Re: problem with the head set

It requires a headset key to be programmed in Memory Block 4-12 as a type of Feature Access Key in order for the jack underneath the phone to work. Then you just press the button to speak via the headset.

First of all, make sure you're plugged into the headset port of the telephone and not the handset port. Pressing the Handsfree button should change from handset to headset. You can't use the speaker phone with the headset plugged in.

I am trying to use a plantronics headset system and cannot get a dial tone. Is this Norstar phone compatible?

You don't say what headset it is, but I will to help you.

If this is a Plantronics corded "H" series headset you will need to use an A10 adapter cord, which plugs into the headset jack on the phone.

If this is what you are using and you don't hear anything then you need to probably need to switch to an M22 amplifier box, which is then plugged into the jack where the telephone handset was plugged in.

If you are using a wireless headset it plugs into the handset jack where the handset cord was plugged into.

Good luck from Headsets Direct!

These phones are digital proprietary telephones which means that they only work on panasonic telephone systems and not on normal analog lines. If you have a panasonic system the correct way is to plug the line into the " To Main Unit ", the handset into " Handset/Headset" and a normal analog phone into " To Tel ". If the wiring on the line jack was not done digitally the phone will also not work

Problem using headset - why the handset has to be off hook

Be sure the headset you have is compatible with the Merlin Magix and a 4424 L4D+ phone. You will need to program both the headset status and headset hangup buttons. Headset status will negate the need for lifting the handset. and the hangup button is used to disconnect the call.

A headset

There is an adapter that will auto lift the reciever, otherwise you will have to manually hit speaker phone each time. As of the last time I worked on these types of systems there was no way without the lifter. Something like the lifter in here is needed

Have 2 t7316e nortel phones...i can hear the other person, but they can't hear me...tried swapping handset, but that didn't resolve the issue...any answers?

Look at the bottom of the set that is giving you troubles, check to see if the handset is plugged into the correct spot.

It should be plugged into the Handset jack not the headset jack.

This is a common mistake.

Headset on DTU 8D-2 corded phone

If you are using the headset jack on the phone, a headset key needs to be programmed on the the phone. You can do this in program mode and make a line key a headset key. Otherwise you must connect it through the handset.

A button must be programmed as a "headset" key. When activated, it will lamp red, and put the conversation on the headset jack under the phone (next to the handset jack).

Or you can purchase a headset with an auto lifter for the handset. It picks up the handset enough to answer the call, but transfers the conversation to your headset.
