# " If the microscope is to be stored or transported, it is recommended that the original packaging be re-used for this purpose. If possible, re-pack each assembly in its original plastic bag. The best storage location is a low humidity, dust-free environment, such as an air-conditioned room.
" * The first step in assembling the binocular assistant microscope is to determine from which side of the main microscope the assistant will be viewing. *
"
When the assistant will view from the left hand side of the main microscope, the microscope should be configured as shown below. Attach the head assembly to the arm assembly by inserting the screw in the microscope mount threaded hole, and tightening the microscope lock knob until the head is secure.

To swap the microscope arm from the LHS to RHS configuration, follow the instructions below. To swap from RHS to LHS configuration, simply follow the instructions in reverse. 1. Loosen the angle lock knob.
2.
Move the microscope mount sideways so that it rests against the angle lock knob again. This will disengage the safety stops which prevent the microscope from falling below a particular angle in the LHS configuration, and allow the mounting arm to be rotated through 180 degrees.
3. Rotate the mounting arm so that the arm assembly looks like the picture below.
4. Slide the microscope mount back again to engage the safety mechanism
5. Rotate the microscope mount until it looks like the picture below
6. Tighten the angle lock knob again to secure the assembly. The arm assembly is now in RHS mounting configuration.

Depending on the configuration of the main microscope, the viewing position of the assistant microscope can be adjusted to enhance the viewing angle from 25 degrees to 20 degrees. This can be achieved on both sides of SO-161R, SO-111W and SO-111WF microscopes, and on the left hand side of SO-5600W, SO-5100W, SO-5000W and SO5800 microscopes. To adjust the position, remove the socket head cap screw from the side of the arm assembly and slide the mounting arm along the housing. Reinsert the screw and tighten it when the hole in the mounting arm lines up with the hole in the housing.

(
SO-5800, SO-5600W, SO-5100W and SO-5000W microscopes come pre-fitted with accessory mounts on the sides of the main microscope assembly. Other microscopes must be fitted with a mounting kit before attaching the SO-1440 binocular assistant microscope to the main microscope assembly. " *

The first step is to determine from which side of the main microscope the assistant will be viewing. The mounting kit may be fitted on either side of the main microscope. To illustrate fitting the mounting kit the RHS of a SO-111WF microscope is depicted, but the same principles apply to other microscope types. 1. Locate the accessory mounting plate on the side of the main microscope head assembly. 2. Attach the mounting block to the accessory mounting plate using the four M5x10 socket head cap screws and the 4mm socket key provided. 3. Insert the accessory locking pin in the hole in the top of the mounting block for safe keeping. This pin is used to lock the binocular assistant microscope mounting arm in place when inserted.
"
*
To fit the assistant microscope to the main microscope, simply lift up the accessory locking pin and insert the mounting arm into the mounting block. Replace the accessory locking pin in the hole ensuring that it engages firmly in the hole in the mounting arm to lock it in place. * "

To focus the SO-1440 binocular assistant microscope, first focus the main microscope according to the instructions in its manual. It may be helpful to focus on a target such as the one printed on this page.
1. Hold the binocular assistant microscope head assembly with one hand and loosen the angle lock knob slightly. Look through the eyepieces of the binocular assistant microscope and manoeuvre the microscope until the target is centred in the vertical plane. 2. Tighten the angle lock knob and focus the assistant microscope using its own focus knob(s) while looking through the RHS eyepiece only with the right eye. 3. Re-check the vertical alignment and adjust the position of the binocular assistant microscope head if necessary after loosening the angle lock knob. Re-tighten the angle lock knob when vertical alignment is achieved. 4. Look through the LHS (adjustable) eyepiece with the left eye and rotate the collar until the left eye is in focus. 5. Adjust the pupillary distance (PD) of the assistant microscope to a comfortable setting by rotating the prism housings apart or together as required. Note that the prism housings are not geared together and need to be adjusted to a symmetrical position manually.
6. When this procedure is complete the microscope should be centred on the vertical plane of the target and focussed on the centre of the target, although there may be some left-right displacement. 7. To correct for left-right displacement, loosen the microscope lock knob and swivel the microscope head assembly left or right slightly until the centre of the target is in the centre of the view. Tighten the microscope lock knob to secure the assembly. 8. The assistant microscope should stay focussed so long as the image through the main microscope is focussed.

Sterilisable covers can be fitted to the manual focus knobs of the assistant microscope and will also fit on the angle lock knob and microscope lock knob if required. Additional sterilisable covers may be purchased from Scan Optics in the event of loss or damage. The covers may be sterilised by: boiling autoclaving chemical sterilisation gas sterilisation. Note that national authorities may require the use of specific sterilisation or disinfection methods.
"* "
Regular inspection and cleaning of the microscope will ensure reliable operation. In particular, check the objective lens and eyepieces for cleanliness each time the instrument is used. Surface dust should be removed with a clean, soft brush. Fingerprints, irrigation solution residue and grease may be removed by lightly wiping with a cotton cloth or lens tissue moistened with a mixture of 70% ether and 30% absolute alcohol (either ethanol or methanol). If this mixture is unavailable, pure alcohol can be substituted. Do not use acetone as it may damage the surface coatings of the lenses. "
While not in use, the SO-1440 binocular assistant microscope should be stored carefully, with the eyepiece caps in place to prevent accidental damage. If the microscope is to be stored or transported, it is recommended that the original packaging be re-used for this purpose. If possible, re-pack each assembly in its original plastic bag. The best storage location is a low humidity, dust-free environment, such as an air-conditioned room. !
The SO-1440 binocular assistant microscope is fitted with anti-mould protection which is effective for approximately three years. However, the effective life of this protection will depend on environmental factors such as the temperature and humidity of the place where the microscope is stored. Regular inspection of the microscope will help early identification of mould and alert the user of the need to replace the anti-mould protection. To replace the anti-mould protection pellet: 1. Slightly loosen the grubscrew at the top of the objective assembly. 2. Remove the four M3x20 socket head cap screws from the objective assembly. 3. Remove the existing antimould pellet. 4. Remove the adhesive backing from the new pellet and secure it in place. Note that where the pellets are supplied in pairs, scissors can be used to separate the pair and trim the corners of the single pellet. 5. Replace the objective assembly by securing the M3x 20 socket head cap screws again.
