B2 250 AirTTL Set light output in manual mode (Energy level) The output of the flash light is shown in a relative f-stop scale in the light output setting section [24] on the display. The maximum energy (250 Ws) is shown as 10.0. To change the energy level of the connected flash light, use the corresponding ENERGY/ SETTINGS dial [13] or [14]. The setting can also be done on the optional Air Remote TTL, Air Remote or Air USB.

The modeling light is turned on and the unit beeps when it is ready to flash again. • Blank: No ready signal.
Battery status and charging The battery status is indicated by the battery level indicator [26] on the display. The battery status can also be checked by pressing the CHECK button [19] on the battery pack. See also section Technical data. B2 250 AirTTL Handling For optimal performance, the battery should be fully charged prior to usage. The battery can be charged while in use and from any charge level. Only use the Profoto Battery Charger 2.8A or the Profoto Car Charger 1.8A.
B2 250 AirTTL Mounting on a special stand/grip or camera flash bracket: 1. Unscrew the stand attachment screw [35] and remove the stand attachment. 2. Thread the lamp head onto the special equipment. Note that the thread size of the B2 lamp head is 3/8” and that a 1/4 thread insert may be needed for some grips and brackets. Mounting Profoto Light Shaping Tools The built-in reflector of the B2 lamp heads creates a wide and even light spread with a high output.
1. First align the two white square dots on the lamp head plug (male), with the dot on the extension connector (female). B2 250 AirTTL Extension cable connection The extension cable is connected in the same manner as the lamp head. 2. Push the plug (male) all the way into the connector (female). 3. Secure by turning the ribbed locking ring on the lamp head plug clockwise. 17 To protect the connectors of the extension cable, it is appropriate to connect the plug to the outlet of the cable.
B2 250 AirTTL 18 Other HSS Profoto B2 supports HSS (High speed sync) if used with any of the optional Air Remote TTL tranceivers (currently available for Canon and Nikon). HSS enables shooting with flash at a faster shutter speed than the fastest external flash sync speed (x-sync) of the camera. This option can be extremely useful to limit the influence of ambient light when shooting in bright conditions. HSS is either selected on the remote (Canon) or in the camera menu (Nikon), not on the flash.
B2 250 AirTTL Temperature limit indicator The temperature limit indicator [31] is lit if the B2 has reached a temperature level that has activated the built-in over-temperature protection. When this occurs the performance is limited until the temperature level is back to an acceptable level. Note that the battery has a stand alone temperature protection that may be activated without the temperature limit indicator [31] being lit.
