How to program memory keys for configuration

[Yealink_Peter]

Hi,

You can use the "XML Browser" feature.
1.Define 4 xml files and each for backlight always on, backlight always off, ringer volume to 15 and volume to 0
2.Create a http or tftp server to store the 4 xml files
3.Configure 4 DSSKeys as "XML Browser" type and fill the corresponding URL(the xml file URL stored in server) in each volume field. Show as image below:
   
For example:
parameters for backlight always on:
phone_setting.backlight_time = 0
parameters for backlight always off:
phone_setting.backlight_time = 1
parameters for ringer volume to 15:
voice.ring_vol = 15
parameters for ringer volume to 0:
voice.ring_vol = 0
I have also uploaded the xml files as attachment for your reference.

Thank you.
Regars,
Peter
