1.Turn the etcher on. After approximately 65 seconds, the VUE 5 will turn on.
2.Ensure that the etchant is regenerated ( VUE 5 not pumping chemicals, etchant is clear, emerald green )
3.Physically look at the output and bubble detector light cells to see if any bubbles are present. If so, locate and correct the problem before proceeding.
4.Remove the clear covers of the Chemical Section and disconnect the light cell used for bubble detection. This is the last one in the lower left of the box before exiting as “Etch Out”.
5.Open the front of the Electronic Section. Locate the R1 potentiometer on the Bubble Detector board on the inside of the Electronic Section. Using a very fine slotted screwdriver, turn this potentiometer fully counter-clockwise.
6.Locate the potentiometer labeled R11 and turn the screw until the bubble detector warning sounds and then back off just slightly to turn off the sound or, if the bubble detector was sounding to begin with, turn the screw just until the sound stops.
7.In the Chemical Section, reconnect the bubble light cell disconnected in step 4 and replace the clear covers.
8.In the Electronic Section, turn the R1 potentiometer just until the amber LED on the Bubble Detector Board turns on or off.
