with the projector. Move the CP550either forwards or backwards so that the test size is identical to the size of the
calibration sheet.

11. Use conditions
If you are using the device continuously, both the lens and projector could heat up, increasing the chance of
being burned.
If the device is submitted to a shock or vibrations while in use, both the mask and test might move and no
longer be projected accurately. In this case, turn the switch off and back on. The mask and test are once again
projected normally.
The remote control uses infrared rays. If another device is running at the same time on other infrared rays, the
CP550might not operate normally. Should several test projectors be used in the same eye examination room,
please contact your retailer.
If the remote control remains idle for 5 minutes, the lamp automatically turns off. To turn it back on, simply press
the LAMP button on the remote control.
11.1. General uses
5- Place the switch (7) into the "I" position in order to turn the projector on.
6- Select a test to activate lighting of the lamp. The 37 tests can be selected by pressing keys (16). Vision acuity
levels are displayed to within tenths on both sides of the mask.
7- Through use of the key (18), you can superimpose a red/green filter onto the morphoscopic acuity levels.
8- A complete row or a specific optotype may be isolated using the keys (17). Activating the "BACK" and "NEXT"
buttons allows moving this mask onto the projected test.
