MD
(synchronization with motor drive)
At
the motor drive (MD) setti
ng
, the 88-16
is
able
to
recycle fast enough to synchronize with a motor-driven
camera firing continuously
up
to four frames per second.
It
is
po
ssi
ble
to
tak
e
up
to eight flash pictur
es
in
rapid
successi
on
in
this way.
At
the
MD
setti
ng
, only the main
flash head fires
and
the light output
is
approx. one-
sixteenth that of the flash unit's maximum power.
Like
the M
se
tting, this
se
tting
is
al
so
for manu
al
operation ;
therefore, the exposure should
be
calculat
ed
manually
using the
ex
po
su
re
calculator dial or guide number
equation shown on page
30.
Note: As sufficient power
is
required for the flash unit
to
synchronize
with
a motor drive, use the newest and freshest batteries whenever
possible. For the same reason, avoid tripping the shutter immediately
after the ready-light comes on, but wait for at least
30 seconds before
beginning the motor drive sequence.
