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

•Connect the yellow and red power input leads only after all other leads have been connected.
•Run all ground wires to a common ground point.

The AM (FM) tuning interval is factory-set to the 9K (50 K) position. If the frequency allocation system
of your country is based on 10 kHz (200 kHz) interval, set the switch on the bottom of the unit to the

Connection Example
Notes on the control leads
•The ANT REM lead (blue) supplies +12 V DC when you turn on the
unit. When the ANT REM lead is connected to the power antenna, the
antenna will be extended as long as the unit is turned on.
•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. Otherwise, the speakers may be damaged.
•Do not connect the terminals of the speaker system to the car chassis, and
do not connect the terminals of the right speaker with those of the left
speaker.
•Do not attempt to connect the speakers in parallel.
•Do not connect any active speakers (with built-in amplifiers) to the
speaker terminals of the unit. Doing so may damage the active speakers.
Therefore, be sure to connect passive speakers to these terminals.
