z General Cautions
• Do not modify the BL-N70 series, or use it in any way other than described in the
specifications.
• When the BL-N70 series is used in combination with other devices, functions and
performance may be degraded, depending on the operating conditions and
surrounding environment.

Safety Precautions
z Safety Precautions on Laser Apparatus
The "Hand-held Laser Barcode Reader BL-N70 Series" employs a visible red
semiconductor laser for its light source. This laser has a wavelength of 650 nm and is
classified as a Class 1 laser under IEC60825-1 (Safety of laser products). Do not
disassemble or modify the BL-N70 series.
Use of controls or adjustments or performance of procedures other than those

specified herein may result in hazardous radiation exposure. Exposure to laser
light may cause damage to eyes.
•
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
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.

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
