For example, obstacles such as trees and metals will absorb wireless signals to some extent, so that the distance of data transmission is affected to some extent in practical applications. B.It is recommended that the metal enclosure be not installed in the metal enclosure as it is shielded from radio frequency signals. C.PCB board: as the metal will weaken the function of the antenna, when distributing the board to the module, it is strictly prohibited to lay the floor and wire under the module antenna. It is better if it can be hollowed out. 10.Recommended reflux temperature:
Key features of the profile:
-Initial Ramp=1-2.5/sec to 175 equilibrium
-Equilibrium time=60 to 80 seconds
-Ramp to Maximum temperature (250)=3/sec Max
-Time above liquidus temperature(217): 45 - 90 seconds
-Device absolute maximum reflow temperature: 250 11.Application schematic:
Lease refer to the application schematic diagram for reference only!
(OEM) Integrator has to assure compliance of the entire end-product incl. the integrated RF Module. For 15 B (15.107 and if applicable 15.107) compliance, the host manufacturer is required to show compliance with 15 while the module is installed and operating. Furthermore the module should be transmitting and the evaluation should confirm that the module's intentional emissions (15C) are compliant (fundamental / out-of-band). Finally the integrator has to apply the appropriate equipment authorization (e.g. Verification) for the new host device per definition in 15.101. Integrator is reminded to assure that these installation instructions will not be made available to the end user of the final host device. The final host device, into which this R-F Module isintegrated" hasto be labelled with an auxilliary lable stating the FCC ID of the RF Module, such as "Contains FCC ID: 2AR7VC-8082U"
"This device complies with part 15 of the FCC rules. Operation is subject to the following two conditions:
(1) this devicemay not cause harmful interference, and
(2) this devicemust accept any interference received, including interference thatmay cause undesired operation."
NOTE: This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to part 15 of the FCC Rules. 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. Changes or modifications to this unit not expressly approved by the party responsible for compliance could void the user's authority to operate the equipment. XIAMENSHIXINWEI C-CHIP TECHNOLOGY CO., LTD. TYJW-JHS V1.1 Module statement The single-modular transmitter is a self-contained, physically delineated, component for which compliance can be demonstrated independent of the host operating conditions, and which complies with all eight requirements of 15.212(a)(1) as summarized below. 1) The radio elements have the radio frequency circuitry shielded. 2) The module has buffered modulation/data inputs to ensure that the device will comply with Part 15 requirements with any type of input signal. 3) The module contains power supply regulation on the module. 4) The module contains a permanently attached antenna. 5) The module demonstrates compliance in a stand-alone configuration. 6) The module is labeled with its permanently affixed FCC ID label 7) The module complies with all specific rules applicable to the transmitter, including all the conditions provided in the integration instructions by the grantee. 8) The module complies with RF exposure requirements. This transmitter/module must not be collocated or operating in conjunction with any other antenna or transmitter.
