•When connecting a USB memory, position it horizontally with the
BK-5’s USB MEMORY port and insert it without using excessive
force. The USB MEMORY port may be damaged if you use excessive
force when inserting a USB memory.
• Do not insert anything other than a USB memory (e.g., wire, coins,
other types of device) into the USB MEMORY port. Doing so will
damage the BK-5’s USB MEMORY port.
• Never connect your USB memory to the BK-5 via a USB hub.
• Do not connect or disconnect a USB drive while it is being read
from, or written to (i.e., while the USB flash access indicator
blinks).
Handling CDs
• Avoid touching or scratching the shiny underside (encoded sur-
face) of the disc. Damaged or dirty CD discs may not be read prop-
erly. Keep your discs clean using a commercially available CD
cleaner.
