Sennheiser OfficeRunner/DW Pro Resets

Standard Reset (DCA Reset)

For you have no lights on the headset/base whatsoever. This is also a good general first step for most issues.

1. Remove the AC/DC power cord from the back of the base (under the yellow sticker) Note: if the USB cord is being used, unplug that as well.
2. Wait about 20 seconds and plug the cord(s) back in.

Dipswitch Reset

Good for red diamond in the middle of the base, audio issues, and general connectivity issues.

1. Place the headset in the charging base
2. Remove the DCA power cord from the back of the base (under the yellow sticker). Unplug the USB cord (under the orange sticker) if it is being used
3. Note which positions the 6 white dip switches are in (so you can move them back to their original positions later in step 5), then move all 6 switches down
4. Plug the DCA power cord (and USB if in use) back into the base and wait for 20 seconds.
5. Move all 6 switches back UP and move any switches back down if needed (referring to step 3)
6. Test out your headset!

New Mic Sync/Manual Pairing

Do this when your headset isn't automatically pairing to the base.

1. Remove the headset from the charging base
2. Press and hold the mute and on/off buttons until the headset flashes red and blue
3. Put the headset back into the base. The light on the headset will turn blue when the pairing is complete

Manual Disconnect/Reconnect - Try this for any type of pairing or connectivity issues

If you've already tried the dipswitch reset and you're still having issues, try this.

1. Take the headset off of the base and ensure the headset is turned off
2. Press and hold the ON/OFF button on the headset until the battery lights disappear (the headset may flash red while you're holding the ON/OFF button). Continue to hold down until we see a red diamond and no battery lights on the cube
3. Place the headset back on the base. The headset will flash red/blue to indicate that it's pairing. Remove the headset from the base once we see a solid blue light on it. This lets us know the headset has successfully paired to the cube
