set to L
OGARITHMIC
(dB) scale, the volume values are scaled logarithmically.
The volume meters of digital audio devices usually are scaled this way. On
the other hand, if you are interested in the power level that is applied to
your headphones you should choose L
INEAR
display. This setting cannot
be displayed in units like volts or watts because such units depend on your
headphones.
Minimum and maximum range:
These two options define the full value range
that the peak meter displays. Recommended values for the L
OGARITHMIC
(dB) setting are -40 dB for minimum and 0 dB for maximum. Recommended
values for L
INEAR
display are 0 and 100%. Note that -40 dB is approximately
1% in linear value, but if you change the minimum setting in linear mode
slightly and then change to the dB scale, there will be a large change. You
can use these values for ‘zooming’ into the peak meter.
Default Codepage:
A codepage describes the way extended characters that are not
available within the ASCII character set are encoded. ID3v1 tags do not have
a codepage encoding contained so Rockbox needs to know what encoding has
been used when generating these tags. This should be “ISO-8859-1” but to sup-
port languages outside Western Europe most applications use the setting of your
operating system instead. If your operating system uses a different codepage and
you are getting garbled extended characters you should adjust this settings. In
most cases sticking to “ISO-8859-1” would be sufficient.

playback where it was when the player was shut off if there is a playlist to resume and
will then end up in the WPS. Selecting P

will make Rockbox start in
the screen it was when the player was shut off.
7.6.2 Battery
Options relating to the battery in the player.
Battery Capacity:
This setting can be used to tell Rockbox what capacity (in mAh) the
battery being used has. The default is 1300mAh, which is the capacity value for
the standard battery shipped with the player. Rockbox uses this value to estimate
remaining battery life for the info screen and WPS. Changing this setting has no
effect whatsoever on actual battery life. This setting only affects the accuracy of
the battery life estimation as shown on screen.
Charge During USB Connection:
This option lets you control whether the player
should charge during the USB connection and hence draw the full 500mA. Turn-
