Overview

CM-QS600 supported features are operated using normal Android controls.
This page contains information about features and services, which are less straight-forward to operate, or are less widely known. Enabling platform features page may be considered complimentary developer insight to this page.

Operating instructions

Automatic suspend when inactive

By default, CM-QS600 is configured to stay awake while connected to the power supply.
In order to change this behaviour, proceed to Settings->Developer options, uncheck Stay awake ... while charging option to enable the device suspend state.

Admolition note.png If Developer options item is hidden, re-introduce it by proceeding to Settings->About tablet and clicking on Build number 7 times consequently.

Networking

Normal Android behaviour is to prioritize network interfaces (in descend order):

  • Ethernet
  • WiFi
  • 3G

Whenever higher-priority network interface is available, the lower-priority interfaces will be torn down.

Cellular Modem

CM-QS600 Android supports Telit HE910-XX 3G modem (supplied optionally) out of the box.
In case Telit HE910-XX 3G modem is installed, it will be detected and started automatically, with no additional actions required.

Audio sink selection

CM-QS600 may use either HDMI or analog audio output device. Audio sink selection should be done with a designated application, e.g. SoundAbout, available via Google Play Store.

audio device sink name
HDMI Aux Digital (HDMI)
analog Wired Headphones


Admolition note.png If after making the selection with SoundAbout, the sound routing does not change, restart the SoundAbout application.

LVDS display

CM-QS600 Android kernel supports Chi Mei (N116B6-L02) LVDS display (not supplied).
In order to send video output to the LVDS display, add the following parameter to the kernel command line:

prim_display=lvds_chimei_wxga
