APPENDIX ‘A’ (cont’d)
Replacing the Faceplate
The tuner faceplate fits precisely on the chassis. The buttons will move freely in their respective cutouts when it is installed correctly. This can be done with a little care patience
and care. Just remember, the necessity to make very slight adjustments of the faceplate's position is important. If you move it too far in any one direction you will end up
having to spend more time making the necessary adjustments so it will not bind on the pushbuttons.
1. Ideally, you will have the tuner in a position so that it can rest on its rear apron, with the front of the unit facing upwards.
2. Take precautions to avoid marking the faceplate. Placing a facial tissue over each end and grasping the faceplate through the tissue is often sufficient.
3. Place the faceplate on the front of the chassis in such a way so that the you can see the ON/OFF button coming through its prescibed cutout hole at the right hand side of
the group of control buttons. Then look downward into the rest of the holes and line up the faceplate so the buttons are directly under their respective cut-out hole.
4. Allowing the faceplate to rest on the buttons, move the faceplate gently from side to side. (about 1/8" is all the side travel usually necessary.) No further downward
pressure should be applied. Do this until the faceplate drops down onto the buttons.
5. Reinstall the 4 Allen machine screws you unfastened when you removed the faceplate. Tighten only to the point where you feel the beginning of resistance. Do not tighten
any further.
6. Set the tuner on its feet and press each button 3 or 4 times to ensure it is moving freely in its respective cut-out. If any button is not moving freely, determine on which side
of the button the faceplate is binding and adjust the faceplate very slightly to relieve it. Once it is free, check the travel of each button again to ensure they are all moving
freely.
7. Tighten the left upper screw and then the right lower screw in a similar fashion. Again check the buttons to see that they are not binding. Make adjustments as necessary to
ensure they do not bind.
8. If no buttons are binding, tighten the screws hand tight starting again with the upper right, lower left lower right and upper left.
Please note: If any button is not moving freely and sticks in the depressed position, it can possibly upset the operation of the tuner by causing the UNISET
tm
microprocessor to
lock up. Should that happen, unplug the tuner from AC power. Then adjust the buttons by first backing off the faceplate screws in the same order as explained in #8 above, and
enough to allow movement of the faceplate. Again, follow the procedure as set out in 6, 7 and 8 above. Then, when you are certain all buttons are moving freely, plug the
tuner back into AC power.
