Locating a specific track Automatic Music Sensor (AMS)
During playback, press either side of (SEEK/AMS) momentarily for each track you want to skip.
To locate preceding tracks To locate succeeding tracks
If you use personalised labels, they will always take priority over the original CD TEXT information when such information is displayed.
Tip The Motion Display mode can be turned off. (See Changing the sound and display settings on page 24).
Locating a specific point in a track Manual Search
During playback, press and hold either side of (SEEK/AMS). Release when you have found the desired point.

To return to normal play mode, select BANKOFF in step 2.
Repeat step 4 to set PLAY or SKIP for all the tracks. Press (MENU) twice. The unit returns to normal CD play mode.
Notes You can set PLAY and SKIP for up to 24 tracks. You cannot set SKIP for all the tracks on a CD.
Memorising stations automatically

Best Tuning Memory (BTM)

The unit selects the stations with the strongest signals and memorises them in the order of their frequencies. You can store up to 6 stations on each band (FM1, FM2, FM3, MW, and LW). Caution When tuning in stations while driving, use Best Tuning Memory to prevent accidents.
Memorising only the desired stations
You can preset up to 18 FM stations (6 each for FM1, FM2, and FM3), up to 6 MW stations, and up to 6 LW stations in the order of your choice.
Press (SOURCE) repeatedly to select the tuner. Press (MODE) repeatedly to select the band. Press either side of (SEEK/AMS) to tune in the station that you want to store on the number button. Press the desired number button ((1) to (6)) for two seconds until MEM appears. The number button indication appears in the display.
Press (SOURCE) repeatedly to select the tuner. Each time you press (SOURCE), the source changes as follows:

B Tuner B CD* B MD

* If the corresponding optional equipment is not connected, this item will not appear.
Note If you try to store another station on the same number button, the previously stored station will be erased.
Press (MODE) repeatedly to select the band. Each time you press (MODE), the band changes as follows:
B FM1 B FM2 B FM3 LW b MW b
Press (MENU), then press either side of (DISC/PRST) repeatedly until BTM appears. Press (ENTER). The unit stores stations in the order of their frequencies on the number buttons. A beep sounds when the setting is stored.
Notes The unit does not store stations with weak signals. If only a few stations can be received, some number buttons will retain their former setting. When a number is indicated in the display, the unit starts storing stations from the one currently displayed. If an MD is not in the unit, only the tuner band appears even if you press (SOURCE).
Receiving the memorised stations
Press (SOURCE) repeatedly to select the tuner. Press (MODE) repeatedly to select the band. Press the number button ((1) to (6)) on which the desired station is stored.
If FM stereo reception is poor Monaural Mode
During radio reception, press (MENU), then press either side of (DISC/PRST) repeatedly until MONO-OFF appears. Press the (+) side of (SEEK/AMS) until MONO-ON appears. The sound improves, but becomes monaural (ST disappears). Press (ENTER).
Tip Press either side of (DISC/PRST) to receive the stations in the order they are stored in the memory (Preset Search Function).
To return to normal mode, select MONO-OFF in step 2.

If you cannot tune in a preset station
Press either side of (SEEK/AMS) to search for the station (automatic tuning). Scanning stops when the unit receives a station. Press either side of (SEEK/AMS) repeatedly until the desired station is received.
Note If the automatic tuning stops too frequently, press (MENU), then press either side of (DISC/PRST) repeatedly until LOCAL (local seek mode) is displayed. Then press the (+) side of (SEEK/AMS) to select LOCAL-ON. Press (ENTER). Only the stations with relatively strong signals will be tuned in. Tips When you select the LOCAL-ON setting, L.SEEK appears while the unit is searching for a station. If you know the frequency of the station you want to listen to, press and hold either side of (SEEK/AMS) until the desired frequency appears (manual tuning).
Overview of the RDS function
Radio Data System (RDS) is a broadcasting service that allows FM stations to send additional digital information along with the regular radio programme signal. Your car stereo offers you a variety of services. Here are just a few: retuning the same programme automatically, listening to traffic announcements, and locating a station by programme type.
Notes Depending on the country or region, not all of the RDS functions are available. RDS may not work properly if the signal strength is weak or if the station you are tuned to is not transmitting RDS data.
Tip The Motion Display mode can be turned off. (See Changing the sound and display settings on page 24.) Note NO NAME appears if the received station does not transmit RDS data.
Retuning the same programme automatically
Alternative Frequencies (AF)
The Alternative Frequencies (AF) function automatically selects and retunes the station with the strongest signal in a network. By using this function, you can continuously listen to the same programme during a longdistance drive without having to retune the station manually.
Frequencies change automatically. 96.0MHz

98.5MHz

The name of the current station lights up in the display. Select an FM station (page 16). When you tune in an FM station that transmits RDS data, the station name appears in the display.

Station

102.5MHz
Select an FM station (page 16). Press (AF) repeatedly until AF-ON appears. The unit starts searching for an alternative station with a stronger signal in the same network.

Note The * indication means that an RDS station is being received.
Changing the displayed item
Each time you press (DSPL/PTY), the item changes as follows:
Station Name (Frequency) y PTY data
Notes When there is no alternative station in the area and you do not need to search for an alternative station, turn the AF function off by pressing (AF) repeatedly until AF-OFF appears. When NO AF and the station name flash alternately, it means that the unit cannot find an alternative station in the network. If the station name starts flashing after selecting a station with the AF function on, this indicates that no alternative frequency is available. Press either side of (SEEK/AMS) while the station name is flashing (within eight seconds). The unit starts searching for another frequency with the same PI (Programme Identification) data (PI SEEK appears and no sound is heard). If the unit cannot find another frequency, NO PI appears, and the unit returns to the previously selected frequency.
Local link function (United Kingdom only)
The Local Link function lets you select other local stations in the area, even if they are not stored on your number buttons.
Press a number button that has a local station stored on it. Within five seconds, press the number button of the local station again. Repeat this procedure until the desired local station is received.
Listening to a regional programme
The REG-ON (regional on) function lets you stay tuned to a regional programme without being switched to another regional station. (Note that you must turn the AF function on.) The unit is factory preset to REG-ON, but if you want to turn off the function, do the following.
Listening to traffic announcements
The Traffic Announcement (TA) and Traffic Programme (TP) data lets you automatically tune in an FM station that is broadcasting traffic announcements even if you are listening to other programme sources. Press (TA) repeatedly until TA-ON appears. The unit starts searching for traffic information stations. TP appears in the display when the unit finds a station broadcasting traffic announcements. When the traffic announcement starts, TA flashes. The flashing stops when the traffic announcement is over.
Tip If the traffic announcement starts while you are listening to another programme source, the unit automatically switches to the announcement and goes back to the original source when the announcement is over.
During radio reception, press (MENU), then press either side of (DISC/PRST) repeatedly until REG appears. Press the (+) side of (SEEK/AMS) until REG-OFF appears. Press (ENTER). Note that selecting REG-OFF might cause the unit to switch to another regional station within the same network.
To return to regional on, select REG-ON in step 2.

Note This function does not work in the United Kingdom and in some other areas.
Notes NO TP flashes for five seconds if the received station does not broadcast traffic announcements. Then, the unit starts searching for a station that broadcasts it. When EON appears with TP in the display, the current station makes use of broadcast traffic announcement of other stations in the same network.
Presetting the RDS stations with the AF and TA data
When you preset RDS stations, the unit stores each stations data as well as its frequency, so you dont have to turn on the AF or TA function every time you tune in the preset station. You can select a different setting (AF, TA, or both) for individual preset stations, or the same setting for all preset stations.
To cancel the current traffic announcement
Press (TA), (SOURCE) or (MODE). To cancel all traffic announcements, turn off the function by pressing (TA) until TAOFF appears.
Presetting the same setting for all preset stations
Presetting the volume of traffic announcements
You can preset the volume level of the traffic announcements beforehand so you wont miss the announcement. When a traffic announcement starts, the volume will be automatically adjusted to the preset level.
Select an FM band (page 15). Press (AF) and/or (TA) to select AF-ON and/or TA-ON. Note that selecting AF-OFF or TA-OFF stores not only RDS stations, but also non-RDS stations. Press (MENU), then press either side of (DISC/PRST) repeatedly until BTM appears. Press the (+) side of (SEEK/AMS) until BTM flashes. Press (ENTER).
Turn the volume control dial to adjust the desired volume level. Press (TA) for two seconds. TA appears and the setting is stored.
Receiving emergency announcements
If an emergency announcement comes in while you are listening to the radio, the programme will be automatically switched to it. If you are listening to a source other than the radio, the emergency announcements will be heard if you set AF or TA to ON. The unit will then automatically switch to these announcements no matter which source you are listening to at the time.
Presetting different settings for each preset station
Select an FM band, and tune in the desired station (page 16). Press (AF) and/or (TA) to select AF-ON and/or TA-ON. Press the desired number button until MEM appears. Repeat from step 1 to preset other stations.
