Engage the highest magnification.Bring the test object into focus.Engage the lowest magnification.
3. Adjust the dioptric settings
Adjust the dioptric settings for each eye in turn (2), so that
the image is seen in sharp focus.
Engage the highest magnification.Refocus using motor-driven focusing.Engage the lowest magnification.Inspect the dioptric settings, readjusting them if necessary
so that both images are sharp.
4. Inspect the parfocality
Zoom through the whole range, observing the test object.
The image sharpness must remain constant at all magnifica­tions. If it does not, then repeat points 2 to 4 of this proce­dure.

amateur radio, AM and FM broadcast and TV broadcast cannot be predicted theoretically with accuracy. To assess the elec­tromagnetic environment due to fixed RF transmitters, an electromagnetic site survey should be considered. If the measured field strength in the location in which the Leica M501 surgical microscope is used exceeds the applicable RF compliance level above, the Leica M501 should be observed to verify normal operation. If abnormal performance is observed, additional measures may be necessary, such as reorienting or relocating the Leica M501.
b Over the frequency range 150kHz to 80MHz, field strengths should be less than 3V/m.

Table 206 from EN 60601-1-2:2001
Recommended separation distances between portable and mobile RF telecommunications equipment and the Leica M501 surgical microscope
The Leica M501 surgical microscope is intended for use in an electromagnetic environment in which radiated RF disturbances are controlled. The customer or user of the Leica M501 surgical microscope can help prevent electromagnetic interference by maintaining a minimum distance between portable and mobile RF communication equipment (transmitters) and the Leica M501 as recommended below, according to the maximum output power of the communications equipment.
Separation distance according to frequency of transmitter in m
Rated maximum output 150 kHz to 2.5 GHz power of transmitter W
d = 2.4 P in m
0.01 0.24
0.1 0.8
1 2.4
10 8.0
100 24.0
For transmitters rated at a maximum output power not listed above, the recommended separation distance d in meters (m) can be estimated using the equation applicable to the frequency of the transmitter, where P is the maximum output powerrating of the transmitter in watts (W) according to the transmitter manufacturer.
Note 1: These guidelines may not apply in all situations. Electromagnetic propagation is affected by
absorption and reflection from structures, objects and people.
Warning message:
Using accessories or cables other than those listed here or those permitted by the manufacturer of the Leica M501 surgical microscope may result in increased electromagnetic emissions or decreased immunity.
Warning message:
The Leica M501 surgical microscope may not be used while positioned directly next to other instruments. If it is necessary to operate it in the vicinity of other instruments, the instrument should be monitored to ensure that it functions properly in this arrangement.
