NOTICE
WARNING
•Do not use a voltage other than that described in the specifications with
the SR-750 Series. Doing so may damage to the unit.
•The SR-750 Series employs 2 power connection methods, which are 24 V
DC supply and supply from PoE power supply devices. When connecting
the SR-750 Series to the power source, be sure to use only one of these
methods. Using both power sources simultaneously may cause damage
to the units.
•Be sure to turn off the power to devices attached to the SR-750 Series
when you plug in or unplug the cables.
Failure to do so may cause damage to the SR-750 Series.
•Do not disassemble or modify the SR-750 Series. Doing so may damage to
the unit.
•Place cables as far away as possible from high-voltage lines and power
lines. Otherwise, electrical noise can be generated that may cause product
failure or malfunction.
•The SR-750 Series is a precision instrument. Do not impact or drop the
instrument. Pay particular attention when transporting or installing the
unit.
•Do not hold the unit by its cable when carrying. The units may become
damaged if the cables are disconnected or the units strike each other.
•Do not allow water, oil, dust, or other foreign substances to stick to the
scanner. This may cause read errors.
Use a soft, dry cloth to wipe any substance from the scanner. (Do not use
a cloth dipped in alcohol or other cleaning substance.)
