User Manual
WARNING!
This RF Amplifier is capable of eneratin hi h RF potential.
Touchin internal parts, or the connected antenna system, will
cause serious RF burns. Antenna systems should be installed
such that exposure by any person to RF fields cannot exceed safe
limits. The permitted limits vary from country to country. Expert
advice should be sou ht about the safe installation of this
transmission system.
RISK OF FIRE!
RF (Radio Frequency) ener y could cause i nition of combustible
surfaces durin fault conditions. Installation should be left to
qualified personnel. RF can cause burns to skin. Ensure antenna
systems and feeder cables are not situated near, or could fall
onto, any combustible surface.

IMPORTANT!
Always reduce the RF Output power to minimum before chan in
the transmission frequency. Once the new frequency is active,
slowly increase the RF output power control to provide the
required power output level.
WARNING!
Never operate this device without a suitable 50 ohm load
connected to the RF OUTPUT socket, or without a suitably
installed and matched antenna system connected. Althou h the
output of this RF amplifier is protected a ainst antenna load
faults, MIS-OPERATION MAY RESULT IN DAMAGE NOT COVERED
BY ANY WARRANTY.
IMPORTANT!
Correct operation of the coolin fans in this product is vital to
reliable continuous operation. Schedule bi-annual maintenance
checks. We stron ly advise the use of a standby RF amplifier
system for use durin maintenance events or fault conditions, to
prevent prolon ed breaks in transmission.
IMPORTANT!
Consideration should be iven to fittin a suitably rated UPS if
power interruptions are likely. Similarly, telemetry reset of power
may be advisable for equipment in remote areas, or havin
restricted access arran ements.

In
troduction

These instructions should be read in full before the RF amplifier is
operated.
The safety and operatin instructions should be retained for future
reference.
All warnin s on the RF amplifier and in the operatin instructions
should be adhered to.
All operation and user instructions should be followed.
Use of this device into a radiatin antenna requires a valid licence from
a Spectrum Mana ement Authority in most countries.
Use of this device as part of a transmission system, or combined
transmission system not specified by the manufacturer, may require
further testin to ensure that it remains compliant with the essential
requirements and other relevant provisions of current EU Low Volta e,
EMC and Radio Equipment Directives. Approval and clearance from the
Spectrum Mana ement Authority may also be required.
Installation must adhere to safety re ulations and the requirements of
the relevant authorities. We recommend that at least two people are
present durin installation. Keep a file containin installation
instructions and plans, includin details of the transmission system
(antennas, feeders, filters, etc) and operatin instructions for all
equipment at the transmission site at all times. Display posters
detailin first aid treatment and treatment for electrical shock, alon
with telephone numbers for contactin the emer ency services in the
event of personal injury.
Ensure antenna system li htnin strike protection is in place.
To reduce the risk of electrical shock, do not remove the cover, or any
screws. There are no user serviceable parts inside; refer servicin to
qualified personnel.
Do not expose this appliance to rain or moisture. The RF amplifier
should not be used near water. Care should be taken so that objects
do not fall - and liquids are not spilled - into the enclosure throu h
openin s.
Before operatin

To reduce the risk of fire, always replace fuses with the same type and
ratin .
The RF amplifier should be mounted into a well-ventilated standard 19
inch equipment rack, usin slide supports. It should be situated so that
its location or position does not interfere with its proper ventilation.
The RF amplifier should be situated away from heat sources.
The RF amplifier should be connected to a power supply only of the
type described in the operatin instructions or as marked on the unit.
Precautions should be taken so that the roundin or polarisation of
this appliance is not defeated.
The unit should be cleaned only as recommended by the
manufacturer.
The RF amplifier should be serviced by qualified service personnel if it
does not appear to operate normally, exhibits a marked chan e in
performance, has been subjected to shock, dama e, moisture, or if
forei n objects have in ressed.
The user should not attempt to service the RF amplifier beyond that
which is described in the Operatin Instructions. All other servicin
should be referred to qualified service personnel.
This appliance may become warm under normal operatin conditions.
Recycle accordin to WEEE re ulations.
