First Steps
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
• 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".
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)
