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  1  hour’s  labour,  at  IRT’s  current  labour  charge  rate,  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. 

7.

 

For  situations  when  “

No  Fault  Found

”  for  repairs,  a  minimum  charge  of  1  hour’s  labour  will  apply, 

whether the equipment is within the warranty period or not. Contact IRT for current hourly rate. 

 
Please note that all freight charges are the responsibility of the customer. 
 
The  equipment  should  be  returned 

to  the  agent  who  originally  supplied  the  equipment

  or,  where  this  is  not 

possible, to IRT directly. Details of IRT’s direct address can be found at I.R.T. Communications’ website.
