Using the HSL 10

The handset lifter, HSL 10, is our mechanical call control solution for deskphones where no EHS function is possible. This device will listen for incoming calls, send an alert signal to your headset when one is detected, and allow you to accept the call remotely by physically lifting the handset. 




How to connect and affix your HSL 10

The HSL needs only to be connected via the supplied cable to our base station. Connect one end of the supplied cable to the port on the HSL 10, and the other end to the purple 'ACC' port on your base station. There is a microphone attached to the back of the unit.

If there is a speaker underneath the handset (as is common on many deskphones), then there is no need to adjust the microphone. If the speaker of your deskphone is located somewhere else, then please position the microphone near it and affix it in place using the provided double-sided adhesive strip. 

The HSL itself should be positioned between the deskphone and the handset in such a way that the unit can lift up the handset to connect the call, but without the handset falling out of the cradle. You can check this by pressing the multifunction on the headset, which should cause the HSL to raise. It may be necessary to adjust the lifting height to find the correct position (see below).

Please do not affix the unit to your deskphone until after you have ascertained the correct position for it, as the adhesive tape may only be used once. 

How to adjust the lifting height of the HSL 10

To adjust the lifting height, press and hold both the P1 and P2 buttons on your HSL. Release them once the LED begins to alternately flash blue and red. 

You can now use the P1 and P2 buttons to respectively increase or decrease the lifting height until you find the correct setting. You should be able to lift the handset high enough to initiate a dial tone, but not so high the handset will slip out of the cradle. 

Once you have found the correct height, save your settings by pressing and holding P1 and P2 again until the HSL lowers itself.

How to train your HSL 10 to recognise your deskphone's ringtone

The HSL can be trained to recognise two ringtones. This will ensure that the HSL does not incorrectly identify background noise as a ringtone and alert you without a call actually being present. 

To train your unit to your ringtone, first press and hold the P1 button until the LED begins to flash blue. Once flashing, play the ringtone of your deskphone. You may be able to do this via the deskphone's menu, or it may be necessary to call yourself, depending on your model of phone. Once the ringtone has been successfully learnt, the LED will flash red twice. 

Now complete the steps again, but this time pressing and holding the P2 button until the LED begins to flash red. If your phone generates two different ringtones, for example, one for internal and one for external calls, then please use P2 to train the HSL for this second ringtone. If not, simply train it in the same fashion as for the first setting. Once the second ringtone is learnt, the LED will flash blue twice.
