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”.
Licence
For the UK, this equipment is intended for use on the 433 and 458 MHz Short Range Device
licence exempt radio frequencies and programming has been restricted to these ranges.
For use in the USA, this equipment will require a licence. Consult your dealer for further advice.
For further technical rules governing the use of this equipment you should obtain the FCC Rules
and Regulations, Title 47 Part 80 to end, including parts 90 and 95 available from the US Gov
Printing Office, GPO Book store, FCC Office or www.fcc.gov/oet/info/rules/ .
The FCC ID for this equipment is: JRNUSAWAVETRACK

Equipment Applications
It is the user’s responsibility to determine the suitability of the Scope products for any given
application. Scope, including its subsidiaries and Distributors, cannot provide specific advice
within this manual, as each application will require independent evaluation. Common sense
dictates that certain applications may require back up systems to cover in the event of mains or
equipment failure.
All applications should be thoroughly assessed by the installer in conjunction with the customer
so as to minimize risk.
Scope has no control of the use and application of the frequencies issued by the
FCC or OFCOM. Some equipment that is individually licensed may have a greater degree of
protection than other equipment that is operated on a FCC License Assignment basis. The
following information, however, may be of benefit.
Equipment Testing
Range tests should be carried out at least once a week on portable radio equipment, more often
when critical criteria apply. This should involve testing the unit past the limit of its required
working range.
Good working practice dictates that a suitable system installation log, covering both portable and
fixed equipment must be generated, together with a record of the dates when the system has
been manually checked and/or serviced, (with the aid of suitable test equipment etc.) enabling the
system performance to be compared with the original installation data.
The frequency of the tests required will vary between applications. If portable equipment has
been dropped or is worn by a person involved in an accident, the unit should be tested again
before re-use.
It must be stressed that the physical range tests are essential and that any construction work or
movement of plant or equipment could alter the signalling capability of the unit. Radio equipment,
like any other requires servicing from time to time to ensure that it is operating to its optimum
performance. It is therefore essential that equipment is inspected and tested by authorized
service centres at least once a year.
Literature
Scope Communications UK Ltd, the manufacturer, in conjunction with its distributors operates a
policy of continual improvement, and therefore reserve the right to modify or change any
specifications without prior notice.
While every possible care has been taken in the preparation of this manual, Scope does not
accept any liability for technical or typographical errors or omissions contained herein, nor for
incidental or consequential damage arising from the use of this material.
Liability
Scope does not accept liability for any damage or injury, howsoever caused as the result of
misuse of this equipment. It is the responsibility of the user to ensure that the equipment is
operated in the manner for which it was intended and that it is the correct item of equipment for
the required task.

Installation
The LTX board and wire antenna must be mounted in a non-metallic, non-
conductive enclosure. Note that some plastic enclosures have a metallic coating
applied to the inside for screening purposes, these would be totally unsuitable
and would result in severe attenuation or complete loss of signal strength.
See diagram below for positioning of the wire antenna. Care should be taken to
avoid strain on the soldered termination and other cables should be kept clear of
the antenna. Do NOT attempt to shorten, alter or replace the antenna. This may
severely affect performance and will void all warranties and Type Approvals.
Similarly, if using a metal-cased battery such as a PP3 style cell, avoid
positioning the battery next to the antenna.
The input trigger cables should be kept as short as possible (< 1mtr) and should
not be grouped with any other cabling (especially power, telecom and any data
cabling). Ensure that these are volt-free ("dry") contacts only. Applying voltage to
these inputs will irreparably damage the LTX unit.
Environment: note that where the transmitter is to be used in a non-temperature
controlled environment (e.g. an unheated outbuilding or outside), the enclosure
will need to be suitably protected from dust & moisture ingress (at least IP67
rated) and adequately protected to prevent internal condensation, which will
otherwise damage the LTX board beyond repair. The operating temperature
range of the LTX (see Specification section below) must also be observed.

Some major points to consider when installing equipment:
1 Never install transmitters near or adjacent to telephone, public address or
data communication lines or overhead power cables.
2 Avoid, wherever possible, running the antenna alongside other cables
(see LTX mounting diagram) .
3 Avoid mounting the transmitter in the immediate vicinity of telephone
exchanges or computer equipment.
4 Also remember that the performance of the system will be effected by the
type of material the unit is mounted on and its surroundings.
The following is a list of materials that this transmitter will be adversely
affected by if mounted on or if mounted in close proximity to:
a) Foil back plasterboard
b) Metal mesh or wire reinforced glass
c) Metal sheeting, large mirrors or suspended ceilings
d) Lift shafts
All of the above can reflect radio waves and thereby reduce the capability
of the transmitter to perform its desired functions.
6 The LTX circuit board may be harmed by Electrostatic Discharge (ESD).
Installers should ensure that adequate anti-static procedures are adhered
to at all times during fitting and connection.
7 Warning! Never transmit without the aerial attached to the transmitter
8 Warning! Carefully check the Configuration section in this manual prior
to installation. Damage caused by incorrect connection is the responsibility
of the installer!
