You need to probably change the batteries. If this doesn't work, make sure the frequency is set correctly. And if that doesn't work, contact your retailer.

Green light keeps blinking after charging it and i turn the powere on also teh sound comes and goes from one side of the headset


Blinking green light is an indication the headset is trying to establist communications with the receiver (dongle). Sound issues are normally on the side where the microphone is, this is most commonly a broken wire. The speaker wires are very small diameter. This can be fixed by a competent soldering job with new wirest from PC board to speaker inside the headset.

Red power light blinking on my denon avr 1907, tried reset procedure, no speakers hooked up now and it still goes from green light to blinking red light and shuts off...Any clues?


This is a protection mode. The receiver protection circuit detects an internal problem like missing power supply voltage or blown channel and shuts down the receiver. You need to bring the unit to a repair facility.

Does not charge when the charger is plugged. The Red light does not turn on.


Just wait for the battery to be completely drained-I did that to mine just now.after the battery is completely drained, I charged it, and it began functioning again.

Headsets receive no sound


if you have the headphones plugged directly into the audio out, then thats the problem. the audio only supplies a low volume, pre-amplifier output and this needs to be put through an amp of somekind to get a decent volume. Look for a headphone socket on the tv, usually near the s-video plug and coloured green.

All of a sudden my CS 55 with plantronics stopped working. It shows that its on but the headpiece isnt charing and also doesnt work. Any ideas why?


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.

4. Reconnect the AC charger.

Now give the Plantronics headset a try.

Green light stays on....headset not turning on


I have had no trouble with mine (3+ months of good use) until today. Same problem you had - green light won't go out, unit won't turn on. Jonsumer's solution got me to thinking, and this worked for me:

1. plug the charger into the wall.
2. plug the headset into the charger.
3. unplug the headset from the wall.

Plugging & unplugging the headset to charger multiple times had NO effect. It was only when I plugged it into the charger and unplugged the charger from the wall that the green light turned off and the headset began to work normally.

Plantronics cs55 problem


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.

Plantronics Problem with my headset


Setup the Plantronics CS60 wireless 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.

To be able to hear or speak through the headset, press the call control button on the side of the headset. The talk indicator light on the base should go on and the green light on the side of the headset should be blinking.

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

Hey, my rca whp141 is incredibly quiet. Go ahead and turn the volume up on the TV.
If that doesn't work make sure
  • The headphones and headset are on the same channel (like 1).
  • the transmitter is on and working (Power: GREEN LIGHT)
  • the headset is on and working (GREEN LIGHT)
  • the headset is receiving a signal (St: GREEN LIGHT).
Hope this helps.
