I Can`t switch my headset on, and it stops charging after 20 secs

Try these steps from the user guide and then pair up your headset to the phone. "Before using, you must first charge your headset. 20 minutes = minimum charge. 2 hours = full charge. Light is solid red when battery is charging. Press the control button for 2 seconds to power on. Press the control button for 3 seconds to power off." If you're still having problems, then it's time to get a new one, sorry.

Good luck from Headsets Direct!

I was searching for this today and happened to find the above on the plantronics website. It definitely frustrated me till I found out about how to put the base in pairing mode.

The following are for TB-20EL model. But it works in general for plantronics as well. For step 3 make sure your headset is in pairing mode. When you hold the button 6-8 sec, it should turn either solid blue or blink.
for tb-20el:
1. ensure that your phone's bluetooth feature is on
2.Ensure that the headset is off(press and hold button on your headset (called multifuntcion button) for 2-4 sec, teh indicator light will flash red)
3. press and hold the multifunction button for 6-8 seconds until the indicator light alternately flashes blue and red
4. set your phone to find new device
5. Ente rpin '0000' (four zero) then press OK or yes
6. this should complete the pairing.

I am personally using a Plantronics CS60 wireless headset with a Meridian Nortel M2006 Phone and it works just fine.

Here is how you can setup the Plantronics CS60 wireless headset.

NOTE: Before setting up the system make sure the IntelliStand switch (on the right side of the charging base) is in the "_" position and NOT the "=" position.

The headset and the base unit are supplied subscribed to each other. However, if you wish to use a replacement headset with the base unit (or if you lose your connection to the base unit), then you must re-subscribe as follows:

1. Return the headset to the charging base.

2. Press and hold both the + and - buttons on the back of the charging base until the red light on the front of the base starts to flash.

3. Let go of both buttons. The red light should continue to flash.

4. Press the mute switch (black wheel on the top of the headset) straight down until a green light appears on the headset, then let go of the wheel, and the light should remain on the headset.

5. Resubscription is finished when the red light on the base is fully illuminated and the green light on the headset disappears.

6. Remove the headset from the charging base lift telephone handset/press headset button if not using a handset lifter. The headset and base should now be connected.

If the Plantronics CS55 wireless headset shows that it is on, you have to make sure of the following things.

a. the green LED on the base turns on when you turn the call switch on from the headset.
b. the small green LED on the side of the headset is blinking.
c. the telephone headset is lifted from the cradle.
d. if the headset is not charging and the Amber light on the base does not blink when you place wireless headset on it; trying placing the headset more firmly.
e. If the headset is not charging and the Amber light on the base does not blink even after placing the wireless headset firmly on the charging cradle, you may need to change the battery.

Alternately you can try resetting the Plantronics CS55 wireless headset.

Reset Plantronics CS50, CS60 or CS55 Wireless Headset

If you have problems with the sound or connection of your Plantronics CS50, CS60 or CS55 wireless phone headset, you may want to try to hard reset it using the following steps:

Note: Ensure the IntelliStand switch (on the right side of the charging base) is in the - position and NOT the = position.

1. Press both the call control button and the listening volume/mute button for 5 seconds. When the indicator light blinks release both buttons.

2. Press the call control button again. The talk indicator light will again blink to indicate the headset is back to normal.

3. Disconnect the AC charger from the AC charging jack for 5 seconds.

4. Reconnect the AC charger.

Now give the Plantronics headset a try.

Make sure the headpiece is charged. Turn the headpiece off by pressing the little black button on top of the earpiece and holding for about 5 seconds. Turn the earpiece back on again the same way. You should have a slow flashing blue light on the mic boom. The base station will now try to find the earpiece and within about 20 seconds the red light on the base should be steady and blue light on top should be on.
If this doesn't work you may need to manually pair the earpiece to the base by pressing and holding the Listen Volume Adjust + Button and headset Call Control Button on the earpiece until the light on the mic boom flashes red and blue repeatedly. As above, the base station will now try to find the earpiece and within about 20 seconds the red light on the base should be steady and blue light on top should be on.

When it is turned off, hold the main button in for 4 seconds until the light flashes red, the release. It should flash red and blue. This means it is in pairing mode.

I have the same problem. the blue light doesn't go away neither if I press the button to switch the headset off nor if i push id for a long time

When you hang up from calls you are holding in the button for more than 2 seconds...This is way too long and it shuts off the headset. When you hang up, all you have to do is press the button quickly, until it clicks, and the call is disconnected. Anything more than a second or two will turn off the headset, as explained in the manual. Holding it in when a call comes in will make the phone "ignore" the incoming call. Again, all you need is a quick push of the button until it "clicks" will answer the call, the same as hanging it up. I hope this helps you!

MIne connects to my phone and tells me it is connected but i do not get the headset picture on my mobile anymore, and when i make calls it isnt connected I still have to pick my phone up and use that..
Why should I have to do that when I bought it for that specific reason, I bought a Blueant one and it works perfect for three months..

Fix you problems plantronics and STOP using computer generated feedback!!!
And get someone with more than half a Brain to sort this out.
