Troubleshooting

The recorded file is noisy and is hard to understand.

• Ambient noise is recorded as well as human voices. If you apply the Clear Voice function (“Clear Voice 1” or “Clear Voice 2,”) to the playback audio, ambient noise in all frequency bands (noise from projectors or air conditioners, etc.) will be reduced to make human voices distinctive, and you will hear human voices more clearly. While playback with the built-in speaker or playback of the files in “ Music” is in progress, however, the Clear Voice function does not work.

The recorded file is noisy and you want to record with less noise.

• With the Recording Filter function (“NCF(Noise Cut)” or “LCF(Low Cut)”), you can reduce noise in the recordings. Additionally, you can use the Scene Select function to change some recording settings, including the recording mode and the sensitivity level of the built-in microphone, at once by selecting one of the recording scenes

A rustling noise is recorded.

• If you accidentally touch your IC recorder or let an object come in contact with it while recording is in progress, rustling noises may be recorded. Keep your hand away from the IC recorder until you finish recording.

A buzzing or humming noise is recorded.

• A buzzing or humming noise may be recorded if your IC recorder is placed near an AC power source, a fluorescent lamp, or a mobile phone during recording or playback. Keep the IC recorder away from such devices when recording.

Noise is recorded when you use an external microphone (not supplied) for recording.

• The plug of the connected external microphone is dirty. Clean the plug.

You hear noise when using headphones (not supplied) for playback.

• The plug of the connected headphones is dirty. Clean the plug

The volume of the audio you recorded from an external device is low or you hear squeaking noises when you listen to the audio via the built-in speaker.

• If you record audio from a monaural external device that is connected to your IC recorder with a stereo connection cable, playing the recorded files may sound low in volume or make squeaking noises when you listen to the audio via the built-in speaker. This is because the left and right audio signal output is reversed in phase, and does not indicate a malfunction. Be sure to use an audio cable with a monaural plug to record audio from a monaural external device.

You hear noise during playback even with the Clear Voice function turned on.

• While playback with the built-in speaker or playback of the files in “ Music” is in progress, the Clear Voice function does not work.
