Do not press the LEARN button (this will enter you

into learn mode, which you must not play with). If you

accidentally press this button, you will see the word

“EXIT “ flashing. Press the LEARN button again to

Changing filters

Use the motorized fluorescent filter cube changer on

the microscope control panel:

Red light shows current filter cube selection

The filter cube turret contains three filters plus an

empty slot

GFP : cube for green fluorochromes

RED : cube for red fluorochromes

CFP/ : cube for far red fluorochromes

or cube for CFP (see Paula for details)

SCAN : empty slot

Notes:

The cube in the CFP/ position is normally the far

red cube, suitable for fluorochromes such as

TOTO-3 and Cy5

The SCAN position is used for confocal imaging

and for transmitted light observation through the

eyepieces
