The equipment under test was operated continuously in its normal operating mode for the purpose of the measurements. In order to secure the continuous operation of the device under test, rewiring in the circuit was done by the manufacturer so as to affect its intended operation. The receiving antenna polarized horizontally was varied from 1 to 4 meters and the wooden turntable was rotated through 360 degrees to obtain the highest reading on the field strength meter or on the display of the spectrum analyzer. And also, each emission was to be maximized by changing the orientation of the equipment under test. In order to determining the average value during one pulse train of the radiated power generated from the equipment under test, the encoded wave form in the time domain was used.

For portable device, the EUT was pretested in three orthogonal plans: put on table horizontally, stands vertically and side up vertically. The worst case was chosen for final test. 3.2 Devices for Tested System Device Manufacture Model / FCC ID. Description Wireless Remote Control for Searchlight*

RADIATED EMISSION MEASUREMENT 4.1 Applicable Standard Sheet 7 of 23 Sheets FCC ID: V78TXSL014GO For periodic operation intentional radiator, the radiated emission shall comply with 15.231(b). 4.2 Measurement Procedure A. Preliminary Measurement For Portable Devices For portable devices, the following procedure was performed to determine the maximum emission axis of EUT:

1. With the receiving antenna is H polarization, rotate the EUT in turns with three orthogonal axes to determine the axis of maximum emission. 2. With the receiving antenna is V polarization, rotate the EUT in turns with three orthogonal axes to determine the axis of maximum emission. 3. Compare the results derived from above two steps. So, the axis of maximum emission from EUT was determined and the configuration was used to perform the final measurement. B. Final Measurement 1. Setup the configuration per figure 1 and 2 for frequencies measured below and above 1 GHz respectively. Turn on EUT and make sure that it is in normal function. 2. For emission frequencies measured below 1 GHz, a pre-scan is performed in a shielded chamber to determine the accurate frequencies of higher emissions will be checked on a open test site. As the same purpose, for emission frequencies measured above 1 GHz, a pre-scan also be performed with a 1 meter measuring distance before final test. 3. For emission frequencies measured below and above 1 GHz, set the spectrum analyzer on a 100 kHz and 1 MHz resolution bandwidth respectively for each frequency measured in step 2. 4. 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 360with a speed as slow as possible, and keep the azimuth that highest emission is indicated on the spectrum analyzer. Vary the antenna position again and record the highest value as a final reading. A RF test receiver is also used to confirm emissions measured. ETC Report No.18-12-RBF-011-01 e Sheet 8 of 23 Sheets FCC ID: V78TXSL014GO 5. Repeat step 4 until all frequencies need to be measured were complete. 6. Repeat step 5 with search antenna in vertical polarized orientations. 7. Check the three frequencies of highest emission with varying the placement of cables

(if any) associated with EUT to obtain the worse case and record the result.

Emission frequencies below 30MHz (9kHz - 30MHz) Sheet 14 of 23 Sheets FCC ID: V78TXSL014GO According to exploratory test no any obvious emission were detected from 9kHz to 30MHz. All emissions were greater than 20 dB below the limit. Although these tests were performed other than open area test site, adequate comparison measurements were confirmed against 30 m open are test site. Therefore sufficient tests were made to demonstrate that the alternative site produces results that correlate with the ones of tests made in an open field based on KDB 414788. 4.4 Field Strength Calculation The field strength is calculated by adding the Antenna Factor and Cable Factor, and subtracting the Amplifier Gain (if any) from the measured reading. For the limit is employed average value, therefore the peak value can be transferred to average value by subtracting the duty factor. The basic equation with a sample calculation is as follows:

Peak = Reading + Corrected Factor where Corr. Factor = Antenna Factor + Cable Factor - Amplifier Gain (if any) And the average value is Average = Peak Value + Duty Factor Note : If the measured frequencies are fall in the restricted frequency band, the limit employed must be quasi peak value when frequencies are below or equal to 1 GHz. And the measuring instrument is set to quasi peak detector function. 4.5 Activate Time This EUT is operated by manually, and Activate Time is less than 5 second after being released. 4.6 Calculation of Duty Factor The duty factor is calculated with following formula :
