11. Secure the assembly firmly using the four socket head cap screws. Carefully lean the whole assembly back down on to the floor (at least 2 people required). 12. Identify and remove the arm bearing mounts from the box. The ‘TOP’ arm bearing mount has a plain bearing in the large hole, the ‘BOTTOM’ arm bearing mount has a flanged bearing in the large hole. 13. Remove the pantograph arm assembly from the crate. Remove the tape which holds the friction washers in place on the top exposed shaft at the end of the pantograph arm, but make sure the friction washers stay in place. The TOP side of the pantograph arm may be identified as the plain side; the BOTTOM side features the sliding knob safety stop assembly. 14. Place the arm bearing mounts in their correct orientation over the ends of the shaft on the pantograph arm. Note that the BOTTOM arm bearing mount must be supported by hand from underneath to prevent it dropping down.

With the arm bearing mounts in place slide the pantograph arm horizontally in to the end of the horizontal arm assembly. Note that some shuffling movement will help to move the arm in to place. When the arm bearing mounts are flush against the horizontal arm, insert the 8 M6 x 20 countersunk socket screws and tighten them alternately using the 4 mm socket key. If the holes do not line up exactly, rotate the pantograph arm about its axis so that the weight of the arm helps to align the holes. 16. Identify and remove the elbow lock knob from the box. Screw the knob in underneath the end of the horizontal arm. If the knob does not run freely in the hole, disassemble the pantograph arm from the horizontal arm and check again that the TOP and BOTTOM arm bearing mounts are in their correct orientation. 15.

17. Identify and remove the XY unit from the box. Remove the upper bearing and knob assembly from the XY unit by unscrewing the knob. Make sure that the washer stack remains inside the counter bore in the top bearing. 18. This important safety step is critical! Lower the pantograph arm so that the shaft of the XY unit may be inserted from underneath the conical bearing surface at the free end of the pantograph arm. Support the XY unit from underneath and hold it firm against the bearing surface. Tighten the 3 M6 x 12 safety screws (which are already in place) located at the end of the arm using the 5 mm socket key. While holding the XY unit, check that the safety screws are functioning by demonstrating that the XY unit will not drop to the floor when support from underneath is removed. 19. Place the upper bearing over the shaft of the XY unit from above the pantograph arm, ensuring that the slot locates on the transverse pin in the mounting shaft, and that the friction washers are in place. Then screw the knob up on the shaft to set the friction for rotational movement of the XY unit. Rotate the XY unit until the front panel (identified by the Scan Optics label) faces out in line with the pantograph arm.

22. With the head assembly and bracket placed securely on a table or bench, manoeuvre the floor stand towards the table so that when the pantograph arm is lowered, the front of the XY unit faces towards the location of the microscope eyepieces. Lower the pantograph arm down so that the protrusion underneath the XY unit aligns with the shape of the suspension bracket, and that the 4 tapped holes on the underneath of the XY unit align with the 4 clearance holes on the suspension bracket. Fix the suspension bracket to the XY unit by screwing in the four M6 x 30 socket head cap screws from underneath. Tighten the screws evenly using the 5 mm socket key so that there is an equal gap on either side of the suspension bracket. Check that the head assembly can now be safely lifted by lifting the entire pantograph arm.

10. Switch the microscope on from the main panel. Depress button 1 (its green LED will go OFF) then button 2 (its green LED will go ON), and set the light intensity as desired. Switch the monitor on. 11. Focus the main microscope at the preferred magnification. If the microscope is typically used with a range of magnifications, focus the microscope at the highest magnification (smallest field). 12. Loosen the two lower grubscrews below the camera. Observe the image on the monitor, and focus the camera by rotating the lower ring. Retighten the lower grubscrews when the camera is focussed.
13. Check the orientation of the image by moving an object across the field, to see if left/right and up/down on the monitor correspond with left/right and up/down as observed through the main microscope. If it does not, loosen the upper grubscrew and rotate the upper ring until the orientation is correct. This should correspond with the upside-down ‘CE’ mark on the camera facing the observer using the main microscope. When the orientation is correct, re-tighten the upper grubscrew.

POWER SUPPLY
The power supply controls some of the most important functions of the SO5800W 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 1 once (the LED indicator will turn off) to allow microscope functions to be activated. Press the lamp button 2 once (the LED indicator will come on) to turn the lamp on. The lamp intensity may be controlled in five discrete steps by depressing the ! or " buttons 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 XY 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 XY 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 XY 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. Issue number 1.0

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 connector on the top face of the horizontal arm provides low voltage power for XY, zoom and focus motors, as well as the lamp and its fan. 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. The knob marked ‘ELBOW FRICTION’ provided beneath the end of the horizontal arm 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. Issue number 1.0

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.
The pantograph can rotate some 270° relative to the horizontal arm and is locked using the knob located under the end of the horizontal arm (elbow lock). Note that if both elbow friction and shoulder locks are applied and a side force is applied to the end of the pantograph arm, the elbow lock will give way if sufficient force is applied. If a fixed angle between the horizontal and pantograph arm is required, the elbow friction will work best if the shoulder lock is not applied. To lock the arm in a particular vertical position, simply rotate the ‘ARM LOCK’ knob clock-wise. To lock the rotational movement of the XY unit and microscope head below the end of the pantograph arm, rotate the ‘ROTATION LOCK’ knob clock-wise. Issue number 1.0

GAS SPRING ADJUSTMENT
A gas spring inside the pantograph arm provides lifting force, which is able to support the weight of the XY unit and microscope head at the end of the arm. By moving the end position of the gas spring, the amount of lifting force can be varied depending on the preference of the user or to suit the weight of additional accessories which may be placed on the microscope head assembly. By rotating the knob clockwise, the end of the gas spring is lowered which increases the amount of vertical force. Similarly, anticlockwise movement will increase the end position height and reduce the amount of vertical force. The factory setting should mean the arm is almost perfectly balanced in any position when the standard accessories are placed on the microscope head. By variation of the gas spring position, the pantograph arm may also be set to always rise upwards, or to fall when released depending on individual preference.

SAFETY STOP
The SO-5800W is fitted with a safety stop mechanism that enables the user to pre-set a particular height below which the pantograph arm will not move. Where the knob position is set closest to the horizontal arm end, there is no impediment to movement. When the knob is locked closest to the microscope head end, there will be almost no movement allowed in the pantograph arm below its rest (UP) position. Locations in between will allow a limited rage of movement. Note that the knob MUST be locked in position for the safety mechanism to take effect. To use, unscrew the knob, then press the shaft in and move the slider to the desired position. To lock, screw the knob tight again.

XY UNIT
The XY unit allows the user to move the microscope head laterally, by means of the joystick on the foot control. To move the head to the right, simply move the joystick to the right, to move the head forward, move the joystick forward, and so on. Movement combinations may also be achieved by moving the joystick diagonally. Speed of XY movement is controlled using the knob on the main power supply panel. The XY unit also acts as an interface for distributing power to the microscope head and video camera. These connections are labelled on the rear panel of the XY unit.
A return to centre (RTC) function built in to the XY unit allows the user to return the microscope head to a home position, centred on the middle of the range of movement. To activate this function, simply press the button on the front panel of the XY unit. The RTC function will and the LED above the window will flash intermittently while the unit is returning to centre. This LED will also provide a continuous light when the joystick on the foot control is used to drive the head in normal fashion. Issue number 1.0
