My Telex Headset receives but does not transmit.

Don't know why answers for different type of headsets shown up on a question about the Telex 850. Probably there is an issue with the cord. The cord has two shielded "double" wires on each pair. The ones for the mic are "white" and "light blue". May be one is cut preventing the mic to work. Look around for a local avionics shop, they should be able to fix it. Hope this helps ;)

The following is a cut from Plantronics web site. I hope it helps, It's just possible you have missed a setting, such as the mute switch.

The CS50 has both transmit (how you are heard) and Receive (how you hear) controls on the unit itself.

The Master Transmit controls are the ABCD switch settings on the bottom of the base. A is the lowest and D is the highest setting. You can fine tune this setting with the Plus (+) and minus (-) buttons on the back of the base that are above and below the picture of the microphone.

The Master Receive setting is on the back of the base (below the picture of the microphone) there is a 1234 switch 1 being the highest setting and 4 being the lowest setting. You can fine tune this setting by using the volume control on the headset itself. This is the rocker volume wheel on the back of the headset (opposite of the microphone).

The headset volume control also doubles as a mute switch if you press it in, instead of rocking it back and forth.

There are also configuration settings on the left hand side of the base. This is a dark grey dial with a 1234 on it. There are notches to the right of this dial. Whatever number is lined up with the notches it what setting you are on.
This needs to be set to the clearest setting.

There is a silver button on the headset itself which is your “Talk button”. This is what you press to use the headset and or transfer the call from the headset back to the hand receiver.

There is also a switch on the right hand side of the base which is your the IntelliStand feature.

When the CS50 is used in conjunction with the HL10 handset lifer you can enable the IntelliStand feature.

The IntelliStand feature senses when the headset has been removed or placed into the CS50 base unit which automatically activates the Handset Lifter and enabling headset/handset mode to answer or end the call.

There is a switch towards the bottom on the right side of the base unit that will switch the IntelliStand feature On and Off.

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.

The headset you bought will work with the Centracom Gold Elite but the older Series II may not work. Have you tried Plantronics assistance. They are very helpful and will support the product.

First setup the headset as follows:

• Locate the 2 ports on the bottom of the CS60 charging base. One has an icon of a "full telephone" and the other has an icon of a "hand receiver."
• Unplug the hand receiver from the base of your existing telephone and plug it into the "hand receiver" port on the CS60 base unit.
• Then take the short cable that came with the CS60 and plug it into the "full telephone" port on the base of the CS60.
• Plug the other end of the short cord into the hand receiver port of your telephone (where the hand receiver just was).
• Make sure the AC Power is plugged into the wall, and then you can adjust the configuration settings.

To be able to hear or speak through the handset, either place the headset back into its charging cradle or press the call control button on the side of the headset. The talk indicator light on the base should go off and no sound will come through the headset.

Note: Make sure that the cables are connected correctly and the handset cable is connected to the base of the CS60 base.

This may be caused by a few things.

1. Check the configuration dial on the left hand side of the base to see if another setting works better. The recommended setting for most phones is 1.

2. Make sure your speaking (transmit) level is not too high. First, try lowering the volume on the telephone. If you still hear distortion, adjust the volume of the headset. The master transmit controls are the ABCD switch settings on the bottom of the base. A is the lowest and D is the highest setting. You can fine tune this setting with the Plus (+) and minus (-) buttons on the back of the base that are above and below the picture of the microphone.

3. Double check the battery has a full charge.

The Amber Charge light on the base will flash while charging and will stay solid amber when fully charged.

3 hours = full charge

4. Make sure the headset has been paired to the base.
