Changing the Setpoint at the
Applicator
To change the setpoint at the applicator, the ap-
plicator must NOT be triggered. By pushing the
kV button on the rear cover of the applicator, the
setpoint will change. If there are 2 green lights lit,
setpoint 1 is active. If 2 green lights and 2 yellow
lights are lit, setpoint 2 is active. If all lights are lit
