The following item(s) need(s) to be resolved before the review can be continued: 1. The Confidentiality Request Letter submitted for this application requests that the Tune-Up Procedure be held confidential. There is no exhibit for Tune-Up Procedure. Please change the Confidentiality Request Letter exhibit to remove the reference to the Tune-Up Procedure exhibit. Please see the updated Confidentiality Letter. 2. The Application Form indicated that this device was being filed for Equipment Class DXC, but the test report shows that this is a 15.247 Digital Modulation device which is equipment Class DTS. Please confirm that it is OK for me to change this Equipment Class on the application form to be DTS. It is OK. Please change this equipment class on the application form to be DTS. 3. Please provide more technical information about the operation of this device. The manual indicates that there is a linking process, and can communicate with up to 8 receiver units. The Test report indicates that this device uses DQPSK modulation. Please provide a better technical description which better describes the modulation scheme, communication with multiple receivers, linking process, how to change channels, number of channels, etc. Please see the product specification. (HOP Mode : The sender unit able to connector with same model receiver by one to one , the number of connection up to 8 unit in sequence . device connection change by press < Hop > Switch one time .) 4. The table on page 11 of the test report indicates that the 6dB bandwidth of this device is 11300 kHz, where the test plots on pages 12 and 13 show 1130 kHz bandwidth. Please correct this test table. Also, please include the AC Conducted Emissions plot in the report. Please see P11 and P36-37 in the updated report. The items indicated above must be submitted before processing can continue on the above referenced application. Failure to provide the requested information within 30 days of the original e-mail date may result in application dismissal and forfeiture of the filing fee. Also, please note that partial responses increase processing time and should not be submitted.
