• AC Power Unit LA-2
Before using the AC unit, make sure the voltage selector is set for the proper voltage. The unit has separate settings for 220 and 240 volts. Insert a small coin in the slot and turn the screw so the slot points to the proper setting (220 or 240) . The 100 and 117 volt settings shown in the photo
(1)cannot be used . To use the 100 or 117 volt settings, take the unit to your nearest Nikon service centre for ad-
justment.
To connect the AC unit, plug one end of the power cord SC-21 into the power socket on the lens barrel by aligning the arrow on the pi ug with the T mark next to the socket
(2). Next, align the white dot on the other end of the plug with the metallic dot near the edge of the LA-2's power socket, and push the plug into the socket until it clicks into place (3) . Finally, plug the AC cord into a wall outlet. When the AC unit is switched on, the pilot lamp on top of the unit lights up immediately. To remove the power cord'splug from the AC unit, grasp the plug by its metal locking ring and pull it out.
Caution 1: The grounding cord (supplied with the LA-2) should be plugged into the ground terminal at the back of the AC power unit to ground the system whenever possible. (See page 21 for details) . Caution 2: Before connecting the power cord SC-21 to or discon- necting it from the LA-2, make sure that the power switch is off. Otherwise, the ringlight might be damaged.
