               DFS client device channel plan and software operational declaration

 Date: 2019-08-08

      We, Getac Technology Corporation, declare that the device, FCC ID: QYL8265VB2, does not
 have Ad Hoc on “non-US frequencies” and/or on“ DFS frequencies“. Also, the client software and
 associated drivers will not initiate any transmission on DFS frequencies without initiation by a master. This
 includes restriction on transmissions for beacons and support for ad-hoc peer-to-peer modes.

 Below is the channel / frequency plan for the device

 Also, on DFS channels, the WLAN driver in the device operates under the control of an AP at all times,
 except when in ad-hoc mode on US non-DFS channels. The device passively scans DFS frequencies until a
 master device is detected. The control of this functionality is not accessible to anyone under any conditions.
 Furthermore, the firmware is protected by a special signature and CRC checksum. Signature and CRC
 checksum will be calculated and verified before firmware upgrade. Unauthorized modification to firmware
 will lead to the failure of verification and thus firmware upgrade will not be allowed.
 Sincerely yours,
