Opticron HDF - Manual (Page 2)

Guarantee
Opticron HDF Eyepieces are of a very high quality both in their performance
and construction. We guarantee some parts in these instruments for up to 10
years under the following conditions:
(i)
In the case of defects attributable to faulty processing or materials, we will
assume responsibility for the labour and material costs during the first 5
years after purchase. We reserve the right to decide whether defective parts
should be repaired or replaced.
(ii) During the next 5 years we will assume responsibility for material costs
only, charging corresponding labour costs.
(iii) We will accept no liability for damage caused by incorrect use, water
penetration or for any repairs or actions which have been carried out
outside our firm.
(iv) Parts such as rubber eyecups and rubberised coatings etc. are excluded
from the guarantee.
This guarantee is in addition and does not affect your statutory rights.
Care and cleaning
Opticron HDF eyepieces require little maintenance but occasionally the
outside surface of the eyelens will need cleaning. To avoid damaging this
surface please read the following carefully.
(i) Gently remove excess dirt and dust using a compressed air device or
blower brush.
Caution: Hard and persistent rubbing of dirty surfaces can cause
abrasive scratches on the surface of the glass which may distort
viewing.
(ii) Breathe on exposed glass surface and then wipe with an optical
cleaning cloth (code 30277) in a circular motion until the surface is
clean again.
Do not attempt to dismantle the eyepiece as this will invalidate the
guarantee.
