Chapter 4
To obtain best performance from your D-180, please follow these preventative care and
maintenance guidelines.
1) Protect the D-180 from excessive impact shock and vibration. Do not
drop. Do not leave on a vibrating boat deck without some cushioning,
for example. Especially, protect the Optical Sensor. Use some towels
or padding under the arm connector (see figure at right) to prop up the
strobe so there is no pressure exerted on the Optical Sensor/Connector.
2) Do not leave strobe exposed to direct sunlight or other areas of high temperature.
3) Do NOT disassemble or attempt to self-repair. The strobe contains very high voltage
circuitry. Disassembling could lead to severe electric shock and injury. If you think the
strobe is in need of repair, always contact Inon or your Inon dealer.
4) Do not leave the strobe closed when traveling to or from high altitudes, including travel on
aircraft. Always remove the Battery Box Cap.
5) When changing batteries use extreme care to prevent any water from entering the strobe or
battery connection terminals. Where possible, avoid battery changes when the strobe is wet.
6) Limitation on number of continuous repeated strobe flashes
In order to prevent overheating and damage of D-180 flash tubes and internal circuitry, do
not repeatedly discharge the strobe more than recommended limit.
Limit the number of continuous repeated strobe discharges according to the chart below.
After reaching the limit, stop and let the strobe cool off for two minutes minimum. In
general, it is preferable to let the strobe cool off anytime after a continuous burst of flashes,
even if less than the maximum below.

(Main Mode Switch Position)
AUTO Position*, FULL Position
M-2, M-3 or M-4 Positions
*When subject is at far (distant) side of light adjustment range, or shooting conditions
cause the strobe to discharge in the FULL to –0.5 range.
7) Important points regarding battery handling and care
The D-180 uses four AA Alkaline, Nickel Cadmium (NiCad) or Nickel Metal Hydride (NiMH)
batteries.
In general, as batteries are used, the battery voltage gradually decreases and it takes longer for the
strobe to recycle after firing. As the batteries discharge, when using manual flash exposure, the
flash output amount (Guide Number) may become slightly less than actually indicated. As
