Congratulations on your new FMR-1 converted radio. With the FMR-1 installed in your radio you will experience unrivaled performance, features and reliability all while retaining the radios original appearance.

Installation:

Before starting installation you should remove one of the battery cables.

Your radio came with a short 12 pin wiring harness. This harness will be used to connect the radio to your vehicle. The pinout is as follows:

The Red wire should be connected to an Ignition switched circuit that is fused at no less than 10A. It should not be connected to a continuous battery circuit. The Black wire can be attached to a convenient point on the dashboard. The Orange wire should connect to the original dash lamp circuit. The Blue wire is a switched power output that can be used for power antennas, etc. Do not connect this wire to battery!

The remaining wires are for the speakers. To achieve such high power levels, the FMR-1 uses a bridged amplifier design where neither speaker lead is ground. Both wires actively drive the speaker so speakers with one side already grounded as used in some original applications must not be used. The FMR-1 performs best with speakers of 4 ohm impedance, a

SPL rating of at least 90 and a power rating of at least 30W (50W for full output). The FMR-1 can drive 1, 2 or 4 speakers as follows:

For a 1 speaker installation the speaker can be connected to any one of the four outputs. The FMR-1 will detect that only one speaker is attached and enable mono mode while disabling the balance and fader controls.

For a 2 speaker installation, the speakers can be attached in one of three ways as follows:

1) If the two speakers are attached to either the front left/right pair or the rear left/right pair the FMR-1 will enable stereo mode and the balance control.

2) If one speaker is attached to the left or right front output and the other speakers is attached to the same channel (left or right) rear output, the FMR-1 will enable mono mode and the fader control.

3) If one speaker is attached to the left or right front output and the other speakers is attached to the opposite channel (right or left) rear output, the FMR-1 will enable stereo mode and the fader control.

For a 4 speaker installation all the speaker outputs will be used and the

FMR-1 will enable stereo, balance and fader controls.

All unused wires should be taped up so they can’t short out. The radio can now be mounted back into the vehicle as original and connected to the new wiring harness. Reattach the battery cable. Installation is now complete.

Operation:

Your converted radio will operate as before but with new performance and features.

LED: If your radio has a front panel status LED installed, it will display the current operating mode as for AM, FM, Bluetooth, Auxiliary and

Errors. The color of the LED for each mode will be as shown in the

Configuration section of this manual.

Mode Select: Mode selection (AM, FM, Aux) is accomplished in different ways depending on your radio. In the following description, power cycling refers to quickly switching the radio off and back on.

Each time this is done the radio with change to the next mode. The radio will always return to the last mode selected when first turned on.

If your radio has an AM/FM band switch, it will work as normal, otherwise AM/FM selection is done by power cycling.

The Auxiliary Input is normally selected by tuning the radio to the low end of the dial. This position can be set on one of the pushbuttons to make accessing the Aux input very easy. Alternatively your radio may be set to use the power cycling method for the Aux input.

Balance/Fader: If your radio has balance/fader controls they will operate as before. If your radio does not have balance/fader controls, the

FMR-1 enables virtual controls.

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-1 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-1 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.

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-1 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-1 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-1 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.

Overheating: If the FMR-1 ever overheats in operation the front panel

LED (if installed) will blink 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 BT-1 Bluetooth adapter, the

FMR-1 will automatically mute the radio and switch to the Bluetooth input when audio is streaming or a call is received. If your radio was equipped with a USB-1 adapter, the FMR-1 will automatically mute the radio and switch to the USB input whenever a USB FLASH drive is inserted. Please refer to the appropriate User Manual for complete information.
