Reset Function:
A reset is accomplished by holding the Preset 1 button for 3 seconds at unit powered off.
It will display SYS CLR which indicates the system being successfully reset.
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.
Note: It will be necessary to re-enter the radio preset memories and other personal settings as
these will have been erased when the microprocessor was reset. After resetting the player,
ensure all functions are operating correctly.

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 radio to the vehicles electrical system is poor
or that the battery needs recharging.
If the battery and its charging circuit are OK, then rewire the red fused wire of the radio directly
to the positive terminal (+) of the vehicle battery.
Marine accessory shops stock the connector blocks and the 10 Amp cable which may be
necessary for extending the fuse wire connection.
Make sure that the black wire on the wiring harness is connected to a good ground point on the
vehicle. If the chassis of the vehicle is used as a grounding point, make sure that the surface is
scraped clean from the metal before attaching the wire to it.
It is preferable to connect the black ground wire directly to negative terminal (-) of the vehicle
battery.
This model is only suitable for use in vehicles which have a negative ground system,
e. g.. : the negative terminal of the vehicle battery is connected to the chassis.
Before you wire your system, disconnect your vehicle 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 vehicle or preferably to the negative (-) terminal of
the vehicle battery.
