voltage of the power supply. The voltage indicator will turn red when the unit is powered from it's
internal batteries and if the battery level is to low. The user should then replace the batteries as
soon as possible. The low voltage threshold is set to 13.5V (2 x 6.75V). This threshold is
compatible with rechargeable Lithium-polymer batteries.
6. Batteries compartment. This compartment is designed to receive 9V 6LR61 or PP3 batteries.
Audioroot recommends using alcaline or high power rechargeable lithium-polymer batteries. Please
respect the + and – polarities. Never leave batteries in the unit during storage. Use only first

The FEMTO can be powered thru
this connector with an external
