Installing the batteries
A Before installing the batteries, please
check that the power switch is in the "OFF" 
position. To unlock the battery compartment, 
push lightly on the center of the cover. 
B To open the battery compartment push and
slide the cover downward as shown.
C Insert four “AA”-size batteries into the
battery compar tment, ensuring that the 
polarity indications “+” and “-” are positioned 
correctly. The batter y compar tment is 
designed to prevent incorrect insertion. The 
PZ42X will not operate if the batteries are 
installed incorrectly. 
D Press the battery cover in and forward,
until it snaps into place. When the unit is 
switched on, it will start charging with a 
slight humming sound and the "Ready 
Light" will come on when charging is 
completed. 
E To turn the power off slide the switch to the
"OFF" position. The "Ready Light" will go off 
and the unit will not flash. 
* Before mounting the flash unit onto the camera, please turn the flash unit off. If it
is turned on, the flash unit may self-fire, or damage the flash unit may result.
We recommend that you use Sunpak rechargeable NiMH (nickel metal-hydride)
batteries when possible. They provide shorter recycling times, an increased 
number of flashes per set, as well as energy-saving benefits. 
* The flash is ready to fire as soon as the Ready Light is lit. However, full power
will not be available for several seconds. We suggest that you wait a few seconds 
after the Ready Light activates to achieve maximum output. 
* If it takes longer than 30 seconds for the "Ready Light" to come back on, when
the flash is fired in Full Power Mode, replace the batteries with a fresh set.
Mounting the PZ42X to the camera
Automatic Power Save
In order to save battery life, the Auto Power Save function automatically turns the 
indications off and disables light emission (by stopping charging) when the unit is 
left unoperated for about 15 minutes with the power switch ON. 
To reactivate the unit, press the camera’s shutter button halfway or turn the power 
switch “OFF” then “ON” again.
* A small amount of power is consumed even when the unit is standing by in the
Auto Power Save function. Be sure to set the power switch to “OFF” when you 
are not going to use the unit for a long period.
* When mounting or detaching the PZ42X from the camera, always make sure the
ON/OFF Switch is to the "OFF" position, or damage may occur.
ᱺ Slip the unit onto the camera's hot shoe. Turn the knurled lock ring to firmly affix
the flash unit.
ᱻ When the PZ42X is used with cameras, the shutter speed is set automatically.
When used with other cameras, please set the shutter speed to the appropriate 
flash sync speed (check your camera manual).
