FCC §15.105 (b)
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.
FCC ID: WP5TWN4F14
4.3 IC
This device complies with Industry Canada’s license-exempt RSSs. Operation is subject to the following two conditions:
(1) This device may not cause interference; and

5INTEGRATOR AND HOST REQUIREMENTS
Authorization requirements
TWN4 MultiTech 3 LEGIC M LF HF has been certified as a module and does not need further approval, provided that the module is
used in accordance with the FCC grant conditions and no limitations or usage conditions have been defined by ELATEC. However,
the host manufacturer must ensure that the host device still complies with all applicable regulations after
TWN4 MultiTech 3 LEGIC M LF HF has been integrated.
In particular, the host integrator installing TWN4 MultiTech 3 LEGIC M LF HF into their product must ensure that the final composite
product complies with the FCC requirements by a technical assessment or evaluation to the FCC rules, including the transmitter
operation and should refer to guidance in KDB 996369.
Labeling requirements
Using a permanently affixed label, TWN4 MultiTech 3 LEGIC M LF HF must be labeled with its own FCC and IC identification numbers.
In case this label is not visible anymore after integration of TWN4 MultiTech 3 LEGIC M LF HF in the host device, it is necessary to
bring a label on the host device (on a visible and accessible place) stating the FCC and IC identification numbers of the integrated
TWN4 MultiTech 3 LEGIC M LF HF:
Contains FCC ID: WP5TWN4F14
Contains IC: 7948A-TWN4F14
In case several modules have been integrated into the host device, the label should state all FCC and IC identification numbers of the
integrated modules.
Example: “Contains FCC IDs: XXX-XXXXXXX, YYY-YYYYYYY, ZZZ-ZZZZZZZ”.
Compliance statements
All statements listed in Chapter “Compliance statements” of this integration manual must be also listed in the user manual of the host
device.
Special accessories
Where special accessories such as shielded cables and/or special connectors are required to comply with the emission limits, the
instruction manual shall include appropriate instructions on the first page of the text describing the installation of the device.
Simultaneous transmission
When the host product supports simultaneous-transmission operations the host manufacturer needs to check if there are additional
RF exposure filing requirements due to the simultaneous transmissions. When additional application filing for RF exposure compliance
demonstration is not required (e. g. the RF module in combination with all simultaneously operating transmitters complies with the RF
exposure simultaneous transmission SAR test exclusion requirements), the host manufacturer may do his own evaluation without any
filing, using reasonable engineering judgment and testing for confirming compliance with out-of-band, restricted band, and spurious
emission requirements in the simultaneous-transmission operating modes. If additional filing is required, please contact the person at
ELATEC GmbH responsible for certification of the RF module.
