During the pairing process, both a new channel number and a new address are selected by this Module and get communicated to the external receiver. Each time it is paired with a receiver, the Module increases the frequency by 2 channels, meaning 10MHZ increments. The change is always in the ascending order and wraps around once the maximum normal operating channel number (channel 15) has been exceeded. For example, if starting at channel 1, then the following are the order of channel numbers every time pairing is performed: 1, 3, 5, 7, 9, 11, 13, 15, 2, 4, 6, 8, 10, 12, 14, 1, 3, ......

Indicators: There are 2 LED indicators on the top side of the Module. The left one, D13, indicates RF transmission and pairing status while the right one, D15, indicates the power supply/battery level status. Here are the indication types and what they mean: LEFT SIDE LED (D13) SYMBOL COLOR SOLID/FLASHINGSTATE NONE SOLID OFF EITHER OF THE FOLLOWING :  IN SLEEP MODE  IN AWAKE MODE BUT WITH NO RF TRANSMISSIONS BLUE FAST FLASHING NORAML RF TRANSMISSIONS IN PROGRESS BLUE SLOW FLASHING PAIRING RF TRASMISSIONS IN PROGRESS RIGHT SIDE LED (D15) SYMBOL COLOR SOLID/FLASHINGSTATE NONE SOLID OFF IN SLEEP MODE AND BATTERY LEVEL IS NOT LOW GREEN SOLID ON IN AWAKE MODE AND BATTERY LEVEL IS HIGH YELLOWSOLID ON IN AWAKE MODE AND BATTERY LEVEL IS MEDIUM RED FAST FLASHING IN AWAKE MODE AND BATTERY LEVEL IS LOW RED SLOW FLASHING IN SLEEP MODE AND BATTERY LEVEL IS LOW Confidential and Proprietary Information ● DenMat Holdings, LLC ●1017 W. Central Ave., Lompoc, CA 93436‐2701 ●1‐800‐433‐6628 ●Page 8 b. Pairing With a Receiver: i. The receiver (a separate unit not supplied with this module) must be put into Pairing mode in order to start the pairing process. This means that it must be on the particular pairing frequency and pairing address as specified by this Module. ii. Then, the pairing button on this Module must be pressed continuously until the left side indicator starts flashing in blue color in slow speed. This usually takes about 1 second or longer. iii. Once the indicator has started flashing in blue, release the button and the Module will continually transmit Pairing packets for about 5 seconds. The pairing mode packets contain the new wireless address and new channel for the receiver to learn. At the end of the pairing mode, the Module will save the newly assigned channel and address in its non-volatile memory and then automatically goes to sleep mode. c. Sleep and Wakeups: The Module enters a low power sleep mode as soon as power is applied to it. In th…

SAR Exclusion Justification Test exclusion thresholds for 100 MHz to 6 GHz at test separation distances ≤ 50 mm Guidance document reference: 447498 D01 General RF Exposure Guidance v05r01, page 11, paragraph 4.3.1(1). The 1-g and 10-g SAR test exclusion thresholds for 100 MHz to 6 GHz at test separation distances ≤ 50 mm are determined by: [(max. power of channel, including tune-up tolerance, mW)/(min. test separation distance, mm)] * [√f(GHz)] ≤ 3.0 for 1-g SAR and ≤ 7.5 for 10-g extremity SAR, where • f(GHz) is the RF channel transmit frequency in GHz • Power and distance are rounded to the nearest mW and mm before calculation • The result is rounded to one decimal place for comparison • 3.0 and 7.5 are referred to as the numeric thresholds in the step 2 below The test exclusions are applicable only when the minimum test separation distance is ≤ 50 mm and for transmission frequencies between 100 MHz and 6 GHz. When the minimum test separation distance is < 5 mm, a distance of 5 mm according to 5) in section 4.1 is applied to determine SAR test exclusion. SAR test exclusion analysis: Assumptions: Since the exact separation distance may vary from sensor to sensor, the minimum separation distance of 5 mm is assumed per the guidance document. Max. power of channel:0.4mW Min. separation distance:5mm Max. frequency:2.48GHz [(Pwr/Dist)*√Freq.] =0.1 The result of the above SAR threshold calculation demonstrates that the result is less than the 1-g numeric threshold of 3 and the 10-g numeric threshold of 7.5. Conclusion: The above analysis shows that the evaluated device qualifies for exemption from SAR testing. Signed: David Light,Sr. Wireless Test Engineer 4/22/2014 Nemko USA, Inc.
