This section provides general information about inspecting, connecting, and installing DynaFlex II Go products. ## About Inspection Before unpacking the device, it is important to inspect its secure packaging to make sure it has not been tampered with in storage or in transit. MagTek provides details for inspecting the integrity of the device’s secure packaging in *D998200594 DynaFlex II Go Package Inspection Document*. It is important to thoroughly inspect a new device before deployment, and regularly inspect devices in live usage (including its immediate surroundings) to make sure malicious individuals have not tampered with it. MagTek recommends conducting inspection training for all device operators, and an inspection schedule with checkpoints in place to make sure operators are performing inspections as specified and as scheduled. MagTek provides an easy-to-follow device inspection reference *D998200593 DynaFlex II Go Device Inspection Document*. ## About Host Software DynaFlex II Go products do not have a display. In any solution, DynaFlex II Go must be connected to a host, which must have software installed that can communicate with the device and is capable of processing transactions. To set up the host to work with DynaFlex II Go, follow the installation and configuration instructions provided by the vendor of the host or the host software. For information about developing custom host software, see section 9 Developing Custom Software. ## Connecting DynaFlex II Go to a Host The following sections describe how to connect DynaFlex II Go to a host using the available USB-C receptacle or Bluetooth® Low Energy (LE) connections. #### **How to Connect DynaFlex II Go to a Host Computer via USB-C**
