Why will my Rio Karma 

not power on?

• Confirm  the  LOCK/UNLOCK switch on the player is set to UNLOCK. The player 

will not power on if LOCK/UNLOCK is in the LOCK position. Switch LOCK/

UNLOCK to the UNLOCK position and press POWER to turn the Rio Karma on. If 

the Karma still does not power on, the battery may be completely dead.

What type of files can I 

play with the Rio Karma?

• You can play FLAC, MP3, Ogg Vorbis, and WMA audio files on the Rio Karma.

Can I add FLAC, MP3, Ogg 

Vorbis, and WMA files to 

the player at the same 

time?

• Yes. You can play FLAC, MP3, Ogg Vorbis, and WMA audio content. They can be 

mixed together.

What are the differences 

between FLAC, MP3, Ogg 

Vorbis, and WMA files?

• Ogg Vorbis and WMA files are generally half as large as comparable sounding MP3 

files. Because Ogg Vorbis and WMA uses smaller file sizes, you can store more 

sound in less space on CDs or hard drives. The WMA format is exclusive to 

Windows-based computers. Unlike MP3, OGG, and WMA formats, the FLAC 

format is lossless and creates perfect duplicates when ripping and encoding CD 

audio. Perfect sound requires a great deal of space and FLAC files are typically 

four to eight times larger than 128kbps MP3, OGG, or WMA files. 

Rio Music manager can encode audio tracks in FLAC, OGG and WMA formats by 

default and MP3 with an upgrade.
