FOR YOUR SAFETY
To prevent damage to the product or injury to you or to others, read the
following safety precautions in their entirety before using this device. Keep
these safety instructions where users can read them for ready reference.
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 the authorized service center for inspection and maintenance.
Keep dry
Do not handle with wet hands, immerse in water, or expose to rain. Failure to
observe this precaution could result in fire or electric shock.
Keep out of 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 in 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.
CAUTION
After 30 continuous flashes at full power, the flash should be cooled down for
about 3 minutes. Overheating will occur if it is used continuously without cooling
down.
Do not keep using the modeling lamp for a long time, otherwise flammable
accessories attaching to flash head, e.g. softbox will get burnt. A 10-minute time
is recommended in this case. After 10 minutes, cool it down for 1 minute.
When using a snoot, do not keep the modeling lamp on for a long time or fire too
frequently (not over six times for one minute). Overheating will result in damages
for strobe housing and/or 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 insolated gloves before 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 will not be used for an extended
period.
