Trouble shooting Guide

Caution

1. CONNECTOR PINS: Always keep connector pins clean.

If the PIN connector looks dirty, use cotton tips to clean it, so as to avoid any unexpected malfunction caused by dirt.

2. In many respects, a stereo acts much like a computer and occasionally requires a reboot.

In the unlikely event of product malfunction, a reset can usually fix the issue.

A reset is accomplished by holding the BAND and Preset 1 button simultaneously until the unit turns off.

Installation

1. Precautions

Choose the mounting location carefully so that the unit will not interfere with the normal driving functions of the boat.

Avoid installing the unit where it would be subject to high temperature (such as from direct sunlight or hot air) or where it would be subject to dust, dirt or excessive vibration. Use only the supplied mounting hardware for a safe and secure installation.

2. Mounting angle adjustment

Adjust the mounting angle to less than 20 degrees from the horizontal position. Otherwise, the unit will skip beyond its intended level.

3. Supporting the unit

Failure to support the unit with the back bracket will reduce the life of the unit due to possible CD mechanism imbalance.

Important notes

Prior to the final installation, perform a sound check. If high distortion or intermittent sound is experienced, it is possible that the wiring from the 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 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.
