Handling the scanner using a laser light
 Some of the scanners use a laser light for indication of the scanner range. Though the intensity of the laser
light is too low to inflict bodily injury, you must observe the following precautions when handling the BHT
equipped with laser light.
1) Never stare into the laser light.
2) Never point the code reading windows at someone’s eyes.
To System Designers
When introducing BHTs in those systems that could affect human lives, develop applications carefully
through redundancy and safety design which avoids the feasibility of affecting human lives even if a
data error occurs.
CAUTION
Handling the BHT
Incorrect handling of the BHT could cause generation of heat and smoke from the BHT, and
malfunction. Be sure to observe the following to use the device correctly.
 When using the hand strap or neck strap, exercise due care to avoid getting them caught in other objects
or entangled in rotating machinery.
Failure to do so could result in accident or injury.
 Do not move your ear close to the speaker while the Buzzer is beeping. Doing so could lead to hearing
difficulty.
 Do not operate the BHT in environments where static electricity can build into significant charges. Doing so
could result in malfunction or mechanical failure.
 Avoid dropping the battery cartridge or letting it undergo any strong shock or impact. Doing so could result
in malfunction or mechanical failure.
 Do not use the BHT near a wireless transmitter such as a ham radio. Doing so could result in malfunction
or mechanical failure.
 Do not touch BHT with oily hands or gloves containing oil such as machine oil and grease. Doing so may
cause the deformation and discoloration of a device.
 This product incorporates a connector for microSD cards. Do not insert anything other than these cards. Do
not insert a card inversely, diagonally and with twisted. If a card is inserted forcibly, this could damage a
card or a connector.
 Do not attach a wet BHT or rechargeable battery cartridge to CU.
 Do not use excessive force when inserting or removing the battery cartridge. Doing so could result in
malfunction or mechanical failure.
 Keep magnetic cards such as a cash card or a credit card away from the BHT. Failure to do so could cause
loss of magnetic data.
