factory resets

To update the firmare on your EPOS|Sennheiser device, first download the EPOS Connect App to

your computer. CLICK HERE.

Then connect your headset.

Corded USB headsets

Easy peasy, just make sure it’s plugged in!

Bluetooth Headsets

Adapt 200 and above models;

Ensure the dongle AND the headset are connected. You’ll need to connect the headset by a USB

cable.

MB Pro models

Insert your thumbnail between the headset and the leatherette earpad (on the same side of the

headset as the microphone boom arm) and remove, with the plastic ring to reveal the micro-USB

port located underneath and then use a micro-USB to USB cable to connect it with your PC. If you

have a USB dongle you should also plug this in.

DECT Wireless Headsets (SDW models, D10PH, D30PH, DW models)

Connect the base unit to a PC. If your headset isn’t designed to work with a computer (ie is

deskphone only) you’ll still have a micro usb port on the back and can connect to a PC via a micro-

usb to USB cable.

The EPOS Connect app will recognise your headset or dongle and list it. Check the updates page and

update the firmware accordingly.

Factory Reset for DECT Headsets only

First ensure that all power sources have been disconnected (both via USB and mains supply).

Wait a moment to ensure there is no residual charge left in the base station.

On the back of the base, press and hold the reset button (the small black button located near the

tiny white DIP switches). NB on the SDW series headsets there are 2 buttons; S1 and S2. You’ll

need to use S1.

Whilst continuing to press the reset button, reconnect power to the base. Once power has been

reconnected, you may release the reset button.

The base station should now carry out a reset
