Additional information
HSS
The D2 unit supports HSS (High speed sync) when used with any of
the optional Air Remote TTL transceivers. 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 (e.g. Canon) or in the camera
menu (e.g. Nikon), not on the D2 unit. When HSS mode is used, the
MODE setting indicates HI-S on the D2 display [1].
NOTE
• Frequent use of HSS will have an impact on the life-time of the D2 flash tube.
• Your Air Remote TTL may require a firmware update in order to use the HSS feature.

TTL
The D2 unit supports TTL when used with any of the optional Air
Remote TTL transceivers. With a TTL remote mounted in the camera
hot shoe, you can select to let the camera control the flash output fully
automatically without manual metering.
TTL is selected on the remote, not on the D2 unit. If the camera requires
a flash output outside the range of the D2 unit, the display [1] will blink.
If the ready signal is set to BEEP or BEEP DIM, there will also be a long
beep.
The indicator AUTO is shown on the D2 display [1] every time the flash
output is set automatically by the camera. The indicator is shown for 15
seconds after receiving a TTL flash command from the remote.
