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).

Enables DECT access for a USB desktop phone on the RTX VoIP system 

 
Since the DECT dongle can run one mode at a time, you can switch between the two functionalities by using the slider 
switch. 
 
The device is designed to be easy to use with a desk phone/PC/laptop with a very good sound quality. The chosen 
microphone is balanced together with the headset filters to reduce the background noise, in order to provide an 
ultimate speech intelligibility. The receivers are balanced to the receiver housing and cushion, allowing the headset to 
provide the user extreme stereo experience. Since the device is using the DECT technology, it can remember 4 
registrations 

 one primary and three secondary. However, only one single registration can be a DECT speakerphone. 

The audio can be directed to the headset or speakerphon

e, depending on the user’s choice.

 When the headset is 

connected via the RTX3741 DECT Dongle to a PC, the user may access calls from Soft Call Clients, such as Skype for 
Business (see 

3.2 Soft Client support

 for more details).
