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. 20. SD CARD SLOT When you need to play the file in the SD card, insert the SD card into the SD card slot.
