1. To switch on the unit, press and hold down the TEST button [15]
until the Display [13] shows the settings information.

until the Display [13] is all black.
When the B1X is switched off, the current settings are stored and will
apply when the flash is switched back on again.
Note:
The B1X automatically turns into sleep after 30 minutes and shuts off completely after 60 minutes of inactivity
to save battery life. The auto power off after 60 minutes can be deactivated from any of the optional Air Remote
controls by pressing “HEAD” on remote. This will set the B1X into a deep sleep mode that will continue until the
battery is drained or until the B1X in reactivated by pressing “HEAD” on remote or by pressing any button on
the B1X.
The option to deactivate auto power off can be very useful if the lights need to be set up prior to a shoot in a place
where they later cannot be reached. Note that a fully charged battery will will drain in approximately 50 hours in
deep sleep mode (measured in room temperature).
Normal vs. Freeze
The B1X can operate in two modes to maximize the versatility in
different shooting situations.
• Normal mode: Optimized color temperature stability over the
entire energy range. Best option for most types of shots.
• Freeze mode: Optimized for shortest flash duration. Best option for
shots where the flash is used to freeze fast action.
Switch between Normal/Freeze mode by pressing and holding the
ENERGY/SETTINGS dial [16] and then shortly pressing the TEST
button [15]. When Freeze mode is selected, the Freeze mode indicator
[24] is shown on the Display [13].
