WHAT IS BLUETOOTH?
Bluetooth wireless technology provides a way for devices to communicate with each other using short-range radio frequency instead of wires. Any two Bluetooth devices can communicate as long as they both have Bluetooth turned on, they are within range, and they have been paired – a quick "handshake" that connects the two devices.
Bluetooth range is up to 33 feet (10 meters). Obstructions, such as walls or other electronic devices, can cause interference or shorten the effective range. For optimal performance, place your headset and phone on the same side of your body.

Pairing is the process of introducing your headset to your phone. Before using your headset for the first time, you must pair it with your Bluetooth phone. Normally you need to pair your headset with your phone only once. To see a demo of the pairing process, visit www.plantronics.com/easytopair.
QUICKPAIR™ TECHNOLOGY
Your new headset includes Plantronics QuickPair technology to simplify the Bluetooth setup process. The first time you turn your headset on, your headset automatically enters pairing mode for 10 minutes. Once paired successfully, your headset stays on for instant use.
If not successfully paired after 10 minutes, your headset automatically powers off. When you turn the headset on again, it automatically goes into pairing mode until successfully paired with a Bluetooth phone.
To pair your headset for the first time:
- Turn ON the Bluetooth feature on your phone.


TIP: For most phones, select Settings/Tools > Connections > Bluetooth > On. See your phone's user guide for more information.
- Press and hold the call control button to turn on your headset. (The indicator flashes red/blue to show that the headset is on and in pairing mode.)
TIP: If you don't see the red/blue flash, press and hold the call control button to turn your headset off, and then press and hold the call control button again until you see the red/blue flash.
- Use the commands on your phone to locate your headset.
TIP: For most phones, select Settings/Tools > Connections > Bluetooth > Search > 8XXPlantronics. See your phone's user guide for more information.
- When prompted for the passkey, enter 0000.
When pairing is successful, the red/blue indicator on your headset turns off. Your headset is now connected and ready to use.
SUBSEQUENT PAIRING
If you've already paired your headset with another device, follow these steps:
- Turn ON the Bluetooth feature on your phone.
TIP: For most phones, select Settings/Tools > Connections > Bluetooth > On. See your phone's user guide for more information.
- Turn the headset off by pressing and holding the call control button until the indicator turns red and then turns off.
- Turn the headset back on by pressing and holding the call control button until the indicator flashes red/blue. The headset remains in pairing mode for 3 minutes.
- Use the commands on your phone to locate your headset.
TIP: For most phones, select Settings/Tools > Connections > Bluetooth > Search > 8XXPlantronics. See your phone's user guide for more information.
- When prompted for the passkey, enter 0000.
When pairing is successful, the indicator on your headset turns off. Your headset is now connected and ready to use.
The Plantronics Voyager 855 headset comes with three sizes of sound isolating ear buds. We recommend that you try all three ear buds to find the one that fits snugly in your ear. For added comfort and stability, you can add the optional small or large ear loop stabilizer.
TIPS:
- For optimum performance and a secure and comfortable fit, the headset should sit snugly in your ear canal with the microphone pointing toward the corner of your mouth.
- If the ear bud is too big or too small, the headset may not stay in your ear, or you may have difficulty hearing.
PUT ON THE HEADSET
- Hold the headset with the boom pointing directly at your cheekbone and the ear bud placed comfortably in your ear canal.
- Gently twist the headset downward while pressing it into your ear canal.


TIP: For optimal voice clarity, point the boom toward the corner of your mouth. The ear bud should be fully seated to the speaker post to ensure secure attachment.
WARNING: Select an ear bud that inserts comfortably in the ear canal. The ear bud should seal but not be forced down the ear canal. If the ear bud becomes lodged in the ear canal, seek medical attention immediately.
CHOOSE AN EAR BUD THAT FITS
When the ear bud fits properly, it should be sealed in your ear so that you feel a slight amount of resistance when you remove the headset from your ear.
- Remove the headset from your ear.
- Gently twist the ear bud while pulling it off the speaker post.
- Press a different ear bud onto the speaker post with the stem side of the ear bud facing downward.
TIP: Try using different size ear buds on the headset and stereo plug-in cable. Do not assume that you need the same size for both ears.

USE THE STEREO PLUG-IN CABLE
You can use the stereo plug-in cable to listen to music in stereo.
- Insert the ear loop tab on the stereo cable into the slot on the under side of the headset until you feel it click into place.
TIP: You can attach the ear loop on either side of your headset, so that you can wear the headset on your right or left ear.
- Drape the stereo plug-in cable across the back of your neck so that the headset hangs over one shoulder and the stereo ear bud hangs over the other shoulder.

- Guide the loop behind your ear. Gently twist the headset downwards while pressing it into your ear canal.
- Gently press the ear bud on the stereo cable inside your other ear canal.
TIP: To remove the stereo plug-in cable from your headset, gently pull the ear loop straight out of its slot.


USE THE OPTIONAL EAR LOOP STABILIZER
For increased stability, you can attach the optional small or large ear loop stabilizer.
TIP: You can attach the ear loop stabilizer on either side of your headset, so that you can wear the headset on your right or left ear.
- Insert the ear loop tab into the slot on the under side of the headset until you feel it click into place.

- Guide the loop behind your ear.
- Gently twist headset downward while pressing it into your ear.
TIP: To remove the ear loop stabilizer from your headset, gently pull the ear loop straight out of its slot.

STEREO HEADSET CONTROLS
For stereo listening, your Bluetooth device must support the Bluetooth Advanced Audio Distribution Profile (A2DP) profile. The A2DP profile defines how Bluetooth devices stream stereo quality audio from one device to another. For example, music streamed from a mobile phone to a wireless headset.
If your Bluetooth device also supports the Audio/Video Remote Control Profile (AVRCP), you can use your headset to control music playback. For example, you can use functions such as pause, stop, next/previous track and volume controls. If your device does not support the AVRCP profile, then you must use the controls on your device to control music playback.
STEREO HEADSET CONTROLS
- Check your Bluetooth device's instruction manual to determine whether your device supports the A2DP and AVRCP profiles.

- To reduce the risk of electric shock, explosion or fire use only the supplied charger or Class 2 AC adapter to charge the headset. Ensure that the voltage rating (e.g. 120V , 60Hz ) corresponds to the power supply you intend to use.
- Do not disassemble the AC adapter as this may expose you to dangerous voltages or other risks. Incorrect reassembly can cause electric shock or fire when the product is subsequently used.
- Do not insert anything into the product because this may cause damage to the internal components or cause injury to you.
-
Avoid contact with liquids. Do not locate this product near water, for example, near a bath or sink, in a wet cellar or near a swimming pool.
-
Discontinue use of product and contact Plantronics if the product overheats, has a damaged cord or plug, if the product has been dropped or damaged or if the product has come into contact with liquids.
-
Exposure to high volume sound levels may damage your hearing. Although there is no single volume setting that is appropriate for everyone, you should always use your headset or headphones with the volume set at moderate levels and avoid prolonged exposure to high volume sound levels. The louder the volume, the less time is required before your hearing could be affected. You may experience different sound levels when using your headset or headphones with different devices. The device you use and its settings affect the level of sound you hear. If you experience hearing discomfort, you should stop listening to the device through your headset or headphones. To protect your hearing, some hearing experts suggest that you:
-
Set the volume control in a low position before putting the headset or headphones on your ears.
- Limit the amount of time you use headsets or headphones at high volume.
- Avoid turning up the volume to block out noisy surroundings.
-
Turn the volume down if the sound from the headset or headphones prevents you from hearing people speaking near you. See www.plantronics.com/healthandsafety for more information on headsets and hearing.
-
As with all corded products, there is a danger of strangulation if the cord or lanyard should become wrapped around your neck.
