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

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.
