3.2 Controls and indicators
3.2.1 Overview
3.2.2 Power
The power supply for the camera and its adapter is normally supplied via the transmission
cable coming from the base station. The Power On indicator lights when power is supplied and
the camera power switch is set to the on position
.
When power is supplied via the transmission cable, an output power socket supplies 12 VDC,
1.5 A maximum for powering accessories.
It is also possible to operate the camera without a transmission cable by supplying a 12 VDC
supply to the DC input socket. The BATT indicator in the viewfinder lights if the camera supply
voltage is less than 11.5 VDC when using an external supply.
If excessive current flows in the camera or adapter, the circuit breaker trips and shuts off
power to all the units. If this happens check the units for faults and if necessary take corrective
actions before pressing the circuit breaker button to reset the power.
