Plantronics CS55 We just upgraded phone systems, and now when I get an incoming call instead of a normal "ring...pause....ring" it's just a constant ring. I've been through the user manual and can't figure out how to change this function, and it's driving us all crazy!

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:

HL10 Nortel Adapter Kit - 46780-01

If 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:

Lowering the ring volume on the phone only decreases the sensitivity of the lifter, which generates the signal to the headset. The signal volume between the two is preset and cannot be adjusted.

You will need the Plantronics HL10 handset lifter in order to have the CS55 ring, indicating an incoming call. The HL10 also allows you to answer remotely on most phones and hang-up remotely.

We're had customers call with similar issues. First, make sure your compatibility dial is set properly (located on the side of the base). If set incorrectly, it will make your headset inoperable. If that doesn't fix your issue, try disconnecting and reconnecting the battery and then perform a subscription. Both steps can be found below:

The first thing to try is resetting the CS55. We hear this a lot and once reset, it usually takes care of the problem. It's equal to a ctrl+alt+del on a computer. Click on the following for detailed instructions and photos:

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.

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.

Only if you have an HL-10 lifter installed... you will then be able to hear three short beeps in your ear to indicate the phone is ringing.
