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”.

Battery Charging
The Nickel Metal Hydride batteries fitted in Scope portable transmitters are optimised for safety and

are faulty or if they refuse to maintain a charge, the equipment must be returned to Scope for servicing
and battery replacement. The transmitter unit must only be re-charged using the charger receptacle and
AC adaptor provided by Scope. Use of other adaptors or chargers will invalidate all warranties and may
result in damage to the equipment and/or injury to the user. In all such cases, Scope expressly excludes
liability for any damage or injury, howsoever caused.
