Siemens 1190 User Manual

It is an accessory that can be installed on terminals to 

replace the use of the handset and provide the user 

with more comfort and with hand-free operation.

Models with electronic hook control (such as Siemens 

Elipse 1.8 EHS and GN Netcom 9120) for answering 

calls using a headset must use a 16 optiPoint Acoustic 

Adapter, regardless of the optiPoint model used. opti-

Point Advanced features include a built-in headset inter-

face. However, an optiPoint Acoustic Adapter is re-

quired for connecting the headset. When an optiPoint 

key is configured for using a headset (optional setting, 

the system behaves as if a headset is connected. 

Therefore, it is recommended that when you discon-

nect the headset you change the key configuration ac-

cordingly.

If you want to use a Siemens Elipse 1.8 EHS or GN Net-

com 9120 set without the electronic hook control 

switch, you must use an optiPoint Acoustic Adapter for 

optiPoint Entry, Basic and Standard models. For the op-

tiPoint Advanced, an optiPoint Acoustic Adapter is op-

tional. The headset can be connected to the built-in in-

terface on the telephone’s rear panel using a RJ45 

connector. The Headset feature key must be pro-

grammed to answer calls.

Headset models without an electronic hook key (e.g., 

Plantronics) can be connected directly to the handset’s 

interface on a optiPoint (Entry, Basic or Standard) tele-

phone, as well as through an optiPoint Acoustic Adapter 

or the built-in interface (optiPoint Advanced only). How-

ever, in order to be detected by the system, a Headset 

key must be programmed, regardless of the configura-

tion used. 

[1] For installing and configuring a headset follow the instructions pro-

vided in its accompanying manual. For a view of the optiPoint rear 
panel see ”Back panel: optiPoint 500” 

The MUTE option must be enabled/disabled on the same equip-
ment.
If you have any questions, please contact your system’s Support 
Technician.

When an optiPoint key is configured for using a 

headset (optional setting, the system behaves as 

if a headset is connected. Therefore, when you 

disconnect the headset you must change the 

key configuration accordingly.
