Charging
C5D uses smart Li-Ion recharging technology, with typical charge time of 2-4
hours. Connect a mini-USB cable from any computer or USB power adapter and
set charge switch to
CHG
position to begin charging.
C5D may be used while charging, and USB cord may be connected or
disconnected as desired.
Set charge switch to
BAT
position when listening via USB from a phone or tablet. BAT position disables
charging so that C5D consumes no power from your device.
