First Steps

Rechargeable Batteries for the BL-N90/N90K

The BL-N90/N90K sounds an alarm when the battery is low.

When using the scanner, be mindful of the alarm and always maintain a charge.

bBattery low alarm

When the BL-N90/N90K battery level gets low, the following alarms are sounded.

•Each time a barcode is read, a beep sounds two times

bContinuous use capacity

The following table offers estimates of how long the BL-N90/N90K can be used

continuously on a full charge.

Since the BL-N90/N90K scanner and the communication unit are continuously communicating

wirelessly, battery power is depleted even when the BL-N90/N90K is not in use.

•

When not in use, it is recommended that you set the BL-N90/N90K in the communication unit.

•When not using the device for long periods, enabling sleep mode interrupts the wireless

communication, thereby saving battery power.

bCharging time

A fully depleted (no charge) battery takes approximately 4 hours to fully charge.

Reference

•If the "Trigger" switch is pressed but the laser light is short, or if the laser does

not light when reading a barcode, the battery may be low.

•If the laser does not light even when pressing the "Trigger" switch, then the

battery is completely depleted.

Establishing a Connection

The BL-N90/N90K and the communication unit communicate as a pair. This section describes

how to establish a connection between the BL-N90/N90K and the communication unit.

Procedure

1Press the "Trigger" switch to activate the laser.

2Scan the barcode attached to the communication unit.

After 10 to 30 seconds, a connection will be established. Once a connection is established, the

devices will be in the following state:

• The blue LED on the scanner is lit.

• The blue LED on the communication unit is lit.

Note Perform the following operation with the communication unit connected to your

computer ( page 2-5).

Note

The following symptoms indicate that a connection is not established.

•The blue LED on the scanner is flashing

•The blue LED on the communication unit is flashing

At this stage, perform the following steps.

Note that even when using multiple BL-N90/N90K scanners, each scanner can only

communicate with its pair communication unit ( page 2-14).

Notes About Establishing a Connection Between the

Scanner and the Communication Unit

bReading a barcode

The BL-N90/N90K cannot read a barcode unless a connection has been established with

the communication unit.

(A beep will sound twice.)

bUsing multiple BL-N90/N90K barcode readers

•Only the connected barcode reader and communication unit pair can communicate with

one another.

•If multiple BL-N90/N90K barcode readers scan the same communication unit barcode,

only the first barcode reader to scan the communication unit can communicate with it.

To ch ange the pairing, follow the procedure below entitled "Swapping out the BL-N90/

N90K".

bSwapping out the BL-N90/N90K

When swapping one BL-N90/N90K barcode reader for another, follow the procedure

below.

Procedure

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.

2Use the second BL-N90/N90K to scan the barcode of the communication unit.

3Scan the initialization barcode. ( page 2-15)

2-7 Reading a Barcode

This section describes the basic barcode scanning operations.

Scanning a Barcode

The BL-N90/N90K is able to read barcodes when it is connected wirelessly to the communication unit.

The wireless connection can be verified by checking that the blue LED on the communication

unit is lit ( page 1-6).

1Press the "Trigger" switch to activate the laser.

As the laser is activated, the blue LED on the BL-N90/N90K lights up .

2Aim the laser to cover the entire barcode.

3Once scanning is complete, the white LED lights up , a beep will sound once ,

and data is transmitted to your computer.

First Steps

bPrecautions 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.

bCaution 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.

First Steps

2-8 Wireless Connection Environment

The BL-N90/N90K and the communication unit use Bluetooth Version 1.2 for their wireless

communication. Please use in the following environment.

bTransmission 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.

bWhen 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.)
