If you use a Plantronics HL10 handset lifter, you may find that at one point in time, you’ll not get remote ring detection. That is, you’ll be away from your desk and not get an audible alert notifying you of an incoming call. This can be all of a sudden or it might be upon the initial installation.  In either case, one of the major benefits of using a lifter is to know when you’re getting a call when away from your desk and then to be able to answer it. That convenience and efficiency is seriously hampered when this feature isn’t working correctly.

This blog will cover a few things that you can try in order to get the Plantronics HL10 handset lifter functioning properly.  These same suggestions will work on other brands of lifters as well, such as Jabra, Discover and Sennheiser.

The first thing to check is

telephone keypad

The Plantronics HL10 handset lifter has a very small sensor located on the bottom. This sensor needs to be positioned so that it’s above the telephone speaker. When sound is emitted from the telephone speaker, such as an incoming call, the sound waves penetrate the sensor, which in turn triggers the beep tone/audible alert you have an incoming call. An image of this sensor and where it’s located on the HL10 Lifter is shown below.

If your phone volume is set too low, the velocity of the sound waves generally aren’t sufficient to trigger the beep tone in the headset. The result? You get an incoming call when away from your desk, but you’re not aware of it and the call goes unanswered or heads off to your voice mail.

Try this to help resolve this problem.

  • Adjust your TELEPHONE speaker volume so that it’s about halfway
  • Have someone call you and let the phone ring a few times before answering
  • Do you hear the beep tone in the headset earpiece? If not,
  • Turn up the volume a little more on your phone and continue to do this until you hear the beep tone in your headset.
  • Problem solved!

lifter above speaker

If you don’t get the lifter aligned correctly resulting in the sensor not being positioned above the speaker, then the sensor can’t do its job to provide the incoming call alert. Double check to be sure that everything is aligned correctly. If not, remove the lifter, realign it and  then re-attach it.  You might need some replacement double-sided tape because when you remove the lifter a time or two, the double sided tape tends to lose its stickiness which prevents the lifter from adhering to the phone securely.

where's the speaker located

There are some phones that don’t have the speaker in the traditional location (under the handset). One example is shown below.  This is a phone originally produced by Nortel, then Aastra and more recently, Mitel.

If your phone has a speaker in a location other than under the handset, you’ll need an accessory called a “remote ring detector” cord. See item image below.

In the phone example above, the circular end of the remote ring detector sticks to the surface of the speaker grill on the phone. This positions it in the right spot to receive sound waves, when the phone is ringing, which in turn triggers an audible ring tone. The opposite side of this cord (2.5mm pin connector), plugs in to the back of the Plantronics HL10 as per the image below.

Once you have the remote ring detector plugged in and situated on your phone speaker grill, have someone call you, but make sure that the phone volume is set at least half way. Let the phone ring a few times before attempting to answer it.  You want to make sure to give the lifter and remote detector sufficient time to sense the incoming call. If you don’t get an audible ring tone, turn up the volume a bit more and repeat the process.

HL10 firmly plugged in

It’s not uncommon for the HL10 lifter to have the appearance of being plugged in fully, but in reality, it’s not plug in all the way. This normally causes the lifter to not work at all. Odd as it may seem, a perfectly functioning lifter can all of a sudden, cease working for this reason and of course, no ring detection. The Plantronics HL10 is the only lifter in the industry that uses a 3.5mm pin connector.  Other brands such as the Discover, Jabra and Sennheiser all use an RJ45 style connector that doesn’t have this issue.

The other thing you might check is your headset battery.

Make sure your battery is charged

If you don’t have sufficient charge in the headset battery the lifter won’t work correctly. You can experience no remote ring detection and you might also experience no lifter functionality at all.  So double-check to make sure you have enough charge in your headset battery. If the battery is over two years old, consider replacing it.

try a different ring tone

Most phones will give you choices of different ring tones. If you’re having trouble getting ring detection (beep tone in your headset earpiece), try selecting different ring tones until you find one that works.

  • Select a different ring tone on your phone
  • Have someone call you and let it ring a few times to see if you hear a beep tone in your headset earpiece.  If not, try another ring tone and repeat.
  • Remember to have the phone volume AT LEAST half way up in volume as you do this test.

Some ring tones have a cadence that isn’t recognized by the sensor no matter how high you turn up the phone volume. In these cases, the problem isn’t stemming from insufficient volume but an unrecognized cadence instead.

Hopefully these tips can help you to troubleshoot your Plantronics HL10 handset lifter. As mentioned earlier, these same tips can work for other brands of lifters as well.
