Throughout this manual, the buttons on the \dap{} are labelled according to the
picture above. When a table of button actions says ``Long'' before the button it
means that you should make a long press on that button, in other words, press it
for approximately 1 second. In detail the buttons are described in the following
paragraph.

  \opt{h1xx}{ 
  If you lay the \dap{} on the table with the joystick pointing 
  towards you, and the curved sides at the top, you will find the following 
  if you start from the top-right corner and follow the side of the \dap{} in a
  clockwise direction:
  On the right side the buttons \ButtonOn{}, \ButtonOff{}, \ButtonMode{} and
  the \ButtonHold{} switch. Next comes on the bottom the USB port,
  a small hole for resetting the \dap{}, charger plug. On the left side located
  is the button \ButtonRec{}. At least the top has headphone mini-jack plug,
  remote port, optical/line in and optical/line out.
  The joystick in the middle of the \dap{} is 
  used to navigate menus by pressing it up, down, left and right. Pressing the 
  joystick down is labelled \ButtonSelect{} throughout this manual. Its
  directions are labelled \ButtonRight{}, \ButtonDown{}, \ButtonLeft{} and
  \ButtonUp{}.
  
  The internal microphone is located on the left hand side of the nit towards the
  top, and there is a small reset hole on the bottom of the unit between the 
  power and USB sockets.  To perform a hard reset, insert a paperclip into this
  hole.}
  % 
  \opt{h300}{
  Hold or lay the \dap{} so that the side with the button pad and
  LCD is facing towards you.  The buttons on the button pad are as follows:  top 
  left corner: \ButtonOn{}, bottom left corner: \ButtonOff{}, top right corner: 
  \ButtonRec, bottom right corner: \ButtonMode{}.  In the center of the button pad 
  is a button labelled \ButtonSelect{}.  Surrounding the \ButtonSelect{} button are
  four directional buttons used to navigate up, down, left and right.
  
  On the top panel of the \dap{}, from left to right, you can find the 
  following: headphone mini jack plug, remote port, Line-in, Line-out. 
  
  On the bottom panel of the \dap{}, from left to right, you can find the 
  following:  power jack and two USB ports.  The USB port on the right is used 
  to connect your \dap{} to your computer.  The USB port on the left is not 
  used in Rockbox.

  \opt{ipod4g,ipod3g,ipodcolor,ipodvideo,ipodmini}
  { 
  The main controls on the \dap{} are a slightly indented scroll wheel 
  with a flat round button in the center. Hold the \dap{} with these controls 
  facing you. 

  The top of the player will have the following, from left to 
  right:
  \opt{ipod4g, ipod3g ,ipodcolor}{remote connector, headphone jack, \ButtonHold{} 
    switch.}
  \opt{ipodvideo}{\ButtonHold{} switch, headphone jack.}
  \opt{ipodmini}{\ButtonHold{} switch, remote connector, headphone jack.}	

  The dock connector that is used to connect your \dap{} to your computer is on 
  the bottom panel of the \dap{}.

  The button in the middle of the wheel is called \ButtonSelect{}. You can
  operate the wheel by pressing the top, bottom, left or right sections,
  or by sliding your finger around it.  The top is \ButtonMenu{}, the bottom is
  \ButtonPlay{}, the left is \ButtonLeft{}, and the right is \ButtonRight{}.
  When the manual says to \ButtonScrollFwd{}, it means to slide your finger
  clockwise around the wheel. \ButtonScrollBack{} means to slide your finger
  counterclockwise. Note that the wheel is sensitive, so you will need to move
  slowly at first and get a feel for how it works.
  
  Note that when the \ButtonHold{} switch is pushed toward the center of the \dap{}, 
  hold is on, and none of the other controls do anything.  Be sure
  \ButtonHold{} is off before trying to use your player.

    Rockbox has a dual-boot feature. To boot into the original firmware, shut
    down the device as described above. Turn on the \ButtonHold{} switch
    immediately after turning the player on. Once Rockbox displays the
    message ``Loading original firmware ...'' you may turn the \ButtonHold{}
    switch off. Rockbox will boot into the original firmware.
    
    \note{The described method of dual-booting works with Rockbox bootloader
    version 2, which was released 16 December 2006. If you have the older
    bootloader, boot the original firmware by pressing \ButtonMenu{}
    immediately after turning on your Ipod.  Do not release the
    \ButtonMenu{} button until you see the ``Loading original firmware...''
    message on the screen.}
    
    Regardless of which method you use to boot to the original firmware, you can
    return to Rockbox by pressing and holding \ButtonMenu{} and \ButtonSelect{}
    simultaneously until the player hard resets.

  }

\subsection{The first contact}

After you have first started the \dap{} you'll be presented by the
\setting{Main Menu}. From this menu you can reach every function of Rockbox,
for more information (see \reference{ref:main_menu}). To browse the files
on you \dap{} select \setting{Files} (see \reference{ref:file_browser}), and to
browse in a view that is based on the meta-data\footnote{ID3 Tags, Vorbis
comments, etc.} of your audio files, select \setting{Database} (see
\reference{ref:database}).

\subsection{Basic controls}
When browsing files and moving through menus you usually get a list view
presented. The navigation in these lists are usually the same and should be
pretty intuitive.
In the tree view use \ActionStdNext{} and \ActionStdPrev{} to move around
the selection. Use \ActionStdOk{} to select an item. When browsing the file
system selecting an audio file plays it. The view switches to the ``While
playing screen'', usually abbreviated as ``WPS'' (see \reference{ref:WPS}. The
dynamic playlist gets replaced with the contents of the current directory. This
way you can easily treat directories as playlists. The created dynamic playlist can
be extended or modified while playing. This is also known as
``on-the-fly playlist''.
To go back to the \setting{File Browser} stop the playback with the
\ActionWpsStop{} button or return to the file browser while keeping playback
running using \ActionWpsBrowse{}.
In list views you can go back one step with \ActionTreeParentDirectory.

\subsection{Basic concepts}
\subsubsection{Playlists}
Rockbox is playlist oriented. This means that every time you play an audio file,
a so-called ``dynamic playlist'' is generated, unless you play a saved
playlist. You can modify the dynamic playlist while playing and also save
it to a file. If you do not want to use playlists you can simply play your
files directory based.
Playlists are covered in detail in \reference{ref:working_with_playlists}.

\subsubsection{Menu}
From the menu you can customise Rockbox. Rockbox itself is very customisable.
Also there are some special menus for quick access to frequently used
functions.

\subsubsection{Context Menu}
Some views, especially the file browser and the WPS have a context menu.
From the file browser this can be accessed with \ActionStdContext{}.
The contents of the context menu vary, depending on the situation it gets
called. The context menu itself presents you with some operations you can
perform with the currently highlighted file. In the file browser this is
the file (or directory) that is highlighted by the cursor. From the WPS this is
the currently playing file. Also there are some actions that do not apply
to the current file but refer to the screen from which the context menu
gets called. One example is the playback menu, which can be called using
the context menu from within the WPS.

\section{Customising Rockbox}
Rockbox' User Interface can be customised using ``Themes''. Themes usually
only affect the visual appearance, but an advanced user can create a theme
that also changes various other settings like file view, LCD settings and
all other settings that can be modified using \fname{.cfg} files. This topic
is discussed in more detail in \reference{ref:manage_settings}.
The Rockbox distribution comes with some themes that should look nice on
your \dap{}. \note{Some of the themes shipped with Rockbox need additional
fonts from the fonts package, so make sure you installed them.
Also, if you downloaded additional themes from the Internet make sure you
have the needed fonts installed as otherwise the theme may get displayed
garbled.}
