Directives.
1.2 Warnings and caution
• Use the product for its intended purpose
– underwater photography –
following the modes and instructions given by this user guide.
• Do not attempt to disassemble the strobe under any circumstances.
High voltages that can cause fatal electric shocks are present in the
electronic components of it. Any tampering with the flash will void
the warranty. All inspections and repairs must be carried out at
ONEUW’s premises or authorized service centers.

IMPORTANT INFORMATION
• Do not leave the strobe in overheated environments such as car
interiors in summer or boat engine compartments. Do not expose
the strobe in summer directly to the sun for prolonged periods,
overheating can damage the unit and create dangerous situations.
• To recharge the battery packs, use only the specific battery charger
supplied with the strobe, following the appropriate instructions for
use (chapter 5.4). Recharge the battery packs in cool rooms and
avoid overheating when using them.
• If the strobe is flooding turn it off immediately and for your safety
do not use it until reconditioning to technically efficient condition.
Send the unit to our plant or authorized service centers for
inspection. Carefully read the instructions given in this manual in
the relevant chapter (16.0)
• Strictly follow the instructions on how to connect the strobe.
Camera model, wiring mode, single or dual units, interface with
strobes of other brands, are all parameters that should be carefully
checked for compatibility. The strobe and the units connected may
be seriously damaged due to improper connections. Carefully read
the instructions given in this manual in the relevant chapter (14.0).
• Do not fire the strobe directly into the lens of a digital camera, the
camera sensor may become damaged.

BASIC INFORMATION
2.0 Key features overview
ONE160x is a professional underwater strobe with maximum energy of
157 Ws (J) and Guide Number 20 (ISO100-1m-full power). The beam
angle is 130° (GN16).
The body of strobe is machined from a solid block of anticorodal
aluminium, protected by a hard anodizing treatment with nanotech
quartz coating.
The depth rating is 200 m.
The strobe control is entrusted to a pair of powerful CPU that manage,
one the digital communication between the camera and the strobe, i-
TTL protocol by Nikon and E-TTL protocol by Canon, and the other the
power circuits in order to optimize the performances of the unit in
every situation, in addition to operational safety and battery life.
The possibility of firmware upgrade allows us to guarantee, within
hardware limits, the future compatibility with the new digital cameras.
Two large lever selectors, a multifunction rotary control switch and a
wide control display allows us every function to be setted and
monitored.
The left MAIN lever selector operates the control of the pilot light and
the TTL flash light reading mode. The 7-PL-TTL control lamps indicate
the flash readiness, the switching on of the pilot light and the selection
of the TTL mode respectively.

BASIC INFORMATION
The right INPUT lever selector allows us to select input and connection
mode that we intend to use: synchro cable socket, fiber-optic cable
socket, optical receiver on parabolic reflector for slave mode. The
control lamps indicate the selected SYN-OPT-SLV input.
The rotary control switch adjusts power output in manual mode or
exposure compensation in TTL mode. The selected energy level or
exposure compensation are clearly visible in the center section of the
wide display.
The lighting element is a professional and oversized circular flash lamp,
with a slightly warm coating, mounted on parabolic reflector with
dome port.
The strobe is equipped with a LED coaxial pilot light with two power
levels that can be selected manually or automatically with focusing.
Power is supplied by a removable NiMH battery pack rechargeable by
the dedicated desktop battery charger. More than 250 flashes at full
power are ensured with recharge times ranging from 0.1 to 1.8
seconds.
