Most systems are sold with a RTB (Return To base) warranty unless this option was upgraded at the point of purchase. As standard the issued warranty will cover parts and labour for the specified warranty period. The terms & conditions laid out in the sales agreement (specifically section 8. Warranties and Representations) state that: 8.4 Seller agrees to repair or replace (at Seller’s option) all Products which fail to conform to the relevant warranty set out in clause 8.3 provided that: 8.4.1 Notification of the defect is received by Seller within the warranty period specified above; 8.4.2 Allegedly defective Products are returned to Seller with Seller’s prior authorisation within thirty (30) days of the defect becoming apparent; and 8.4.3 The Products have not been altered, modified or subject to misuse, incorrect installation/maintenance, neglect, accident or damage by excessive current or used with incompatible parts. 8.4.4 Replacement Products shall have the benefit of the applicable warranty for the remainder of the applicable warranty period. 8.5 If the Seller complies with clause 8.4 it will have no further liability for a breach of the relevant warranty set out in clause 8.3. 8.6 Allegedly defective Products returned to Seller in accordance with 8.4.2 will if found by Seller on examination not to be defective be returned to Buyer and a charge made for examination and testing. In the unfortunate event that your system develops a fault and our engineers assess and diagnose either remotely or at our support lab, that the fault is determined to be as a result of such inadequate maintenance, then subject to clause 8.4.3 as laid out in your terms & conditions, WS reserves the right to apply a charge for the repair. This will be communicated before any such work is carried out and applies throughout the contracted warranty period.
