These limits are designed to provide reasonable protection against harmful interference in a residential installation. This equipment generates, uses and can radiate radio frequency energy and, if not installed and used in accordance with the instructions, may cause harmful interference to radio communications. However, there is no guarantee that interference will not occur in a particular installation. If this equipment does cause harmful interference to radio or television reception, which can be determined by turning the equipment off and on, the user is encouraged to try to correct the interference by one or more of the following measures: —Reorient or relocate the receiving antenna. —Increase the separation between the equipment and receiver. —Connect the equipment into an outlet on a circuit different from that to which the receiver is connected. —Consult the dealer or an experienced radio/TV technician for help. 15.19 (labeling not on EUT due to size must be in manual: This device complies with part 15 of the FCC Rules. 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. 1. Definition list Sender: A wireless sending module. Receiver : A wireless receiving module which displays temperature. BFunctional Specification 1. Features: a. Temperature Range: 80`F-120`F b. The system included a receiver and a sender. H i x s o n Te m p Ta g (V5.00)- m m a a n n u u a a l l Copyright@2005 Chaney Instrument Co Inc. –All rights reserved 2 c. The system will transmit the temperature 4 times per hour. ( d. Temperature alarm function: A red LED and LCD will flash in the receiver when temperature range over 104`F and it will display “- - - “when the temperature range is outside 80- 120`F. 2. LCD display 1) The Sender without LCD. 2) The receiver with following LCD: 3. Operation a. When power on the receiver, its LCD will fully display as the below figure, then the LCD will display as next figure. b. The time code will be preset in the factory and exit factory by pair which is matched the time code. c. Customer can register the new time code by pressing the rest key on the back side of the receiver .(need to screw out the screw to access the reset key) The receiver will clear the old time code and keep it in learning mode to learn the new time code from a transmitter once the reset key is pressed. The learning process should be by placing a pair in a shielded box or by keeping the pair far away from any other sets in order to avoid any interference from any other pairs of receivers and transmitters. d. The learning process takes 15 minutes to learn the time code for the handshake. e. Transmitter sends the data every 15 minutes. f. The LCD of the receiver will display “-E-“ when the receiver cannot receive any signal for more than 8 consecutive times.

ADT (Shanghai) Corporation 2F, Building C, No.1618, Yishan Rd., 201103, Shanghai, China Dec. 16, 2005 FCC ID: RNE00991 The following lists are the answers for the comments on Dec, 15, 2005, please kindly have a review on it: 1) Please adjust the following exhibits to only show the device covered by this application (remove information regarding the RX) :a) Block Diagram; b) Labeling Exhibit; c) Schematics Re: See the attachment (RNE00991)BlkDia_1216; (RNE00991)Label_1216; (RNE00991)Schem_1216. 2) Layout (first page of schematics) shows a 433.92 MHz resonator, while this application appears to be for 315 MHz. Please adjust/correct the application as necessary. Re: See the attachment (RNE00991)Schem_1216. 3) The users manual does not contain proper FCC statements such as the following that are typically required: Re: See the attachment (RNE00991)UserMan_1216. 4) The correction factor applied for average measurements is based upon 300 msec. This is not allowed as the FCC rules cite a maximum worse case of 100 msec. This makes an almost 9.5 dB difference in the allowed duty cycle correction. (20 log 0.64 = 3.9). This will cause reading at the 2nd, 3rd, and also possibly the 5th harmonic to exceed the limit. Re: See the attachment (RNE00991)TestRpt _1216. 5) There are a PK few readings above 1 GHz which exceed 54 dBuV/m, but average results were not shown. Where peak emissions exceed average limits, average results must be provided as well. Please correct. Re: See the attachment (RNE00991)TestRpt _1216. 6) FYI....The RX appears to be a super-regenerative device and must be approved either by a separate Certification application, or a DoC application. Please note that to qualify to perform DoC applications, the test lab must be accredited by an acceptable agency and meet the requirement of 2.948(e) to perform testing under the DoC procedure and the device has additional labeling and manual requirements for the DoC. Currently labs from China do not appear as an accredited test lab on the FCC site under 2.948(e). Re: The FCC DOC report is issued by our head office in Taiwan. See the attachment (RNE00991)TestRpt.Doc _1216. Thank you very much.
