INTRODUCTION
Please read the following information carefully before using the Scan Optics
SO-5800 ophthalmic microscope. Scan Optics is responsible for the safety,
reliability and performance of the equipment only if it is used in accordance
with these instructions.
This microscope is designed for use by a certified practitioner, for magnified
observation of patients, and for use in an operating theatre as an observation aid
during surgery.
Environmental storage and packing conditions of 60-95% relative humidity and
10-40°C are recommended for this product.
No parts or accessories supplied with this microscope are supplied in a sterile
condition.
Apart from those instructions within this manual, there are no user-serviceable
parts in this microscope. Scan Optics will retain the discretion to advise
whether any repairs may be taken out by external qualified technical personnel,
or whether part(s) of the microscope must be returned to the manufacturer’s

FLOOR STAND
The floor stand provides a stable platform for the microscope, enabling it to be
moved freely and also to be locked in to position.
To move the floor stand, first fold the pantograph arms carefully back against
the horizontal arm, and lock the arms to minimise the risk of accidental damage
to the microscope head. Depress the latches marked on each of the legs in the
diagram above to unlock the wheels. Then grip the handles on the side of the
main pillar and move the floor stand as desired. To lock the floor stand depress
the large black knobs as shown on the diagram. Note that no twisting of the
knobs is necessary. To unlock the floor stand, simply depress the latches on
each leg and the locks will spring up.

PILLAR
The pillar contains two panels, a lower panel for connecting to mains power and
the foot control, and a power supply panel for controlling microscope functions.
LOWER PANEL
The foot control and IEC mains plug should be connected as shown in the
diagram below. Note that the retaining clip should be used to avoid accidental
removal of the mains plug.
When attaching the foot control cable, align the square feature on the plug with
the recess on the panel socket. Insert the plug in the socket and rotate the
housing clock-wise to secure the connection.

POWER SUPPLY
The power supply controls some of the most important functions of the
SO-5800 microscope.
To switch the microscope on, depress the mains switch. An indicator on the
switch will glow, indicating that power is available. Press the standby button
jonce (the LED indicator will turn off) to allow microscope functions to be
activated. Press the lamp button konce (the LED indicator will come on) to
turn the lamp on. The lamp intensity may be controlled in five discrete steps by
depressing the por qbuttons as appropriate, while the intensity setting will be
displayed by the indicator LEDs. If the standby button is depressed (its LED

indicator will turn on) the lamp will switch off, when the button is depressed
again, the lamp will return to its previous intensity setting.
Speed of X-Y movement and focus/zoom movement may be controlled by
rotating the control knobs clock-wise to increase speed or counter-clock-wise to
decrease speed. Note that at extremely low speed settings, movement may be
imperceptibly slow or completely absent.
The X-Y indicator will light up constantly when the foot control is used to
position the microscope laterally. The indicator will flash when the return to
centre function has been activated from the X-Y unit.
The Focus/zoom indicator will light up constantly when the foot control is used
to focus the microscope up or down, or to zoom the microscope in or out.

HORIZONTAL ARM
The horizontal arm rotates about the top of the pillar and provides a connection
interface for the main microscope power cable. Stops are fitted to prevent the
arm rotating continuously around the pillar; this prevents the internal cabling
from twisting. The range of movement allowed is 300°.
The knob at the top of the pillar labelled ‘SHOULDER LOCK’ enables the
horizontal arm to be fixed in position. To lock the arm, rotate the knob in
clock-wise fashion.
To connect the microscope power cable to the socket marked ‘MICROSCOPE
POWER OUT’ align the square feature on the plug with the recess on the panel
socket. Insert the plug in the socket and rotate the housing clock-wise to secure
the connection.
A knob marked ‘ELBOW FRICTION’ is provided beneath the end of the
horizontal arm and allows friction to be applied to the swivel joint between the
pantograph arm and the horizontal arm. To increase friction, rotate the knob in
clock-wise fashion when viewed from beneath the horizontal arm.

PANTOGRAPH ARM
The pantograph arm rotates about the end of the horizontal arm and also
provides a means for manually raising and lowering the microscope head. The
pantograph arm includes features that enable the user to achieve the required
type and feel of microscope movement.
To lock the arm in a particular vertical position, simply rotate the ‘ARM
LOCK’ knob clock-wise. To lock the rotational movement of the X-Y unit and
microscope head below the end of the pantograph arm, rotate the ‘ROTATION
LOCK’ knob clock-wise.
