The calculated shelf life for the dry packed product shall be a 12 months from the bag seal date. Humidity indicator cards must be blue, <30%. 2.Products require baking before mounting if humidity indicator cards reads > 30% temp < 30, humidity < 70% RH, over 96 hours. Baking condition: 125, 12 hours. Baking times: 1 time. 7.3 Recommended Reflow Profile Reflow soldering shall be done according to the solder reflow profile,Typical Solder Reflow Profile is illustrated in Figures 8. The peak temperature is 245. Figure 8 Typical Solder Reflow Profile 11 FCC Statement This device complies with part 15 of the FCC rules. Operation is subject to the following two conditions: (1) this de vice may not cause harmful interference, and (2) this device must accept any interference received, including i nterference that may cause undesired operation. Changes or modifications not expressly approved by the party responsible for compliance could void the users au thority to operate the equipment. NOTE: This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant t o part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interferenc e in a residential installation. This equipment generates uses and can radiate radio frequency energy and, if not in stalled and used in accordance with the instructions, may cause harmful interference to radio communications. H owever, there is no guarantee that interference will not occur in a particular installation. If this equipment does ca use 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 important announcement Radiation Exposure Statement This equipment complies with FCC radiation exposure limits set forth for an uncontrolled environment. This equipment should be installed and operated with minimum distance 20cm between the radiator and your body. This transmitter must not be co-located or operating in conjunction with any other antenna or transmitter. Important Note:
In the event that these conditions cannot be met (for example certain laptop configurations or co-location with another transmitter), then the FCC authorization is no longer considered valid and the FCC ID cannot be used on the final product. In these circumstances, the OEM integrator will be responsible for re-evaluating the end product (including the transmitter) and obtaining a separate FCC authorization. End Product Labeling The final end product must be labeled in a visible area with the following" Contains FCC ID:
2ASJA-B8821CU1
". Manual Information to the End User The OEM integrator has to be aware not to provide information to the end user regarding how to install or remove this RF module in the users manual of the end product which integrates this module. The end user manual shall include all required regulatory information/warning as show in this manual. 10 / 10
