I receive an error that the BT250 is not powered or out of range

Turn off the headset.
Hold the power/call button to make it discoverable.
Add it from your iphone using password 0000 or 1234

Good luck!

Connecting a Bluetooth headset or car kit You can listen to music over a Bluetooth stereo headset, or have hands-free conversations using a compatible Bluetooth headset or car kit. It's the same procedure to set up stereo audio and hands-free.

• For you to listen to music with your headset or car kit, the headset or car kit must support the A2DP Bluetooth profile.
• Before you connect your headset, you need to make it discoverable so your phone can find it. You can find out how to do this by referring to your headset manual.

1. From the Home screen, press MENU, and then tap Settings > Wireless & networks.
2. Tap Bluetooth settings.
3. If the Bluetooth check box is not selected, select it to turn Bluetooth on.
4. Make sure that the headset is discoverable.
5. Tap Scan for devices. Your phone will start to scan for Bluetooth devices within range.
6. When you see the name of your headset displayed in the Bluetooth devices section, tap the name. Your phone then automatically tries to pair with the headset.
7. If automatic pairing fails, enter the passcode supplied with your headset.

The pairing and connection status is displayed below the hands-free headset or car kit name in the Bluetooth devices section. When the Bluetooth headset or car kit is connected to your phone, the Bluetooth connected icon is displayed in the status bar. Depending on the type of headset or car kit you have connected, you can then start using the headset or car kit to listen to music and/or make and receive phone calls.

are you using a bluetooth headset? if yes then check whether u have switched on your bluetooth headset & also your phone & bluetooth headset must be reachable, that is, both should be within range as mentioned in your bluetooth headset manual.  

You may need to reset your Bluetooth devices. Please follow the steps below:

- Delete BT8040 from cell your phone. (if listed)
- Turn your cell phone off completely, and remove battery for 10 seconds. Please consult your phone provider prior to removing battery.
- Connect the BT8040 headset to the charger for 10 seconds then unplug.
- Place the battery back into your phone and power your phone on.
- Remove the headset from the AC cord.
- Turn off the headset by pressing the answer/end button until the light flashes rapidly then release.
- Press the answer/end button until you receive a solid blue light. This may take up to 10 seconds.
- Go into the Bluetooth menu on your cell phone and follow the cell phone’s instruction guide for pairing a Bluetooth headset. This generally involves going into a “devices” or “hands free” menu and adding a new device. Your phone may ask if you want to pair with the headset, accept by pressing “yes” or “OK” and confirm with the passkey or PIN 0000 (4 zeros).

switch off jabra. Hold down on/off button for sabout 10 secs until blue light is continuously on. Then pair from the phone. Pin 0000

To initiate pairing, put the devices within 0.5m of eachother

Make sure phone / pc bluetooth is on and discoverable
Make surea headset is fully charged

1. Ensure headset is switched OFF
2. Press and hold the talk button (big central button on front of headset) until the indicator flashes red & green alternately, then release. Headset now ready for pairing.
   Note: Headset pairing mode will time out after 5 mins.
3. To allow phone / pc to "find" the headset, consult your phone / pc bluetooth operating guide on pairing devices.
4. Headset should be listed on phone / pc after search has finished - highlight and select the headset.
5. A pin or password screen will appear, you must enter 0000 and confirm.
6. When pairing is successful, headset indicator will change to green and flash continuously every 3 seconds.

Pairing is then complete.

Note: Multi-pairing.
It is possible to pair up to two phones with the headset - the most recently paired phone becomes the "primary "phone... only one phone can be connected at a time --> this function only works in Hands-Free profile. If both phones are in range, then the headset will connect to the "primary" phone first.

you will need to go into the phones bluetooth devices and delete the Jabra headset and then pair it up again.

you need to hold the power putton some seconds longer when you turn it on, until it starts blinking in an other pattern...

had the same problem but this site reminded me to hold the phone button down 7-8 seconds. I was simply not waiting long enough - took more like 12 seconds.
