• The sensitivity of the D Beam controller will change depending 

on the amount of light in the vicinity of the unit. If it does not 
function as you expect, adjust the sensitivity as appropriate for 
the brightness of your location.

 

Add

 

• In order to provide the highest possible image quality, the 

ATELIER uses a TFT liquid crystal display. Due to the nature of a 
TFT liquid crystal display, the screen may contain pixels that fail 
to light or that remain constantly lit, but please be aware that 
this is not a malfunction or defect.

• (For AT-900C)

If you play at an excessive volume, a protection circuit will 
operate, causing the sound from the speakers to be temporarily 
muted. If this occurs, please lower the volume.

• Floppy disks contain a plastic disk with a thin coating of 

magnetic storage medium. Microscopic precision is required to 
enable storage of large amounts of data on such a small 
surface area. To preserve their integrity, please observe the 
following when handling floppy disks:
• Never touch the magnetic medium inside the disk.
• Do not use or store floppy disks in dirty or dusty areas.
• Do not subject floppy disks to temperature extremes (e.g., 

direct sunlight in an enclosed vehicle). Recommended 
temperature range: 10–50 degrees C (50–122 degrees F).

• Do not expose floppy disks to strong magnetic fields, 

such as those generated by loudspeakers.

 

652

 

• Floppy disks have a “write protect” tab which can protect the 

disk from accidental erasure. It is recommended that the tab be 
kept in the PROTECT position, and moved to the WRITE 
position only when you wish to write new data onto the disk.

• The identification label should be firmly affixed to the disk. 

Should the label come loose while the disk is in the drive, it 
may be difficult to remove the disk.

 

654

 

• Store all disks in a safe place to avoid damaging them, and to 

protect them from dust, dirt, and other hazards. By using a 
dirty or dust-ridden disk, you risk damaging the disk, as well as 
causing the disk drive to malfunction.

• When connecting USB memory, firmly insert it all the way in.

 

705

 

• Do not touch the pins of the USB memory connector, or allow 

them to become dirty.

 

708

 

• USB memory is made using high-precision electronic 

components, so please observe the following points when 
handling it.
• To prevent damage from static electrical charges, 

discharge any static electricity that might be present in 
your body before handling USB memory.

• Do not touch the terminals with your fingers or any metal 

object.

• Do not bend or drop USB memory, or subject it to strong 

impact.

• Do not leave USB memory in direct sunlight or in 

locations such as a closed-up automobile. (Storage 
temperature: 0–50 degrees C)

• Do not allow USB memory to become wet.
• Do not disassemble or modify USB memory.

 

Addition

 

• When connecting USB memory, position it horizontally with the 

external memory connector and insert it without using excessive 
force. The external memory connector may be damaged if you 
use excessive force when inserting USB memory.

 

Addition

 

• Do not insert anything other than USB memory (e.g., wire, 

coins, other types of device) into the external memory 
connector. Doing so will damage the external memory 
connector.

 

Addition

 

• Do not apply excessive force to the connected USB memory.

 

Addition

 

• If you will not be using USB memory for an extended period of 

time, close the USB memory cover.

 

Add

 

• When handling the discs, please observe the following.

• Do not touch the encoded surface of the disc.
• Do not use in dusty areas.
• Do not leave the disc in direct sunlight or an enclosed 

vehicle.

• Avoid touching or scratching the shiny underside (encoded 

surface) of the disc. Damaged or dirty CD-ROM discs may not 
be read properly. Keep your discs clean using a commercially 
available CD cleaner.

 

Add

outside. Do not wipe along circumference.

 

Add

 

• Do not use benzine, record cleaner spray or solvents of any 

kind.

 

Add

 

• Do not bend the disc. Bending discs may prevent proper 

reading and writing of data, and may further result in 
malfunction.
