Cleaning And Maintenance; Technical Specification - HEINE OMEGA 500 Instrucciones De Manejo

Changing the bulb:
• First allow the instrument to cool down.
• Disconnect the instrument from the power source.
• Unscrew the control (2) so that the optics unit (3) is free to move.
• Slide the bulb cover (12) upwards. Do not pull on the cord.
• Swivel the optics unit (3) to enable the bulb (13) to be pulled out of the
bulbholder.
• Clean the glass dome of the new bulb carefully with a soft cloth.
• Insert the new bulb so that the locating pin on the bulb body fits into the guide
in the bulbholder.
• Re-fit the bulb cover (12) into the optics unit (3) and slide the bulb cover back
down into position.
HEINE OMEGA 500 ® Headband
Selecting the position of the optics overband:
The overband (4) swivels and can be fixed into the following positions by means
of the position lock (5) (upwards for the rest position, down for working positions
1 or 2). To release the overband, press the position lock control (5) and rotate it.
Do not try to force the overband up or down. With practice a comfortable
working position can be selected and, when properly adjusted, the optics unit
will always return to the desired working position.
Fitting the headband rheostat HC50:
When fitting, ensure that the guide pin (15) of the headband rheostat HC 50 (14)
locates correctly in the opening (16) of the overband (4). Locate the connecting
cord between the power source and the headband rheostat in the cord clip (21)
at the back of the headband.
Fitting the position control:
Before fitting the position control (5) ensure that the positioning plate (19) is
swivelled upwards as far as possible. To do this, press the positioning plate (19)
and swivel it upwards simultaneously. Ensure that the optics over-band is in the
lower position and that the guide pin (20) locates in the opening (16). Now press
the position control (5) on to the guide (17) until it clicks into placed.
Removing the headband rheostat HC50 and position control:
The control of the HC 50 (14) and the position control (5) can be fitted on the
right- or left-hand side of the headband according to preference. To remove,
press the release (18) and pull the control off the headband.
Adjusting the optics:
Unscrew the control (2) so that the optics unit (3) is free to move. (The position of
this control can be reversed for left-handed operation if required).
Place the instrument on your head and adjust the height and circumference by
means of the adjusters (22) and (1) until a comfortable fit is achieved. The rear
part of the headband can be pivoted and is self-latching.
Adjust the optics to a position as close as possible to your eyes and view the
light spot at a distance of about 30 – 40 cm without accommodating. A small,
pencil-sized object should be sharply-focused (the eyepieces incorporate 2D
lenses. Spectacle wearers should examine through the "far" part of the spectacle
lens). Adjust the optics unit so that the light spot appears centred vertically in
position of the headband or to choose an alternative working position by pressing
your view and screw the adjuster knob in (2). (It may be necessary to correct the
lever (5) and swivelling the optics overband into a different position. If the light
spot needs horizontal adjustment, simply rotate the headband slightly to the side.
Adjust up the PD setting by closing first one then the other eye and observing an
object in the middle of the light spot while adjusting the appropriate eyepiece.
Repeat until the object is in the middle of the field of view, and a single image is
obtained. Take off the instrument and check that the PD is symmetrically-
adjusted. If not, repeat the selection procedure as above. Correct adjustment of
PD is particularly important when examining through a small pupil. Each user
should adjust the setting to match his own PD.
Every instrument includes two plano lenses, which can be exchanged for the 2D
lenses which are fitted as standard equipment.

Cleaning and maintenance

• Before cleaning, disconnect from the power source.
• Use only a suitable cloth to wipe the surfaces of the instrument.
• The instrument may be wiped clean with a damp cloth. Any cleaning agent
used must be suitable for use on plastic surfaces.
• An alcohol-based surface disinfectant can be used to clean the instrument.
• The use of a spray disinfectant and soaking or disinfection in a machine are
not permitted.
• Check the correct operation of the HEINE OMEGA 500
• Use the instrument only when you are sure that it is operating correctly.
