NEUTRON EMC LAB. Report No.NEI-FCC-P-03028 5/34 1. General Information 1.1 Applicant Name Chicony Electronics Co., Ltd. Address No. 25 Wu-Gong 6 Th Rd., Wu-Ku Industrial Park, Taipei Hsien, Taiwan, R.O.C. 1.2 Manufacturer Name N/A Address N/A 1.3 Equipment Under Tested Name: Wireless Keyboard Trade Name: Chicony Model No.: KR-0350 1.4 OEM Brand/Model (if applicable) OEM Brand(s)/Model(s) except the basic model in sub-clause 1.3 is(are) the follows: OEM Brand: N/A Model No.: N/A 1.5 Product Descriptions(Application/Features/Specification) The EUT is a Wireless Keyboard. A major technical descriptions of EUT is described as following: A. Operation Frequency CH1: 27.145 MHz and CH2: 27.195 MHz B. Modulation Type FSK C. Antenna Designation Integral D. Number Of Channel 2 E. Channel Spacing N/A F. Operation Methodology The EUT encoder generates a pulse code serially transmit (typical designation) into the modulator(or called as mixer) stage in circuit. This pulse signal mixed with the carrier at modulator(mixer) stage by way of FSK mode frequency modulation. The modulation depth is designed such as ± 5KHz in this application, that means the pulse(may be at high level state or low level state) will trigger the oscillator to generate a frequency at a specified fundamental frequency +5KHz or −5KHz, depended on the designation. For example, if the carrier frequency defined as fundamental frequency +5KHz at high level state, then the alternative carrier frequency will be fundamental frequency −5KHz at low level state. Based on the application, features, or specification exhibited in User's Manual, the EUT is considered as an ITE/Computing Device. More details of EUT technical specification, please refer to the User's Manual (Attachment - E.)
