USER MANUAL
SDR-400
INTRODUCTION
Thank you for choosing the Raya SDR-400 Alpha
Monolight. This all-in-one, fan-cooled 400w/s
monolight uses intelligent technology, creating a sleek,
compact, and easy to use flash unit. Constructed with
a high-quality rubberized polymer housing, the SDR-
400 is operated with a clearly marked digital control
panel, creating a simple and intuitive workflow for
controlling everything from power levels in one-tenth
stop increments to the built-in wireless receiver.
The durable SDR-400 has an integrated four-channel
wireless receiver that communicates with an included
wireless transmitter. You can easily change the
wireless frequency of the monolight with DIP switches.
Additionally, the monolight includes five individual
slave settings, ranging from a regular slave mode to
modes that will trigger the unit with external flashes
with up to three pre-flashes.
The Raya SDR-400 Alpha Monolight is equipped
with advanced protection circuit controls to prevent
several types of common high-voltage electronics
issues, including over-heating, over-volting, and over-
charging.
This Raya studio flash is ideal for photography
enthusiasts looking for an economical high-powered
flash unit with the convenience of wireless triggering.
The unit’s auto-seeking multi-voltage (100~240V,
50/60 Hz) circuitry and compact construction make
this monolight ideal for local and international use (an
AC plug adapter will be necessary for use outside the
U.S. as well as a 220-240V modeling lamp).

PREPARING FOR USE
The Raya SDR-400 includes a user-replaceable flash
tube and modeling lamp. Be careful not to touch
the flash tube with your
bare hands since this could
cause damage to it. Please
