Safety Precautions

■ Safety Precautions on Laser Apparatus

WARNING

Use of controls or adjustments or performunce of procedures other than those
specified herein may result in hazardous radiation exposure.

The “Hand-held Barcode Reader HR-51 Series” employs a visible red semiconductor laser
for its light source. HR-51 has a wavelength of 650 nm and is classified as a Class 2 laser
under IEC standard (IEC60825-1: “Safety of Laser Products”).

Model HR-51

Wavelength 650nm

Maximum output 1.0mW

Class CLASS 2 (IEC60825-1)

• Do not directly stare into the laser beams or specularly reflected light. Doing

so may result in serious eye injury. Do not direct laser beams towards a human
body intentionally although laser beams will not cause damage even if it
strikes exposed skin.

• Never disassemble HR-51. HR-51 is not equipped with a mechanism to stop

laser emission when disassembled. If HR-51 is disassembled, laser beams

WARNING

emitted from HR-51 may cause eye injury.

• Before cleaning the transmitter/receiver part of laser scanner, be sure to stop

the emission of laser beams. Otherwise, exposure to the laser may cause eye
injury.

• Be careful of the light path of laser beams.

Be especially careful of the specularly reflected light.
Do not install HR-51 in such a way that the laser beam passes at eye height
when operating HR-51.

Operating Precautions

■ Precautions on use

• Do not disassemble or modify this unit. Doing so may lead to product fail-

ure.

• This unit is a precision instrument. Dropping the unit or subjecting it to

shock may cause damage. Take enough care when carrying or using this
unit.

• Locate cables as far as possible from high-voltage lines and power lines.

Otherwise, generated noise may cause product failure or operation error.

• Do not hold the unit by its cable when carrying. The HR-51 may strike the

wall and may be damaged. Also due to the stress on the cables, the wires
may be broken.

• Be sure to use the supplied AC adaptor or optional AC adaptor for HR-

UC51. Using other AC adaptors than these may result in fire, electric shock
or product failures.

• Be sure to periodically clean the power connection part of AC adaptor con-

nected to HR-UC51 as it tends to catch dust. Tracking phenomenon may
result in fire. Also, disconnect the AC adaptor from the outlet if not using a
long period of time.

CAUTION

• When recharging HR-51 on HR-UC51, be sure to check no foreign objects

are attached to the recharge terminal. Foreign objects may cause fire.

■ Environments for use

Do not use in the following locations. Product failure or mechanical error may
occur.

• Locations where the ambient temperature is beyond specified range

• Locations where the ambient humidity is beyond specified range

• Locations where the unit is exposed to direct sunlight

• High-temperature locations such as inside a closed car

• Locations where condensation occurs due to the rapid humidity change

• Locations where there are corrosive gas or combustible gas

• Locations where there is a large amount of airborne dust, salt, iron, and

greasy fumes

• 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

Precautions for using the built-in rechargeable battery

HR-51 contains the built-in lithium ion rechargeable battery. Observe the following precau­tions for proper use.
On disposal, follow the disposal procedure specified by each local government.

•

Stop the recharging process if recharging does not finish even after the speci­fied recharge time.
The built-in rechargeable battery may become hot, explode or cause fire.

• If there is leak or abnormal smell from the built-in rechargeable battery, keep it

DANGER

WARNING

CAUTION

away from fire immediately.
The battery electrolyte may catch fire, resulting in explosion and ignition.

• Never put it into the fire. The explosion of built-in rechargeable battery may

lead to a serious accident.

• Never put it into the water. The chemical reaction of the built-in rechargeable

battery may lead to an accident.

• In the event that the leaked liquid comes into the eye, do not wipe it. Clean it

immediately with clean water instead and go to the eye specialist. If the eye is
left untreated, eye damage may result.

• In the event the liquid leaked from the built-in rechargeable battery is attached

to the skin, wash it immediately with clean water. Otherwise, skin irritation may
occur.

•

Do not leave or use it in a heated car, under the scorching sun or at high­humidity locations. The built-in rechargeable battery may become hot or cause
fire. Also, the battery life may become short and the performance may deterio­rate.

• Recharge and use the built-in battery in the temperature environment of –5 to

140 degree. If it is used in other temperature environments than this, the built­in rechargeable battery may be hot or damaged. Also, the life become short
and the performance may deteriorate.

• Never use other rechargers than the specified one. Product failure may occur.

Wireless communication

HR-51 and HR-UC51 contain the built-in wireless device based on the Bluetooth wireless
technology.

Never disassemble or modify HR-51 and HR-UC51 as those conducts are pro-

CAUTION

■ Cautions for wireless communication

• If the product is used near a wireless LAN device with the same frequency band as that
of HR-51 and HR-UC51, radio wave interference may occur and the communication
speed becomes slow or communication may become impossible.

• The communication may be impossible near equipment using the same frequency band
of electric wave as that of HR-51 and HR-UC51, such as microwave oven, industrial
heating equipment and medical high-frequency equipment.

• Communication may be impossible in the following locations

- Locations near metallic objects or where there is much metallic powder

- Locations surrounded by a metallic wall

- Locations where the unit is subject to strong vibration

• Communication-possible distance is approx. 10 m, however, depending on the environ­ment for use, communication may be impossible. Make sure to check the communica­tion condition before introduction.

• With the frequency band for HR-51 and HR-UC51, premise radio stations (with license
required) and specified low power radio station (with license not required) for identifying
mobile objects used for industrial, scientific and medical equipment or product lines in
factory are operating.

• Before using HR-51 and HR-UC51, be sure to check that premise radio stations and
specified low power radio stations are not operating in the vicinity.

• If radio wave interference occurs from HR-51 and HR-UC51 against premise radio sta­tions for identifying mobile objects, stop the electric wave generation, contact the follow­ing address and consult to take necessary measures (i.e. setting a partition) to avoid
interference.

• If radio wave interference occur from HR-51 and HR-UC51 against specified low power
radio stations for identifying mobile objects or other problems occur, contact the follow­ing address.

again using either of the methods below.

• Read “Connection-ON barcode”.

• Read the readable barcode when “Automatic connection after reading the barcode”

is “Enable”.

• When “Connection on/cut by pressing down the trigger key” is “Enable”, press down
the trigger key for the set time for “Trigger key pressing-down time: Connection ON”.

• Read the BD address of HR-UC51.
