LED Illumination
•
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.
•
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.
Dimmable Illumination
The dimmer switch is located on the cable near the Power
Pack Plug (Refer figure 1)
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
•
Power Packs are Lithium Ion: 11.1 Volts, 2,900 mAh.
•
The Power Pack delivers 7hrs to >20hrs “on time”
depending on illumination level.
•
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.
•
Caution: Do not expose the Power Pack to heat, fire or
mechanical shock
•
Caution: Do not open or dismantle the Power Pack.
•
Caution: Only use approved Power Packs supplied by
VorOtek.
Charger - Charging Power Pack
•
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.
•
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.
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 SpecFrame 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 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 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.
