Retainthesescrewsforfutureusewhentransportingtheunitforservice/maintenance.  
l Caution l  
After removing the transport lock screws, place the supplied seals over the screw  
holes. These seals are used to keep dust out of the unit, which could cause a  
malfunction.  
Installation and Wiring Precautions  
To prevent a short-circuit,  
l Be sure to turn off the ignition and remove the negative (-) battery cable, prior to installation.  
l Connect power wires last.

Note  
If the changer is to be installed in a car that is equipped with an on-board drive or navigation computer, do not disconnect  
the battery cable. If the cable is disconnected, the computer memory may be lost. Under these conditions, use extra  
caution during installation, not to cause a short circuit.  
Do not install the unit in the following locations.  
l Locations exposed to direct sunlight.  
l Where hot air is discharged from the car heater.  
l In areas subject to extreme temperatures.

Incorrect installation can cause the sound to "skip" when playing a disc.  
Mount the unit firmly in place, using the supplied brackets and screws.

l Be sure to use the supplied screws.  
l Be careful not to snag any wires when tightening screws.  
l Do not use any of the screws that are part of the brake or steering system, to install the unit.  
5
l This unit cannot be installed on its side, end, or upside down. Installation in such positions will cause malfunctioning

INSTALLATION  
The unit can be installed horizontally, vertically or at a 45° angle. The position of the built-in anti-vibration springs (left and right side), must  
correspond to the mounting position chosen. If the springs are not set correctly for the type of installation chosen, the anti-vibration  
compensation will not be effective and vibration may cause the disc to skip.  
HORIZONTAL INSTALLATION  
Set the anti-vibration springs to  
position "H".

Set the anti-vibration springs to  
position "V".  
45° ANGLE INSTALLATION

NOTE:If mounting surface is carpeted, use caution  
when drilling holes to prevent drill bit from  
catching on carpet. Cut holes in carpet  
before drilling into sub-surface.  
Drill holes 1/8" (4mm) in diameter.  
Never mount the unit near the fuel tank.

Secure the unit in place, using four large self-tapping Phillips  
head screws.  
Use RTV (silicone sealer) on screw threads or around  
the holes to prevent moisture intrusion.

SYSTEM WIRING AND ADJUSTMENT  
IMPORTANT - Some import cars use a special dual antenna “Diversity"system.  
If your car has this type of antenna system, you will find the antenna cable will  
not fit the socket on the FM modulator. Use of the ACC-40 with “Diversity"  
systems is not recommended. You may also find some GM cars and others  
have an antenna plug that is too small to mate with the socket on the FM  
modulator. If this is found, call Audiovox’s Toll-Free Assistance for a special  
adaptor. This adaptor can also be purchased at most car stereo installation  
center.

ADJUSTMENT OF FM MODULATOR OUTPUT FREQUENCY  
l If there is interference from a local station or a clear signal cannot be obtained  
on 89.1 MHz., change the position of the frequency select switch on the side of  
the FM Modulator and tune the radio to 88.7 MHz. when using the CD changer.  
l Select the frequency before mounting the FM Modulator.

l Radio sensitivity may be slightly reduced when the FM Modulator is connected.  
ADJUSTMENT OF FM MODULATOR AUDIO LEVEL  
The audio level from the modulator is factory-set to provide the correct volume  
balance between radio and CD changer in the majority of installations and usually  
will not require any adjustment. If, however, a large difference in volume level is  
notedwhenswitchingbetweenCDchangerandFMradiooperation,theaudiolevel  
from the CD changer may be adjusted as follows:  
Move to 88.7M Position  
#0 Phillips Screwdriver  
1. With the CD changer off, tune to an FM station and adjust the volume control on  
the radio to a normal listening level.  
FM Modulator  
2. Leaving the volume control at the setting, turn on the CD changer and tune the  
radio to the modulator output frequency (89.1 or 88.7 MHz.).  
3. Select a LOUD section of the CD. If the volume level is comparable to that of  
the FM station in step 1, no adjustment is necessary. If it is noticeably louder or  
more quiet than that of the radio station, use a # 0 Phillips screwdriver to adjust  
the "AUDIO LEVEL" control on the modulator so that the CD changer volume  
is comparable to that of the radio station.  
IMPORTANT: If the modulator audio level is adjusted too high, it may result in  
unacceptable levels of distortion during loud sections of CD's. If set too low, it may  
result in poor signal/noise levels during CD changer operation.
