INTEGRATOR AND HOST REQUIREMENTS
Authorization requirements
TWN4 MultiTech 3 LEGIC M BLE 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 BLE has
been integrated.
In particular, the host integrator installing TWN4 MultiTech 3 LEGIC M BLE 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 BLE 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 BLE 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 BLE:
Contains FCC IDs: WP5TWN4F14, QOQ11
Contains transmitter modules IC: 7948A-TWN4F14, 5123A-11
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.
