Power Connec ons

The Tempest BaseSta on can be powered from AC or DC power. The front panel ON/OFF switch controls AC and DC power

coming into the BaseSta on. If AC and DC are both connected, the DC will act as a power supply backup in the event AC

power is interrupted.

AC Power Connec on

» Always connect the power cord to the Tempest BaseSta on before connec ng to the outlet.

» Only use approved IEC AC power cords.
