2 Product overview RTX3741 is a USB type A dongle with slide switch that can establish a wireless connection with the RTX headsets from the RTX725x series and B169 DECT Speakerphone. The dongle supports dual mode, meaning that it can be used either as a Fixed part (FP), or Portable part (PP).
Damage Inspection The following is the recommended procedure for you to use for inspection: 1. Examine all relevant components for damage. 2. Make a “defective on arrival – DOA” report or RMA to the operator. Do not move the shipping carton until the operator has examined it. If possible, send pictures of the damage. The operator/regional representative will initiate the necessary procedure to process this RMA. They will guide the network administrator on how to return the damaged package if necessary. 3.

3.3 Soft Client Support Combined with one of our four RTX headsets, the DET dongle supports the audio and USB API for the Skype for Business (Lync) application. Moreover, other call clients can be supported, but they require either a PC tool to be running (see chapter 4 PC setup tool), or an RTX USB HID API to be supported by the client. All call related controls are managed via the headset controls and/or desk phone/PC. The call is initiated from the Soft Call Client running on the PC/laptop.
5 Use case scenarios The following chapter aims to give you an example of a certain system setup in order to show the connection and functionality of the device. 5.1 DECT USB dongle on PC The following use case presents a DECT dongle connected to a laptop that acts like a base with Call control (e.g. Skype for Business).
