10 Topcom warranty
10.1 Warranty period
The Topcom units have a 24-month warranty period. The warranty period starts on the day the new unit
is purchased. The warranty on batteries is limited to 6 months after purchase. 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 purchase receipt, on which the date of
purchase and the unit-model are indicated.
10.2 Warranty handling
A faulty unit needs to be returned to a Topcom service centre including a valid purchase note.
If the unit develops a fault during the warranty period, Topcom or its officially appointed service centre
will repair any defects caused by material or manufacturing faults free of charge.
Topcom will at its discretion fulfil its warranty obligations 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 Topcom or its appointed service centres.
