Setup
- Placement: Position the M604 speaker system on a stable, flat surface. The system is designed for tabletop use and can also be wall-mounted (mounting hardware not included). Ensure adequate ventilation around the unit.
- Connect Power: Connect the power supply to the DC input port on the back of the M604 system, then plug the power supply into a standard electrical outlet.
- Docking Your Zune:
- Gently place your Zune player into the built-in docking cradle located at the front of the M604. Ensure it is seated firmly. The Zune will begin charging automatically.
- Note: Some Zune models, such as the Zune 80GB, may not fit the dock connector directly. In such cases, use the auxiliary input for audio playback.
- Connecting Other Audio Devices (Auxiliary Input):
- For MP3 players, iPods (non-Zune), or other audio sources, use the provided 3.5 mm stereo cable.
- Connect one end of the 3.5 mm stereo cable to the headphone jack or line-out port of your external audio device.
- Connect the other end of the cable to the AUX IN port on the M604 system.
- If using a non-Zune device, you may use the universal MP3 cradle to support it, though it will not charge the device.
- Connecting to a Television (Composite Video Output):
- If your Zune supports video output, you can connect the M604 to a television to view videos.
- Connect a composite video cable (not included) from the VIDEO OUT port on the M604 to the video input port on your television.
- Select the appropriate video input channel on your television.
Operating Instructions
Power On/Off
- Press the Power button on the M604 unit or the wireless remote control to turn the system on or off.
Zune Playback
- Once your Zune is docked, it will automatically switch audio output to the M604 system.
- Use the controls on your Zune or the wireless remote control to manage playback:
- Play/Pause: Press the Play/Pause button.
- Skip Tracks: Use the Forward/Back buttons to navigate between songs.
- Volume: Adjust the volume using the Volume Up/Down buttons.
- Bass/Treble: The remote control allows for fine-tuning of bass and treble levels.
- Note: The remote control is designed for basic playback functions and volume/tone adjustments. Navigating Zune menus must be done directly on the Zune device.
Auxiliary Input Playback
- Ensure your external audio device is connected to the AUX IN port.
- Select the auxiliary input source on the M604 (refer to the unit's controls if available, or it may auto-detect).
- Control playback (play, pause, skip) directly from your external audio device. Volume can be adjusted on both the external device and the M604.
Headphone Jack
- For private listening, plug standard headphones into the headphone jack on the M604. This will mute the main speakers.
Maintenance
- Cleaning: Disconnect the power before cleaning. Use a soft, dry cloth to wipe the exterior surfaces of the M604. Do not use liquid cleaners or abrasive materials, as they may damage the finish.
- Storage: If storing the unit for an extended period, disconnect it from power and store it in a cool, dry place away from direct sunlight and extreme temperatures.
