Maintenance & storage 

 

Maintenance: 

 
No regular maintenance is required. 
 
Care however should be taken to ensure that all connectors are kept clean and free from contamination of any kind. 
This is especially important in fibre optic equipment where cleanliness of optical connections is critical to 
performance. 
 

Storage: 

If the equipment is not to be used for an extended period, it is recommended the whole unit be placed in a sealed 
plastic bag to prevent dust contamination. In areas of high humidity a suitably sized bag of silica gel should be 
included to deter corrosion. 
 
Where individual circuit cards are stored, they should be placed in antistatic bags. Proper antistatic procedures 
should be followed when inserting or removing cards from these bags. 
 

Warranty & service

 

 
Equipment is covered by a limited warranty period of three years from date of first delivery unless contrary 
conditions apply under a particular contract of supply. For situations when “

No Fault Found

” for repairs, a 

minimum charge of $A100.00 will apply, whether the equipment is within the warranty period or not. 
 
Equipment warranty is limited to faults attributable to defects in original design or manufacture. Warranty on 
components shall be extended by IRT only to the extent obtainable from the component supplier. 

 
Equipment return: 

Before arranging service ensure that the fault is in the unit to be serviced and not in associated equipment. If 
possible, confirm this by substitution. 
 
Before returning equipment contact should be made with IRT or your local agent to determine whether the 
equipment can be serviced in the field or should be returned for repair. 
 
The equipment should be properly packed for return observing antistatic procedures. 
 
The following information should accompany the unit to be returned: 
 

1.  A fault report should be included indicating the nature of the fault 
2.  The operating conditions under which the fault initially occurred. 
3.  Any additional information which may be of assistance in fault location and remedy. 
4.  A contact name and telephone and fax numbers. 
5.  Details of payment method for items not covered by warranty. 
6.  Full return address.
