To System Designers:
When introducing the QK31 series of scanners in those systems that could affect human lives (e.g.,
medicines management system), develop applications carefully through redundancy and safety design
which avoids the feasibility of affecting human lives even if a data error occurs.
Wrong handling of the scanner could result in a heat, smoke, or scanner failure. Be sure to observe the following.
Never bring any metals into contact with the terminals in connectors.
Doing so could produce a large current through the scanner, resulting in heat or fire, as well as damage
to the scanner.
Keep the scanner away from water.
Failure to do so could cause fire or electrical shock.
Never use the scanner on the line voltage other than the specified level.
Doing so could cause the scanner to break or burn.
Do not use the scanner where any inflammable gases may be emitted.
Doing so could cause fire.
Do not scratch, modify, bend, twist, pull, or heat the interface cable. Do not place heavy material on the
cable or allow the cable to get pressed under heavy material.
Doing so could break the cable, resulting in a fire.
Do not subject the scanning window of the scanner to direct sunlight for extended periods.
Doing so could damage the scanner, resulting in a fire.
If smoke, abnormal odors or noises come from the scanner, immediately switch off the host computer,
unplug the interface cable, and contact your nearest dealer.
Failure to do so could cause fire or electrical shock.
If foreign material or water gets into the scanner, immediately unplug the interface cable, and contact
your nearest dealer.
Failure to do so could cause fire or electrical shock.
If you drop the scanner so as to affect the operation or damage its housing, switch off the host computer,
unplug the interface cable, and contact your nearest dealer.
Failure to do so could cause fire or electrical shock.
