1

Hold down the trigger switch on the paired BL-N90/N90K for about 10 seconds to enable
sleep mode.

A beep will sound as sleep mode is enabled. ( page 1-6)
During sleep mode, the wireless connection is disabled, causing the blue LED on the
communication unit to blink. This connection must be disabled in order for the communication
unit to pair with another BL-N90/N90K.

2 Use the second BL-N90/N90K to scan the barcode of the communication unit.
3 Scan the initialization barcode. ( page 2-15)

2-7 Reading a Barcode

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

2

First Steps

• 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.

communication. Please use in the following environment.

b Transmission range and surrounding conditions

The BL-N90/N90K and the communication unit have a line-of-sight range of approximately
10 meters.
However, obstacles placed between the BL-N90/N90K and the communication unit, such
as concrete or metal, may interrupt the wireless connection. Please use the device in an
environment free of these obstacles.

First Steps

Also read the notes regarding wireless communication ( Page 3).

b When the wireless connection is interrupted

The following occur when the wireless connection is interrupted:

• The blue LED on the BL-N90/N90K flashes

• The blue LED on the communication unit flashes.

Once a connection can be established again, the BL-N90/N90K and communication unit
automatically reconnect.

• Reconnection may take between 10 to 30 seconds.

• During this time, barcodes cannot be read.

(A low-pitched beep will sound twice.)
