Care instruction
To clean the unit, wipe with a soft cloth moistened with a little mild
detergent. Use another soft dry cloth to wipe dry.
Overheat protection
A temperature limit indicator is shown on the main screen of the
display [9] if the B10X/B10X Plus has reached a temperature level
that has activated the built-in overheat protection. When this occurs,
the performance is limited until the temperature level is back to an
acceptable level.
Quick burst
Quick burst is an automatically activated function that allows a series
(burst) of flashes to be fired at a faster pace than the B10X/B10X Plus
can recycle. The function is only active when the light output is set to
less than full. The length of the burst, in numbers of flashes, depends on
the repetition rate and the set light output. The lower the light output is
set, the longer bursts can be triggered. Thanks to this feature, the B10X/
B10X Plus can trigger up to 20 flashes per second on lower power
output without losing light after the first flash. Note that the accuracy
of the light output is slightly less precise when Quick burst is active.
Serial number
The serial number is printed on the B10X/B10X Plus unit, underneath
the battery pack. You can also find the serial number in the display[9]
under SETTINGS>ADVANCED>ABOUT.
