Prerequisite:

Connection:

Aastra DHSG cable:

Insert the split end of the Aastra DHSG cable into your phone as follows.

 

1. Insert the RJ10 plug (marked green) into the “headset” socket and the RJ45 plug (marked yellow) into the socket for the expansion module. [Grün = green][Gelb = yellow]
2. Insert the 1-sided end of the Aastra DHSG cable marked in blue into the Aastra RJ45-RJ45 adapter.
3. Now insert the 1-sided end of the Jabra Link 14201-10 cable marked “blue” into the free socket of the RJ45 adapter.

 4. Insert the RJ10 plug into the socket with the complete “phone” symbol and the RJ45 plug into the socket marked with "AUX" on the GN9350 base.

 

EHS setup:

The Jabra GN912x must support and be set up to DHSG EHS.


You can check or set it up as follows:

1. Place the headset on the base.
2. Then press the PLUS and MINUS buttons simultaneously for 6 seconds until the online display on the headset starts to flash.
3. The base will now display to you the EHS currently installed. The online light indicates "MSH", the pulsating light indicates "RHL", the MUTE light "DHSG" and the battery display "AEI".
   
   
4. With the PLUS or MINUS buttons, you can now switch between the different EHS types. To confirm the EHS has successfully installed, the phone automatically switches back to charge mode after approx. 10 seconds.

Microphone level setup:

1. Please call someone with the headset.
2. On the headset, you must now simultaneously press the PLUS and MINUS buttons which immediately produces a signal tone.
