•Do not look directly into laser light or reflected laser light from a mirrored surface. Otherwise, eye injury may result. Laser light will not cause damage if it strikes exposed skin, but laser light should not deliberately be aimed towards a human body.
•Do not disassemble the BL-N70 series. The BL-N70 series does not automatically stop emitting the laser when the reader is disassembled. Therefore, if someone disassembles the reader, he/she may be exposed to
|
WARNING |
the laser beam and may suffer eye injury. |
•Be sure to stop the laser emission before cleaning the portion of the laser scanner where laser light is generated and received (emitter/receiver). Otherwise, exposure to the laser may cause eye injury.
•Be careful of the path of the laser beam.
Be especially careful of reflected laser light from a mirrored surface.
Do not use the BL-N70 series where the path of the laser beam is at the same height as that of the human eye.

Operating Precautions
z Operations
•Do not use a voltage other than 5V DC with the BL-N70 series. Doing so may lead to breakdown on the unit. When using the dedicated power sources BLU1, BL-U2, or N-42 use a power supply within the appropriate range for each communication unit.
•Be sure to turn the power off to devices attached to the BL-N70 series when you plug or unplug the cables. Failure to do so may cause damage to the BLN70 series.
•Do not disassemble or modify the BL-N70 series. Doing so may lead to breakdown on the unit.
•Keep the cables away from high-tension cables or power sources. Otherwise, noise could cause malfunctions or accidents.
•The BL-N70 series passes the drop impact resistance test, but take care not to expose the unit to excessive shock.
•Do not hold the BL-N70 series by its cable. The unit may become damaged.
z Cleaning
•Do not allow water, oil, dust, or other foreign substance to stick to the laser emitter/receiver. This may cause read errors. When the BL-N70 series becomes dirty or stained, clean the surface using an eyeglass cleaning cloth or a soft cloth that has been dampened with a specialty cleaner for plastics that can handle acrylic.
(Substances such as ethanol can make acrylics cloudy.)
z Operation Environment/Conditions
CAUTION To use the BL-N70 series correctly and safely, avoid installing it in the following locations. Failure to do so may cause fire, electric shock, damage, accidents, or malfunctions.
•Locations where the BL-N70 series is exposed to direct sunlight
•Locations where the ambient temperature drops below 0°C or exceeds +40°C
•Locations where the ambient humidity goes outside of the range of 35 to 85%RH
•Locations where the temperature changes rapidly, causing condensation
•Locations where there are flammable or corrosive gases
•Locations where there is a large amount of airborne dust, salt, iron, and greasy fumes
•Locations where the ambient lighting exceeds the regulation range
•Locations where the unit may be directly subjected to vibration or impact
•Locations where water, oil or chemicals may splash onto the unit
•Locations where a strong magnetic or electric field is generated.
z Procedures during Malfunction
Turn off the dedicated power source immediately in the following cases. Using the unit in abnormal conditions could cause fire, electric shock, or accidents. Contact your nearest KEYENCE office (listed at the end of the manual) for repair if :
•chemicals, debris, or liquids, including water, enter the BL-N70.
•the BL-N70 is damaged.
•smoke or abnormal odors are emitted from the BL-N70 series.
z For Obtaining the UL Certification
Use the NEC Class 2 output power supply for UL application.

Using Basic Operations
This section explains basic methods for operating the barcode reader.
Reading a barcode
Point the laser emitter/receiver towards the barcode and press the trigger switch about 100 mm (4") from the barcode.
•The green status LED lights up when the barcode has been read correctly. A buzzer sounds after the reading is complete or after read data is sent.
(The buzzer can be disabled. see 
page 4-14)
• Barcode data is sent to the connected computer or other device.
z Precautions for reading
Adjust the scan line so it completely covers the barcode from end to end.
Correct scan method
Incorrect scan method
You cannot specify which barcode to read.

Barcodes Scanning

Scanning
The laser turns on when the trigger switch on the BL-N70 is pressed. While holding the trigger switch, bring the BL-N70 scanner towards the barcode to a distance that complies with the reading range characteristics on 
page A-3. Ensure that the entire code fits within the scan line.
•Only shine the laser light on one barcode at a time. To enter two or more barcodes, read each barcode separately one after the other.
Note
•Do not shine the laser light on the barcode label at an angle. The reader may not be able to read the barcode.
z Trigger modes
There are three modes that can be used when pressing the trigger switch. Choose the most appropriate mode for the situation (
page 3-4).
•Trigger switch mode – Laser OFF until trigger is depressed. Barcodes scanned only while trigger is depressed
•Continuous emission mode – Laser always ON. Barcodes scanned only while trigger is depressed
•Continuous reading mode – Laser always ON. Barcodes always scanned. No trigger required.
z Data Send Format
Read data is sent to the connected computer or other device.
• For the format of the sent data, see 
page 3-5.
•For information about the communication protocols when using BL-N70RE/RKE, see
page 3-7.
