LED Illumination
•
Caution: Hot surface. Avoid direct skin contact
with aluminium heat sink during extended periods
of use.
•
Caution: Do not look directly into the LED Light.
•
High efficiency LED (Light Emitting Diodes) are
rated at 50,000 hours operating life.
•
5,700 Degrees Kelvin Colour Temperature
(Daylight).
•
Colour Rendering Index: CRI 75.
Dimmable Illumination
The dimmer switch is located on the wiring lead
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.
Power Pack
•

fire or mechanical shock
•
Caution: Do not open or dismantle the Power
Pack.
•
Caution: Only use approved Power Packs supplied
by VorOtek.
•
Power Packs are Lithium Ion: 11.1 Volts, 2,900
mAh.
•
The Power Pack provides 10hrs of “on time”.
•
The Power Pack features short circuit protection
and charging control circuitry.
•
Two position switch - ON/OFF.
•
Designed to be worn in the breast pocket or to be
clipped to a belt. It can also be clipped to the back
of a surgical gown.
Charger - Charging power pack
•
Caution: Use the supplied 12.6V Charger only.
•
Caution: Do not attempt to operate the charger if
the cord and/or plug appear to be damaged.
•
Caution: Do not use charger in the patient
vicinity.
•
Connect Power Pack to Charger.
•
The Power Pack can be charged in either the ON
or OFF position.
•
RED INDICATORS – Charging (takes up to 5
hours).
•
GREEN INDICATORS – 100% Charged.
•
Charging is best done overnight, frequently and
before the power pack runs flat.
Set Up
Interpupillary Distance (IPD) Adjustment –
Loupes
The IPD can be adjusted by slightly loosening the
screw caps so that the loupe pods can slide left and
right in the slots of the bracket.
•
Slide loupe pods to suit your IPD.
•
Once adjusted, tighten the screw caps finger
tight so that the loupe pods have zero
movement.
Tilt Adjustment - HeadBand Model
If the loupes are tilted, adjust the HeadBand
position until level.
Tilt Adjustment - SpecFrame Model
If the loupes are tilted, adjust the nose pads &
temple tips/arms on the spectacle frame until
level.
Height Adjustment - HeadBand Model
The height of the loupes / illumination system is
adjusted by moving the HeadBand up or down on
the forehead.
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.
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 loupes and below the light spot)
The loupes 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 the angle of
declination and forward positioning of the loupes /
illumination system.
•
The loupes must be positioned as close to the eyes
as possible i.e. almost touching the nose or
spectacles.
•
If the loupes are not in use (rotated up) then the
illumination can be angled further downwards.
SpecFrame Toggle
The toggle on wiring lead should be used for all
lengthy procedures, e.g. Operating.
•
To prevent SpecFrame sliding down the nose
when head is tilted down.
•
To take pressure off the nose.
Working with Corrective Lenses
Corrective Lenses can be fitted to the SpecFrame of
the L Scope by an Optometrist.
•
There is no need to unscrew the illumination
system or dismantle the L 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, the working
distance becomes closer.
Bifocal Lenses
•
Can be fitted effectively, so long as the loupes sit
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 loupes 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.
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, new nose pads
and bent frames.
•
For SpecFrame replacement contact VorOtek.
For all other questions contact VorOtek.
