The Problem: I have had my Plantronics CS55 wireless headset & HL10 handset lifter for several weeks now, and they have been working great!  Recently, however, it has dropped a couple of calls in mid-conversation.   What’s up?

The Solution: If the HL10 lifter is actually hanging up the phone mid conversation there are several possible quick fixes that may solve your problem.   First, check the small height adjustment button on the back of your Plantronics HL10 lifter.  You have a choice of low, medium or high settings.   We suggest you set it on the medium  (middle) setting because it works best for the majority of phones.    With some phones if you set the HL10 on the low setting the handset is simply too heavy, so it slowly hangs up on you.

If that adjustment doesn’t solve your problem, lift your handset off the phone and manually pull the arm on your HL10 lifter up as high as it will go; then slowly push it back down.  If the problem persists, your next option is to do a reset on your headset.  You will find detailed instructions with pictures located on our Plantronics CS55 product page, under FAQ’s.  Once you have completed the reset, your headset and lifter should be ready to go!

Although the Plantronics CT12 and Plantronics CT14 systems look alike, they do use different headsets.  The CT12 headset (part # 64378-01) has a red light on the end of the microphone that illuminates when in use (on a call), the remote unit sends an “electronic pulse” to the headset which makes this happen.  Other headsets, including the CT14 headset (part # 81083-01), will “technically” work with the CT12 system, but we only recommend using the actual CT12 replacement headset.  When using any other headset besides the original on a CT12 (including the CT14), you will more than likely hear the electronic pulsating sound fading in and out, and you could possibly also have a buzzing issue as well.

Problem: My Plantronics 10U100 wireless headset stopped working, what can I replace it with?

Solution: The Plantronics CT14.  The 10U100 was typically used with the Avaya Partner phones, such as the 18D and 34D models.  The CT14 would be the closest model replacement for the older discontinued 10U100 system.  The CT14 has a slimmer and more modern design with longer range (300ft) and talktime (10hrs), while still having the basic features of being able to answer, dial and transfer calls when used with the Avaya Partner 18D & 34D phones.  And because the CT14 plugs into the “AUX” (auxillary) jack on the bottom of the phone, the HL10 Handset Lifter is not required for remote one-touch answering.
