OPERATING INSTRUCTIONS
SETTING UP FOR OPERATION
The PMC-50 FM Modulator/Wired Commander is designed to
permit operation of compatible Prestige CD changers through the
FM section of any car stereo system. Please check with your
Prestige car stereo specialist for recommendations of the CD
changer models that will work with the PMC-50. The specific
details on the handling of discs and the use of the CD magazine
(loading, removal, etc.) will be found within the Owner’s Manual of
the compatible changer.
Following the instructions in the owner’s manual of the compatible
CD changer, load the desired number of discs into the CD
magazine and insert the magazine into the changer.
Turn on the car stereo and select FM band operation. Tune the
radio to the frequency to which the PMC-50 has been set (see
“SETTING THE FM MODULATOR OUTPUT FREQUENCY” sec-
tion of this manual) or push the pre-set memory pushbutton that
has been set as per the above description.
SincethePMC-50/CDchangersystemwilloperatethroughtheFM
stereo section of your existing sound system, adjustment of the
audio functions (volume, tone, balance etc.) is made by using the
controls on the car stereo. Control of disc play is by the wired
commander of the PMC-50 which can be conveniently mounted to
the dashboard, as well as by the optional P-14R wireless remote
control. The output from the FM modulator of the PMC-50 is at
88.3, 88.7, 89.7, or 89.9 MHz. (which can be set by the user) on the
FM band. To simplify operation of the system, it is recommended
that a pre-set memory pushbutton on the radio be set to the
selected output frequency of the modulator. Consult the operating
instructions of the car stereo for directions on setting the memory
pushbuttons.
Turn on the changer system by pressing the Play/Pause button 2
on the commander. The display panel on the commander will
illuminate and play of the first disc in the magazine will begin.
Adjust the volume, tone, and balance to your taste by using the
controls on the car stereo.
When the last track on a disc has played, the unit will automatically
advance to and begin play of the next disc in the magazine. When
the last track on the last disc in the magazine has been played, the
unit will automatically return to the first disc and begin play again.
