The control mode of E.VOL is operated with following numeric display.

- VOL: (MIN)00, 01,......46, 47(MAX).

- BASS/TRE: -7, -6,...,0,...+6,+7

- BAL: L,I,...,I,...,I,R

After selecting the desired mode, rotate the VOL knob to select one setup

item of the desired mode.

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.

When traffic announcement is transmitted:

(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.

* When TA is on, SEEK, (SCAN), AUTO MEMORY function can be received or

saved only when traffic program identification code has been received.

2) AF [ALTERNATIVE FREQUENCIES]

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.

Segment on: AF switching mode on, and has RDS information.

Segment flashing: AF switching mode on, but RDS information is not

received yet.

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.

During FM mode, when AF is on, SEEK, (SCAN), AUTO-MEMORY function can

only receive and save RDS program.

3) TA SEEK/TA ALARM:

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.

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:

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.

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.

Care When Using Discs:

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.

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 inserting a disc upside down, thus may damage the unit. Insert a disc

with labeled surface up, or it will damage the unit.

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.

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.

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.

If moisture forms on the optical parts of the unit, allow the unit to sit for about one

hour with power on.

7. Do not use solvents such as benzine or thinners. Commercially available cleaners

or anti-static spray will damage the unit.
