For Your Safety
Do not disassemble or modify
There are high-voltage components inside the unit. Failure to observe this precaution could result in electric
shock or product malfunction. Should the product break open as the result of a fall or other accident, send the
defective back to authorized service center for inspection and maintenance.
Keep dry
Do not handle with wet hands or immerse in or expose to water or rain. Failure to observe this precaution
could result in fire or electric shock.
Keep out of the reach of children
This device contains small parts that may pose a choking hazard. Consult a physician immediately if a child
swallows any part of this device.
Do not expose to high temperature
Do not leave the device in a closed vehicle under the sun or in other areas subject to extremely high
temperature. Failure to observe this precaution could result in fire or damage to the housing or internal parts.
Before using this product
To prevent damage to the product or injury to you or to others, read the following safety precautions in their entirety
before using this equipment. Keep these safety instructions where users can read them for ready reference.
Caution
After 100 times continuous shots at full power, the flash should be cooled down for about 10 minutes.
Overheating will occur if it is used continuously without cooling down.
Do not keep long time in using the modeling lamp, otherwise the modeling lamp will be deformed, and the
flammable accessories such as softbox will get burnt. The flash can be used continuously at full power for 10
minutes, and then it should be cooled down for one minute.
When using a snoot, do not keep long time the modeling lamp on or over frequent flashlight. Overheating will
result in damages for strobe housing and studio light.
Do not touch the lamp cap when the flash or modeling lamp is working, as it will give out heat, leading to high
surface temperature.
Do not touch the two terminals of the tube outlet as there is high voltage inside. Wear insulated gloves when
replacing the tube or modeling lamp.
Avoid sudden impacts as this can damage the flash tube and/or modeling lamp.
Do not flash directly towards naked eyes (especially those of babies), otherwise it may lead to visual
impairment.
Disconnect from the power supply when it’s not in use.
Conventions used in this Manual
This manual is based on the assumption that both the camera and camera
flash’s power switches are powered on.
Reference page numbers are indicated by “p.**”.
The following alert symbols are used in this manual:
The Caution symbol indicates a warning to prevent shooting problem.
The Note symbol gives supplemental information.

The flash output is adjustable from 1/1 full power to 1/128th power in 0.1 stop increments. To obtain a correct flash
exposure, use a hand-held flash meter to determine the required flash output.
Display Flash Duration
Flash duration refers to the length of time that from flash’s firing to reach the half peak at maximum. The half peak
at maximum is usually expressed as t=0.5. In order to provide the photographer with more concrete data, this
product adopts t=0.1. The difference between t=0.5 and t=0.1 is shown in the following picture.

Stable Color Temperature Mode and High-Speed Flash (speed) Mode
Stable Color Temperature Mode or High-Speed Flash (speed) Mode can be chosen in the C.Fn-F1 setting. These
two modes are effective in M/Multi mode and ineffective in high-speed sync mode.
Stable Color Temperature Mode: color temperature ranges within ±200K, which is a good choice for the
photographers who pursues stable color temperature.
High-Speed Flash (speed) Mode: the max flash duration is up to t0.1=1/25640s, which is perfect for capturing the
fast-changing actions. As the color temperature is a little higher in this mode, please set the camera’s white balance
parameter to the proportional color temperature amount (see the chart below) or AWB (Auto White Balance).

● With high-speed sync, the faster the shutter speed, the shorter the effective flash range.
● Multi flash mode cannot be set in high-speed sync mode.
● With high-speed sync, the color temperature is lower (decrease around 700K) because of tube’s characteristics.
Please set the camera to AWB (Auto White Balance).

In this mode, you can set the flash output from 1/128th power to 1/8th power in 0.3 stop increments. With
stroboscopic flash, a rapid series of flashes is fired. It can be used to capture a multiple images of a moving subject
in a single photograph. You can set the firing frequency (number of flashes per sec. expressed as Hz), the number
of flashes, and the flash output.

the flash times. Turn the Select
Dial to set the number.
● Press <SET> Button to select

Press <MODE> button so that

Calculating the Shutter Speed
During stroboscopic flash, the shutter remains open until the firing stops. Use the formula below to calculate the
shutter speed and set it with the camera.
Number of Flashes / Flash Frequency = Shutter Speed
For example, if the number of flashes is 10 and the firing frequency is 5 Hz, the shutter speed should be at least 2
seconds.
● Stroboscopic flash is most effective with a highly reflective subject against a dark background.
● Using a tripod and a remote control is recommended.
● A flash output of 1/1 and 1/2 cannot be set for stroboscopic flash.
● If the number of flashes is displayed as “--”, the firing will continue until the shutter closes or the battery is
exhausted. The number of flashes will be limited as shown by the following table.

Optical S1 Secondary Unit Setting
In M manual flash mode, press <S1/S2> button so that this flash can function as an Optical S1 secondary flash with
Optical sensor. With this function, the flash will fire synchronously when the main flash fires, the same effect as that
by the use of radio triggers. This helps create multiple lighting effects.
Optical S2 Secondary Unit Setting
Press < S1/S2> button so that this flash can also function as an Optical S2 secondary flash with Optical sensor in M
manual flash mode. This is useful when cameras have pre-flash function. With this function, the flash will ignore a
single “preflash” from the main flash and will only fire in response to the second, actual flash from the main unit.
QTII has a 150W modeling lamp which offers 5% to 100% light adjustment and 2 long lighting modes.
Modeling Lamp’s ON/OFF and Settings:

Memory Function
The device is equipped with memory function for the panel setting. It will help remember the panel setting 3 second
after you set it. When starting up the flash next time, the panel setting will be the same as the status before
powering it off.
Tube Replacement
Shut down the power and remove the power cord before replacing the flash tube and wear insulated gloves. Then,
loosen the iron wire on the tube, keep a balanced hold on the two feet of the flash tube and pull out the old tube
gently. Take down the feet casing from the old tube and put it on the new one. Hold two feet of the new tube, and
target directly towards the two copper outlets, then push them slightly in. Twine the iron wire on the stainless steel
sheet to fix the flash tube.

Other Applications
Wireless Control Function
The flash unit is built in with a Wireless Control Port so that you can wirelessly adjust the power level
of the flash and the flash triggering.
To control the flash wirelessly, you need a FT-16 remote control set (on-camera and on-flash). Insert
its receive end into the Wireless Control Port on the flash and insert the transmit end into the camera
hot shoe. Settings made on the hotshoe-mounted transmit and receive ends will be
wirelessly communicated to the flash. Then you can press the camera shutter
release button to trigger the flash. You can also hold the transmit end at
hand to control your off-camera flash.
For full instructions on the use of FT series remote control, see its
user manual.
Sync Triggering
The Sync Cord Jack is a Φ6.35mm plug. Insert a trigger plug here and the flash will be fired synchronously with the
camera shutter.
● Shut down the device immediately when it works abnormally and find out the reason.
● Avoid sudden impacts and the lamp should be dedusted usually.
● It’s normal for lamp being warm when in use. Avoid continuous flashes when it is not necessary.
● Maintenance of all the flashes is up to our authorized maintenance department which can provide original accessories. Users can
replace the flash tube and modeling lamp provided by the manufacturer.
● One year warranty period will be cancelled when any unauthorized maintenance is found.
● If the product had failures or was wetted, it can be continuously used only after it is repaired by professionals.
● Disconnect the power when doing maintenance work or cleaning.
● New changes made to the specifications or designs may not be updated in this manual.
