the antennas connected to the PCI Express Mini Cards and all persons.

ii) FCC ID location

At the rear of your Lenovo computer, you will find an indicator label of the

format “Contains Transmitter Module: FCC ID XXXX”, where XXXX represents
the FCC ID that corresponds to your preinstalled Wireless LAN module.

iii) Radio Frequency interference requirements:

The devices have been tested and found to comply with the limits for a
Class B digital device pursuant to FCC Part 15 Subpart B. Refer to “Electronic
