Select Freeze/Normal mode
The B1 unit 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.

[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].
