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.
For U.S. only:
Federal law restricts this device to sale by or on the order of a
Physician or Practitioner!

Handling and operation
The device is not suitable for eye examinations.
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.
Always use the device in combination with one of the filter inserts
(polarizing filter or neutral density filter).
For examination of hard to reach lesions use the small contact plate (1c) in
place of the standard contact plate (1a).
Use DELTA 20 Plus with Immersion-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.
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 DELTA 20 Plus 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. Apart from that 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.
An electrical conducting connection between camera, PC and a mains
power source is not permissible.
For documentation with a digital camera only use the HEINE photo
adaptor and our recommended adaptor from the digital camera adaptor
range.
Hygienic Cleaning / Processing
The contact plates have to be cleaned and /or disinfected after operation.
Preparation:
Detach the contact plate from the instrument head. Remove the instrument
head from the handle.
Cleaning:
Wipe down the instrument head with a damp cloth (soaked in plain water, no
added agents). Then rub dry.
The device may be damaged by liquids. It must not be rinsed in running
water or immersed in water.
