2.0 PREPARATION FOR USE

The Strobe may be hand held or mounted on a tripod or other user supplied
bracket using the ¼-20 UNC bushing at the base of the handle.

2.1

Power

The AC powered strobe must have its power cord plugged into an AC
outlet (115Vac or 230Vac).

The battery powered strobe has internal rechargeable batteries.  The
unit should be charged before use (see section 7.0).  The actual operating
time of the stroboscope depends on the flash rate and duty cycle of
operation.  Slower flash rates (below 4,000 FPM) increase the operating
time.  Note that the strobe will not operate from the recharger supplied
with the unit.

2.2

Input / Output Connections

The strobe has input and output jacks on the left side of the stroboscope.
These can be used for external triggering or synchronization (daisy
chaining two or more strobes). These jacks accept 1/8" (3.5mm) phone
plugs (input - stereo, output - mono).  The input and output are TTL
compatible.  See Figures 2 and 3 for connector connection detail.

Battery Disposal

Prior to disposing of the battery-powered strobe, the user must remove
the Nickel Metal Hydride batteries.  To do this, remove the lens,
reflector and lamp as detailed in the Lamp Replacement section.  This
will expose four (4) screws that must be removed so the reflector
housing can be dismantled.  There are four (4) additional screws in the
case half opposite the input and output jacks that must be removed.
The case halves can now be separated, exposing the batteries.  Remove
the cables from the batteries and place tape over the battery terminals
to prevent them from shorting.  The batteries should be sent to a
recycling center or returned to the factory.  The rest of the parts may
now be disposed of.
