CHARGING THE HEADSET
Connect charger cord into the headset's charging port. The MFB's indicator light may turn blue for several seconds while the headset determines the level of charge the battery is holding. Do not remove the headset from the charger. If the headset is not fully charged, the indicator will turn RED within a short period (less than 3 minutes). When the indicator turns blue—and stays blue—the unit is fully charged. It could take approximately 2.5 hours to achieve a complete charge.

ON / STANDBY / OFF
Turn Headset On: Hold down the MFB for approximately 2-3 seconds until you hear a voice prompt, "Power on." The blue light will flash twice every second.
Standby Mode: Once the headset is turned on (after the initial pairing), it will attempt to connect to the last device that it was paired with, putting itself into Standby Mode. (The headset can also be put into Standby Mode with a quick press and release of the MFB). The blue light will flash indicating an active Bluetooth link. The headset will give a voice prompt (in English), "Your headset is connected."
Turn Headset Off (conserves battery power): Hold down the MFB for approximately 3-4 seconds until you hear a voice prompt (in English), "Power off." A red light will flash 4 times and the headset will turn off.
PAIRING WITH A CELL PHONE
Keep headset and phone no less than 3 inches and no more than 3 feet apart while pairing. Keep other Bluetooth devices at least 50 feet away, or turn them off. NOTE: The headset can be paired with up to 8 different devices but can only be connected to one at a time. It can only switch back and forth between 2 devices in Multipoint Mode.
- Turn headset off.
- Press the MFB until the light rapidly flashes blue and you hear the audio prompt "Power On" (in English) and keep holding until you hear "Discovering" (in English). IMPORTANT: Wait for all audio prompts and the blue, rapidly flashing light. This may take up to 8–10 seconds. Release the MFB.
- Put your cell phone into Bluetooth Search/Scan Mode per the manufacturer's instructions.
- Wait while the devices discover each other: This could take up to 2 minutes. Once the phone discovers the headset, select "pair" and enter a passcode of "0000" if instructed. Once pairing is complete, the headset's rapid blue light will stop flashing and the phone may prompt you to 'connect' to the headset. Enter "Yes" on the phone if prompted to connect to the headset. When connected, you'll hear the voice prompt (in English), "Your headset is connected," and the blue light will flash slowly (once every 3–4 seconds), indicating that the headset is in Standby Mode and ready to make or receive calls.
PAIRING WITH BT2 USB ADAPTER
Your VoxStar UC headset is pre-paired with the BT2 USB Adapter. If you need to re-pair your headset, or pair the BT2 with a different headset, follow these steps:
- Place the headset into pairing mode.
- Insert the BT2 into a USB port on the computer.
- The adapter will initialize and enter pairing mode while the computer installs any necessary driver files. The BT2 LED will flash quickly. The headset should connect with the adapter either during initialization or shortly after. Note: If the adapter and headset do not pair the first time, unplug the adapter and repeat this procedure.
Make sure your PC's sound settings have the VXi BT2 USB Adapter as the default microphone and/or speaker. Go to www.vxicorp.com/usb for more information on configuring your specific operating system.
MULTIPLE DEVICE PAIRING
The VXi VoxStar UC can pair with up to 8 devices at the same time; however, only one device may be connected to the headset at a time, unless the headset is in Multipoint Mode.
Once all devices are paired, the headset will connect to the devices in reverse order of pairing. For instance, if device A, B and C were paired in that order, connection will be established to C first. If C is not available (turned off, out of range), the headset will connect to B, etc.
MULTIPOINT MODE
Multipoint Mode allows you to pair and switch between two Bluetooth devices.
The headset can be paired with devices before or after enabling Multipoint Mode.
ENABLING MULTIPOINT MODE
- Make sure any other Bluetooth devices are powered off or out of range.
- Power on the headset, but release the MFB as soon as you hear the voice prompt (in English) "Power On." The headset should not be connected to any other devices and should display a double-blinking blue light.
- Press and hold the MFB, Volume Up and Volume Down buttons, and then release all three at the same time.
- If successful, you should hear a 4 rising tone "fanfare."
- Power off the headset. It is now in Multipoint Mode.
- If you have not already done so, pair the headset with the devices you want to use.
- Once all this is completed, when you next power on the headset, you should hear the voice prompt (in English) "Your headset is connected" as it connects to each device.
MULTIPOINT MODE
DISABLING MULTIPOINT MODE
Disabling Multipoint Mode does not affect device pairings.
- Repeat steps 1–3 for enabling Multipoint Mode.
- If successful, you should hear a 4 descending tone "fanfare."
- Power off the headset. Multipoint Mode is now disabled.
PROXIMITY PAIRING
Proximity Pairing enables the headset to find the closest "discoverable" phone.
- Make sure the headset is powered on.
- Hold the MFB down and quickly press the Volume Down button.
- You should hear the voice prompt "discovering" (in English) in the headset.
- The headset lights will rapidly flash blue.
- The headset initiates pairing activity, and the user has to accept the incoming pairing invitation on the phone. NOTE: This may include entering the pin number "0000" (four zeros).
MAKING A CALL
If you have not paired the headset and phone together yet, you must do so.
- Turn on your cell phone. Be sure the Bluetooth option is enabled on your phone (refer to your phone's user guide for instruction).
- Put headset on and properly position the microphone. Turn the headset on, and wait for it to connect to your phone.
- Dial the phone and make a call as usual. Or use the headset's Voice Dial function (if your phone supports it) to make a call.
- To end call, quickly press the MFB on the headset and release. You will hear falling tones. The call will end and the headset will enter Standby Mode.
ANSWERING A CALL
In order to answer a call, the headset must be in Standby Mode.
- When your cell phone rings, you will hear ring tones in the headset. Answer the call by quickly pressing the headset's MFB and release. You will hear 2 rising tones (and the MFB button will blink blue every second).
- To end the call, quickly press the MFB on the headset and release. You will hear falling tones and the headset will enter Standby Mode.
The VoxStar UC headset will operate from battery power or from the AC/DC charger/adapter.
NOTE: Do not attach the charger mid-call. This will cause the headset to reset, and the call will be sent back to the phone.
When the headset is operating from the battery, all indicator lights and sounds will function as described in this guide.
When the headset is operating from the charger/adapter, the headset—including the audio indicators—will function as described in this user guide. However, the MFB lights will indicate the battery charge status.
While the headset is on the charger, press and hold the MFB long enough to power the unit on. The headset should reconnect automatically unless your phone is set to “always ask” for connection requests.
After the battery is fully charged, the MFB charge light will turn and stay blue. As long as the charger/adapter is connected to the headset, the indicator light will remain blue.
ADDITIONAL FUNCTIONS
