2-4 Charging the BL-N90/N90K
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.
b Battery 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
• 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.
Reference
First Steps
• If the laser does not light even when pressing the "Trigger" switch, then the
battery is completely depleted.
b Continuous use capacity
The following table offers estimates of how long the BL-N90/N90K can be used
continuously on a full charge.
Usage Condition
Estimated Continuous Use Length
One scan every 10 seconds
Approx. 10 hours
One scan every 5 seconds
Approx. 8.5 hours
Idle with full charge *
Approx. 12 hours
Sleep mode with full charge *
Approx. 54 hours
* 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.
Note
• The continuous use times listed above are estimates. Actual times may vary.
• If the continuous use times decrease remarkably, then it is time to replace the
batteries. Contact your nearest KEYENCE office.
b Charging time
A fully depleted (no charge) battery takes approximately 4 hours to fully charge.

Notes About Establishing a Connection Between the
Scanner and the Communication Unit
b Reading 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.)
b Using multiple BL-N90/N90K barcode readers
First Steps
• 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 change the pairing, follow the procedure below entitled "Swapping out the BL-N90/
N90K".
b Swapping out the BL-N90/N90K
When swapping one BL-N90/N90K barcode reader for another, follow the procedure
below.
Procedure
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)

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.
× Incorrect scan
{ Correct scan
× 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.
2-17
First Steps
• 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.
