The Status LED indicates that the unit is powered on, and displays battery level and other special status modes.
Normal Operation
Under normal operation the LED will display a short green blink every 2 seconds. This is the normal “powered on
and waiting for trigger” blink.

1 Green blink = More than 50% remaining
2 Amber blinks = Warning – less than 50% remaining
3 Red blinks = Less than 25% remaining – change immediately

FlexTT5 "Good Battery" Blink
See the Batteries section for more information.
Triggering
A pulsing red LED in sync with TEST or a camera trigger indicates normal transmission.
Learn Mode
If TEST is held for 10 seconds, LEARN mode will be activated. See Learn Mode for information. A short red blink
in sync with the camera’s trigger indicates normal transmission or reception.

Learning LED sequence: Holding TEST for 10 seconds will cause the unit to pulse red (continuously transmitting),
then it will flash amber 4 times (indicating the beginning of Learn mode), then it will pulse amber while listening for
a channel to learn. If it learns a channel, it will blink green 1, 2, or 3 times depending on the channel learned, then
flash amber 1 more time to indicate LEARN is complete. If no channels are learned, the radio returns to normal
“waiting for trigger” blinking. See LEARN Mode for more information.
Error Condition
Repeated red blinking indicates an error condition. Power off the unit, reseat all connections, and power back on. If
the error persists, verify your settings. For example if you are using a Standard channel to trigger a FlexTT5 with a
Speedlite in it set to E-TTL, this is an error. The flash needs to be set to manual (See Manual Mode for more
information). <videoflash>0lHtF_8HyiE&loop=1&rel=0&autoplay=0&autohide=1|225|155</videoflash>
A normal green blink occurs on power up initialization and after Apply Settings has been pressed in the
PocketWizard Utility.
Note that a single red blink when triggering is normal operation.
