Question about Panasonic KX-TGA520M Cordless Expansion Handset

1 Answer

How do you take it apart?

We're getting crazy feedback when we try to use the hands-free headset. I think it was caused when it was dropped and the headset was still plugged in. This bent the plug on the headset and did who knows what to the socket. I want to take it apart and take a look at it. I removed the two screws at the bottom of the unit (under the battery cover) but when I try to pull it apart something is still hanging up but I can't figure out what it is. Help!

Logitech speaker feedback

Feedback is a sharp, loud noise that can come through the earphones of a headset unexpectedly---it occurs when the headset is getting sound (feed) from someone else speaking or playing music into a microphone. This sound can create a dangerous situation for someone who is operating expensive equipment or flying a plane at the time since it can disable hearing temporarily.
If you experience feedback often, it could also lead to serious hearing problems.

Mic Too Close to the Speaker or Volume Too High
The main cause of a feedback sound in a headset is proximity to a speaker. If a person holding a microphone on the other end gets too close to a speaker, it creates a loop of re-amplified sound that results in the loud, screeching noise. When the volume on the other party's microphone is too high, it is more vulnerable to picking up unwanted noise and feedback from speakers and sound output devices in the room. So make sure that you ask the other party to turn down the microphone to a normal level and stay far from speakers. b> Two Microphones Gathering Same Sound b> When the other party places two microphones too close to each other, it could cause feedback. When positioned toward the sound source (such as a person speaking) the microphones will both pick up the same audio and compete with each other when creating the output of sound, causing a sharp noise in your headset. This problem, called acoustic phase interference, is resolved by simply ensuring that the other party uses one microphone at a time. Poor-Quality Headset or Microphone b> One common cause of feedback is simply a poor-quality headset or microphone. Most modern headsets and microphones have noise-canceling features that manage and kill feedback before it has a chance to occur. These noise-canceling headsets are essential for pilots and aviation crew members. If you hear sudden feedback that is strong enough to hurt your ears, the headset or microphone is simply not properly equipped to actively cancel that unwanted noise before it hits your ears. Buy a higher-quality noise-canceling headset to manage the feedback noise when you're going about your tasks. Hope this helps.

I am trying to connect my T305 portable bluetooth car speaker phone to work with my iPhone 3G, but I keep getting Motorola T305 not paired What should I do?

Hold the power button in on the speaker system until the indicator light turns purple. Have your Iphone scan for bluetooth devices and select the T305. The first time it connects it will ask for a security key which should be 0000. If that doesn't work try 1234 as well.

At that point it should pair successfully and you should be good to go.

Please leave feedback if you found this helpful. Thanks.

Dropped the blue tooth in my coffee, can it be taken apart to dry. It does not turn now.

Seriously it may be time to buy a new one.
But you have little to lose.
Try prying the body apart with a sharp knife edge.
If you can get it open, wash it in water to get the coffee out.
Water warm to the touch is ok.
Leave it in a warm dry place like a sunny windowsill for a week or so.
Reassemble it, give it a good charge and see if it works.
It may well, electronics are not as delicate as some people think.

I am getting feedback with Plantronics CS70 Wireless Headset

Echo is usually caused by the transmit (speak) level on the unit being set too high.

1. First, try lowering the volume of the telephone. If you still hear an echo, adjust the volume of the headset itself.

2. The master transmit controls of the headset are the ABCD switch settings on the bottom of the base. A is the lowest and D is the highest setting.

3. You can fine tune this setting with the plus (+) and minus (-) buttons on the back of the charging base.

4. If this doesn't fix the echo, try moving the configuration dial on the left side of the charging base. The recommended setting for most phones is 1.

Problems with my motorola hs850

Set your volume to mid range. If it continues you'll need to return it or exchange it. The voice pickup sencer in the bluetooth is defective. Or the phone needs an upgrade.
