On safety

Do not operate the unit while driving, cycling or operating any motorized vehicle.

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, remove the battery and 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.

  • Listening with this unit at high volume may affect your hearing.

  • For traffic safety, do not use this unit while driving or cycling.

  • Do not use this unit at a place where the inability to hear surrounding sounds may present a danger.

  • 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.

On maintenance

To clean the exterior, use a soft cloth slightly moistened in water. Then use a soft dry cloth to wipe the exterior. Do not use alcohol, benzine or thinner.


If you have questions about any of the precautions listed above or have any problems concerning your unit, please consult your nearest Sony dealer.

Backup recommendations

To avoid potential risk of data loss caused by accidental operation or malfunction of the IC recorder, we recommend that you save a backup copy of your recorded files to a computer, etc.

Notes on the Bluetooth function

  • Bluetooth wireless technology allows connection at a distance of up to about 10 m. However, the effective range may vary depending on obstructions (people, metals, walls, etc.) or signal status.

  • Because Bluetooth and wireless LAN (IEEE802.11b/g) devices use the same frequency (2.4 GHz), signal interference may occur, resulting in communication speed decrease, noise, or inability to connect, if Bluetooth communications are used near a wireless LAN device. In such cases, take the following measures.

    • Perform Bluetooth communications at least 10 m away from the wireless LAN device when connecting your IC recorder and a Bluetooth device.

    • Place your IC recorder and the Bluetooth device as close together as possible.

    • Turn off the wireless LAN device when performing Bluetooth communications within about 10 m of a wireless LAN device.

  • Radio waves emitted from a Bluetooth device may affect the operation of equipment such as electronic medical devices. Turn off your IC recorder and other Bluetooth devices in the following locations as failure to do so may cause an accident.

    • In hospitals, near priority seats on trains, in airplanes, in places such as gasoline stations where flammable gases are present, near automatic doors or fire alarms.

  • If the operation indicator on the remote control keeps flashing and the remote control seems not working, you may be able to solve this by having your IC recorder and the remote control registered with each other once again.

    For detailed instructions on the device registration, see Registering the remote control with the IC recorder.
