Close the DC "Click" sound for K700i

Method to close DC sound (updated):
I am using English interface

1. Select a profile that seldom use,( I choose "office")
2. edit profile
- Volume = 0
- Silent mode = on
- Increasing ring = off
- Key sound = silent
- Change the profile name (up to u)
3. save
4. when u close DC sound, select this profile

I try this again. It works.

Pls. leave comment if success.
