SenSor SYSteM
The Break Beam Sensor System, referred to elsewhere 
in this manual as ‘BBSS’ is used to detect when a 
paintball is ready to be fired from the Etha. If  no 
paintball is ready then the BBSS will inhibit the Etha 
from firing. This prevents the Etha from “chopping” 
paintballs that are not fully loaded into the marker. 
When the Etha is powered up, the BBSS is 
automatically enabled. The current state of  the BBSS 
is displayed by a flashing LED on the navigation 
console. 
To switch OFF the Break Beam Sensor System, push and 
hold the select button 
 for 0.5 seconds. The LED on 
the navigation console will flash purple indicating that 
the Break Beam Sensor System has been disabled. 
To switch ON the Break Beam Sensor System, push and 
hold the select button 
 for 0.5 seconds. The LED on 
the navigation console will flash either yellow (no ball 
detected) or light blue (ball detected) indicating that 
the Break Beam Sensor System has been enabled. 
Additional features of the Etha Break Beam Sensor 
System are covered in the ‘Understanding the BBSS 
Operation’ section on Page 30 of  this User Manual.
