To call up a sequence:
1) Press button
1
or
2
, according to the desired sequence.
2) The
NEXT
button advances to the next test in the sequence; the
BACK
button goes back to the pre-
vious test.
3) Press any key to exit the sequence.
To change a test in a previously-memorized sequence:
1) With the projector on and in standby, hold down program button for 5 seconds until a beep sounds
to signal entry into programming mode.
2) Press
NEXT
to advance to the test to be substituted.
3) Press the button for the new test to be entered.
4) Press the
NEXT
button to advance to the end of the sequence. You will see an empty test circle.
5) Hold down program button
1
or
2
for 5 seconds until a beep sounds to signal that the projector has
exited the programming mode and entered standby.
To interrupt a sequence:
1) With the projector on and in standby, hold down program button
1
or
2
for 5 seconds, according to
the sequence to be modified.
2) Press the
NEXT
button to advance to the test at which the sequence is to be interrupted.
3) Hold down program button
1
or
2
for 5 seconds until a beep sounds to signal that the projector has
exited the programming mode.
Projection Distance
The patient and the projector must be at the same distance from the projection surface, except in the
case of the CP 2033 Zoom projector. The angle of vision, like measurement of visual acuity, is not
influenced by this fact and the visus attributed each time will be valid for all distances. In order not to
falsify the refraction value, the projection distance must fall between a minimum of 2.9 m and a maxi-
mum of 6.1 m.
With the Zoom projector (CP 2033) it is not necessary to align the projector and the patient with respect
to the projection surface (tolerance is ± 1m), but in this case the visus is dependent on the projection
distance and verification on the projected enlargement will thus be required.
Projection with Mirrors
In rooms in which it is impossible to attain the minimum projection distance (2.9 m), the distance can
be doubled by using mirrors.
