1)TA ON/OFF
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:
a) If the unit is in SD, USB or disc mode, it will switch to radio mode temporarily.
b) 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.
c) 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.
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 (ON/OFF)
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 second.
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(90 seconds) or RETUNE LONG(150 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.

double beep sound(ALARM) 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) RETURN L / RETURN 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.
RETURN L mode: selected as 150 seconds.
RETURN S mode: selected as 90 seconds.
6) MASK DPI/MASK ALL:
MASK DPI mode: masks only the AF which has different PI.
MASK ALL mode: masks the AF which has different PI and NO RDS signal with high field strength.

CARE FOR USING CD'S:
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 come 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 one has already been inserted. Doing so 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
