Hardware & Software installation

Hardware Installation

The module is a build in module. It will be used in-house production as an embedded device over USB 2.0 interface and there is no need any interaction with end-user. Positioning of the module is defined by assembly operator instructions for each product by Vestel. The WI-FI + BT combo module should be mounted by considering operating temperature. The temperature of the installation location should be between 0°C and 65 °C. The module can be installed in mobile or fixed hosts and must meet the RF exposure compliance separation distance of “20cm” between the user / bystander and the antenna. The implementation of the module in a specific end-product should also be reviewed to ensure compliance with the FCC and IC requirements for SAR and MPE. 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.
