On handling

• Do not leave the unit in a location near heat sources, or in a place subject to direct sunlight, excessive dust or mechanical shock.
• Should any solid object or liquid fall into the unit, have the unit checked by qualified personnel before operating it any further.
• When using your IC recorder, remember to follow the precautions below in order to avoid warping the cabinet or causing the IC recorder to malfunction.
  • Do not sit down with the IC recorder in your back pocket.
  • Do not put your IC recorder into a bag with the headphones/earphones cord wrapped around it and subject the bag to strong impact.

• Be careful not to allow water to splash on the unit. The unit is not waterproof. In particular, be careful in the following situations.

  • When you have the unit in your pocket and go to the bathroom, etc.

    When you bend down, the unit may drop into the water and may get wet.

  • When you use the unit in an environment where the unit is exposed to rain, snow, or humidity.
  • In circumstances where you get sweaty. If you touch the unit with wet hands or if you put the unit in the pocket of sweaty clothes, the unit may get wet.
• You may feel pain in your ears if you use the headphones when the ambient air is very dry. This is not because of a malfunction of the headphones, but because of static electricity accumulated in your body. You can reduce static electricity by wearing non-synthetic clothes that prevent the emergence of static electricity.

On noise

• Noise may be heard when the unit is placed near an AC power source, a fluorescent lamp or a mobile phone during recording or playback.
• Noise may be recorded when an object, such as your finger, etc., rubs or scratches the unit during recording.
