turn the power OFF and remove the receiver from its air purge.
remove the receiver cover from the front flange.
slacken off the four screws holding side detector PCB to the main body of the
receiver (M4 x 16 screws).
completely remove the four M6 bolts from the end detector PCB.
slide out the gas cell assembly.
replace the gas cell, ensuring that the same orientation is kept – the notch in the
gas cell assembly should be facing away from the side on which the side detector
PCB fits.
reverse the above process being careful not to over-tighten the four bolts (if
these are too tight the gas cell may fracture).
turn the power ON and recalibrate - see
