When a Poly or Plantronics wireless headset starts misbehaving — dropping the connection, ignoring the base, refusing to pair — a reset fixes it more often than anything else. The procedure differs by family, so find yours below.
Key takeaways
- Three different procedures: CS-series DECT, Savi/Voyager Office multi-device, and Voyager UC Bluetooth.
- The waiting period matters — give it around 30 seconds, not the commonly quoted 10.
- Each reset ends with a specific LED or voice confirmation. If you don't get it, the reset didn't complete.
- On Savi headsets, if a base reset doesn't work, removing the headset battery as well is the deeper step.
- Bluetooth Voyager resets involve the phone too — unpairing and restarting it is part of the procedure.
CS500 series (CS510, CS520, CS540)
The CS family connects to a desk phone over DECT, so the reset is entirely about the base and headset. This applies to the Poly CS540 and its siblings.
- Unplug the base from its AC/DC power adapter.
- Take the headset out of the base.
- Remove the battery from the headset. On most models this means opening the battery gate first; some models have sealed batteries, covered in the note below.
- Wait about 30 seconds. Ten is commonly quoted, but longer gives the sensors time to fully clear.
- Reverse the steps: reconnect the battery, close the battery gate, then plug the base back into power.
- Wait for the base lights to come up and the Power LED to stay solid. Place the headset on the base and leave it for 10 seconds — the white LED on the headset starts blinking. About 10 seconds after that, the charging LED on the right side begins blinking green.
That green charging LED is your confirmation the reset completed.
Myth
Ten seconds is long enough to wait during a headset reset.Reality
Ten seconds is the figure most people quote, and it often works — but not always. The wait exists so the base and headset fully discharge and clear their state, and the sensors need a moment beyond the power draining. Around 30 seconds is more reliable. If a reset doesn't take, an impatient wait is one of the most common reasons.Savi and Voyager Office families
These headsets connect to a desk phone, computer, and often a mobile device at once, so there are more connections to clear. This applies to the current Savi 8400 series (8410, 8420, 8445) and Voyager Office models.
- Unplug the base from its AC/DC power adapter.
- Unplug the base from the computer (the USB cable).
- Take the headset out of the cradle.
- Wait about 30 seconds.
- Reverse the steps: connect the AC/DC adapter first, then the USB cable. The base lights come up showing power and connection status — green, white, or blue depending on model.
- Once the Power LED turns green, place the headset back in the cradle. The LED on the headset blinks, confirming the reset.
If that doesn't resolve it
Repeat steps 1 through 3, then also remove the headset's battery. Depending on the model this may require a battery removal tool, and some unlimited-talk-time models use sealed batteries. Reinsert the battery and continue from step 4.
Voyager UC Bluetooth family
Bluetooth Voyager headsets — including the Voyager Focus 2 — connect to a computer through the BT700 dongle and often to a phone as well, so the reset involves both.
- Unplug the BT700 USB dongle from the computer.
- Turn off the headset.
- If the headset is paired to a phone or tablet, unpair it there: Settings → Bluetooth → find the Poly device → Forget.
- Restart the phone or tablet. Allow around two minutes.
- Turn the headset back on. You'll hear "Power on, battery high."
- Plug the BT700 dongle back into the computer. It blinks while connecting, and the computer registers it as a new device. With the headset nearby, the blinking becomes solid blue and you'll hear "PC connected."
- Re-pair the headset to your phone or tablet, putting the headset into pairing mode so the device can find it. You'll hear "Phone 1 connected."
Once done, check firmware on both the headset and the dongle through the HP Poly Studio App — the current name for the software formerly called Poly Lens, and before that Plantronics Hub.
Re-pairing a Voyager headset to an Office Base
If the problem is between a Voyager 4300/4200-series or Focus 2 headset and its Office Base, re-pair the two directly:
- Turn off the headset.
- Press the pairing button on the back of the Office Base for 2 seconds. The Bluetooth logo flashes red and blue, indicating pairing mode.
- Turn the headset on.
- Put the headset into pairing mode and let the two find each other.
- You'll hear "Base connected" in the headset. The connection is re-established.
If a reset doesn't fix it
A reset clears state — it doesn't repair hardware or replace a worn battery. If a headset resets successfully but still loses connection, cuts out, or won't hold a charge, the battery is a more likely cause on any headset more than two or three years old. Our wireless headset battery and charging guide covers when a battery is the real problem.
How do I reset a Plantronics CS540?
Unplug the base from power, remove the headset from the base, take out the headset battery, and wait about 30 seconds. Reconnect the battery and the base power, wait for the Power LED to stay solid, then dock the headset. The white LED blinks after 10 seconds, then the charging LED blinks green — that confirms the reset.
How do I reset a Poly Savi wireless headset?
Unplug the base from both the AC/DC adapter and the computer's USB cable, remove the headset from the cradle, and wait about 30 seconds. Reconnect power first, then USB. When the Power LED turns green, dock the headset — its LED will blink to confirm. If that doesn't work, repeat while also removing the headset battery.
How do I reset a Poly Voyager Focus 2?
Unplug the BT700 dongle, power off the headset, and unpair it from your phone under Bluetooth settings. Restart the phone, turn the headset back on, reconnect the dongle (wait for solid blue and "PC connected"), then re-pair to your phone until you hear "Phone 1 connected."
How long should I wait during a headset reset?
Around 30 seconds. Ten seconds is commonly quoted and often works, but the longer wait lets the base and headset fully clear their state, and impatience is a common reason a reset doesn't take.
My headset still isn't working after a reset. What now?
A reset clears state but can't fix hardware or a worn battery. If the headset resets successfully yet still drops calls or won't hold charge, the battery is the likely cause on anything more than two or three years old.
Most wireless headset problems clear with the right reset for your family. Work through the steps for yours, watch for the LED confirmation at the end, and if the symptoms return, the battery is the next thing to check. Call our team at 877-999-3838 if a reset doesn't hold.
