[. . . ] If the conditions change, the amount of the exposure compensation will need to be changed correspondingly. Naturally, data calculated on land will not be applicable to underwater photog raphy. 18 Synchro Socket ® To connect the sync cord @) to the speedlight, remove the synchro socket cover ® by turning it counterclockwise and pulling it up. Remove the dust-proof plastic cap from the sync cord 's speedlight plug @ (black). Insert the speedlight plug into the synchro socket after aligning the synchro socket index CD with the red index on the speedlight plug . When the speedlight plug is inserted, turn its locking ring clockwise as far as it will go to secure the plug . Never submerge the speedlight in water with the synchro socket cover removed or get the sync cord plugs wet. Always make sure either the synchro socket cover or the sync cord plugs are securely attached before entering the water. After shooting underwater, wipe off any water droplets with a soft cloth before removing the plug to prevent water from entering the socket. Whenever the sync cord is not being used or the speedlight is bei ng washed with the sync cord removed from the synchro socket, attach the synchro socket cover to protect the socket. To attach the socket cover press it against the socket to seat the O-ring , then turn the locking ring clockwise as far as it will go. • To simplify identification, both the tip of the sync cord's speedlight plug and the inside of the synchro socket are color· coded yellow. Sensor Socket (]) To connect the sensor cord to the speedlight for nonTTL automatic flash control , remove the sensor socket cover @ by turning it counterclockwise and pulling it up. Remove the dust-proof plastic cap from the sensor cord 's speedlight plug (black). Insert the speedlight plug into the sensor socket after aligning the sensor socket index @ with the red index on the speedlight plug. When the speedlight plug is inserted, turn its locking ring clockwise as far as it will go to secure the plug. Never submerge the speedlight in water with the sensor socket cover removed or get the sensor cord plugs wet. Always make sure either the sensor socket cover or the sensor cord plugs are securely attached before entering the water. After shooting underwater, wipe off any water droplets with a soft cloth before removing the plug to prevent water from entering the socket. Whenever the sensor cord is not being used or the speedlight is being washed with the sensor cord removed from the sensor socket , attach the sensor socket cover to protect the socket. To attach the socket cover, press it against the socket to seat the O-ring, then turn the locking ring clockwise as far as it will go. • To simplifty identification, both the tip of the sensor cord 's speedlight plug and the inside of the sensor socket are color-coded black. 19 CONTROLS IN DETAIL-continued _ _ __ Sensor Unit SU-101 (Optional) In combination with the optional Sensor Unit SU-101, the S8-102 provides non-TTL automatic flash exposure control. With the S8-102 's shooting mode selector switch ® at "AUTO, " the Sensor Unit SU-101 reads the light reflected back from the subject while the speedlight is firing and tells the speedlight to turn itself off when the light output is sufficient for correct exposure. The selector dial on the back of the SU-101 allows one of two aperture settings to be selected. Normally, the SU-101 is attached to the camera's accessory shoe. However, when a plastic frame finder or optical underwater viewfinder is mounted on the camera's accessory shoe, the optional sensor holder is used to attach the Sensor Unit SU-101 to the speedlight bracket. Mounting the SU·101 on the camera : Turn the sensor unit's locking wheel counterclockwise as far as it will go, slip the unit 's mounting foot into the camera's accessory shoe, and turn the locking wheel clockwise to tighten it. [. . . ] However, the re cycling time and the number of flashes per battery set depend upon the age of the batteries, their charges , and their capacities. not continue to use NiCd batteries after they are exhausted. Continued use may reduce their life span or cause leakage. o Before charging, thoroughly read the battery and battery charger instructions. oCharging should only be done for the designated number of hours on a battery charger recommended by the battery manu· facturer.
