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.
