External Power Supply/Charger

The external power supply/charger (PSC-pbxU) can also be used to
run the stroboscope continuously from the AC mains (115/230 Vac).

To power the strobe with the external power supply/charger (PSC-
pbxU):

1.

Plug the power supply/charger cable into the recharger socket
(located below the display panel behind the handle).

2.

Plug the power supply/charger into an AC mains wall outlet.

3.

Press (and lock) the trigger switch to operate.  If the trigger switch
is not pressed, the unit will start charging.

Battery Disposal

Prior to disposing of the 

Phaser-Strobe pbx

, 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.
