The headset mode is on, but I don't settle it and can not turn it off so I have to use headset all the time. Once I restarted the phone, and it came to normal. But recently the battary came died and after the phone got filled, the problem with headset mode appeired again. Phone restarting doesn't help. What should I do?

The first thing I'd suggest you do is to turn your cell phone off and, if possible, remove its battery for 10 to 15 seconds. Then replace the battery and turn the phone back on. If taking the battery off the phone is not possible, simply delete everything on the Bluetooth pairing memory. Also, we will need to reset the Jabra headset to the factory settings.
Turn the headset ON. Then press and hold the volume down and answer/end buttons at the same time for approx. 5 seconds until the battery icon and Bluetooth® icon flash 5 times simultaneously - then the pairing list is reset.
Turn the headset OFF. The next time you power on, the headset will go into pairing mode as the first time you powered your new Jabra headset on.
Once in pairing mode, your cell phone should be able to add the Jabra headset as a new device from within its Bluetooth menu.

Normally Peltor headsets work as follows:

1.) Turn the device off.
2.) Once off, hold the on/off/mode button for 5 seconds until you hear a voice say "pairing mode"
3.) Make sure bluetooth is active on your device and search for the Peltor headset, once you find it select it.
4.) When prompted for a pairing key use 0000
that is 4 zeros.
5.) Headset should say pairing complete.

As with moth bluetooth devices remember this muse bt done within a normal amount of time so have your device ready to search by time you put headset in pairing mode will help.

Pairing the Headset
*You are required to pair the headset with your mobile phone or other device before using it.
1. Ensure the headset is off, then press down the P2 button until the pairing mode (both Blue & Red-LED's are flashing
alternately), then release. This will take about 6 seconds.
2. Initiate pairing process of your mobile phone. Refer to the manual of the mobile phone for the direction. You will see a new
item "BT headset" added in your Bluetooth device list after the searching process.
3. You will be asked to enter a pin code to complete the pairing. Enter 1234 and confirm. (Note: the 1234 is a default pin code
pre-stored in the Headset) The red indication will turn off and the blue indicator will flash slowly after the paring is completed
successfully.
4. Once the pairing is complete, the Red LED will turn off and the Blue LED will begin blinking, (indicating standby mode). If it is
not finished paring within 2 minutes, the headset will go into standby mode, and pairing is unavailable. You will need to restart
and repeat steps 1-3.

Please follow the correct instructions below to successfully pair your headset with the phone.Make sure that the headset is sufficiently charged before pairing.

Charge the battery
Before using your headset, charge the battery for at least 8 hours. Charging the battery completely (and keeping it charged) will help you get the longest possible talk and standby time out of the battery.

Pair the headset to your Bluetooth phone
Pairing is like "introducing" two Bluetooth devices and giving them permission to connect to each other. If you want to use the headset with more than one phone, you need to pair it with each phone separately. Once a phone and the headset are paired, they can connect automatically whenever they detect each other.
1. Make sure the headset is powered off and the power adapter is not connected (you can't use the headset while it's charging).
2. Press and hold Power until the LED flashes alternating red and blue. The headset is in pairing mode and should be visible to other Bluetooth devices.
3. On your phone, start a search for Bluetooth headsets or handsfree devices. (This process may take several seconds, and it will be different for each phone; see your phone's manual for detailed instructions.)
4. Your phone should discover a device called a BT108, BT108 headset, BT109, or BT109 headset, When your phone asks if you want to pair with this device, answer yes.
5. When your phone prompts you for a PIN code or password to pair with the BT108 or BT109 enter 0000.
6. When the headset is paired, the LED turns blue and flashes every 3 seconds. Your phone might display a confirmation message, also.
7. Your phone might ask if you want to change the headset's name; generally, you should only change the name if you have more than one BT108 or BT109 headset that you use with this phone.
Connecting to your phone
Most phones connect to the headset as soon as you pair it; if yours won't, turn the headset off and back on. If headset still won't connect, check your phone's owner's manual for additional Bluetooth information.
Once the headset is paired:
Whenever you turn the headset on, it will automatically try to connect to whatever device it was connected to last.
If the headset loses the connection (e.g., if your phone is out of range), it reconnects automatically. To manually reconnect, press Power.
If the headset goes more than 1 hour with no connection, it automatically turns off.

Did you do the steps listed here?
This is the Plantronics information.
Your new headset includes Plantronics QuickPair technology to simplify
the Bluetooth setup process. The rst 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 sucessfully paired after 10 minutes, your headset automatically
powers o. 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 rst 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
ashes red/blue to show that the headset is on and in pairing mode.)
TIP: If you don’t see the red/blue ash, press and hold the call control button to
turn your headset o, and then press and hold the call control button again until
you see the red/blue ash.
Use the commands on your phone to locate your headset.
TIP: For most phones, select Settings/Tools > Connections > Bluetooth >
Search > 520Plantronics. 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 ashes blue. Your
headset is now connected and ready to use.

passcode = 0000 (4 zeros) USER GUIDE

The first time you turn on the headset it will enter "Pairing" mode. In this mode you can connect your headset with your phone or other Bluetooth enabled device. If you have already connected one device to the headset, you can enter Pairing mode by holding the multi-function button turns solid blue.

Once in pairing mode, set your phone or other Bluetooth enabled device to search for the headset. While each device is different, the setting is often found in a "Settings" or "Bluetooth" menu and the "Search" or "Discover" Bluetooth devices option. On the list of discovered devices, choose "Samsung WEP500" and select "Yes" or "Ok" to connect to the device. When asked for the passkey, enter 0000.

had same problem with this headset on two phones and finally solved it.

1. make sure bluetooth on phone is activated (know that sounds silly but some people forget)
2. with the headset turned off, press and hold the on/off button on the headset until the light on the headset FLASHES CONTINUOUS BLUE AND RED (about 8 seconds). This is most important, because if lights on headset are not continuously flashing blue and red, the headset is not in discovery mode.
3. once headset is in discovery mode, go into "my devices" on bluetooth menu on phone and click to search for new devices. make sure phone and headset are close together. phone will say searching- BE PATIENT, THIS STEP TAKES THE PHONE SOME TIME. eventually phone will show that it found your headset.
4. once the phone lists the headset, click on the headset and tell the phone to connect to the device. at this point the phone will bring up a passcode screen. enter 0000, and tell it to connect. when it connects, the lights on the headset will automatically go to an intermittent blue. you should be all set.

the biggest mistakes my kids made trying to pair these headsets were:
1. failing to turn bluetooth on for the phone
2. turning the headset on in something other than discovery mode (continuous blue/red flashing lights)
3. not being patient enough to wait for the phone to find the device.

hope this helps
