General Conditions of Warranty
Instead of the statutory warranty time period of 2 years, HEINE will grant a
guarantee of 5 years from the date of the consignment of the goods ex works,
concerning its equipment (excluding disposables, e.g. bulbs, single-use
articles, and rechargeable batteries).
The guarantee covers irreproachable workmanship, on condition of the proper
use of the equipment and the observation of the operating instructions. During
the warranty- and guarantee time period, errors and deficiencies arising on
the equipment will be rectified free of charge, in so far as such are evidenced
by defective materials, processing and/or constructional errors. Should buyer
complain of a material deficiency during the warranty time period, then the
onus of proof is always to be on the orderer, that the product was defective
already upon receipt of the goods. The statutory warranty and the guarantee
do not apply to loss or damage caused by wear and tear, negligent use, the
non-employment of original HEINE components and/or spares (in particular
bulbs, as these have been especially developed for HEINE instruments in
accordance with the following criterions: colour temperature, useful service
life, safety, optical quality and performance. The statutory warranty and the
guarantee do not apply to interventions by persons not authorised by HEINE
or when the operating instructions are not observed by the customer. Any
modification of a HEINE product with parts or additional parts which do not
conform to the original HEINE specification will invalidate the warranty for
the correct function of the product and further invalidate any warranty claims
which result from such a change or modification. Further claims, in particular
claims for replacement of loss or damage, which are experienced otherwise
than directly on the HEINE product itself, are hereby excluded.

(dermatoscopy) by medical professionals.

tation of pigmented lesions and do not replace the diagnosis of the examiner.

Setting up the HEINE DELTA
®
Electrical and mechanical compatibility of the HEINE DELTA
dermatoscope can be assured only when used in conjunction with 2.5V
and 3.5V HEINE battery or rechargeable handles with HEINE AV or
TL-connectors.
Connecting DELTA 20 Plus with a handle:
Hold the HEINE handle with one hand. Rotate the chequered interlock ring
counterclockwise with your thumb and index finger of the same hand.
Push DELTA 20 Plus into the lock and release the chequered ring. To remove,
reverse the procedure. Please always check whether the instrument head is
safely locked.
Assembly of Filter insert and Contact Plate:
Attach the insert 1f to the Contact Plate 1d or 1e and rotate the insert to lock
the bayonet connection. Please repeat the procedure with insert 1g and
Contact Plate 1a or 1c. To disassemble the filter from the Contact Plate,
please reverse the procedure
Attachment of Contact Plates:
The contact plates (1a, 1b, 1c, 1d, 1e) are attached by a bayonet connection.
To remove the contact plate turn it counterclock-wise and pull it away from the
Dermatoscope. To attach, reverse the procedure. Always check whether the
bayonet is safely locked.
Insert batteries into the handle:
Please make sure that the on/off switch (7) is turned to 0.
Rotate the baseplate (6) of the handle counterclockwise to open the battery
cabinet. Insert the batteries (LR 14) with the plus pole facing towards the
instrument head as described in the instructions of the handle. Attach the
baseplate.
Please follow the detailed instructions of the user manual of the handle.
Please use original HEINE handles in combination with DELTA 20 Plus.
In case of using other accessories, HEINE warranty is voided.
Handling and operation
Always use DELTA 20 Plus in combination with one of the filter inserts
(polarizing filter or neutral density filter).
Do not look directly into the light source to avoid dazzle from the intense,
white, light emitting diodes (LED's).
It's not allowed to modify the medical equipment.
Contact Plates:
The contact plate (1a) is attached by a bayonet connection. To remove the
contact plate turn it counterclockwise and pull it away from the Dermatoscope.
To attach, reverse the procedure. For examination of hard to reach lesions use
the small contact plate (1b) in place of the standard contact plate (1a).
Use with Immersions-Contact Plate (1a, 1b, 1c):
Prepare the skin by moistening with Dermatoscopy-oil (use a cotton swab) or
disinfectant spray.
Turn the Dermatoscope on by rotating the on/off ring (7) at the handle. Place
the instrument gently so that the lesion is in the center of the contact plate (1a).
The examiner's eye should be as close to the eye-piece (3) as possible.
Adjust the focus ring until a crisp, clearly-focused image is obtained. For
Dermatoscopy, use the instrument only with the HEINE contact plate (1a, 1b)
correctly-fitted.
Use with polarizing Contact Plate (1d, 1e):
When using the polarizing Contact Plate, it is not necessary to prepare the
skin with liquids like Dermatoscopy-oil or disinfectants. The general operation
is the same as the procedure described above.
Brightness Control:
The voltage-regulating electronics of the HEINE DELTA
scope guarantee constant brightness. Pressing one of the two buttons on the
instrument (2) will reduce the brightness by 50% and will turn off 2 of the 4
LED's resulting in lateral illumination for improved contrast when viewing the
pigmented structure.
For documentation with a digital camera only use the HEINE photo
adaptor and our recommended adaptor from the digital camera adaptor
range.
The HEINE DELTA 20 Plus Dermatoscope is not suitable for Eye
®
Examinations.
Risk of electric shocks: Do not connect camera with the computer
(USB cable) or any extend power supply!
For safe operation only use power sources which are designed and
specified by HEINE for use in medical applications.
