I have a Samsung wep420 Bluetooth headset but it won't charge in the doc. It's flashes red and blue and I don't know what to do. It won't turn on

1. Charge the headset:Headset is charged via USB cable, the light will be red when charging. When the battery is fully charged (about 2-3 hours), the red light of the headset will turn off automatically or the red light turns blue.
2. Turn on the headset:Press the on / talk button on the headset for about 5 seconds until the blue and red flashes alternately (or blue flashes or the blue lights all the time ), now the headset is ready to be connected to the iPhone.
3. Go to Settings, and tap Bluetooth. Turn on Bluetooth.
iPhone will automatically start searching for Bluetooth devices. Tap the device in the Devices list, then follow the onscreen instructions to connect to it. After matching successfully, the blue light on the headset will flash twice per time.
4. Call: when you finish all the above steps, you are going to talk via the Bluetooth headset. When there is incoming call, press the on / talk button, you can talk with Bluetooth headset, when you want to end the call, press the on / talk button, you can end the call.
5. Turn off the headset: Press the on / talk button for 5 seconds until the red light of the headset flashes quickly for twice, then release the button, the headset will be turned off.

Hi, Ephraim. The flashing red light indicates that the device is showing "low battery". It could be that the LG phone charger fits the charging port on your bluetooth headset but it is not compatible with your device. In order for you to know that it is charging, the device should show a steady red light(means charging).
Please take a look at the table reference below.

I don't know if you've done this, but before charging the headset, you want to turn it off. On the "Take A Good Look" page from the link below for the Plantronics M100 you'll see how to turn it off. If it's still not charging right, you may need to take it back to your retailer for warranty replacement or call Plantronics at 800-544-4660 x5 x5538 for warranty assistance.

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.

Please don't forget to rate me if satisfied.Thanks for choosing Fixya.Good Luck.

If you manually turn the headset off, make sure that it is by itself, no other phones in the area, no WiFi hotspots. Once this is done make sure that there is not a bluetooth already installed on the phone itself, if there is, delete it. Make sure that the headset has a full charge. Try the pairing again. If this still won't work, you can try Plantronics Tech service line 800-544-4660.

How to Pair Your Phone With Your Headset for the First Time

1 Turn on the Bluetooth feature on your phone.
For most phones, select Settings/Tools > Connections >
Bluetooth > On. See your phone’s user guide for more information.
2 Turn the headset on.
Turn on your headset by sliding the Power Switch toward the microphone. Wait until the indicator light flashes red then blue.
If you don’t see the red then blue flashes, turn the headset off, then turn it on again. Press and hold the Call Control button until you see the red then blue flashes that indicate pairing mode status.
3 Set your Bluetooth phone to ‘discover’ to locate the headset.
This usually involves going to ‘setup’, ‘connect’ or ‘Bluetooth’ menu on your phone and selecting the option to ‘discover’ or ‘add a device’.
4 Once available headsets are listed, select your headset (for example 2XXPlantronics or 3XXPlantronics). If prompted for a passkey, enter 0000.
When pairing is successful, the indicator on your headset flashes blue. Your phone will also confirm when pairing is complete.

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
