I, the undersigned, hereby declare that

1. The device does not use the provisions of 47CFR 15.323 (c) (6), random waiting mechanism
   is not used in this system.

2. The provisions of 47CFR 15.323 (c) (10) and 47CFR 15.323 (c) (11) are not used to extend
   the range of spectrum occupied over space or time for the purpose of denying fair
   access to spectrum to other devices.

3. Only the Wireless Mic unit will act as the initiating device, which will initiate the
   establishment of the duplex connection.

4. The device complies with the provisions of 47CFR 15.319(f). The device shall
   automatically discontinue transmission in case of either absence of information to
   transmit or operational failure. These provisions are not intended to preclude
   transmission of control and signaling information or use of repetitive codes used by certain
   digital technologies to complete frame or burst intervals. The following table explains the
   reaction of device in case of either absence of information to transmit or operational failure
   after a connection of its companion device is established.

       Circumstances                                                             Reaction of Wireless mic
  1    Switch-off companion device                                                           NA
  2    On hook by companion device                                                           NA
  3    Remove power from companion device                                                    A
  4    Switch-off device                                                                     NA
  5    On hook device                                                                        C
  6    Remove power from device                                                              NA
 A     – Connection is terminated and, transmission ceases.
 B     –   Connection is terminated but device transmits control or signaling information.
 C     –   Connection is terminated but companion device transmits control or signaling information.
 NA    –   Not applicable represents the device does not contain a hook switch or a power off switch.


5. ML of Wireless mic declared by manufacturer are 30dBm.

If you have questions or need further information, please contact the undersigned.
