SCPUHF Paging Transmitter System 
SCPUHF  Issue 2 
6 
Some major points to consider when installing equipment: 
1  Never install antennas near or adjacent to telephone, public address or data 
  communication lines or overhead power cables. 
2  Avoid, where ever possible, running antenna coax alongside other cables. 
3  Avoid mounting the transmitter in the immediate vicinity of telephone exchanges  or 
computer equipment. 
4  Always use 50 ohm coaxial cable between the antenna and the  transmitter. If 
cable runs exceed 5 metres, always use low loss 50 ohm cable such as RG213 or 
UR67. 
Coaxial cable intended for TV, Satellite or CCTV installations is normally 75 OHM and 
therefore totally unsuitable for any transmitter installation manufactured by Scope. 
5  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 circuit boards within this equipment may be harmed by Electrostatic  Discharge 
(ESD). Installers should ensure that both themselves and the system’s chassis are 
grounded before beginning any installation, and should ensure that adequate anti-
static procedures are adhered to at all times. 
7  Warning! Never transmit without an aerial attached to the transmitter 
8  Warning! Carefully check the Installation section in this manual covering terminal 
connections prior to installation. Damage caused by incorrect connection is the 
responsibility of the installer! 
The following procedure must be adhered to when installing the SCPUHF paging system. 
Ensure you have taken into consideration all of the above information before selecting the 
location for your transmitter. If in doubt please feel free to telephone the technical helpline 
on (01803) 860710. 
1  Remove the cover from the SCPUHFTX transmitter unit by undoing the two Pozi 
head screws located on the front face of the unit (see Diagram 1). For the mains 
powered PSCPETX transmitter, slacken the two screws at either end of the cover 
(see Diagram 2). 
2  Carefully lift off the cover and place to one side.
