9 Warranty
9.1 Warranty period
The devices have a 24-month warranty period. The warranty period starts on the day the new unit is
purchased. There is no warranty on standard or rechargeable batteries (AA/AAA type).
Consumables or defects causing a negligible effect on operation or value of the equipment are not
covered.
The warranty has to be proven by presentation of the original or copy of the purchase receipt, on which
the date of purchase and the unit-model are indicated.
9.2 Warranty handling
A faulty unit needs to be returned to an authorized service centre including a valid purchase note and
a filled in service card.
If the unit develops a fault during the warranty period, the service centre will repair any defects caused
by material or manufacturing faults free of charge, by either repairing or exchanging the faulty units or
parts of the faulty units. In case of replacement, colour and model can be different from the original
purchased unit.
The initial purchase date shall determine the start of the warranty period. The warranty period is not
extended if the unit is exchanged or repaired by the service centre.
9.3 Warranty exclusions
Damage or defects caused by incorrect treatment or operation and damage resulting from use of non-
original parts or accessories are not covered by the warranty.
The warranty does not cover damage caused by outside factors, such as lightning, water and fire, nor
any damage caused during transportation.
No warranty can be claimed if the serial number on the units has been changed, removed or rendered
illegible.
Any warranty claims will be invalid if the unit has been repaired, altered or modified by the buyer.
