   3 \subsection{Start Screen}
   4     Set the screen that Rockbox will start in. Selecting
   5     \setting{Resume Playback} will resume playback where it was when the \dap{}
   6     was shut off if there is a playlist to resume and will then end up in the
   7     WPS. Selecting \setting{Previous Screen} will make Rockbox start in the
   8     screen it was when the \dap{} was shut off.

  10 \subsection{Battery}
  11     Options relating to the \opt{archos}{batteries}\nopt{archos}{battery}%
  12     in the \dap.
  13   \begin{description}
  14     \item [Battery Capacity: ]This setting can be used to tell Rockbox what
  15       capacity (in mAh) of battery is being used inside it. The default is
  16       \opt{player,recorder}{1500mAh}%
  17       \opt{recorderv2fm}{2200mAh}%
  18       \opt{ondiosp,ondiofm}{1000mAh}%
  19       \opt{h1xx,h300}{1300mAh}%
  20       \opt{ipodmini}{400mAh (1G) or 630mAh (2G)}%
  21       \opt{ipodcolor}{700mAh}%
  22       \opt{ipodnano,ipodvideo,ipod4g,ipod3g}{\fixme{unknown}}%
  23       \opt{x5}{950mAh}%
  24       , which is the capacity value for the standard batteries shipped with the
  25       \dap. Rockbox uses this value to estimate remaining battery life for the
  26       statusbar and WPS. Changing this setting has no effect what-so-ever on
  27       actual battery life. This setting only affects the accuracy of the
  28       battery life estimation as shown on screen.
  29
  30       \opt{ipod}{This value is fairly meaningless in the \playerman{} family at
  31         present, and work is on-going into finding a better way to determine
  32         battery life.}
  33
  34     \opt{ondiosp,ondiofm}{
  35     \item [Battery Type: ]This setting tells Rockbox which type of battery
  36       that is currently used in the \dap{}. Select \setting{Alkaline} or
  37       \setting{NiMH} with \ButtonUp/\ButtonDown.

  42 \subsection{Disk}
  43     Options relating to the hard disk.
  44
  45   \begin{description}
  46     \item [Disk Spindown: ]Rockbox has a timer that makes it spin down the
  47       hard disk after it is idle for a certain amount of time. This setting
  48       controls the amount of time between the last user activity and the time
  49       that the disk spins down. This idle time is only affected by user
  50       activity, like navigating through the \setting{File Browser}. When the
  51       hard disk spins up to fill the audio buffer, it automatically spins down
  52       afterwards.
  53
  54     \opt{SWCODEC}{
  55     \item [Directory Cache: ]Rockbox has the ability to cache the contents of
  56       your drive in RAM. The \setting{Directory Cache} takes a small amount of
  57       memory away from Rockbox that would otherwise be used to buffer music,
  58       but it speeds up navigation in the \setting{File Browser} by eliminating
  59       the slight pause between the time a navigation button is pressed and the
  60       time Rockbox responds. Turning this setting \setting{On} activates the
  61       directory cache, and turning it \setting{Off} deactivates the directory
  62       cache.
  63       \note{The first time you set the directory cache to \setting{On},
  64       Rockbox will request a reboot of the \dap{} and upon restarting take a few
  65       minutes to scan the drive. Thereafter, the directory cache will work in the
  66       background.}

  73   Time related menu options.

  75       \item [Set Time/Date: ]Set current time and date.
  76       \item [Time Format: ] Choose 12 or 24 Hour clock.

  80 \subsection{Idle Poweroff}
  81 Rockbox can be configured to turn off power after the unit has been idle for a
  82 defined number of minutes. The \dap{} is idle when playback is stopped or
  83 paused. It is not idle while the USB or charger is connected, or while
  84 recording. Settings are either \setting{Off} or \setting{1} to \setting{10}
  85 minutes in 1 minute steps. Then \setting{15,30,45} and \setting{60} minutes are
  86 available.
  87
  88 \opt{HAVE_RTC_ALARM}{
  89 \subsection{Wake Up alarm}
  90     This option turns the \dap{} off and then starts it up again at the
  91     specified time. This is most useful when combined with
  92     \setting{Start Screen} set to \setting{Resume Playback}, so
  93     that the \dap{} wakes up and immediately starts playing music. Use
  94     \ActionSettingInc{} and \ActionSettingDec to adjust the minutes setting,
  95     \ButtonLeft{} and \ButtonRight{} to adjust the HOURS.
  96     \ButtonPlay{} confirms the alarm and shuts your \dap{} down, and
  97     \opt{RECORDER_PAD}{\ButtonOff}\opt{IPOD_4G_PAD,IPOD_3G_PAD}{\ButtonMenu}
  98     cancels setting an alarm. If the \dap{} is turned on again before the alarm
  99     occurs, the alarm will be cancelled. Using this option disables the
 100     \setting{Sleep Timer}.

 102
 103 \subsection{Limits}
 104 This sub menu relates to limits in the Rockbox operating system.
 105   \begin{description}
 106     \item [Max files in dir browser: ]This setting controls the limit on
 107     the number of files that you can put in any particular directory in the
 108     \setting{File Browser}. You can configure the size to be between 50 and
 109     10,000 files in steps of 50. The default is 400. Higher values will shorten
 110     the music buffer, so you should increase this setting \emph{only} if you have
 111     directories with a large number of files.
 112
 113     \item [Max playlist size: ]This setting controls the maximum size of
 114     a playlist. The playlist size can be between 1,000 and 20,000 files,
 115     in steps of 1,000 (default is 10,000). Higher values will shorten the
 116     music buffer, so you should increase this setting \emph{only} if you
 117     have very large playlists.

 121 \subsection{Car Adapter Mode}
 122       This option turns \setting{On} and \setting{Off} the car ignition
 123       auto stop function.
 124   \begin{description}
 125   \item [Car Adapter Mode: ]When using the \dap{} in a car,
 126   \setting{Car Adapter Mode} automatically stops playback on the \dap{} when
 127   power (i.e. from cigarette lighter power adapter) to the external DC in jack
 128   is turned off. If the \setting{Car Adapter Mode} is set to \setting{On},
 129   Rockbox will pause playback when the external power off condition is
 130   detected. Rockbox will then shutdown the \dap{} after the length of time set
 131   in the \setting{Idle Poweroff} setting (see above).
 132   If power to the DC in jack is turned back on before the \emph{Idle Poweroff}
 133   function has shut the \dap{} off, playback will be resumed 5 seconds after
 134   the power is applied. This delay is to allow for the time while the car
 135   engine is being started.
 136   \end{description}
 137
 138   Once the \dap{} is shut off either manually, or automatically with the
 139   \setting{Idle Poweroff} function, it must be powered up manually to resume
 140   playback.

 144   \subsection{Line In} This option activates the line in port on \dap, which is
 145     off by default. This is useful for such applications as:
 146     \begin{itemize}
 147     \item Game boy $\rightarrow$ \dap $\rightarrow$ human
 148     \item laptop $\rightarrow$ \dap $\rightarrow$ human
