or debris on a disc or in the CD slot,  
remove it with a clean cloth to avoid  
pushing it into the player mechanism.  
To remove dirt from the faceplate, use  
a clean cloth lightly moistened with  
filtered water. If the unit is splashed  
with water, wipe it off with such a clean  
damp cloth before the water has dried  
to avoid an accumulation of salts on  
the face of the unit.

If properly installed, this unit will meet  
the IPX5 Waterproof standard. Please  
note that this does NOT mean the unit  
is submersible, but will resist being  
sprayed and splashed as might occur  
in a normal boat cabin.

CD playback  
MP3 disc playback  
Please follow these general instructions to  
play a music CD disc. On the column to  
the right, you will find instructions for using  
MP3 discs.  
When you insert an MP3 (or WMA) disc,  
the player will begin playback from the first  
track in the directory.  
However, MP3 discs can contain many  
more tracks than audio CD’s, so you may  
wish to search for a particular track to play.  
There are two search methods available.  
Please note that only some of these  
functions are available on the remote control.  
Loading a disc  
Press the RELEASE button to lower the  
front panel. This will expose the disc slot.  
TRACK SEARCH MODE  
In disc playback mode, press the BAND  
button once. The LCD will display the word  
“TRACK.”  
To begin searching, press SELECT or the  
UP/DOWN button. Then press and hold  
the UP or DOWN button to locate the  
desired track, and press SELECT to begin  
playback.  
Gently insert disc until it is drawn in  
by player mechanism.  
NAVIGATE THE CURRENT FOLDER  
Gently insert a disc into the disc slot until  
you feel it being drawn in by the player  
mechanism. If there is already a disc in the  
player, first press EJECT to eject it and  
remove it.  
This mode permits you to navigate the file  
directory present on the disc.  
To enter this mode, press BAND twice. The  
display will display “NAVIGA.” Press  
SELECT to enter this mode.  
Playing a disc  
The disc will begin playing automatically. If  
you wish to pause playback, press  
PLAY/PAUSE, and press again to resume  
playback.  
Use the UP and DOWN buttons to move  
up and down the directory of folders and  
files on the disc. To enter a subfolder ,  
highlight it and press SELECT. You will then  
see the directory of that subfolder and can  
select tracks within it. So play a track,  
highlight it and push SELECT.  
To start playback from the first track, press  
PRESET 1. To skipahead or back ten tracks  
on the disc, press the +10 or -10 button.  
Intro Scan function  
The Intro Scan function is a convenient way  
to find a particular track. Press this button  
and the player will play the first few seconds  
of a song, and then skip to the next song  
and play a few seconds of that song. This  
process continues until you press the INTRO  
button again, and the player will continue  
playing that song.  
VIEWING MP3 FILE INFORMATION  
Since many MP3 files are tagged with  
Music/Artist/Album (ID3-TAG) information,  
you can see this as a list by pressing AS/PS  
repeatedly.  
The information will appear as a scrolling  
display, including the folder and file name  
as well as the ID3-TAG information.  
Repeating a track  
To keep repeating the same track, press  
the REPEAT button. To cancel the repeat  
function, press again.  
Please note that if this information is not  
present in ID3-TAG version 1.0 or 2.0 format,  
it will not be displayed.  
Random play  
Pressing the RANDOM button will cause  
the player to play all the songs on the current  
disc in random order. Press again to cancel  
this function.

RDS Radio functions  
The RDS (Radio Data System) is a digital  
information system created by the European  
Broadcast Union (EBU).  
RDS EON function setting  
The RDS EON system extends the  
functionality of the TA sensing to a wider  
range of traffic announcements from both  
local and national sources. It also allows the  
unit to interrupt disc playback with these  
announcements. In addition, it will play these  
announcements (at normal listening level)  
even if the audio has been muted.  
This system “piggy-backs” a variety of  
information services onto normal FM  
broadcasts. This information can only be  
decoded by a radio with RDS decoding, like  
this model.  
The three main RDS functions are described  
below:  
(To set this level, see instructions on page  
11 for setting V-PGM level).  
AF/REG (Alternate Frequency)  
To enable the EON function, press and hold  
the SCAN button. Press again to disable it.  
When this mode is enabled by pressing and  
holding the MO/ST•AF button, the radio will  
continuously monitor the signal strength of  
the broadcast you are listening to and if it  
finds the same network broadcast on a  
different frequency which is stronger, it will  
automatically switch to the stronger signal.  
With EON enabled, when a traffic  
announcement is broadcast, the radio will  
switch automatically to TA mode, and “TP”  
(Traffic Program) will be displayed.  
Regional mode setting  
In the SELECT menu (see page 11 in this  
manual) you can choose to turn on or off the  
REG (regional mode) subfunction within AF  
mode. The default mode is OFF.  
Although the AF button can sense if one  
station on a network is stronger than another,  
it will not confirm that the actual program  
being broadcast is the same unless you turn  
ON the REG mode.  
TA (Traffic Announcement)  
Many FM stations offer traffic  
announcements in addition to their regular  
programming.  
If you enable the TA function by pressing  
the TA button, when this station broadcasts  
a traffic advisory, the radio’s RDS tuner will  
automatically interrupt the regular program  
and play the alert. When the alert is finished,  
normal play of the broadcast will resume.  
The TA function will also interrupt CD and  
MP3 playback temporarily if the EON feature  
has been enabled (see below).  
There are some other settings for TA  
behavior that you can change. See the  
SELECT instructions on page 11 for more  
information.
