Smartphone holder
Open the flexible holder and put your smart-
phone in it. Close the cradle and make sure your
phone is properly seated. The camera must be
positioned exactly above the eyepiece. Open
the locking clip on the back of the holder and
fit the eyepiece view exactly onto your smart-
phone camera. Now retighten the locking clip
and attach the smartphone holder to the eye-
piece of your microscope. Now start the cam-
era app. If the image is not yet centered on
your display, loosen the locking clip slightly
and readjust. It may be necessary to use the
zoom function to fill the image on the display.
A slight shading at the edges is possible. Re-
move the smartphone from the cradle after use!
NOTE:
Make sure that the smartphone cannot slip off
the cradle. Bresser GmbH accepts no liability
for damage caused by a dropped smartphone!
