FEDERAL COMMUNICATIONS COMMISSION INTERFERENCE STATEMENT
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.
This device complies with part 15 of the FCC Rules. Operation is subject to the following two conditions:
This device may not cause harmful interference.
This device must accept any interference received, including interference that may cause
undesired operation.
CAUTION:
Any changes or modifications not expressly approved by the party responsible for compliance could void
the user’s authority to operate the equipment.
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.
Information for the OEMs and Integrators
The OEM integrator has to be aware not to provide information to the end user regarding how to install or
remove this RF module in the user manual of the end product. The user manual which is provided by OE
M integrators for end users must include the following information in a prominent location.
To comply with FCC RF exposure compliance requirements, the antenna used for this
transmitter must be installed to provide a separation distance of at least 20 cm from
all persons and must not be co- located or operating in conjunction with any other antenna or transmitter.
If the end product integrating this module is going to be operated in 13.56MHz frequency range, the warni
ng statement in the user manual of the end product should include the restriction of operating this device
in indoor could void the user’s authority to operate the equipment.

4.9 Reset and download concept
To enter reset there are 2 ways:
- Pulling VEN low (Hard Power Down state)
- If V
monitor is enabled: lowering V
BAT
below the monitor threshold (monitor mode, if VEN
BAT
is kept above 1.1 V)This reset mode can be left if PbF is enabled when the field is high
enough (RF field detected) to enter PbF mode.
To get out of reset, there are 2 ways:
- Pulling VEN high with V
above V
BAT
monitor threshold if enabled
BAT
- Entering a field strong enough to power the IC
