF unless otherwise noted. pF: µµF 50 WV or less are not indicated except for electrolytics and tantalums.

• All resistors are in Ω and 1/ specified.

• C : panel designation.

• A : B+ Line.

•Power voltage is dc 14.4V and fed with regulated dc power supply from BATT cords.

•Voltages and waveforms are dc with respect to ground under no-signal (detuned) and master unit connected conditions. no mark : XM

•Voltages are taken with a VOM (Input impedance 10 MΩ). Voltage var iations may be noted due to normal production tolerances.

•Waveforms are taken with a oscilloscope. Voltage var iations may be noted due to normal production tolerances.

• Circled numbers refer to waveforms.
