USING THE EMORTAL BOARD 
BREAK BEAM SENSOR 
SYSTEM 
The Break Beam Sensor System (BBSS) is used 
to detect when a paintball is ready to fire from the 
Etek4. If  no paintball is ready then the BBSS will 
inhibit the Etek4 from firing. This prevents the Etek4 
from ‘chopping’ paintballs that are not fully loaded 
into the marker. 
To switch off  the Break Beam Sensor System, press 
and hold the 
 button for 0.5 second (SEE FIGURE 
3A).
The Break Beam Sensor System indicator on the top 
right of  the LCD will change from 
 (enabled) to 
(disabled).
To switch the Break Beam Sensor System back on, 
press and hold the 
 button for one second. The 
indicator will change back to 
.
When the Break Beam Sensor System is enabled, 
the indicator will change depending on whether the 
system has detected a ball or not. When no ball has 
been detected the indicator looks like this 
, when a 
ball has been detected the indicator changes to look 
like this
