Speed key
Flash duration t 0.1 and charge time are reduced by pressing the speed key (17). Therefore, Scoro power packs are optimised for the shooting of moving objects and / or fast image sequences. As soon as the speed key is activated, the corresponding LED lights blue and the maximum flash energy of A2 models is reduced from 1600 J to 1200 J, and the energy of A4 models is reduced from 3200 J to 2400 J. In speed operation, the colour temperature is fractionally colder, however, consistent over the energy adjustment range. The display of the maximum output (12) can be adjusted with the function "max. display"
(see section 14.22).

User key
When the user key (18) is "on" it activates the initial settings of a further operator. With this, Scoro A power packs can be individually configured for two users in which all the relevant functions and settings are separately stored, thus providing independent preference capabilities for multiple users. Those functions, which are stored in standard or user mode, are shown in the two columns “mem” (memory) and "Standard/User" in chapter 14.

Memory functions
In standard and user mode, there are each four own memories available. All the unit settings can be stored therein (see LCD function "memory 1-4" section 14.21). Selecting one of the four memories redirects to an information window in the LCD, in which the most important data of the corresponding memory are indicated. Pressing the "recall" key reinitializes the data in the memory. Pressing the “store” key overwrites the memory contents with the latest unit settings. Those functions, which are stored in standard or user mode, are shown in the two columns "mem" (memory) and "Standard/User" in chapter 14.

Reset key
→ Brief pressure on the reset key (19) advances the cursor directly to the main page. When pressing the menu key (22) the cursor returns to the beginning of the main menu.
→ Pressing this key for approximately 2 s resets the flash additional functions (see section 14.9). This is confirmed by a double-beep tone.
→ Pressing this key for approximately 10 s resets all the functions to the factory settings. This is
confirmed by a double-beep tone.

Alternate release
This function enables to realise even faster shooting sequences. Alternate release also enables shorter sequences, four times faster, even with higher energy (see LCD function “Alternate” section 14.8). With the same function it is possible to reduce the interval of stroboscopic sequences down to a minimum of 0.01 s (see section 14.6)
