Check the firing resistance of the device is 510 ± 200 ohms and ensure
end of line monitor is a 3k3 resistor or active end of line device.
Head removal not working.
Check compatible base is being used and is wired correctly. Either a
zener clamp base with a 3k3 end of line resistor or a schottky diode
base with an active end of line device must be used. If an active end of
line device is being used, check that the capacitor is fitted at the sense
zone terminals.
