About CD-R/CD-R/W discs:  
In addition to commercially-recorded audio CD's, this unit can play CD-R and  
CD-R/W discs. In some cases, particularly when recorded on older CD burners,  
some CD-R and CD-R/W discs may not play. Also, whenever you are recording  
a CD for playback in this receiver, it is recommended that you record at 24x or  
slower speed for CD-R and 4x or slower for CD-R/W to achieve higher signal  
quality and better playback performance.  
Press the >>| or |<< button and hold to skip forwards or backwards, release  
to resume normal playback.  
8.SEL(MENU) BUTTON AND VOLUME UP ( + )/ DN ( - ) KONB  
a) Press the SEL button briefly, it is activated as selecting each mode of E. VOL.  
-> VOLUME ->BASS ->TREBLE -> BALANCE -> FADER ->  
When selecting a desired audio mode, rotate the VOL knob to adjust the  
audio effect.  
In each mode, the waiting time is about 5 seconds, and when the waiting time  
is over, it returns to the last display mode of tuner or CD mode.  
The control mode of E.VOL is operated with following numeric display.  
- VOL: (MIN)00, 01,......46, 47(MAX).  
1. To keep the disc clean:  
Do not attach any sticker or adhesive tape on the disc.  
Handle the disc by its edge to keep the disc clean and do not touch the surface.  
Before playing a disc, wipe it off with a clean, dust-free cleaning cloth.  
Wipe the disc outwards from the disc center.  
2. When one has already been inserted. Doing so may damage the unit. Insert a disc  
with labeled surface up, or it will damage the unit.  
- BASS/TRE: -07, -06,...,00,...+06,+07  
- BAL: 0LR9, 1LR9, ..., 9LR9,..., 9LR1, 9LR0  
- FAD: 0FR9,1FR9, ..., 9FR9,..., 9FR1, 9FR0  
3. Do not expose the disc to direct sunlight or nearby heat sources such as heating  
vents, caliduct which can cause the disc to warp.  
b) When pressed longer 2 seconds, it show the time then it is activated as  
cyclical mode of following functions for users selection.  
->TA(ON/OFF) -> AF(ON/OFF) -> TA (ALARM/SEEK) ->PI (SOUND/MUTE)  
->RETUNE (LONG/SHORT)->MASK(DPI/ALL) ->BEEP (ON/OFF)  
-> USER SET(FLAT/CLASSIC/ROCK/POP)->VOL(LAST/DEFA)  
-> EUROPE/AMERICA(in radio mode) ->MONO/STEREO(only for FM mode)  
->LOUD(ON/OFF) ->LOCAL/DX(only for FM mode) ->CLK(ON/OFF)  
Do not leave disc in a car if it is parked in direct sunlight as that will lead to a  
considerable rise in the temperature inside the car.  
4. Do not use any secondhand or rented disc, usually, there is glue on the surface of  
those discs, it will stop the unit working and damage it.  
5. Always store the disc in its case for protection. Scratched up discs will produce poor  
sound performance and cause CD player to skip.  
you can adjust HOUR or MINUTE by rotating  
->CLK(12/24)mode->CLK 0000(  
the VOL knob).  
After selecting the desired mode, rotate the VOL knob to select one setup  
item of the desired mode.  
6. In raining day or wet area, the moisture may form on the disc or the optical parts,  
the playback may not be possible. If moisture forms on the disc, wipe it off with a  
soft cloth.  
1) TA [TRAFFIC ANNOUNCEMENT]  
When TA mode is on(TA is displayed on LCD), it will begin to seek TA station  
and TA SEEK will be displayed on LCD for a while.  
If moisture forms on the optical parts of the unit, allow the unit to sit for about one  
hour with power on.  
When traffic announcement is transmitted:  
7. Do not use solvents such as benzine or thinners. Commercially available cleaners  
or anti-static spray will damage the unit.  
(1)If the unit is in USB or disc mode, it will switch to radio mode temporarily.  
Temporarily switch over to an EON linked station when EON detects a traffic  
announcement on that other program, and TP will be displayed on LCD  
(2)If volume level is below 20, volume level is raised to 20, and returns to its  
previous mode and volume level when the traffic announcement is over.  
(3)If volume is adjusted during traffic announcement, only the traffic  
announcement volume is valid.  
* TA interruption function:  
The current traffic announcement is cancelled by pressing this key. But the  
TA mode will not be off.

2) AF [ALTERNATIVE FREQUENCIES]  
20. SD CARD SLOT  
When you need to play the file in the SD card, insert the SD card into the  
SD card slot. The system will change into the SD mode automatically,  
and then play the first file in the SD.  
When AF switching mode is selected and the state of AF switching mode is  
displayed by AF segment in display.  
Segment off: AF switching mode off.  
Note:  
Segment on: AF switching mode on, and has RDS information.  
Segment flashing: AF switching mode on, but RDS information is not  
received yet.  
When SD card and USB stick are both inserted into their slot or socket, the  
system will change into the playback mode of the latter one.  
When AF switching mode is selected, the radio checks the signal strength of  
AF all the time. The interval of checking time of each AFs depends on the  
signal strength of current station, from a few minute for strong station to a few  
seconds for weak station. Every time that new AF is stronger than current  
station, it switches over to that frequency for very short time, and  
NEW FREQUENCY is displayed for 1-2 seconds. Because the mute time of AF  
switching or checking time is very short, it is almost inaudible in case of  
normal program.  
INSTALLATION METHOD  
This is an anti-theft installation method.  
The main unit wears a METAL MOUNTING SLEEVE.  
Please connect the wiring, eg, the Power supply, the Speakers and the Antenna  
according to the requirements of this Instruction Manual, then install the metal mounting  
sleeve into the car as per the diagram illustrated below.  
During FM mode, when AF is on, SEEK, (SCAN), AUTO-MEMORY function can  
only receive and save RDS program.  
To properly fix the metal mounting  
sleeve, bend the tabs of the sleeve  
against the DASH BOARD with a  
screwdriver.  
To raise the anti-skip capability of the unit,  
please ensure the metal support strap is  
connected firmly to the car chassis.  
3) TA SEEK/TA ALARM:  
METAL  
SUPPORT STRAP  
TA SEEK mode: when newly tuned station does not receive TP information for  
5 seconds, the radio retunes to next station which has a different PI to the last  
station, but has the TP information.  
When TP information gets lost at the current station for retune time which is  
set by RETUNE SHORT(60 seconds) or RETUNE LONG(90 seconds), the  
radio starts to retune to next same PI station. When same PI station does not  
receive in 1 cyclic search, the radio retunes to next station with TP information.  
TA ALARM mode: when this mode is selected, any automatic retune mode is  
not activated. Only double beep sound(ALARM) will be heard.  
When newly tuned station does not have TP information for 5 seconds, beeps  
are sounded.  
UNIT CHASSIS  
PLASTIC TRIM RING  
DASHBOARD  
METAL MOUNTING SLEEVE  
FRONT PANEL  
To remove the CD player out of the mounting sleeve,  
insert the two supplied keys into the left and right side  
slots of the chassis at the same time.  
When TP information gets lost at the current station for retune time, the beep  
sound will be heard.  
When newly tuned station has no RDS signal, PI SEEK is suppressed .  
4) PI SOUND/ PI MUTE:  
NOTE  
PI SOUND mode: if a car cruises between buildings that could cause  
reflecting signals, a phenomenon may occur, due to different PI codes being  
received from the same AF source. when different PI sounds (DIP) are heard  
occassionally, this will happen for less than 1 second.  
PI MUTE mode: under above same situation, a mute sound will be heard for  
less than1second.  
Remove the two screws that protect  
the CD player during transportation  
before operating the player.  
Before installing and operating  
the CD player, remove the metal  
mounting sleeve illustrated by  
the arrows.  
To attach the removable faceplate, insert the  
right side of the faceplate into the right of the  
CD player chassis first. Then push the left side  
of the faceplate into the chassis until you hear  
it click.  
5) RETUNE L / RETUNE S:  
The initial time of automatic TA search or PI SEARCH mode is selected.  
When PI information is not received for retune interval , the radio starts to  
retune to next same PI station.  
When same PI station does not receive 1 cyclic search, the radio goes to last  
station and waits for 4-5 minutes until PI code is received.  
RETUNE L mode: selected as 90 seconds.  
RETUNE S mode: selected as 60 seconds.
