C3KKB10Wireless Keyboard

American Telecommunications Certification Body Inc. 6731 Whittier Ave, McLean, VA 22101 July 5, 2002 RE: Microsoft Corporation FCC ID: C3KKB10 After a review of the submitted information, I have a few comments on the above referenced Application. 1) The Users Manual Contains the following information: Regulatory Information This device complies with part 15 of the FCC Rules and Industry Canada RSS-210. Operation is subject to the following two conditions: (1) This device may not cause harmful interference, and (2) this device must accept any interference received, including interference that may cause undesired operation. a) Tested to comply with FCC standards. For home and office use. Model number: Wireless Optical Desktop receiver (all models), FCC IDs C3KKB9 and C3KMS9; Wireless Optical Desktop Pro receiver (all models), FCC IDs C3KKB10 and C3KMS9. This paragraph sounds like the FCC ID's are also being applied to the receiver portion of the device. Are the receivers labeled with the FCC ID Number? The receivers should be labeled only with the proper FCC DoC Labeling (Logo, etc.) and NOT with the FCC ID number. The FCC ID number is applicable only to the keyboard portion. Please adjust the information above so that it is not misleading. 2) The test reports states that 3 samples were provided. It is not clear why 3 samples were tested. Please explain. Timothy R. Johnson Examining Engineer mailto: [email protected] The items indicated above must be submitted before processing can continue on the above referenced application. Failure to provide the requested information may result in application termination. Correspondence should be considered part of the permanent submission and may be viewed from the Internet after a Grant of Equipment Authorization is issued. Please do not respond to this correspondence using the email reply button. In order for your response to be processed expeditiously, you must submit your documents through the AmericanTCB.com website.

FCC ID: C3KKB10 ADT No.910612R04 Operational Description The transmitter of the EUT (Wireless Keyboard) is powered by 3V Battery. The transmitter use Wire Antenna. The output power of this device is very low. Under normal use condition, the transmitter and the receiver are quite close, so high EIRP power is neither necessary nor allowed because of interference.
