FCC Part 15 Class B Device
NOTE:
This equipment has been tested and found to comply with the limits for a Class B
digital device, pursuant to Part 15 of the FCC Rules. These limits are designed to provide
reasonable protection against harmful interference in a residential installation. This
equipment generates, uses and can radiate radio frequency energy and, if not installed
and used in accordance with the instructions, may cause harmful interference to radio
communications. However, there is no guarantee that interference will not occur in a
particular installation. If this equipment does cause harmful interference to radio or
television reception, which can be determined by turning the equipment off and on, the
user is encouraged to try to correct the interference by one or more of the following
measures:
Reorient or relocate the receiving antenna.
Increase the separation between the equipment and receiver.
Connect the equipment into an outlet on a circuit different from that to which the
receiver is connected.
Consult the dealer or an experienced radio/TV technician for help.
12.4.2.
EN55022 – Emissions
The eXtendo® family of thermal printers are class “B” appliances, and comply to applicable
Class “B” standards, when installed in a properly grounded housing with appropriate
conductive shielding.
When operating the printer from a DC building power supply, or when the DC power cable
or data cable exceeds 3 meters in length, appropriate EMI filters must be used.
12.4.3.
EN55024 – Electromagnetic Susceptibility
Electrostatic discharges and burst effects may cause short printing interruptions, but the
automatic recovery function of the printer will restore it to its original state.
Additional action regarding lightning and overvoltage protection will be needed if cables
and wires are installed outside of a building.
However, this standard can be met only if original units, components, and cables are used
and the installation instructions are respected and followed completely.
External interference caused by ESD or EMI can temporarily cause corrupted printing or
data loss.
