READ ME FIRST:
UPDATE FIRMWARE: Be sure to upgrade all your PocketWizard ControlTL radios (including
this one) to the latest rmware for proper functionality.
All equipment should be turned OFF when making connections; unwanted triggering or other erratic
behavior may occur.
The rst exposure after making initial connections or powering on may not be properly exposed and ash
power levels may not be set as expected. Always test at least twice.
All information in this Quick Guide is subject to change. Visit www.PocketWizard.com/support
to nd the latest ash and features compatibility, Quick Guides, and Owner’s Manuals.
To use your PowerST4:
1. Connect the PowerST4 to your RX ash pack
via the remote port, then power on the ash.
2. Select Zone A, B, or C with the Zone Switch
on your PowerST4. Default = A
3. Set up your PocketWizard transmitter and
take pictures normally.
Make sure all your radios are set to the same
PocketWizard channel. See the Learn Mode and
PocketWizard Utility sections for more information
on channels. Default = ControlTL 1
The Status LED blinks green every few seconds to
indicate normal operation. It will blink red in sync
with a trigger.
Momentarily pressing TEST/LEARN will
test trigger the ash. See the Learn Mode and Reset
sections for more information on those functions.
NOTE: The PowerST4 overrides settings you make directly on your ash. If you would like to change the beeper,
modeling light, or optical slave mode on your ash, just set those features on your ash before you turn on your
camera’s transmitter. You can also adjust these settings from your transmitter via the PocketWizard Utility. See that
section for more information.
If you would like the ash to simply trigger at the output power you set and not accept changes from the radio, follow
these steps: before turning on your transmitter, change your ash power level then press TEST on the PowerST4 and
wait for 3 amber blinks. Allow a few seconds between each step.
To allow the PowerST4 to control the ash features again, turn the ash OFF and back ON.
If you have a ControlTL transmitter like the MiniTT1 or
FlexTT5 then you can control your ash’s output level
remotely. Add the AC3 ZoneController for even more
control.
Read the PowerTracking section for more information on
using the PowerST4 when no AC3 is present, or when using
an AC3 in Auto Mode.
In AC3 Manual Mode, the AC3 Power Dial sets the ash
power output as shown in the table on the right.
The numbers in the table are within +/- 0.1 stops.
You can use any PocketWizard ControlTL receiving radios
together in the same exposure.
Remember that studio and manual ash output will not
be calculated as part of an E-TTL / i-TTL exposure.

PowerTracking
PowerTracking allows you to adjust your remote studio ash’s output power via the
camera’s FEC, ISO and aperture controls.
PowerTracking happens automatically when you have a MiniTT1 or FlexTT5 on
a Canon or Nikon camera and you are controlling a compatible studio ash with a
PowerST4 connected.
Center Point: The center point for PowerTracking is 3 stops down from your ash’s
maximum output power. All PowerTracking adjustments are based on this center point.
For example, if your ash’s maximum output power is 6.5, then the center point is 3.5.
PowerTracking with your camera’s controls: If there is no AC3 ZoneController on your transmitter, ash output
power on your remote studio ash will track up and down with FEC changes on your camera. Zero (0) on your
camera’s FEC control is the center point and equals 3 stops down from your ash’s maximum output setting.
Adjust FEC to raise or lower your ash power per the table on the previous page. See Camera FEC Range section
for more information.
Nikon: With no AC3 ZoneController on the transmitter, only the camera’s FEC control will
adjust ash power output level.
Canon: With no AC3 ZoneController on the transmitter, the camera’s ISO and FEC controls will
adjust ash power output level. The ISO in use for your rst picture will be used as the center point
for PowerTracking.
In the PocketWizard Utility for your transmitting ControlTL radio, this is called Full Manual and is the default operation
for PowerTracking when no AC3 ZoneController is in use. See below for settings in the PocketWizard Utility that allow
you to customize PowerTracking to also use your camera’s aperture controls for Canon and Nikon, or ISO controls
for Nikon.
