1) TA[TRAFFIC ANNOUNCEMENT]
When TAmode is on(TAis displayed on LCD), it will begin to seek TAstation
and TASEEK 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, onlythe traffic
announcement volume is valid.

CARE FOR USING CD'S:
1. To keep the disc clean:
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
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.
. 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.
About CD-R/CD-R/W discs:
In addition to commercially-recorded audio CD's, thisunit can play CD-R and
CD-R/W discs. In somecases, particularly when recorded onolder CD burners,
some CD-R and CD-R/W discs may not play.Also, whenever you are recording
a CD for playback in thisreceiver, it is recommendedthat 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.

2) AF [ALTERNATIVE FREQUENCIES]
When AF switching mode is selectedand thestateofAFswitching mode is
displayed byAF 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.
WhenAF 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
secondsfor weak station. Every time that newAF 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 timeis very short, it is almost inaudible in case of
normal program.
During FM mode, whenAF is on, SEEK, (SCAN),AUTO-MEMORYfunction can
only receive and save RDS program.
3)TASEEK/TAALARM:
TASEEK mode: when newly tuned station does notreceiveTPinformation 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
receivein 1 cyclicsearch, the radio retunes tonext station withTP 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 stationdoesnot have TP information for 5 seconds, beeps
are sounded.
When TP information gets lost at the current station for retune time, the beep
soundwillbeheard.
When newly tuned stationhas 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 sameAF 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 TAsearch 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.
