1 Warranty
To speed up the process of fault-finding and repair process detailed information about the faulty Total
Recall unit must be obtained from the customer and supplied to Tech Support with your enquiry.
1.1 Keeping Records of sold TR units / Accessory
As a reseller Arunta Comsec Pty Ltd requires you to keep records of units sold. These records will
contain no less than:
1: Date of Installation.
2: Item Sold.
2: Serial Number of the item and serial number of Total Recall if item is a spare part.
3: Channel configuration (if applicable).
4: Updates (software version & channel upgrades).
1.2 When you claim Warranty Repair
When you make a claim for warranty repair or replacement you will be asked to supply information
about the faulty product:
1: Date of Installation.
2: Serial Number of the item.
3: Nature of the fault.
4: Software version currently installed.
An RMA (Return Material Authorization) will be issued for the faulty product; this will be sent to
you by Fax, Email or with the new replacement parts. The faulty parts must be returned with a copy of
the RMA form to Arunta, Silverwater office as per the instruction on the bottom of the RMA form.
1.3 Before you contact us
It is always good practice to ensure that a unit has the latest software installed prior to contacting us
(except in cases where smoke has identified the fault). Quite often you will find that the new software
may have an enhancement that improves the performance of Total Recall. Generally the questions that
we will ask will be based on the latest software.
1.4 Warranty Statement
Normally you would contact your place of purchase or the distributor in your country for service (in
USA, Omnicron Electronics, www.omnicronelectronics.com
) for service. All Total Recall products
are covered by a 12-month depot warranty from date of original shipment. In the event that a
V4.00 Rev0.03 July 05 5
Warranty claim is to be handled by the manufacturer, your request must be communicated to Arunta
in writing. A Return Merchandise Authority (RMA) form will be sent to you for appropriate
completion and return before shipment of warranty replacement goods. The RMA form should be
enclosed with return of faulty goods. Arunta will process no warranty claim without the prior
authorisation of the Technical Services Manager. Dead on Arrival (DOA) units will be replaced
immediately following authorization.
Should product become faulty or otherwise malfunction, Arunta will repair or replace the product at
its discretion. All component parts will be supplied by Arunta and shipped to the Reseller via courier
service.
If a ‘part’ of the product is replaced under warranty, that ‘part’ must be retained by the Reseller for a
period of 12 months during which time, Arunta may, at its discretion, request the inspection of the
faulty part(s) or, in certain circumstances, the return to base of the faulty ‘part’. If the Reseller is
unable to produce faulty parts for which warranty replacements have been provided, then the Reseller
will be required to pay to Arunta the value of the replacement parts, as determined by Arunta.
All Total Recall serial numbers and parts serial numbers will be logged by Arunta, effective the date
of shipment.
Further details are available in the Total Recall Product Warranty document.
1.5 Returning Faulty Product.
If product needs to be returned to Arunta at any time, a Return Merchandise Authorisation (RMA)
number must first be obtained from Arunta. Returned products will not be processed if an RMA
number is not first obtained. The cost of returning any Total Recall product to Arunta is the
responsibility of the Reseller.
2 Maintenance
Total Recall needs regular maintenance to ensure its performance is maintained. As with any
computing device Total Recall has a fan that provides airflow across the processor to keep it cool and
a filter to ensure that the air is clean. Every month the filter will need to be washed in warm soapy
water and then rinsed thoroughly and allowed to dry completely prior to being replaced. New filters
are available.
