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.

How to connect the planronics plx500 to the phone? what is the use of each one of the bottoms?


Unfortunately finding life on another planet would be easier than locating an ancient (electronic years) PLX-500 user guide. However, I happen to have one of those ancient writings (no, it wasn't in a cave at the Dead Sea), albeit a bit tattered and yellow, so I'll try and give you a rundown of it's various features.
The top buttons for headset/handset and mute, and listening volume wheel are pretty self-explanatory. Now let's talk about connecting the PLX-500 to your phone and the other amplifier features.
1) Disconnect the telephone handset cord from telephone base and insert the PLX-500 modular plug into the handset jack on the phone. You then insert the coiled handset cord into the back of the PLX-500 base (there's only one place it can go into).
2) Plug the cord from the headset into the jack in the front of the PLX-500.
3) On the back of the PLX-500 base there are two switches (1-2 and 3-4). These are used to configure your PLX-500 to your phone (most electronic single and multi-line phones, such as Panasonic, will use setting 1 and 4). You will have to configure the PLX-500 to your specific phone. Having connected your PLX-500 to your phone, put on your headset, press the headset button on the base, lift the handset of the phone cradle and listen for a dial tone. Adjust the switch settings until you hear the best dial tone.
4) Remember that your PLX-500 uses batteries located under a cover on the bottom of the base (some phones will work without your PLX-500 needing batteries, check configuration before installing batteries). Speaking of the cover, there is a small plastic screwdriver attached to it that you use for adjusting the volume of your microphone. That adjustment is located on the back of the PLX-500 base next to the configuration switches.
Hopefully this gets your PLX-500 up and running.

Good luck from Headsets Direct!

When I push the button on my head set to answer a call the lift thing lifts the reciver cut i cant hear anything, it stays on intercom and does not let me hear a line....


Wireless units using a handset lifter need to connect to the phone through the handset jack of the phone. That's one thing to check. Also, you want to make sure the round compatibility dial on the left side of the base is set correctly (normally #1 at the 3 o'clock setting to match indicator ridge).

Hi, At the office we have a Mitel IP phone we have just bought a headset model JAC0021201- B. We cant get it to work. Please can you advise how we set this up. Regards Trevor


I'm not finding manufacturer detail on this headset, only sales via Amazon, and it's dicey info at that.

So,I'm not certain this headset is compatible.  The only Mitel approved headsets are the Plantronics Polaris models.  These headsets fit into the headset port.  Such headsets require a headset button to be programmed and enabled on the phone to work.  When the phone rings, you will have to press the ringing button, to hang up, you will have to press the cancel button.

Other headset models may work, but require them to be plugged into the handset port and the existing handset will have to be plugged into it's unit.  Such units will require lifting the handset to answer the call and hang it up when completed.  Some such units have an optional lift kit.

I personally use a Plantronics Polaris "in the ear" model.  Plantronics web site has a config guide that will help you select a headset.

Plantronics cs60 cordless headset not working properly with Mitel 5220 ip phone. Cant switch between handset and headset. When you lift the handset sound comes from the headset. The same headset works fine...


I'm sorry for being long on my answer here...
The bad thing here is that the CS60 is not a Mitel approved/supported headset. The only headsets that are approved for Mitel Superset or Mitel IP telephones are the Plantronics Polaris model.

BUT many other headsets do work with Mitel telephones. Since they are not "supported" by Mitel, you should contact the headset manufacturer for configuration guidance. Some have dip switches, or dials that need to be in certain positions to work with certain telephone models. This can be different from one phone to another.

Plantronics web site and their support people should be able to guide you to configuring this headset properly for each model phone.


How is the headset and handset connected? It sounds like the CS60 is connected to the handset port of the phone and the handset is connected to the CS60. When you go off hook with the handset, it sends the signal to the CS60 and depending on the switch on the CS60, it will send the signal to either the handset or the headset.

OR

The CS60 is connected to the handset port and the handset is connected to the headset port. To make the headset port work, you must have the CS60 connected to the headset port and the handset connected to the handset port. Set the phone to Headset mode.

Cannot hear phone ringing in headset, only on handset.


The HL10 handset lifer is what notifies your headset that you have an incoming call. If you are using the handset lifter and are not receiving the 3 short beeps in your ear piece there are a couple different things that could be going on.
1. The internal microphone could have gone out on the lifter. This microphone is what sends the signal to your headset that you have an incoming call. If the microphone is working you will hear 3 short beeps in your headset.
2. If the volume is too low on your telephone, the handset lifter will not notify the headset of an incoming call, so try turning the volume up on your phone and see if that takes care of the problem.
3. The HL10 handset lifter ships with a ring detector that has a 2.5mm jack on one end and a small round microphone on the other end. This ring detector is intended for phones that do not have the speaker located under the handset. You could try plugging this into the back of the lifter and setting the microphone next to where the lifter is mounted on your phone. This might help pick up the sound of the phones ring tone.

If you are manually lifting your handset out of the cradle and sitting it to the side instead of using a lifter, then you will not receive the 3 short beeps in your earpiece to notify you of an incoming call.

Everytime i hit the blue button on the desk set i don't hear a dial tone in my head piece


Two things to remember. If you're connected through the handset jack, the handset (receiver) needs to be lifted off the phone to get a dial tone. Secondly, if you're connected through the headset jack, you may need to adjust the configuration dial (round dial on left-hand side of base) to make it work when the headset button on phone is pushed.

My Headset does´nt have dialtone, I was connecting to cisco phone 7941, 7970, 7911, and nothing, not work.


You can use a Plantronics S11 headset with a Cisco phone, however it is not the best compatible solution. To use an S11 with a Cisco phone, you have to make sure that you are plugging it into the handset receiver jack and not the headset jack. You will need to lift the handset receiver, set it off to the side, and then hang it up after each call. If you want a more compatible solution that you can plug into the actual headset jack and just press the headset button on the telephone to answer and hang up, then you would need one of the Plantronics "H-series headsets" with the Plantronics Cisco direct connect cable ( model 26716-01 ).

Plantronics CS55 requires lifting handset on phone


Please note that your hand receiver has to be off the hook when using the headset.

This is correct, additionally you can use a handset lifter accessory, such as the HL1 or HL10.

Subscribing Headset to Base:

The headset and the base unit are supplied subscribed to each other. However, if you wish to use a replacement headset with the base unit (or if you lose your connection to the base unit), then you must re-subscribe as follows:

1. Return the headset to the charging base.

2. Press and hold both the + and - buttons on the back of the charging base until the red light on the front of the base starts to flash.

3. Let go of both buttons. The red light should continue to flash.

4. Press the mute switch (black wheel on the top of the headset) straight down until a green light appears on the headset, then let go of the wheel, and the light should remain on the headset.

5. Resubscription is finished when the red light on the base is fully illuminated and the green light on the headset disappears.

6. Remove the headset from the charging base lift telephone handset/press headset button if not using a handset lifter. The headset and base should now be connected.

7. If this procedure does not resolve your issue to try a system reset.

Unable to connect jabra t5330 to a cisco ip phone 7941G headset jack


You can solve this by connecting your phone inline.
On the back of the phone where the phone handset plugs into, plug one end of the jabra headset wire & connect other end to the 2nd position (marked by phone & handset). Now plug the handset wire from Ip phone to the 1st position (marked by handset) in the jabra headset. Now you are good to go.

When the phone rings lift the phone handset and answer it with your jabra headset. You can't use jabra with 7941 without lifting the handset on phone.

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.
