6. Push the SETTINGS button [6] to return to the main menu. Otherwise, the
display will automatically return to the main menu after a few seconds.
Display orientation
The setting display orientation rotates the display information 180
degrees. This can be useful if the D2 unit is mounted upside down.
Auto on mode
To make the D2 unit operational, you normally connect the power cable
and then push the ON button [4]. By enabling auto on mode, the D2 unit
18
will be operational directly when the power cable is connected.
Speed
Reduced recycling speed should be enabled when the D2 unit is
connected to a weak power supply network or appliance, for example
a battery inverter like the Profoto BatPac.

Automatic safety functions

The D2 unit is equipped with an efficient cooling and safety system.
The integrated fan automatically adjusts its speed to the internal
temperature and cooling needs. The fan may run even when the unit is
not in operational mode (the power supply indicator [3] is red).
The protective system will automatically protect the D2 unit from
damage if it is exposed to abnormal external influence. The protective
system will slow down the recharging intervals and eventually the
recharging will stop completely. The protective system may also turn
off the modeling light. This automatic protection will only interfere
under extreme conditions, such as high ambient temperatures or
if the air vents are blocked. When the temperature has decreased
sufficiently, the unit will start recharging at a normal pace.
NOTE
Do not block or cover the air vents of the unit. Do not operate the unit in a small enclosed
space, such as a case or transport box. The lack of ventilation can reduce the life-time of
the unit. Do not keep the unit in abnormal temperatures, for example in a car on a hot and
sunny day. Avoid storing the unit close or below the freezing point. A cold unit may not work
properly or may even fail and will lose capacity (flash output). There is also a risk of failure
because of condensation when a cold unit is moved to a warmer surrounding. Do not expose
any flash equipment to wet or humid environments or extreme electromagnetic fields.
