OR Red Diamond with Battery vs Red Diamond without Battery Lights Troubleshooting

Updated by Kamika Royal on Sep 13, 2024

There are a lot of lights on the Sennheiser OfficeRunner, but the one we don't want to see is a red light on your charging base. If you see a red diamond in the middle of the cube, it means the headset and base are not synced properly OR you've got a dead battery. Here's how to fix it!

Steps for Red Diamond, NO Battery Lights:


Steps for Red Diamond, WITH Battery Lights:
  1. First try a Dipswitch Reset. That fixes all sorts of things!
  2. If this doesn't work try: Pairing a new microphone: Grab another Sennheiser headset and place it on the base and let it pair. Once paired, check to see if there is still a red diamond. If there is not pair your original headset back to the base to see if the red light clears.
  3. If there is still a red diamond, try moving the power cord into a different outlet
  4. If that doesn't work, try a manual disconnect (hold down the on/off button on the headset until the headset's light flashes red and the battery lights go away, then put headset back on the base to pair it again)
  5. If there is a still a red diamond, try a manual pairing (steps below)
    1. Disconnect the power cord from the base.
    2. Remove headset from base.
    3. Press and hold both the power and mute button on the headset until the headset light flashes red/blue to place it into pairing mode . (Do this while the power cord is still out!)
    4. Release buttons and place the headset back on the base.
    5. Once back on the base, immediately reconnect power cord.
    6. Once the power cord is reconnected, the manual pairing should be complete
