OPERATION AS DC CAMERA SUPPLY FROM MAINS

The Tandem will automatically operate as a DC power supply once the camera, or other device is turned on. There are no switches, it is fully automatic. The single green LED will light indicating that the unit is operating as a power supply.

A battery may be attached to Tandem while mounted to a camera. With the camera OFF, the battery will charge. When camera is turned ON, Tandem will supply power to camera remembering the point at which it left charging. When camera is turned off, Tandem will again resume battery charging.

If AC line voltage is removed from the Tandem, and a charged battery is mounted on the unit, power from the battery will be routed to the camera. When AC line voltage is restored, the battery will be re-evaluated for a proper charge routine.

TIP: When camera is used on stakeout, (such as indoors on a tripod) keeping a battery mounted to the Tandem allows instant switching to handheld. Simply remove the power cord for an automatic switch to battery power.

WARNING: DO NOT OPERATE THIS UNIT IN THE RAIN.
