15.3. Using the Recording Function (TS-820RC only)
The TS-820RC Central unit is equipped with a recording function, making it possible to create sound source
files by recording conference dialog and the like to a commercially available USB memory device. The unit is
also equipped with internal memory for recording operations, and allows recording even when abnormalities
arise with the USB memory device.
Note
Only recording can be performed by the Central unit. Use a PC to reproduce, delete or copy sound source files.
15.3.1. Notes on use
Important
Avoid removing the USB memory device during recording. If removed, the USB memory device might not
continue to function properly, or data could be lost.
• Avoid simultaneously connecting a USB memory device and PC to the Central unit.
• The USB memory device cannot be formatted by the unit.
• While a PC is connected, neither recording nor internal memory formatting can be performed by the unit.
• Only USB memory devices can be inserted into the USB memory port. Inserting other USB devices could
result in operational failure.
• Move the sound source file created in the USB memory device to a PC or other device without saving it to the
USB memory device.
• When inserting or removing the USB memory device or PC connector, do not apply unreasonable force to the
port. Failure to observe this instruction could lead to failure of the unit or damage to the PC or other devices.
• Ensure that the USB memory device or PC connector is removed when moving the unit from one place to
another. Moving the unit with such devices inserted could cause failure to the unit or damage to the USB
memory device or PC connection port.
• Be sure to replace the dustproof cover over the USB memory port and the PC connection port to prevent dust
or foreign objects from entering the ports when not in use.
• Be sure to back up recorded internal memory sound source data to a PC or other device, as data could be
lost due to the unit’s failure or faulty operation.
15.2.3. Usable USB memory devices
• USB memory device (flash drive) with a capacity of up to 32 GB.
• Compatible with USB 2.0 devices.
• When using a USB memory device with the Central unit for the first time, format it with a PC before using.
Formatting conditions are as follows:
File system:
FAT32
Allocation unit size: At least 4KB
Note
Perform full formatting, not quick formatting.
• Insert the USB memory device into the PC and perform error checking before use.
• Ensure that the USB memory device is ONLY used with the Central unit, and avoid using it for other purposes.
• The Central unit is not compatible with USB memory devices having other specialized functions, such as
security functions.
• There may be cases in which a USB flash drive cannot be used with the TS-820RC, depending on the drive’s
attributes or recording conditions.
