Scale
ScaleScale
Scale: Select whether the peak meter displays linear or logarithmic values. In
“dB” (decibel) scale the volume values are scaled logarithmically. This very
similar to the perception of loudness. The volume meters of digital audio
devices usually are scaled this way. If you are interested in the power level
that is applied to your headphones you should choose “linear” display.
Unfortunately this value doesn't have real units like volts or watts since that
depends on the phones. So they can only be displayed as percentage
values.
Minimum and maximum range
Minimum and maximum rangeMinimum and maximum range
Minimum and maximum range: These two options define the full value
range that the peak meter displays. Recommended values for dbFs are -40
for min. and 0 for maximum. For linear display, use 0 and 100%. Note that -40
dbFs is approximately 1% in linear value, but if you change the minimum
setting in linear mode slightly and then change to dbFs there will be a large
change. You can use these values for 'zooming' into the peak meter.

Battery Capacity

Battery Capacity can be used to tell the Jukebox what capacity (in mAh) of
battery is being used inside it. The default is 1500mAh for NiMH battery based
units, and 2300mAh for LiOn battery based units, which is the capacity value
for the standard batteries shipped with these units. This value is used for
calculating remaining battery life.

Set this to ON if you intend to keep your charger connected for a long period
of time. It lets the batteries go down to 10% before starting to charge again.
Setting this to OFF will cause the charging to restart on 95%.

The Jukebox cannot be turned off while the charger is connected. Therefore,
trickle charge is needed to keep the batteries full after charging has
completed. For more in depth information about charging see Battery FAQ in

: Rockbox has a timer that makes it spin down the hard disk
after being idle for a certain time. You can modify this timeout here. This idle
time is only affected by user activity, like navigating through file browser.
When the hard disk spins up to fill mp3 buffer, it automatically spins down
afterwards.
