Grandstream Networks GXW400x Manuel D’Utilisation

 

Polarity Reversal  Default is No.  If set to “Yes”, polarity will be reversed upon call establishment and 

termination. 

 

Handset volume adjustment.  RX is for receiving volume, TX is for transmission 
volume.  Default values are 0dB for both parameters.  Loudest volume:  +6dB 
Lowest volume:  -6dB. 

Configure ring or tone frequencies according to preference.  By default tones are 
set to North American frequencies.  Frequencies should be configured with known 
values to avoid uncomfortable high pitch sounds.  

 

Once a change is made, press the “Update” button in the Configuration Menu. The GXW–400x will 
display the following screen to confirm that the changes have been saved.  Reboot or power cycle the 
GXW–400x after all the changes are made so that those changes can take effect.
