First Steps
b Precautions for reading
• If the BL-N90/N90K communicate with the communication unit wirelessly, then the
barcode will not be read.
(A low-pitched beep will sound twice.)
• Be sure to aim the laser to scan the entire length of the barcode.
{ Correct scan × Incorrect scan
• Only shine the laser light on one barcode at a time. Scanning multiple barcodes at once
can lead to scan errors, or barcodes being scanned out of order.
× Incorrect scan
• Depending on the laser reflection, interior lighting, or barcode label angle, light reflected
from the label may be partially reflected, resulting in scan errors.
In such situations, adjust the label and laser angle or distance.
• When scanning an RSS Stacked barcode, aim the laser and scan from the top of the
barcode to the bottom, or from the bottom to the top.
b Caution when using the BL-N9UB/N9V
When using the BL-N9UB/N9V, barcode data read by the BL-N90/N90K is treated as data
entered through the keyboard. In this way, data may be input directly into the running
application, without the need for special drivers.
When using the BL-N9UB/N9V, please note the following:
• Do not try to read a barcode while pressing down a key on the computer's keyboard. Do
not press a key while receiving the data. Data input will not be read correctly.
• If the computer has multiple language settings, make sure that the input mode is set for
single-byte alphanumeric characters.
