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.

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

choice alcaline or rechargeable batteries.

The FEMTO can be powered thru

this connector with an external
