Test Function; Memory Function - Profoto D4 1200 Air User Manual

Test function

The Test Button [18] is used to test that all light settings are correct and that the functionality
is as expected. When the Test Button [18] is pressed, the generator will flash and the Ready
Lamp [18] will turn off while recharging. When the recharge of the generator is completed,
the Ready Lamp [18] will turn on again.

Memory function

The current settings (energy level, modeling light, ready signaling, sync/remote and radio
settings) are automatically saved in the memory of the generator (memory A). Chosen
settings for auxiliary functions are also saved automatically, but they have to be activated
again after the generator has been turned off.
15
In addition to the automatic saving, it is possible to save up to three combinations of
settings in memory B-D. This makes it easy to repeat even the most complex setups.
When recalling saved settings from memory B-D, auxiliary functions are directly activated.
At start up, the D4 Air generator always applies the settings that were in use before the
generator was turned off. To apply the settings in memory B-D, the settings have to be
recalled from the memory. For instructions on saving/recalling, see page 20.
Automatic safety functions
The D4 Air generator is equipped with an effective cooling and safety system. The
integrated fan will automatically start running when the generator is operating at higher
energy levels or when the generator is used in hot environments.
If there is risk for overheating of the generator, caused by abnormal external influence, the
protective system will automatically protect the generator from damage. The protective
system will slow down the recharging intervals and eventually the recharging will stop
completely. After a while, when the temperature has decreased sufficiently, the generator
will start recharging at a normal pace. This automatic protection will only interfere under
extreme conditions such as when the air vents are blocked.
If a defective flash head – for example with a broken or misfiring flash tube – is used, there
will be a long beep signal and " - - - -" will be displayed in the corresponding Energy Display
[10] after the release of a flash to indicate malfunction/underexposure.
NOTE:
The air vents of the generator must never be blocked or covered in any way. Never store your flash equipment in a car
on a hot and sunny day. Never use a D4 Air generator that is placed inside a case or transport box. Avoid storing the
generator close or below the freezing point, which can lead to loss of capacity (flash output) and risk of condensation
when used in a warmer surrounding immediately. Do not expose any flash equipment to wet or humid environments
or extreme electro-magnetic fields.
