batteries discharge further, towards complete exhaustion, there will be a sharp reduction in voltage
possibly causing the strobe to function inconsistently.
If you observe any of the following symptoms, it may be that the strobe is not receiving sufficient
voltage necessary for correct function.
When Focus Light brightness becomes dimmer.
When it takes the Strobe Ready Red Lamp over 30 seconds to shine when using alkaline
batteries;
Or, when the Strobe Ready Lamp recycle time takes over 8 seconds for NiCad batteries.
In general, battery performance will decrease as temperature lowers, and batteries will slowly
discharge over time when not used. And, number of possible flashes can greatly vary based on
variables such as water temperature and how the batteries are used. If possible, start with a fresh
or sufficiently charged set of batteries so that you do not end up with exhausted batteries in the
middle of a dive, and loose important imaging opportunity.
Follow these precautions to avoid damage to batteries and strobe, and depending on the type of
batteries, possible buildup and explosion of flammable (hydrogen) gas.
Warning: Equipment damage or personal injury may result if these precautions are not
followed.
A. Make sure battery +/- positions are properly placed in Battery Box.
B. Do not use non-specified batteries, such as Lithium or Manganese batteries.
C. Do not mix batteries from different manufacturers, or batteries having different remaining
charges.
D. Do not mix different battery types together, such as Alkali and NiCad.
E. Do not attempt to charge non-chargeable batteries.
F. Do not intentionally short the batteries or circuits.
G. Do not store batteries in D-180 when not in use.
H. Do not use battery charging devices that are not compliant with the battery manufacturer's
recommendations.
I. Do not repeatedly fire the D-180 to discharge/refresh rechargeable batteries, or any other
time.
Caution: Never repeatedly fire the strobe continuously, for example, to discharge or
refresh the batteries. Repeatedly firing the strobe will cause overheating and damage
internal components.
Caution: If any water ever enters the Battery Box, or if you ever feel suspicion that the
D-180 is not operating correctly:
1. Immediately stop using D-180.
2. Promptly remove batteries.
