Question about Plantronics DSP-400 Headset

Open Question

Mute Button Stuck, red light won't go out when pressed.

The mute button always comes on when I start up my computer. So I click it off, no problem. But now, it seems to stay on. I suspect I might have on this last occasion pressed too hard. Of course I'm looking for a fix on this?

SOURCE: No speaking ability

The mute button on these is the little black button on top of the earpiece. It will only be on if you turn it on during a call. If you turn the headset off, the mute button goes off as well.
Check the compaibility 'wheel' on the side of the base station. The most common setting is 1 but some phones use 2,3 & 4. Just try it on each setting until it works. Other than that, check the microphone volume adjust setting underneath the base (ABCD switch) and see if changing that makes a difference. Of course there is always a small chance that the microphone is dead.

Try deleting the headset out of your phone and then re-pair it back up and see if that corrects the problem.

ProBook 6450b mute button on keyboard is always orange


Is the volume muted or not when the light is orange? If it is muted then use the icon on task bar and increase the volume, to see if color changes. If it is not muted and a change of volume does not affect the color of the light, maybe that is the normal color for it. Did you read the manual and find that orange means trouble. On my computer, the light for my WifI is always orange.
The speakers may be muted by an Fn +Fx key sequence, or some additional buttons on the computer.

    HP probook 4420s stuck on mute


    Look on you system at the keyboard and you will find a key that toggles the mute if he pressed it. It will toggle between on and off. Normally the mute key or button will look like a megaphone and if it is muted it will have an x over it. Press it to unmute it. Sometimes if it is a key, you might have to press the FN, CTRL or ALT key while you press and hold the key that toggles the mute.

    Another way to remove the mute is to Double Click on the megaphone if you see it at the bottom right near the time. This will bring up the volume control and you just remove the check mark from any that is muted.

    Also you can click Start/Control Panel look for volume controls that might be muted and remove the check mark on mute.

    Also click Start/Programs/Accessories/Entertainment/Volume Control and remove the check mark on muted items.

    My acer netbook is stuck on mute


    if the little x over the volume bar is still stuck after moving it up you may have to hit the function key (fn) on your laptop and hit one of the F1-F12 KEYS that look like a mute or volume symbol also there should be a mute button on the laptop itself. if all that fails. go to (xp) right click on my computer -device manager-and see if you have a red or yellow x over your sound sound devices (win vista or 7) go to computer, sys prop on the top then device manager. if you see any of htose yellow or red warnings you will need to re-download the audio drivers from acer website Let me know if this helped.
