1. Good indirect lighting is needed e g bathroom or vanity mirror ETE Double image lt This is a short term problem for some users Eye exercises such as looking at a on a plain back ground with one eye other eye then both eyes and at different distances will usually help Also recheck set up for accurate positioning in front of the eyes Altered depth perception The converged binocular optics creates this effect After a few days use it is no longer noticed Toggle on wiring leash lt This is often worth using To prevent sliding down the nose For all lengthy procedures e g operating To take pressure off the nose When gaze is downward Working with Corrective Lenses Reading lenses used for close work Should be fitted to the SpecFrame of the O Scope The HeadBand O Scope model should be used over the individuals own corrective spectacles When reading lenses are installed and used the working distance becomes closer If the working distance is not close enough then an extra 0 5 or 1 0 dioptres in the corrective lens should be tried The opposite may be encountered especially for users with intrinsic short sight Bifocal lenses Can be fitted effectively so long as the converged binocular optics sits in front of the reading section and below the distance section To achieve this the distance section must be smaller i e upper one third only and the reading section larger i e lower2. end Wrap Blu Tack around tip of speculum It should be possible to achieve a complete seal in every ear For all other problems contact VOROTEK Warranty Scopes 3 year for any component defect or manufacturing failure Battery Pack 18 months for any component defect or manufacturing failure Warranty does not cover abuse misuse or transit damage Please contact VOROTEK to discuss problems or faults before sending for repairs LA ZLSON OA
3. two thirds The nose bridge may need to be adjusted to sit the SpecFrame higher on the face This extra frame height allows lower positioning of the converged binoculars so that they are in front of the reading section Alternative nose bridges are available from most optometrists Multifocal lenses Are best avoided because it is difficult to achieve sharp focus Lens fitment Please advise the optometrist to rotate the converged binocular optics upwards when fitting lenses There is no need to unscrew the converged binocular illumination system or dismantle the scope in any way other than the frame mounting screws for the lenses Troubleshooting Illumination cuts off See section on Indication That Battery Pack must be charged Battery Pack will not charge See section on Battery Pack and Charger SpecFrame damage Most problems can be dealt with by an optometrist e g missing screws new nose pads and bent frames For SpecFrame replacement contact VOROTEK Working distance Not close enough or too close see section on corrective lenses Pneumatic Otoscope reflecting light back into O Scope users eyes Change angle of view through the puffer lens Suggest always rotating puffer so the tubing is directed forward towards the nose of patient Light from a window can also cause reflection Pneumatic Otoscope system has excessive air leak Use bigger speculum Insert deeper i e until canal hairs
4. Bracket adjustment The HeadBand mounting bracket has 2 adjustable links The shorter upper link mainly controls the forward distance of the converged binocular illumination system The 2 link system allows separate adjustment of viewing angle and forward positioning of the converged binocular illumination system The converged binocular optics must be adjusted as close to the eyes as possible i e almost touching the nose or spectacles For ENT use the viewing direction should be almost horizontal If the converged binocular optics are not in use rotated up then the illumination can be angled further downwards Height adjustment The height of the converged binocular illumination system is adjusted by moving the HeadBand up or down on the forehead If the converged binocular illumination system is tilted the HeadBand position will need adjustment NOTE If the illumination spot seems too high the height adjustment is likely to be low so that the user is looking down through the converged binocular optics and below the illumination spot If the light seems too low the reverse will apply HeadBand amp SpecFrame Model Mirror check Should The best guide to precise adjustment is to look into a mirror with light switched off and look back through the converged binocular optics at the position of your own eyes You should be able to see both of your pupils clearly refer illustration
5. O SCOPE INTEGRATED CONVERGED BINOCULARS amp LED ILLUMINATION VOROTEK T 61 3 5251 3229 E office vorotek com au www vorotek com au Features Specifications Set up 8 Troubleshooting Converged Binocular Optics Converged binocular optics with 2 dioptre magnification Converged binocular optics are also a feature of operating microscopes Without this binocular vision in narrow cavities e g ears and noses is not possible LED Illumination Light emitting diodes LED are a solid state device with an average life of gt 35 000 hours They rarely need replacing but if this is necessary it must be done by VOROTEK The illumination colour is daylight and does not vary with the age of the LED or the level of charge of the battery pack Illumination uniformity and quality is much better than with filament lamps Brightness now compares with operating room headlights Battery Pack and Charger Direct Mains Power Supply Specifications and features Batteries are Lithium lon 7 4 Volts 2 000mAh This provides 5 hours of on time at maximum level of illumination Optional 10 hour Battery available Memory effect for these batteries is negligible The Battery Pack features short circuit protection and charging control circuitry Use only the supplied Charger otherwise warranty will be void For operations lasting several hours the Direct Mains Power Supply is often a better option see Direct Mains Power Supply For num
6. daptor plug I Set up of O Scope Speck rame Model chosen by most individual users Height adjustment The height of the converged binocular illumination system is adjusted by moving the system up or down on the Spec Frame bracket Loosen the screw that connects the converged binocular illumination system to the SpecFrame 1 turn and adjust Do not leave screw loose always re tighten NOTE If the light spot seems too high the height adjustment is likely to be low so that the user is looking down through the converged binocular optics and below the light spot If the light seems too low the reverse will apply IPD interpupillary distance The mirrors in the converged binocular optics are laser aligned and fixed in place to suit a specific IPD This means that no adjustment is ever required and the converged binocular optics are more robust Your IPD measurement for distance vision can be obtained from an optometrist Converged binocular optics with fixed IPD can be used in a range of 2mm e g 63mm can be used for 61 to 65 IPD HeadBand Model The HeadBand version requires more care to keep the converged binocular illumination system in the optimal position therefore individual owners mostly choose the SpecFrame model The big advantage of the of the HeadBand model are that lt can be worn over any spectacles Ithas an adjustable IPD It can be adjusted to suit any head
7. erous short procedures the Battery Pack is very convenient It is designed for use on left side of belt or in shirt pocket of scrubs If it is worn in the breast pocket the switch can be used by the operator through the operating gown An alternative is to clip the Battery Pack to the back of the gown Switch on Battery Pack Switch on Battery Pack has three positions which are labelled ON OFF and CHARGE Indication that Battery Pack must be charged LED illumination cuts out and resets repeatedly NOTE LED illumination does not fade but the protective circuit breaker keeps switching off and resetting NOTE Charging is best done overnight frequently and before the Battery Pack runs flat Battery Pack charging Battery Pack indicator Set switch on the Battery Pack to charge position RED CONSTANT Charging takes up to 8 hours GREEN 90 plus charged but still trickle charging When charging reaches 100 trickling stops and indicator reverts to red flashing RED FLASHING Fully charged It will also flash red if incorrectly connected i e Battery Pack switch not in the charge position or charger not connected to mains Direct Mains Power Supply To connect the O Scope to the Direct Mains Power Supply the adaptor plug must be used The adaptor plug is fixed to the Charger Direct Mains Power Supply lead see diagram below NOTE Battery Pack cannot be connected Plug into mains power To scope ey gt A
