PREFACE 

 

Important Installation Information

 

 

It is the purchasers’ responsibility to determine the suitability of this equipment and its 
derivatives for any given application, Scope cannot give specific advice in this manual, 
as each use will require independent evaluation. 
 
Scope has, wherever possible, employed extra safeguards to monitor the system’s 
performance.  Certain system installations, operational requirements or budgets may, 
however, limit the effectiveness of these safeguards. Again, the suitability of the system 
for any given application must therefore be decided by the installer and their customer, 
relative to the application and risk. 
 
Good working practice dictates that a suitable system installation log must be 
generated, together with a record of the dates when the system has been manually 
checked, (with the aid of signal strength meters etc.) enabling the system performance 
to be compared with the original installation data. 
 
For UK equipment, Scope has no control of the use and application of the frequencies 
issued by OFCOM. Some equipment that is licensed may have greater protection than 
other equipment which is operated on a WT Act License Exempt basis. 
 
The supply of this equipment is governed by our standard terms and conditions of sale, 
which can be found on the reverse of all order acknowledgements*, proforma invoices*, 
delivery notes, price lists and invoices. Alternatively, these can be provided on request. 
 

* Faxed proforma invoices and quotations refer to “conditions available upon request”.
