The pages that have been changed are Page 1, 3, 4, 5. There were some errors in the report. Per your request of 5/21/01; 1. Please correct the 731 form to read 9K8F3E which is the correct emission designator. I’ve also corrected Page 1 of the test report to reflect this change. 2. I’ve uploaded better internal photographs. 3. This device is a GMRS device. The correct frequency range on the report (Page 1) and on the 731 form should be: 462.550-462.7250 MHz. I’ve corrected Page 1 of the report. Please correct the 731 form. 4a. The tuneup procedure is correct. The 731 form was in error. The correct output power is 2.0 Watts (High) and 0.5 Watts (Low). On the page that you read 4.43 and 1.5 as the listed ERP (Page 1) – that is actually the dc input power, not the output power. 4b. The conducted output power is 2.0 Watts (High), 0.5 Watts (Low). Please refer to page 4 of the corrected test report. Please correct the 731 form. 4c. The antenna has negative gain. 4d. The ERP is 2.0 Watts (High), 0.5 Watts (Low) 4e. The field strength level of the fundamental is: 130.44 dBuV/m (High) 124.94 dBuV/m (Low) 5. They have included statements in their manual (please refer to Page 7) regarding the distance between the user and the antenna. Should you have any further questions, please advise.

The conducted output power and the ERP are the same because the antenna gain is 0 db. 2. We have done the calculation for SAR and I have attached that calculation for our review.
