: Group the remote ash units
.
･ Choose a group (A or B).
･ There is no limit on the number of remote ash units that may be
used. The practical maximum, however, is three per group, as the
light emitted by the remote ash units will interfere with
performance if more ash units are used.

･ See the documentation provided with the ash units for more
information.
･ Test-re the units and conrm that they are functioning normally.
To test-re the units, press the test button on the master ash.

･ Position the sensor windows on the remote ash units to pick up the light
from the master ash. Particular care is required if the master ash is
mounted on a hand-held camera.
･ Be sure that direct light or strong reections from the remote ash units
do not enter the camera lens (in [TTL] mode) or the photocells on the
remote ash units ([
q
A] mode). Otherwise light from the ash units may
interfere with exposure.
･ Even if [––] is selected for [Master ash] > [Mode], the master ash may
emit low-intensity timing ashes. These ashes may appear in
photographs taken at short range. This can be prevented by choosing low
ISO sensitivities or small apertures (high f-numbers).
･ After positioning the remote ash units, take a test shot and view the
results in the camera display.
