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).

• Base / FP mode:
  Acts as a DECT base for the RTX725x headsets
  Acts as a DECT base for the B169 DECT speakerphone

• Headset / PP part:
  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 speakerphone, 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).

Package – Contents/Damage inspection

Before Package Is Opened
Please, examine the shipping package for evidence of physical damage or mishandling prior to opening. If there is a proof of mishandling prior to opening, you must report it to the relevant support center of the regional representative or operator.

Contents of Package
Please, make sure all relevant components are available in the package before proceeding to the next step.  Every shipped unit package/box contains a DECT dongle and a safety sheet.

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. If no damage is found, then unwrap all the components and dispose of empty package/carton(s) in accordance with country specific environmental regulations.

RTX DECT Dongle Mechanics
With such small dimensions as 35mm (length) and 19mm (width), the device can be easily carried and plugged into any computer, supporting a USB. For more details, please see the drawing below.

LED Indicators
The dongle has 3 LED indicators that signal different functional states of the device. The indicators are off when the unit is not powered on. To give you a better understanding of the LED color and states, we have numbered them as LED 1, LED 2 and LED 3.

Depending on the LEDs color, they will indicate call and registration status to the user. Each LED has its own color identification, which is presented in the table below.

LED Patterns
The LED supports different kinds of patterns, such as fast/normal/slow blink and breathing. Technical details are explained in the table below.

LED Indications
The table summarizes the various LED states. It shows the LED indication for different statuses of the DECT dongle.

FUNCTION                STATUS                 LED PATTERN

DECT CONNECTION

| Registration, In progress| Blue| Blink alternately
Registration, Success| Blue and Green| Blink 3 times
Registration, Failed| Blue and Red| Blink 3 times
Master headset registered| Blue| ON
Master headset lost link| Red| ON

CALL

| Ringing| Green| Blink
Talk or Hold| Green| ON
Conference or intrusion call| Green| Breathing

Button features
The DECT dongle has one key which serves for starting the DECT registration and for resetting the device. Therefore, all setup is done by using the PC Setup tool.

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. It cannot be initiated from the speakerphone. It is outside the scope of the RTX3741 product.

4 PC setup tool

An external PC configuration tool is available for the DECT headset/dongle/base. It allows you to configure these devices by changing their parameters, upgrading their firmware and do upgrades of the PC tool itself. It is compatible  with corded and wireless headsets – RTX7xxx series. The PC Tool is available in a Windows version and a MacOS version. An example of the GUI interface is shown in the screenshots below. For a more detailed guide of the PC setup tool, please refer to the PC tool manual.

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.
