Note: 
After changing any of the settings, press ‘ACTION/RECALL’ to store the new 
value.
DMX address  
Selects the unit’s DMX address (start channel). 
The Atomic Colors uses 1, or 2 DMX channels depending on the fan speed control setting. The 
first DMX channel (start channel) controls the movement of the gel string, and the second 
channel, if remote fan control (Fnr) is selected, controls the cooling fan speed. 
The unit will automatically select the two DMX channel mode if the fan speed setting is set for 
‘Fnr’ (see below), otherwise the unit will remain in single DMX channel mode. 
To change the address, press 
‘UP’ or ‘DOWN’ button once to increment/ decrement the value; 
hold down the 
‘UP’ or ‘DOWN’ button for fast increments/ decrements of the value. 
Fan speed (Fn) 
Sets the speed of the gel-cooling fan, and 1 or 2 channel DMX operation. 
There are four fixed fan speeds levels, ‘Fn1’ being the slowest and ‘Fn4’ being the fastest. The 
‘Fnr’ option allows you to control the fan speed through the second DMX channel. 
Please note that extended operation with low gel-cooling fan speeds may have a detrimental 
effect on the life of the gel string.

Gel saver (GL) 
Toggle the gel saving feature on ‘GL1’ or off ‘GL0’. This feature slowly moves the chosen gel(s) 
back and forward slightly, so that heat from the lamp is dissipated over a larger area. This can 
extend the life of the gel string. 
Note: - Visually check that the gel is correctly positioned before using the gel saver feature. If the 
gel position is not correct, adjacent colors may show, and the joining tape may overheat. 
(See programming notes)
Speed (SP) 
Set the scroll speed. 
Select normal speed ‘SP1’ for quieter operation or fast speed ‘SP2’ for faster color changes.
Display (dP) 
Switch the display on ‘dP1’ or off ‘dP0’. This feature can be used to blank displays that may be 
an unwanted distraction. When off, the display will re-activate when any button is pressed. 
Light activated fan (LF) 
Toggle the automatic, light-activated cooling feature on ‘LF1’ or off ‘LF0’. This setting allows 
the gel cooling fans to be activated by the light output of the Atomic 3000 strobe. When on, light 
from the strobe automatically switches the fans to their set speed, and activates the Gel saver 
function (if ‘GL’ set at 1).
