Virtual Balance: Quickly twist the tone control back and forth twice
to the left. The tone control temporarily becomes the balance control.
A tone will alternate between the left and right channels to verify you
have entered the virtual balance control. You may adjust the balance
for as long as you wish. When finished, the FMR-2 waits a few
seconds and then signifies that the setting was accepted by playing a
tone. This setting is retained until it the next time it is changed.
Virtual Fader: Quickly twist the tone control back and forth twice
to the right. The tone control temporarily becomes the fader control.
A tone will alternate between the front and rear channels to verify
you have entered the virtual fader control. You may adjust the fader
for as long as you wish. When finished, the FMR-2 waits a few
seconds and then signifies that the setting was accepted by playing a
tone. This setting is retained until the next time it is changed.
Loudness Contouring: This is a method of contouring the audio
spectrum to match that of the human ear. This should normally be
enabled as it will make the audio sound more natural at all volume
levels. To enable Loudness Contouring, quickly twist the tone control
back and forth three times to the left. An ascending tone will be heard.
To disable Loudness Contouring and provide a flat frequency response,
quickly twist the tone control back and forth three times to the right. A
descending tone will be heard.
Tone Switch: If your radio has a tone switch rather than a tone control it
may have been configured to select between volume and tone functions
on the main volume control. In one position of the tone switch, the
volume control will function as normal. In the other position of the tone
switch it will function as the tone control with full compatibility with the
virtual controls as described above. When you switch from volume to
tone, the FMR-2 will hold the volume steady until you return to the
volume position of the tone switch. Since it is possible the volume
control could now be set to a very high volume depending on where it
was left after making adjustments to the tone and virtual controls, the
FMR-2 will beep once to alert you of this condition, and the volume
control will need to be lowered to at least the previous level before it
will start operating normally again. Also if the tone switch is set to the
tone position when the radio is first turned on, the volume will be at a
safe, preset level so that it will not damage the speakers.
Tuning: Your radio will tune as before including pushbuttons and
automatic Signal Seeking operation. Pushbuttons can be set for an AM
or FM station (radio must be in correct band mode for button). Signal
Seeking radios like the Wonderbar® and Town & Country will operate
as before including sensitivity (Town/Country) controls.
Line Out: Optional Line Out jacks may have been added to your radio if
requested. The five outputs (front/rear pair and subwoofer) can be
attached to an outboard amplifier. These outputs are post pre-amp and
are affected by the controls on the radio.
Troubleshooting:
Low Power: If the voltage to the radio drops to low for normal
operation, the front panel LED will alternate between green and red and
no audio will be heard until this situation is corrected.
No Sound: Make sure the radio is getting power. Check all fuses and
wiring. Make sure speakers are properly connected and in good working
order.
Weak/Noisy Reception: Make sure the antenna is connected to the
radio and in good working order. The cable for the antenna can become
damaged. Check for continuity between the center pin of the connector
and the antenna mast. Also check for shorts between the center pin and
the outer shield.
The FMR-2 uses sophisticated noise blankers to reduce or eliminate
most engine/generator noise. If engine or generator noise is still present,
investigate the cause of this noise, i.e. spark plugs and wires, generator/
alternator suppression condensers etc.
PowerOnDiagnostics: Each time the radio is powered on it uses a
sophisticated method to check the speaker outputs for problems. If
found, the specific speaker channel is disabled and the error is reported
on the front panel LED (if installed). The LED will flash a pattern
similar to that used by the automotive ODB standard. The pattern
consists of a number of flashes indicating which speaker followed by a
short pause, then another set of flashes indicating the specific problem. If
multiple faults are found, each of these patterns will be followed by a
long pause and the next fault will be displayed.

!1 - Left Front Speaker!1 - Short to Ground
!2 - Right Front Speaker!2 - Short to Battery
!3 - Left Rear Speaker!3 - Line shorted together
!4 - Right Rear Speaker!4 - Internal Error
Overheating: If the FMR-2 ever overheats in operation the front panel
LED (if installed) will pulsate slowly. No damage will occur to the radio
and it may start to lower the output power to bring the temperature back
down. This should never occur in normal operation.
Options:
If your radio was equipped with the BTU-2, BT-2 or USB-2 option
cards, the radio will automatically mute the radio and switch to the
option card when required. Please refer to the appropriate User Manual
that came with the option card for complete information.
