\subsection{VU meter} \screenshot{plugins/images/ss-vumeter}{VU-Meter}{} This is a VU meter, which displays the volume of the left and right audio channels. There are 3 types of meter selectable. The analogue meter is a classic needle style. The digital meter is modelled after LED volume displays, and the mini{}-meter option allows for the display of small meters in addition to the main display (as above). From the settings menu the decay time for the meter (its memory), the meter type and the meter scale can be changed. \begin{table} \begin{btnmap}{}{} \opt{RECORDER_PAD,ONDIO_PAD,IRIVER_H100_PAD,IRIVER_H300_PAD}{\ButtonOff} \opt{IPOD_4G_PAD,IPOD_3G_PAD}{\ButtonMenu} \opt{IAUDIO_X5_PAD,IRIVER_H10_PAD,SANSA_E200_PAD}{\ButtonPower} & Save settings and quit\\ \opt{RECORDER_PAD,IRIVER_H100_PAD,IRIVER_H300_PAD}{\ButtonOn} \opt{ONDIO_PAD}{\ButtonMenu} \opt{IPOD_4G_PAD,IPOD_3G_PAD,IAUDIO_X5_PAD,IRIVER_H10_PAD}{\ButtonPlay} \opt{SANSA_E200_PAD}{\ButtonRec} & Help\\ \opt{RECORDER_PAD}{\ButtonFOne} \opt{ONDIO_PAD}{Hold \ButtonMenu} \opt{IRIVER_H100_PAD,IRIVER_H300_PAD,IPOD_4G_PAD,IPOD_3G_PAD,IAUDIO_X5_PAD,SANSA_E200_PAD}{\ButtonSelect} \opt{IRIVER_H10_PAD}{\ButtonRew} & Settings\\ \opt{RECORDER_PAD,ONDIO_PAD,IRIVER_H100_PAD,IRIVER_H300_PAD,IAUDIO_X5_PAD,SANSA_E200_PAD} {\ButtonUp} \opt{IPOD_4G_PAD,IPOD_3G_PAD}{\ButtonScrollFwd} \opt{IRIVER_H10_PAD}{\ButtonScrollUp} & Raise Volume\\ \opt{RECORDER_PAD,ONDIO_PAD,IRIVER_H100_PAD,IRIVER_H300_PAD,IAUDIO_X5_PAD,SANSA_E200_PAD} {\ButtonDown} \opt{IPOD_4G_PAD,IPOD_3G_PAD}{\ButtonScrollBack} \opt{IRIVER_H10_PAD}{\ButtonScrollDown} & Lower Volume\\ \end{btnmap} \end{table}
