7. To alternate the weak signal of RDS station with a strong one

When pressing the AF button briefly, 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. (When AF flash on LCD, it will search for RDS
station. If AF and TP flash on LCD, it can only search for traffic announcement station).
During FM mode, when AF is on, SEEK, (SCAN), AUTO-MEMORY function can only
receive and save RDS program.
When pressing and holding the AF button, AF mode is converted to REGION ON/OFF
mode.
REGIONAL MODE ON:
AF switching or PI SEEK is implemented to the station which have all PI codes are
same as current station.(PI CODE is checked when AF CHECK in progress)
REGIONAL MODE OFF:
The regional code in the format of PI code is ignored when AF switching or PI SEEK
is implemented.(PI CODE and COVERAGE AREA is not checked when AF CHECK
in progress)

8. To tune for a station with the traffic announce ment

A) When press the button, it is activated as TA mode on or 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:

1) If the unit is in disc mode, it will switch to radio mode temporarily.

2) 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.

3) 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.
When TA is ON, traffic program identification code is not received during specified
time.
B) When pressed and held, EON TA LOCAL/ EON TA DISTANCE mode is selected.
The purpose of this mode is to reduce unwanted interference caused by EON TA
switching due to weak signal strength, resulting in the radio being switched back to
the current tuned station, or being muted.

1) EONTA LOCAL mode:
When the field strength level of EON linked stations is below the threshold level,
the radio will not switch to that station, avoiding unnecessary interference.
When EONTA LOCAL mode is selected, EONTA LO on numeric display is indicated
for a few seconds.

2) EONTA DISTANCE mode:
EON TA switching will be determined by the information of the current station. When
EONTA DISTANCE mode is selected, EONTA DX on numeric display is indicated for
a few seconds.
