Plantronics 200 earpiece

Well first turn your phone's bluetooth ON Then turn ON your headset.Wait for the indicator light to turn from red to blue. (if it doesn't turn off your headset then turn it back on) Press and hold the Call Control button until the indicator light flashes red and blue. (meaning it's starting to pair) Set your phone to find/add bluetooth device and select your headset from the list found When pairing is successful the indicator light should turn blue and your phone will confirm the pairing.

hope that helps....

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.

Unplug the AC power from the Plantronics 500A base, leave it unplugged at least overnight if possible, no lights should be illuminated on the base. Then plug the power back in, charge the headset, and try re-pairing the headset to the Plantronics 500A base unit. Here is the link for the pairing instructions:

I am sorry to say but the Plantronics are cheap and not well made. Sounds like you might have a weak battery and because of that it wont have enough charge to turn on. I myself have gone through many and now spent a little bit more and got a better earpiece.

turn on your cell; go to settings; find bluetooth settings;turn on bluetooth; find audio device choose search; then turn off the earpiece the light will be red next: turn on the earpiece again the light will flash blue and, the cell will find the earpiece the earpiece will flash blue slowly; once a minute
close the cell; use the earpiece

The headset will automatically pair with the last device that it was paired with. You may want to remove that just in case. I am sending the users guide along with this. Also always start with the blue tooth turned off, the pass key is 0000 (four zeros).

The 500A base station is definitely compatible with the 510 earpiece. If the earpiece is turned off or unpaired the base station's red power light will be flashing. If the earpiece is already off, try turning it on by holding down the little black button on top. The base station will automatically try to find the earpiece and the blue light on top of the base will come on. If the earpiece is already on (slow flashing blue light on the mic boom) turn it off and back on again and wait for the base to find it.

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.

With these units, if the earpiece battery is allowed to run down, it will switch off. When the earpiece turns off the base station starts to search for it, which is indicated by the flashing red power light. Also the blue light on the top of the base will turn off. The first step, which you have already done, is to charge the earpiece. Next, hold down the little black button that is on top of the earpiece for about 5 seconds. You should get a slow flashing blue light on the mic boom. Wait for about 10-20 seconds and the base should automatically find the earpiece. The red power light on the base will be steady and the blue light on top of the base will come on.
