Check loudspeaker wiring
This product contains a biamp. It is important not to connect the front
loudspeaker ground to the rear speaker ground.
Faulty loudspeaker

maximum power output. Otherwise the power and ground wire might be too
small of a gauge. Use 10amp cable or more.
Reduce the bass effect or switch off the loudness mode

Precautions and maintenance
1. Reset function
A microprocessor reset button has been provided to facilitate manual resetting of the
internal microprocessor in the unlikely event that the player fails to operate correctly.
Should it be necessary to reset the microprocessor, simply open the face, remove
rubber plug and press reset button.
Note: It will be necessary to re-enter the radio preset memories as these will have
been erased when the microprocessor is reset. After resetting the player, ensure
that all functions are operating correctly.
2. General Precautions
If the unit has become extremely hot we strongly recommend that you allow it to cool
down before using. Take care of your CDs to preserve the quality of the recording.
Do not allow them to be exposed to direct sunlight. Store them in a place protected
from dirt and dust and avoid handling them with oily, greasy or wet hands.
Be sure the CD is put into the CD slot label side up.
CONNECTOR PIN: Always keep connector pin clean.
If the PIN connector looks dirty, use cotton tips to clean it, so as to avoid any
unexpected malfunction caused by dirt.

Important notes
Prior to the final installation, carry out a sound check. If high distortion or intermittent
sound is experienced, it is possible that the wiring from the CD receiver to the boat's
electrical system is poor or that the battery needs recharging.
If the battery and its charging circuit are OK, then rewire the yellow fused wire of the
CD player directly to the positive terminal (+) of the boat battery.
Marine accessory shops stock the connector blocks and the 10 Amp cable that may
be necessary for extending the fuse wire connection.
Grounding
Make sure that the black wire on the wiring harness is connected to a good ground
point on the boat. If the chassis of the boat is used as a grounding point, make sure
that the surface is scraped clean of paint before attaching the wire to it.
It is preferable to connect the black ground wire directly to negative terminal (-) of
the boat battery.
Warning: polarity...
This model is only suitable for use in boats which have a Negative ground system,
e. g. : the negative terminal of the boat battery is connected to the chassis.
Connecting the Speakers and Power Cables
Before you wire your system, disconnect your boat battery's positive (+) cable.
This helps prevent damage in case of a short. When you complete the wiring,
reconnect the battery cable and test your marine stereo. When connecting your
marine stereo's black ground wire, be sure to connect the wire to a metal part of
your boat or preferably to the negative (-) terminal of the boat battery.
