I am very sorry, because our assistant engineer gave me the test report form file records. I check the data can meet the limit in that test report. After I saw your attachment and checked the original draft writing data. I found the submitted test report to CCS in page 15 and 16 is wrong. Our assistant engineer has corrected this error after submitted application. So, when I checked the test report data can meet the limit. Please see the attachment is correct test data in page 15 & 16. Please check. Thank you very much.

Type of emission is 161KF3E for headset. 1. To adjust GT/MT Switch, and Gain Control, Simply push down both snap locks on the sides of battery cover and flip it backwards to expose the adjustment panel. 2. Before power on, ascertain if same channel was set up for both receiver and micrphone. If not adjust to same channel accordingly. 3.

This site has been fully described in a report submitted to your office, and accepted in a letter dated Feb. 10, 2000. ETC Report No.:ET91R-06-083-04 Sheet 4 of 24 Sheets FCC ID.:JEBQF-20 3. OUTPUT POWER MEASUREMENT 3.1 Provision Applicable According to § 74.861(e)(1)(i), the output power shall not exceed 50 milliwatts. 3.2 Measurement Procedure 1. Setup the configuration per figure 1 and 2 for frequencies measured below and above 1 GHz respectively, adjusting the input voltage to produce the maximum power as measured in chapter 3. 2. Adjust the analyzer for each frequency measured in chapter 6 on a 1 MHz frequency span and 100 kHz resolution bandwidth. 3. The search antenna is to be raised and lowered over a range from 1 to 4 meters in horizontally polarized orientation. Position the highness when the highest value is indicated on spectrum analyzer, then change the orientation of EUT on test table over a range from 0 。 to 360 。 , and record the highest value indicated on spectrum analyzer as reference value. 4. Repeat step 3 until all frequencies need to be measured were complete. 5. Repeat step 4 with search antenna in vertical polarized orientations. 6. Replace the EUT with a tuned dipole antenna (horn antenna for above 1 GHz) relative to each frequency in horizontally polarized orientation and as the same polarized orientation with search antenna. Connect the tuned dipole antenna to a standard signal generator (SG) via a low loss cable. Power on the SG and tune the right frequency in measuring as well as set SG at a appreciated output level. Rise and lower the search antenna to get the highest value on spectrum analyzer, and then hold this position. Adjust the SG output to get a identical value derived from step 3 on spectrum analyzer. Record this value for result calculated. 7. Repeat step 6 until all frequencies need to be measured were complete. 8. Repeat step 7 with both dipole antenna (horn antenna for above 1 GHz) and search antenna in vertical polarized orientations.
