    LASER SAFETY The following information is provided to comply with the rules imposed by international authorities and refers to the correct use of the DS4800 scanner. Standard Regulations This scanner utilizes a low-power laser diode. Although staring directly at the laser beam momentarily causes no known biological damage, avoid staring at the beam as one would with any very strong light source, such as the sun.

  • Page 7: Fcc Compliance

    This product is intended to be installed by Qualified Personnel only. This accessory device is intended to be supplied by a UL Listed or CSA Certified Power Unit with «Class 2» or LPS power source, which supplies power directly to the scanner via the 25- pin connector.

  • Page 30 All scanners are typically located far away from each other and they use a dedicated presence sensor. At the end of each reading phase, each scanner transmits its own data message to the host. Thanks to ID-NET™, data collection among readers is accomplished at a high speed without the need of an external multiplexing device.
