8. TOPCOM WARRANTY
8.1. 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.
8.2. 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.
8.3. WARRANTY EXCLUSIONS
Damage or defects caused by incorrect treatment or operation and damage resulting from use of non-original parts or
accessories not recommended by Topcom are not covered by the warranty.
Topcom cordless phones are designed to work with rechargeable batteries only. The damage caused by the use of
non-rechargeable batteries is not covered under 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 or by unqualified, non-
officially appointed Topcom service centres.
