Do you use a NEC DT330, DT730, DT750 office phone and a Plantronics wireless headset? If so, you’re in luck, there is now a EHS (electronic hook switch) available for your phone. Instead of using a HL10 handset lifter, you now can use the Plantronics APN-91 EHS Cable. It works much faster connecting your calls, and it doesn’t have any mechanical moving parts like the Plantronics HL10 lifter.
the new APN-91 EHS only works with the newer Plantronics CS500, and W700 series wireless headsets. Unfortunately, there are no equivalent for the older CS models like the CS50, CS55, CS70, CS351, CS361. You will still have to use the HL10 lifter if you own one of these models.
