accessories (if used) for cleanliness.
➩Remove dust and dirt (see page 68).
Installing accessories
➩Lock the Leica M525 OH4 in place and install all accessories
on the microscope so it is ready for use (see page 22).
➩Position the CAN handles as required.
➩Connect a mouth switch and/or footswitch (if used).
➩Check the camera image on the monitor and realign if
necessary.
Checking tube settings
➩Check the tube and eyepiece setting for the selected user
(see page 24).
➩Treat the eyepieces with an antifogging compound if
necessary.
Balancing
➩Balancing the Leica M525 OH4 (see page 27).
➩Press the "All Brakes" button on the CAN handle and check
the balancing.
Function check
Warning 1
Danger of fatal electrical shock.
➩The Leica M525 OH4 surgical microscope may be
connected to a grounded socket only.
➩Connect the power cable.
➩Switch on the microscope.
➩Switch on the illumination at the control unit.
Leave the illumination on for at least 5 minutes, as
otherwise luminosity will decrease rapidly.
➩Replace defective bulbs before the operation begins.
➩Test all functions on the CAN handles and on the footswitch.
➩Check the user settings on the control unit for the selected
user (see page 45).
Positioning at the OP table
➩Position the surgical microscope on the OP table as required,
and lock the footbrake (see page 35).
Sterility
➩Fit sterile components and sterile drape if used (see page 36).
Warning 2
Danger of fatal electric shock
➩Operate the system only with all equipment in its
proper position (all covers fitted, doors closed).

Installing optical accessories
Warning 3
Risk of injury through surgical microscope moving
down!
➩Complete all preparations and adjustments to the
stand before the operation.
➩Never balance or re-equip the instrument over the
field of operation.
➩Always lock the Leica M525 OH4 in position before re-
equipping it.
➩Balance the Leica M525 OH4 after re-equipping it.
➩Do not release the brakes when the instrument is in an
unbalanced state.
Locking the Leica M525 OH4 in position
The D-axis of the Leica M525 OH4 is locked in position with the
locking device.
The locking device is principally for installation and
re-equipping the Leica M525 OH4.
➩Pull out the locking buttons (1 and 2) and turn them until the
two points (arrows) are aligned above each another.
➩Move the swing arm up and down until locking device (1)
engages.
➩Move the swing arm back and forth until locking device (2)
engages.

Setting the tube
Set the interpupillary distance
Adjust the interpupillary distance to a value between 55mm and
75mm.
➩Using the adjusting wheel (1), set the interpupillary distance
such that a circular image field can be seen.
This procedure has to be performed only once for each user.
The acquired value (2) can be stored for each user on the "User
Settings" menu screen under "Tube Settings" (see page 51).

Setting the eyepiece
Determine/set the diopters for the user
The individual diopters can be adjusted continuously for each
eyepiece from +5 to -5. Only this method will ensure that the
image will stay in focus within the entire zoom range = parfocal.
The treatment microscope ensures a high degree of fatigue
resistance when the diopter setting is correct for both eyes.
A parfocal adjusted microscope ensures that the assistant´s view and monitor image will always remain
sharp.
➩Set to the minimum magnification.
➩Place a flat test object with sharp contours under the lens at
working distance.
➩Focus the microscope.
➩Set to the maximum magnification.
➩Focus the microscope.
➩Set to the minimum magnification
➩Without looking into the eyepieces, turn both eye lenses to
+5 diopters.
➩Slowly turn the eyepieces towards -5 individually for each
eye until the test object appears sharp.
➩Select the highest magnification and check the sharpness.
This procedure has to be performed only once for each
user. The acquired values can be stored for each user
on the "User Settings" menu screen under "Tube
Settings" (see page 51).
Adjusting the pupillary distance
➩Rotate the eyecups up or down until the desired distance is
set.
Eyecup
Rotary ring for adjusting
the diopters
Checking parfocality
➩Place a flat test object with sharp contours under the lens at
working distance.
➩Zoom through the whole range, observing the test object.
The image sharpness must remain constant at all
magnifications. If this is not the case, check diopter settings
of the eyepieces.
Installing documentation accessories
