Power Output Control
The Select dial (14) varies the power output, setting the light requirements as needed. The power
is adjustable in thirds of a stop from 1/16 to 1/1, in increments of tenths of a stop, clearly shown
on the LCD display (10). “--” on the display indicates that the flash triggering function is turned
off. Press the Test button to discharge power quickly when the flash output is adjusted from high
to low. The red ready light (13) flashes to indicate energy bleed status until the power setting is
reached.
Test Button
To fire the flash without taking a picture, press the test button (4). It can also help adjust the flash
brightness when combined with the select dial (14). Press the SET button and turn on the flash to
sample the power of the light.
Sync Triggering
The sync cord jack (2) accepts a Φ3.5mm plug. Insert a trigger cord plug to fire in sync to an
attached camera’s PC socket.
GR/CH Button
A short press on the GR/CH button can adjust the monolight’s wireless group. When the group
indicator on the LCD panel is blinking, turn the select dial to change. A long press on the GR/CH
button adjusts the wireless channel. When the channel indicator on the LCD panel is blinking, turn
the SELECT dial to change. Press the SET button (14) to set the value. Make sure that the Transmit-
ter and Slave units have the same values.
Optical Slave Trigger Modes
Three optical slave triggering modes are available and can be set by pressing the slave mode
button (6).
• No optical slave control:
S1 or S2 is not displayed on the LCD panel, indicating the slave trigger-
ing function is shut down.
• First Flash Trigger: S1
is displayed on the LCD panel, indicating the strobe will fire immediately
when the sensor sees another flash fire. In this mode, the flash can function as an slaved lamp,
offering various effects of light and shadow.
• Intelligent Slave/Second Flash Trigger: S2
is displayed on the LCD panel, indicating the optical
sensor will ignore the pre-flash sent by a TTL flash and fire on the second flash of a TTL speedlite.
In this mode, the flash can function as an slaved light to a TTL based system. The light output is
always set manually on this Studio 300/400 R2 monolight.
