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!

Avaya Partner ver 3.0 system. Intercom, Page over loudspeakers. Idustrial setting, volume must be high to be heard. When using extensions in shop area feedback is very high, making words unhearable,...

I suggest a headset. Avaya has a great headset selector tool at:

Just pick your phone model and options you want and it will drill down until you have a list of suitable headsets.

Let me suggest, for your environment, a corded headset, over-the-head with two earpieces, and noise cancelling. Either of the three models here:;PhoneModelName:Partner%2012B;HeadsetConnection:Corded;HeadsetStyle:Over-the-Head_esc_comma_%20Two%20Earpieces;AudioOption:Noise%20Cancelling would be great.

One phone is not working.

The issue here in "most caases not all is the battery is at its prime" i would first buy a new battery let it charge for 20 hours!! then try reregistering the headset. if that does not work or reregister then you know now you got a bad transmitter radio inside. Try all reset methods as well even before you spend $12 bucks on a battery pack. Chances are its the battery, worse comes to worse the headset needs to be replaced.

thanks this was a FREE solution please do be considerate and rate and leave postive feedback thanks.

Siemens Gigaset 4000 No Sound

Hi Krister,

It sounds from your symptoms (no pun intended) that your handset receiver/speaker has gone bad, or if you use a headset, the circuit might have gotten ripped open from tension from the headset plug. You can try plugging in a standard 2.5 mm plug headset into it (real common headset). My guess is that you will be able to hear dialtone using a headset and use the phone, but the phone will continue not ring or make key beeps.

Its fixable, but with the Siemens models don't let anyone try to open it. To work properly it needs to snap together tight, and guaranteed they will gouge the plastic and break the more than 10 tabs that keep it held snug together, there are no screws. The skill to open them without damaging them is proper training and muscle memory, which is reserved for the people that do it daily, plus if the plastic needs replacing it will add to your costs. Nevertheless, if you want it fixed, just google "Siemens Cordless Repair" and click the first or second non sponsored link to make arrangements to get it fixed. Good Luck and let me know if I was right about the headset audio.

Jennifer, if it is a CallBack Request, it will be cleared when you speak with the extension that set it. You can press SPEAKER - "#" to call them back (default setting).
If the phone is in CFWD ALL, clear it by pressing SPEAKER - "42"
