THE MIRROR IS FRAGILE AND MUST BE TREATED CAREFULLY. CLEAN AS FOR ANY
OPTICAL COMPONENT USING A GOOD QUALITY LENS CLOTH.
THE UPPER MIRROR PLATE HAS BEEN DETACHED FROM ITS CABINET MOUNTS TO
PROTECT IT DURING TRANSIT.
TO FIT THE MIRROR PLATE:
1. Lay the cabinet on its back onto a non-scratch surface.
2. Remove the two thumb nuts and two shake proof washers from the studs on the
under surface of the top panel.
3. Carefully unwrap the mirror plate assembly and place over the two studs.
4. The centre thickness adjusting scew must be placed at the upper left hand corner.
5. Hold the assembly in position whilst fitting the two shake proof washers and the
thumb nuts to the studs.
6. Finger tighten the thumb nuts securing the mirror plate assembly in place.
7. Ensure the mirror is clean, removing any smears or dust using a good quality
glass/lens cloth and glass cleaner.
8. Stand the cabinet assembly on its feet ready for the cell to be fitted.

JCF/F Operating Instructions
Fitting the Cell
THE UPPER SCREWS ON THE SIDE MOUNTING BLOCKS ARE COVERED AND MUST
UNDER NO CIRCUMSTANCES BE REMOVED. TO DO SO WILL RESULT IN BREAKAGE
OF THE CELL. TO FIT THE CELL:
1. Carefully unpack the cell onto a scratch proof surface.
2. The cell mounting blocks are fitted to the cell by two screws protected by covers.
UNDER NO CIRCUMSTANCES REMOVE THESE SCREWS.
3. Below the covered screws are holes which allow access to the cell mounting screws.
4. Offer the JCF cell to the cabinet front panel, so that the cell fixing screws which
protrude through the cell mounting blocks, locate into the cabinet front panel holes.
5. Place the Allen key supplied through the left hand 6mm hole and locate into the
captive nut giving the screw 3 complete turns.
6. Next place the Allen key through the right hand 6mm hole and locate into the captive
nut giving that screw 3 complete turns.
7. Continue to tighten the two screws alternatively until the cell is secure.
8. Do not tighten fully as the cell postion needs to be adjusted.
Fitting the Pump Tubing
1. Check that the Drain Tube on the right hand side of the Cell is retained vertically by
its clip.
2. Fit the tube from the pump outlet to the left hand side of the Cell and the tube from the
filter inlet to the right hand side of the Cell.
3. Fill the Cell with fresh, 0.9% saline to within 5mm of the top. There is a small recess
moulded into the top left rear wall of the Cell. Filling to the lower edge of this recess
will give the correct amount of saline.
4. Insert the power supply lead, plug into the electricity supply and switch on.
5. Switch on the pump using the Blue switch and top up the saline in the Cell as the
saline it fills the tubing and filter.
Cell Adjustment
1. Select the base curve measuring function and adjust the cell position by hand until the
measuring cylinder is equally positioned about the left hand edge of the illuminate
centre thickness scale, and is parallel to the screen fixing strip.
2. Tighten the cell mounting screws. DO NOT OVERTIGHTEN.

1. When the cell is correctly positioned the view above will be seen.
2. The top face of the Cylinder should be parallel to the top of the Screen Fixing Strip.
3. The centre line of the Probe to be equally positioned either side of the left hand edge
of the illuminated Centre Thickness Scale.

1. With the contact lens still in position, rotate the Radius Wheel anti clockwise to raise
the Probe up the centre of the Cylinder until the tip of the Probe just touches the
back (concave) surface of the contact lens. In practice the Probe is raised and
lowered slightly a couple of times until the smallest movement of the contact lens
front surface, relative to the lines on the Centre Thickness Scale, is just visible.
2. Read the BCOR directly (in mm) from where the Radius Scale Mark meets the
Radius Wheel Scale.
1. Do not move the Probe from its position following the BCOR measurement.
2. Using the Centre Thickness Scale Adjusting Knob in the top left hand side of the
cabinet. Adjust the image position so that the Screen Thickness Scale aligns with the
front surface image of the contact lens.
3. Leaving the Probe and Centre Thickness Scale in position, transfer the contact lens
(convex side up) into the LEFT: Surface Inspection Cell.
4. Read the centre thickness directly (in mm) from the Centre Thickness Scale at the
image of the Probe tip.
1. Check that the Viewing Mode Switch is to the right.
2. Rotate the Radius Wheel clockwise to retract the probe in the Radius Cell
until the BCOR reading is 9.5mm on the Radius Wheel Scale.
3. Turn the Focussing and Centring Knob to raise the Centring Platform level with the
top of the Cylinder.
4. Place the contact lens, convex side up on the Centring Platform over the Cylinder.
5. Using the Focussing and Centring Knob, raise and lower the contact lens until it
rests symmetrically on the Cylinder.
6. Lower the Centring Platform clear of the image.
7. Examine the edge profile of the contact lens.
