Introduction & general information structure
This manual contains all informa on for installa on and maintenance of DS
transmi ers and is divided into two parts: the fi rst concerning operator that has to
use equipment, the other concerning maintenance technicians. The two sec ons are
separated by one blue page to quickly iden fy them.
The operator who normally has experience in using the equipment should not try
to perform any ac on which has been classifi ed as belonging to the maintenance
technician. Any incorrect opera on may cause damage to equipment electronics
and can be also poten ally dangerous for operator’s safety.
The RF power amplifi er has been designed for con nuous wave (CW) modes.
Technological cu ng-edge solu ons and latest genera on materials (such as sixth
genera on LDMOS) ensure a high standard of quality and robustness.
Hazardous Voltage Warning
WARNING:
Voltage within equipment is high enough to endanger life!
Do not remove external and internal covers!
this opera on is to be done by qualifi ed and authorized
personnel only!

General Safety Recommendations
All work on transmi er system as well as installed units, e-g- the VHF/FM transmi er,
may only be carried out by trained personnel capable of iden fying dangerous
situa ons or condi ons. Take note of the following:
• Before working on a transmi er system, that is even before removing the VHF/
FM transmi er ensure that the correponding system documenta on is consulted.
• Before workign on an open unit ensure that the fuse ahead of the unit is
disengaged or the power cable to the unit is disconnected.
• Note that when service work is carried out, e.g. measurements or se ngs are
made during transmi er opera on, voltage carrying parts are not always secured
against touching.
• All work is to be carried out with great cau on.
CAUTION!
The VHF/FM transmi er does not possed a mains switch. Even when the transmi er
system is in the “OFF” state, voltages are s ll present at the assemblies of the VHF/FM
transmi er, e.g. mains power at the input of the power supply module is live and the
fan is in opera on.
Assemblies with components incorpora ng toxic substances are labelled as follows:
A warning sign as shown in the adjacent fi gure is glued to a component incorpora ng
a Toxic substance of glued in the vicinity of the component.
Warnung
Dieses Bauelement enthält Beryllium-Oxid, das in fein verteilter
Form giftig ist. Bei bestimmungsgerechter Verwendung des
Bauelementes entstehen keine Gefahren.
Gegebenenfalls sind entsprechende Sicherheits- und Umwelt-
vorschriften zu beachten.

Introduction
The transmi er DS is designed with all the latest technologies, such as high effi ciency
using the latest genera on LDMOS transistor and high effi ciency power supplies. We
used a modern interface and performance using a color display with touch screen,
with easy management so ware and easy to use. Each transmi er DS is equipped
with a LAN interface with the possibility of remote control completely the transmi er
opera on.
The transmi er DS is equipped with all audio inputs including Audio IP (as op on),
Fig. 1: Front View of the VHF/FM Transmi er DS30-50-100-300-500-1000
The VHF/FM transmi er DS30-50-100-300-500-1000 is intended for the transmission
of frequency modulated broadcasts in mono or stereo. It works with broadband
characteris cs in the VHF frequency range from 87.5~108 MHz and can be operated
with any frequency in this range without alignment.
The transmi er output power is variable between 10 W and 30 W. The transmi er is
available with diff erent remote control ports. It can store up to six broadcast programs
including program specifi c parameters such as frequency, RF output power, modula on
type, RDS, AF level and devia on limi ng. DS30 transmi er is equipped with a LAN
interface that permits the complete remote control of the transmi er opera on via
SNMP or Web Server.

CAUTION!
All the changes to the Transmi er must be done in Local mode.
In this mode the Transmi er is completely manually controlled.
All se ngs are under menu control from LCD colour display with touch screen
except for transmi er “ON/ST-BY” switching and local/remote switch-over.
The current opera ng status is displayed on the LCD colour display with touch
screen. During an opera ng procedure the individual menus, the set func ons and
parameters as well as the polled measured values are shown. LED’s on the front
panel give a status indica on of important opera ng parameters.
In remote control mode, the front panel keys and the LCD colour display with
touch screen are inhibited. In local mode, no se ngs are possible via the remote

Installation
The package contains:
• 1 DS Transmi er
• 1 CD-ROM with the User Manual
• 1 Mains power cable
• Accessories and spare parts (screws/front panel handles)
Unpacking
First power-on and setup
Unpack the transmi er and perform a visual inspec on to determine that no
apparent transport damages has been incurred. Ensure that all connectors are in
perfect condi on.
Connect the RF OUT of the transmi er to the antenna cable or a dummy load
capable of dissipa ng the output power.
WARNING!
Electric shock hazard! Never handle the RF output connector
when the equipment is powered on and no load is connected.
Injury or death may result.
Ensure that the POWER switch on the rear panel is set to OFF.
Connect the mains power cable to the MAINS connector on the rear panel.

Quick start
Before power on the transmi er, make sure that the it is connected to the antenna
or to an adeguate power dummy load; connect the mains plug and turn on the
transmi er. If you want to turn on the transmi er with the lowest possible power,
keep pressed the Home/Back and turn on the transmi er
The display will show some informa ons of the transmi er se ngs, such as:

Menu
Display and programming of the transmi er is through the LDC display touch screen.
From the fi rst screen at power, as previously explained, can be accessed through the
menu bu on to the submenu of the Audio, Frequency, Power, Se ng, Memories and
Alarm.
Touching a symbol on the display is accessed directly from the menu chosen and you
can implement all the changes you want. Each menu is simple and intui ve without
the need for any manual so that all changes following what appears on the display.
Following are the main screens that allows the display.
That related to memories need an explana on, the transmi er can store six diff erent
se ngs in six memories, these can be called either remotely or locally; This is used in
