Sunpak PF20XD - Handbuch (Seite 6)

Precautions for use
(1) The slave sensor detects light reflected from the
subject, so that synchronous flash occurs. Too little
reflected light may prevent synchronous flash
(2) If the strobe built in your camera provides enough
light, using SUNPAK may cause excessive exposure.
Use SUNPAK only if the built-in strobe does not produce
enough light.
(3) The slave function cannot be cancelled even when
SUNPAK is attached to the hot shoe
(4) When SUNPAK is in use, it may provide synchronous
flash if another strobe flashes.
(5) The automatic sensor, which is at the front of
SUNPAK, is essential for determining the appropriate
exposure. Keep the sensor clean. Do not cover the
sensor when using your camera.
(6) Be sure to use SUNPAK within the effective distance
range of the automatic flash.
(7) If there is anything with high reflectivity (such as a
white tablecloth, flower, or ornament) near the subject,
insufficient exposure may result.
(8) Set the mode dial to a predetermined position. If not,
the proper flash is not provided.
(9) To prevent SUNPAK from deteriorating, limit the
number of continuous flashes to ten when the mode dial
is in the MAX position. When firing ten flashes in such a
manner, wait for ten minutes before firing another flash.
