Editing the file /etc/profile. How to???

[Kirith]

We in Russia are trying to remove the icons (and functions) of the sound in i62ML. By editing the file -/etc/profile
The differences in this file in different firmware versions is:
Rus:

export SUSPEND_INTERVAL = 300000
export SHUTDOWN_INTERVAL = 1200000

export DISABLE_TTS = 1
export DISABLE_DICT = 1
export DISABLE_VOLUME_ICON = 1
# export DISABLE_NEVER_STANDBY_SHUTDOWN = 1
export CUSTOM_PM = 2

GERMAN:

export SUSPEND_INTERVAL = 600000
export SHUTDOWN_INTERVAL = 900000

export DISABLE_NEVER_STANDBY_SHUTDOWN = 0

export CR3_TOUCH_CONTROL_NAVIGATION = 1
export DISABLE_CHANGE_TO_SCROLL_MODE = 1
# For default language settings
export DEFAULT_LOCALE = en_US.UTF-8

export ABSOLUTE_DOWNLOAD_PATH = / media / flash /
export DOWNLOAD_PATH_CONTEXT = "/ media / flash / DRM Contents /"

[-F / root / Settings / default_locale] && source / root / Settings / default_locale

What is:

 export CUSTOM_PM = 2

I do not know ... But it hardly affects the sound ...
Who will help the council?

Мы в России пытаемся убрать иконки (и функции) звука. Редактируем файл -/etc/profile
Отличия в этом файле в разных прошивках:
РУС:

export SUSPEND_INTERVAL=300000
export SHUTDOWN_INTERVAL=1200000

export DISABLE_TTS=1
export DISABLE_DICT=1
export DISABLE_VOLUME_ICON=1
#export DISABLE_NEVER_STANDBY_SHUTDOWN=1
export CUSTOM_PM=2

# for glow right (front light)
export GLOW_LIGHT=1

НЕМЕЦКИЙ:

export SUSPEND_INTERVAL=600000
export SHUTDOWN_INTERVAL=900000

export DISABLE_NEVER_STANDBY_SHUTDOWN=0

export CR3_TOUCH_CONTROL_NAVIGATION=1
export DISABLE_CHANGE_TO_SCROLL_MODE=1
# for default language settings
export DEFAULT_LOCALE=en_US.UTF-8

export ABSOLUTE_DOWNLOAD_PATH=/media/flash/
export DOWNLOAD_PATH_CONTEXT="/media/flash/DRM Contents/"

[ -f /root/Settings/default_locale ] && source /root/Settings/default_locale

Что такое:

export CUSTOM_PM=2

я не знаю... Но вряд-ли это влияет на звук...
Кто поможет советом?
