Notes

o When a roll film holder is attached to the camera in mid-roll, you must momentarily push the

Power Drive Grip’s ‘START’ Button to advance the film to the next frame and cock the

shutter.

o After the last exposure, the Power Drive Grip will completely wind the film on the take-up

spool.

o A flickering LED on the Power Drive Grip indicates a low battery condition, indicating that the

batteries need to be replaced.

o In cold weather, battery performance may lower and affect the performance of the Power

Drive Grip. In this condition, if the film fails to advance to the first frame, momentarily move

the Operating Indicator (1) to its ‘START’ position.

o If you are not going to use the Power Drive Grip for some time, remove the batteries.

o Keep the Power Drive Grip’s electrical contacts free of dirt and other contaminates.

o Wrist Strap – If you are going to use the Wrist Strap, attach it to the Neck Strap Lug before

attaching the Power Drive Grip to the camera body.
