(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:

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.
