Power Switch
The power switch is used to control the L1403/L1420 when power is supplied from the rear ‘clip on’ battery plate.
The camera interface plate is NOT switched when fed from the rear battery plate and therefore the camera switch must be
used to control the camera.
When using this external DC power input the L1403/L1420 is NOT switched using the On/Off Power switch. An external
switch on the power supply or battery belt must be used to control the L1403/L1420.
When using this external LEMO connector the switch WILL control the power fed forward to the camera via the camera
interface plate.
