Person on the other end receives a bad feed back when I am talki
I just put a CS55 Plantronics wireless headset with a HL10 lifter on my NEC phone and they people I am calling cannot stand the feedback they are getting when I talk. I know these will work because someone else in the office has the same system.

Re: Person on the other end receives a bad feed back when...
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.

The ring from the telephone is picked up by the internal microphone on
the HL10 Handset Lifter, typically for most phones, the lifter sits
directly over the speaker grill on the telephone where the sound comes
out. For telephones that curve out on the left side and don't have a
straight edge, there is an accessory called a "Ring Detector" which is
used. Here's a link:
the internal mic on the lifter has gone out, you can plug the ring
detector into the handset lifter and just stick the ring detector over
the speaker grill to pick up the ring. Plugging this into the lifter
will bypass the internal mic, this accessory would have come with your
HL10 lifter. You can also check the ring volume on the telephone, and
you can also try adjusting the ring tone on the phone (sometimes it will
pick up one ring tone better than another). Here is a link below if
you need to order a new ring detector: HL10 Nortel Adapter Kit 63014-01
The internal gears on the Plantronics HL10 may be worn. You can take
the handset receiver off hook and try manually raising up the lifter as
far as it will go and then slowly pushing it back down into place,
sometimes this will help to get it back working properly. If that
doesn't work, you may need to replace the HL10 lifter. Below is a link where you can purchase a new lifter.
I'm assuming you are using a Plantronics HL10 handset lifter. The
lifer is what notifies your headset that it has an incoming call. Try
turning the ringer volume up on your phone first and see if that solves
the problem. If that does not help, it could be the sensor on the lifter is going out. This could be causing a delay in the response time. The lifter
ships with a ring detector that has a 2.5mm jack on one end and a small
round microphone on the other end. 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 in picking up the sound of the
phones ring tones. If that doesn't help you might consider replacing
This how I fixed it 1) set bottom mic to A 2) set dial on the side of CS55 to "Setting 1" most typical 3) set sound lever on the back to "1" 4) played with mic control on the back until quality became sufficient
NOTE: Before re-subscribing the system make sure the IntelliStand switch (on the right side of the charging base) is in the "_" position and NOT the "=" position. To Re-Subscribe:
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.
If the Plantronics CS55 wireless headset shows that it is on, you have to make sure of the following things.
a. the green LED on the base turns on when you turn the call switch on from the headset. b. the small green LED on the side of the headset is blinking. c. the telephone headset is lifted from the cradle. d. if the headset is not charging and the Amber light on the base does not blink when you place wireless headset on it; trying placing the headset more firmly. e. If the headset is not charging and the Amber light on the base does not blink even after placing the wireless headset firmly on the charging cradle, you may need to change the battery.
Alternately you can try resetting the Plantronics CS55 wireless headset.
Reset Plantronics CS50, CS60 or CS55 Wireless Headset
If you have problems with the sound or connection of your Plantronics CS50, CS60 or CS55 wireless phone headset, you may want to try to hard reset it using the following steps:
Note: Ensure the IntelliStand switch (on the right side of the charging base) is in the - position and NOT the = position.
1. Press both the call control button and the listening volume/mute button for 5 seconds. When the indicator light blinks release both buttons.
2. Press the call control button again. The talk indicator light will again blink to indicate the headset is back to normal.
3. Disconnect the AC charger from the AC charging jack for 5 seconds.
Turn on the wireless headset as soon as the HL10 lifter picks up the headset. Remember to press the call answer switch. A steady green light should come on the base and the wireless headset should have a small green blinking light on, on its side.
* Make sure your hand receiver is off the hook when using the headset. Also check that you hear a dial tone on the handset/hand receiver before turning on the headset.
