The following description of the Wall Mount Programmable Thermostat was supplied by Acumen, Inc.: Overview of the EUT Applicant Acumen, Inc. 101A Executive Drive, Suite 200 Sterling, VA 20166 Trade Name & Model No. Wall Mount Programmable Thermostat / WMT FCC Identifier EPKWMT05TX Use of product Programmable Thermostat Transmitter activation [ x] Manual and automatically deactivate within 5 seconds of being released [ ] Periodic transmissions Frequency Range (MHz) 350.1 Antenna Requirement The EUT uses a permanently connected antenna. Manufacturer name & address Acumen, Inc. 101A Executive Drive, Suite 200 Sterling, VA 20166 EUT type Production EUT received date: March 27, 2003 Operating condition: Good 2.2 Related Submittal(s) Grants This report is for use with an application for certification of a low power transmitter. One transmitter is included in the application. 2.3 Test Methodology Both AC mains line-conducted and radiated emissions measurements were performed according to the procedures in ANSI C63.4 (1992). Radiated tests were performed at an antenna to EUT distance of 3 meters, unless stated otherwise in the "Data Sheet" of this Application. All other measurements were made in accordance with the procedures in part 2 of CFR 47. Intertek EMC Report for Acumen, Inc. on the WMT FCC Part 15.231 File: 3038984-37-1-1 Page 5 of 18 2.4 Test Facility The Duluth 10-meter chamber site is located at 1950 Evergreen Blvd., Suite 100, Duluth, Georgia. The test site is a 10-meter semi-anechoic chamber. The site meets the characteristics of CISPR 16-1: 1993 and ANSI C63.4: 1992. For measurements, a remotely controlled flush-mount metal-top turntable is used to rotate the EUT a full 360 degrees. A remote controlled non-conductive antenna mast is used to scan the antenna height from one to four meters. The A2LA accreditation code for this site is 121624 under certificate number 1455.01. The Industry Canada file number for this site is IC 2077.
