How long does Anti-Shock last?

With MP3 files, Anti-Shock lasts 120 seconds. With Audio CD, it does 40 seconds.

Why does mechanism noise occur?

When loading a CD or searching a Music, CD Pick-up makes noise moving at high speed. This is not malfunction. But if you hear mechanism noise through earphones or occurs excessive noise, get customer service.

Does backup CD reduce the lifetime of the Lens?

There is no connection between a blank CD and the lifetime of the lens.

Why doesn't the player recognize a CD burnt at high speed?

There are some CD-RWs burnt at a high speed. The others have no problem with reading CD. In general, it is recommended to record the CD with 1~2 level lower than the highest burning speed.

FAQ

Using general batteries:

Open the battery cover on the inside of the player.

Insert batteries(AA size x 2ea) matching + and - and close the battery cover.

Manganese batteries are not recommended as they run out quickly. For optimum playback time, Alkaline batteries are recommended.

insert new batteries.

How do I make a CD from a Language Study tape?

To convert the tape's information into CD requires many items, including: Sound Edit program (Goldwave, Cooledit), stereo cable to connect each side, and a player to play the Tape. Connect Stereo cable to earphone output on the player and Line in socket of Computer Sound Card or Mic socket; then record the sound using the Sound Edit Program.

I recorded a CD but it contains less than 20 songs.

When you burn a CD with MP3 file, you need to confirm that it is recorded in DATA format. It means the CD is burnt in Audio CD format, it can record just less than 20 songs.

The player can’t read songs and I get 'No disc' message.

CD readability depends on several factors:

1. CD-Media

2. The Burning/Recording Speed

3. The CD surface When you burn a CD, burning speed does matter as well as CD surface. When you burn a CD at a high speed, the data writing may not be reliable. In that case, it is recommended to burn a CD at a lower speed or to use brand media.

Can I add songs to the CD I already burned?

Using multi-session or packet writing allows you to add songs to the CD.

FAQ

How do I download MP3 files?

You need to record MP3 files onto a CD-R or CD-RW disc to play in the iMP-50 player.

In general, there are two kinds of blank CDs. CD-R (CD Recordable): Recordable but not reusable. CD-RW (CD-ReWriteable) : Recordable and can be used again after erasing.

There are several ways to burn a CD. A CD is burned into session unit (the data is stored from the center of the CD).

Single session: Close session after burning once. Multi session: Do not close session after burning that allows you to burn again.

The burning way of deleting/recording data in CD like a hard disc is called packet writing. CD-R is used single-session / multi-session and CD-RW is used packet writing. iRiver player can recognize pack-written CD-RW.

What do I need to burn MP3 files?

You need a CD recorder, recording software program, and blank CD. For details, refer to the “SUPPORT” at iRiver's homepage.

RECORDING

FAQ

3029

The sound cuts out when the player skips.

If the player is shaken in a sudden or violent manner, or shaken excessively, skipping may occur. Under normal circumstances, skipping will not occur. Please carry and handle the player under normal circumstances (i.e., without excessive shaking).

It takes a long time to load a CD.

Using Multi-sessioned or Packet Written CD may affect the loading time rather than using Single sessioned CD because the data is scattered in the CD. To reduce the loading time, it is recommended you to burn in Single-session. You may contact Customer Service if it takes longer than 1 minute to load a singlesessioned CD or a Standard Audio CD.

It always stops after playing one song.

Check whether the Auto Pause function is ON. If so, turn Auto Pause OFF.

I hear a 'hiccup' sound while the song is playing.

Check the status of the file. What is likely happening is that the file has broken, especially if you hear the same sound in the same spot. In this case, it is recommended you to record the file again or download a different file.

Can I change the playing order?

The iMP-50 supports m3u file lists. Also, the Program function allows you to select your preferred songs.

FAQ

How do I listen to a spot on the track I last listened to?

The iMP-50 provides a RESUME function. Go to Function, General and enter into RESUME menu. You can set Track Time or Track #. The iMP-50 can remember the last 10 CDs you played.

How many playlists can the iMP-50 play?

The iMP-50 can play up to 20 playlists( .m3u)

How many songs can the iMP-50 play?

The iMP-50 can recognize 999 songs and 255 directories with subdirectory.

Does the iMP-50 play ra, wav format?

The playable formats on the iMP-50 are MP3, ASF and WMA files. The ra and wav formats can not be played in this player. Supporting formats such as ra and wav are under consideration in the future.

I don't see the title and it only displays Audio Track.

The iMP-50 can display the information that the song contains. With MP3 files, the tag information may not be correct and with Standard Audio CD, it displays only Audio Track. To see the song title, you need to burn the CD using CD-TEXT function.

PLAYING

FAQ

3231

No Power On

Loading stopped or 'No DISC' displayed on LCD

No Sound or noise is heard

Check whether the batteries have been inserted in proper polarity (+ and -). Check whether the HOLD switch on the player or remote is ON (Switch to OFF position). Check whether the player lid is open. Check whether the batteries ran out.

Check whether the CD is dirty or defective (clean it or change to new CD). Check whether the CD is inserted with the label side up. Check whether dirt are attached in optical lens (remove the dirt with a soft cloth). Check whether moisture condensation has occurred (leave the CD player aside for several hours until the moisture evaporates). Check whether the CD is inserted. Problem may occur due to the characteristic deviation between CD-RW recorder and CD-R/RW disc (burn the disc in low speed). Use packet write disc with full formatting done.

Check whether VOLUME is set to “0”. Connect the earphone plug firmly. Check whether the plug is dirty (clean the plug with a dry and soft cloth). Corrupted MP3, WMA file may have a noise or sound cut off. Excessive jolting may affect MP3, WMA, and audio CD discs to proper playback.

Should any problem continue after you have checked these symptoms, please contact iRiver sales representatives.

TROUBLE SHOOTING

I can't hear ASF file.

There are two kinds of ASF files, Audio and Video. The iMP-50 supports Audio ASF file only.

Is the sound better if I convert an MP3 file into WAV?

There are two groups of audio data, compressed and uncompressed. MP3 is a diminished compression format in the compressed group, meaning it is not possible to create the original audio file 100%, partly due to the fact that there are frequencies missing. Once it is lost, there is no way to recover the lost part.

What kind of media can the iMP-50 support?

Standard Audio CD (8Cm, 12 Cm), CD-R, CD-RW DATA CD with MP3, ASF and WMA. The iMP-50 also supports Mixed CD (Data Track + Audio Track), CD-Extra (Audio Track + Data Track), Multi-sessioned and packet written CD.

What is VBR?

VBR is "Variable Bit Rate". Some MP3 encoders support VBR. When enabled, the compressor will use a bit rate that will fit the actual passage. If it is a complex part, having much more variation in the sound, it will use a high bit rate. If there is less variation in sound, it will use a lower bit rate. Usually, the average bit rate will not be as high as a same-quality MP3 with CBR (Constant Bit Rate). However, there is shortcoming that it's hard to keep track of the actual position that may not be favorable when studying language.

On Headphones and Earphones

Road Safety

Do not use headphones/earphones while driving, cycling, or operating any motorized vehicle. It may create a traffic hazard and is illegal in some areas. It can also be potentially dangerous to play your headsets at high volume while walking, especially at pedestrian crossings. You should exercise extreme caution or discontinue use in potentially hazardous situations.

Preventing hearing damage

Avoid using headphones/earphones at high volume. Hearing experts advise against listening to continuous, loud and extended play. If you experience a ringing in your ears, reduce volume or discontinue use.

Consideration for others

Keep the volume at a moderate level. This will allow you to hear outside sound and to be considerate of the people around you.
