Hunter Fan & Light Remote Control Transmitter Operational Description Description: The top box of the diagram below represents all of the potential keys that may be pressed for the Hunter transmitter. Pressing any key generates an encoded PCM code word which will modulate on a 350 MHz RF carrier for transmission. The encoded PCM code word is obtained from encoder U1 and is ASK modulated by the RF oscillator formed by transistor Q2. Encoder U1 also provides four selectable security bits which can be set by the user.

All data was recorded on Industry Canada Registered Site IC-2953. Canadian Emissions designator L1D365K. 2) Device is exempt from routine RF exposure testing per FCC Part 2.1091. 3) Device contains an integrated antenna. It is not detachable or replaceable by the user. 4) All buttons cease transmission immediately upon release of button (i.e. less than 100 ms). This satisfies the 5 second maximum duration requirements of Part 15.231(a)(1). 5) The manufacturer made the following modification to comply: a. Capacitor C12 changed from 33pf to 22pf b. Resistor R3 changed from 75kΩ to 215 kΩ Conclusion: The tests listed in the Summary of Testing section of this report have been performed and the results recorded by Underwriters Laboratories Inc. in accordance with the procedures stated in each test requirement and specification. The test list was determined by the Applicant as being applicable to the Equipment Under Test. As a result, the subject product has been verified to comply or not comply as noted in the Summary of Testing with each test specification. The test results relate only to the items tested.
