Introduction
Function
Brakes The Leica M525 surgical microscope has five mechanical brakes that stop the movements of the stand and surgical microscope: • In the rotary joint (1) • In the microscope carrier (2) • At the A/B sledges of the surgical microscope (3) • Horizontal arm (4) • Horizontal arm near column (5)
Balancing system The balancing system is used to Always balance the Leica M525 surgical microscope. All movements which must be carried out during the operation require only minimal force. Two directions of movement, A and B, are balanced on the Leica M525 surgical microscope.

Introduction Tilt of the microscope carrier On the Leica M525 surgical microscope, the microscope carrier can be tilted within a range between 45° and 70°. The 70° position offers the second surgeon more headroom on the 180° dual stereo attachment. The tilt is secured in the 45° or 70° position using screws under the cover (1) (refer also to "Adjusting the tilt of the microscope carrier (45°/70°)", page 15).
Illumination The illumination of the Leica M525 surgical microscope is located in the control/illumination unit (3). It consists of two xenon lamps. If one of the xenon lamps fails, you can toggle to the other xenon lamp using the toggle switch (2).

Operation
Switching on illumination Warning 7 At a short focal length, the light source of the illumination unit may possibly be too bright for the operating physician and the patient! ➩Begin with the lower-intensity light source and slowly increase it until the operating physician has an optimally illuminated image. Always allow the illuminator to remain lit for at least five minutes, as otherwise the light output will be reduced quickly.

On the handswitch/footswitch/CAN handle: Depending on assignment (see page 24/25), the brightness of the main illumination can also be increased or decreased using two correspondingly assigned keys on the handswitch/footswitch/handle. BrightCare™ On the touch panel monitor, you can enable or disable the BrightCare™ function using the button (2). BrightCare™ is a safety function that automatically limits the maximum brightness depending on the working distance. This is because light that is too bright, in conjunction with a short working distance, can lead to burns on the patient. Explanation of light quantity: The optics of the Leica M525 F20/CT20 surgical microscope have a variable working distance of between 207 and 470 mm. The system is designed in such a way that it delivers sufficient light to produce a bright image even at a long working distance of 470 mm. According to the formula Ev=Iv/d2, the light quantity continually increases by 510 % when the working distance is changed from 470 to 207 mm. (Ev = light intensity, Iv = brightness, d = distance from the light source) This means that less light is required to work with the microscope at a shorter distance than at a greater distance. As a result, it is practical to begin with the light source at a lower intensity and then increase it until you have achieved an optimally illuminated image. When the microscope is shipped from the factory, the "BrightCare™" safety function is activated for all users.
➩Switch on main illuminator at the switch (3). Adjusting the brightness Brightness can be increased or decreased using the touch panel monitor, a handswitch/footswitch or a CAN handle. On the touch panel monitor: ➩Press the "+" or "–" button on the bar for adjusting the (1) brightness of the illumination. or ➩Press the brightness adjustment bar (1) directly. The brightness of the active main illuminator changes.
Explanation of heat development: Heat from invisible light (above 700 nm) is filtered out of the light of the xenon light source used. Nevertheless, white light also always develops heat. An excessive amount of white light can lead to overheating of tissue and metal objects. As a result, it is practical to begin with the light source at a lower intensity and then increase it until you have achieved an optimally illuminated image.
Clicking the "+" or "–" key changes the brightness value in increments of one. Holding down the mouse button with your finger changes the value in increments of five. The start value can be saved individually for each user. Even when switched off, the brightness setting can still be read. However, the brightness display bar appears darker.
