3About the device
The RTX745x device is an EHS/USB wireless base station which provides USB connectivity to PC/laptop/desktop phone
and DECT connectivity to RTX725x headsets/DECT speakerphone. It is designed as a Plug & Play solution, meaning that
no additional driver installations are needed.
The figure below (Fig.1) illustrates the high-level description of the communication possibilities of the device. The
RTX745x base is connected to a host (PC or desktop phone) with USB interface. It acts as a DECT base station for
RTX725x headset and DECT speakerphone.
Fig.1 Device connections
The RTX745x serves as a base and charger for the RTX725x series headsets. The primary application is within call
centers and office environments allowing the user access to internet/VoIP calls, music playback via the PC/mobile
phone, and desk phone connectivity.
3.1 Device overview
The drawings below illustrate the dimensions of the device (Fig. 2).

5Call activity on base
To have call activity on the base, a master headset must be registered and locked to the base. If the master headset
loses connection during call activity, all the calls will be terminated.
5.1 Incoming call
The base will notify the user with visible and audible indication whether an incoming call is from EHS or USB line. If
both lines are in idle state and an incoming call is received to one of the lines, the base rings and displays the call
(Fig.11). However, if there are two simultaneous incoming calls from two different lines, the active control is made by
the first incoming call (the first that came is served first). The second incoming call cannot be accepted by the
base until the first incoming call has been answered or ended, or the line is swapped manually by the user (Fig. 12). In
case of having one of the lines occupied (in active call), the new incoming call will be displayed as waiting in a queue
(Fig.13).

5.2 Active call
When a call is active, the base displays the active call and the audio path is connected between the far-end party and
RTX725x headset. It is not possible to have more than one active call on a single line at the same time.
Fig.14 Active call
5.3 On-hold call
When a call is put on-hold, the base displays a hold call status and the audio path is disconnected between the far-end
party and the RTX725x headset (Fig.15 Two calls, one on hold). It is not possible to set EHS active call on-hold by the
base.
Fig.15 Two calls, one on hold

RTX745x GUIDE 1.0 14 |P a g e
Proprietary and Confidential
5.4 Multiple calls
There is more than one call existing in a single line. EHS line does not support multiple call.
Fig.16 Multi call
5.5 Multiple line
There is more than one call existing in different lines.
5.6 Active & Inactive line
When a line is active, the base displays active line and the audio path is connected via the line. It is not possible to
have more than one active line at the same time.
When a line is inactive, the base displays inactive line and the audio path is disconnected via the line. It is not possible
to have manual call control of the base when the line is inactive.
5.7 Call termination
All calls will be terminated when the master headset loses link or is placed on the cradle.
5.8 Line swapping
In the case two calls are established in two different lines, one of them is being the active call in the active line. To
make the line swapping simpler, active line is swapped automatically depending on call activities change. It can be one
of the following scenarios:
User makes an outgoing call by softphone or desktop phone.
User retrieves USB held call by softphone.
User swaps USB call by softphone.
User accepts an incoming call.
Call from first active line is ended and other call is existed in second inactive line.
The user can also swap the line from the base manually. When a line is swapped successfully, between two different
lines, a visible indication is shown on base.

5.9 Microphone muting
Microphone muting control is separated into two muting statuses. Each line has its own microphone muting control.
When the line is switched, the related microphone muting control will also be switched.
5.10 Volume control
Similar to the microphone, the volume control is also divided into two sets of volume. This means that, each line has
its own volume control. When the line is switched, the related volume control will be also switched.

6Features overview
This section aims to introduce you to the available features on the RTX745x base. Some of the features will be briefly
described through the sections below, whereas the main highlights will be presented via a table with function
descriptions.
6.1 Soft client support
The base, combined with one of the RTX725x headsets, supports the audio and USB API of the following applications:
Skype for Business
Microsoft Teams
Customer client support implemented in PC tool
The RTX745x base can be used with both PC Windows and MacOS.
6.2 EHS interface
The RTX7451 supports EHS phones. The base is prepared to be compatible with various EHS standards. This is done by
having a slider switch that enables 6 separate HW configurations for the audio routing. The PC Setup tool is used to
configure the optimal settings for the SW configuration.
The RTX725x supports 2 active calls, meaning that the 3rd incoming call will be rejected or ignored. If during a call the
user receives an incoming call, the call can be rejected by double pressing the Multi-Function key or accepted by long
pressing the same key. The long press will answer the incoming call and put on hold the current one.
