Set Up
Converged Binocular Optics Alignment
Converged binocular optics with 2 dioptre magnification.
Without this, binocular vision in narrow cavities (e.g. ears
and noses) is not possible.
The best guide to precise set up is to look into a mirror
(with light switched off!) and look back through the
converged binocular optics at the position of your eyes.
You should be able to see both of your pupils clearly.
(Refer Figure 1)
Interpupillary Distance (IPD)
The IPD can be adjusted by sliding the tabs located at
each end of the converged binocular optics. Slide the
tabs to move the mirrors to match your eye width (IPD).
(Refer illustration above)
Tilt Adjustment –SpecFrame Model
If the converged binocular optics are tilted, adjust the
nose pads & temple tips/arms on SpecFrame until level.
Tilt Adjustment –HeadBand Model
If the converged binocular optics are tilted, adjust the
HeadBand position until level.
Height Adjustment -SpecFrame Model
The height of the converged binocular / illumination
system is adjusted by moving the system up or down on
the SpecFrame bracket:
•Loosen the screw that connects the illumination
system to the SpecFrame bracket by 1 turn and adjust
the height.
•Do not leave screw loose, always re-tighten.
Height Adjustment -HeadBand Model
The height of the converged binocular / illumination
system is adjusted by moving the HeadBand up or down
on the forehead.
Illumination Adjustment
If the light spot seems too high, the height adjustment
will be too low. (i.e. the user is looking down through the
converged binocular optics and below the light spot) The
converged binocular optics will need to be positioned
higher to correct.
If the light seems too low the reverse will apply. See
‘Height Adjustment’.
HeadBand Bracket Adjustment
The HeadBand mounting bracket has 2 adjustable links
allowing separate adjustment of viewing angle and
forward positioning of the converged binocular /
illumination system:
•The converged binocular optics must be positioned 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.
SpecFrame Toggle
The toggle on the cable lead should be used for all lengthy
procedures, e.g. Operating to:
•Prevent SpecFrame sliding down the nose when head is
tilted down.
•Take pressure off the nose.
Working with Corrective Lenses
Corrective Lenses can be fitted to the SpecFrame of the V
Scope by an Optometrist.
•There is no need to unscrew the illumination system or
dismantle the V Scope in any way, other than the frame
screws for the lenses.
Reading Lenses (used for close work)
•Should be fitted to the SpecFrame Model.
•The HeadBand 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 reading section must be larger (i.e.
lower two thirds) and the distance section must be
smaller (i.e. upper one third only).
•The height of 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.
Dimmable Illumination
The dimmer switch is located on the cable near the Power
Pack Plug (Refer figure 2)
The dimmer function provides 8 levels of illumination
with “H” being the highest .
Dimming: Press the “+” or “-” button on the dimmer
switch to select the preferred level of illumination.
ON/OFF function: Click & hold either button on the
dimmer switch for 2 seconds to turn illumination “on” or
“off” at the selected level.
Troubleshooting
LED illumination cuts out and resets
repeatedly
•The LED illumination does not fade, but the protective
circuit breaker keeps switching off (and resetting) when
the Power Pack requires recharging. See section on
‘Charger’.
•LED’s rarely need replacing, but if this is necessary it
must be done by VorOtek.
Power Pack will not charge
•See section on ‘Charger’.
SpecFrame damage
•Most problems can be dealt with by an optometrist e.g.
missing screws, lenses, new nose pads and bent frames.
•For SpecFrame replacement contact VorOtek.
