FCC Warning
This device complies with Part 15 of the FCC Rules. Operation is
subject to the following two conditions:
(1) This device may not cause harmful interference, and (2) this device
must accept any interference received, including interference that may
cause undesired operation.
NOTE 1: 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.
NOTE 2: Any changes or modifications to this unit not expressly
approved by the party responsible for compliance could void the user's
authority to operate the equipment.

The foll owing two wavef orms a lso illustrat e existence of
electromagnetic interference in the environment:
Interference source analysis
(1) Power adapter: laptop power supply, display power supply, LED light
power supply, surveillance camera power supply, electric car charger, power
supply of other electric equipment.
(2) Card reader with the same frequency band: access card reader, desktop
card issuer.
(3) Motor equipment.
Troubleshooting
Turn on the Noise Detection function, and switch off the power of the
interference source one by one. At the same time, observe changes of the
interface waveform, in order to determine the interference source.

6. Troubleshooting of FAQs
When using the TPAD20 M, you may experience problems, such as distance
decrease or intermittent reading of a single tag, instability of reading multiple labels,
slow reading, or large number changes, etc. When these problems occur, there may be
electromagnetic interference in the environment rather than the machine performance
issue. Interference source can be judged and investigated by the "noise detection"
