*Go to „OPERATION-ADVANCED" screen, press „Change Tape" button and follow the instructions on the screen
or follow step-by-step procedure described below.
1. STOP the measurements, open the front door.
2. Loosen the thumb screws and remove the transparent plastic covers from both the left-hand and the right-hand side
spool.
3. Using thumb and fingers on both sides of the optical chamber, lift the chamber upwards against its springs and lock it in
place by pushing the metal latch. Remove the used tape from both axles.
4. Take the new filter tape and place it on the left axis. Take note of the metal spring leaf which stabilizes the top surface of
the roll. Take the other cardboard spool and attach the end of the filter to it using adhesive tape. Place the empty on the
right spool axis.
5. Make sure that the tape is fed beneath both the left and the right guide posts, and passes under the optical chamber.
Release the optical chamber by lifting up with thumbs and fingers on both sides.
6. Replace both transparent plastic covers. Tighten the thumb screws by hand only. Check that the left spool can turn
freely. Make sure that the right spool is firmly clamped to its axis: test by gently pulling the tape, and make sure the spool
center does not move.
