We all know Leitner Wireless Headsets have a switch on the bottom of the base that says RHL/DHSG right? Well, if you have one, give it a check! But what does it mean?

DHSG is a German acronym (Drahtlose Hör-Sprechgarnitur). All it means is "Wireless headset". In practice, it generally refers to electronic hookswitch (EHS) cables, which can give you the ability to answer calls while away from the desk with specific phones.

What happens in DHSG?
Most of the time, we want to set this to RHL (there are only a few rare hookswitch exceptions)... well, here’s some other stuff that could happen if you have the button set to DHSG instead of RHL.
1. DHSG disables the handset port completely. If there is no sound in the handset port, check that we are on RHL. If moving it back to RHL doesn’t seem to work, try putting the button back on DHSG and then rapidly clicking it back to RHL, as sometimes the switch may not be fully on one or the other.
2. The clicking sound the base makes when the headset turns on will also be disabled when on DHSG! If you’re not hearing the clicks, check that switch. If moving it back to RHL doesn’t seem to work, try putting the button back on DHSG and then rapidly clicking it back to RHL, as sometimes the switch may not be fully on one or the other.
Note: We only have 4 EHS cords that require the base to be in DHSG. So if you don't have these cords, stick with the RHL setting.
