1. INTRODUCTION
The EZPRO25 RF module (Base Station Repeater) are a modular design, high performance
products used as APCO repeaters.
The radio system is available in the 806-870Mhz frequency band.
The proper functioning of any electronic device depends on its correct use. It is therefore
recommended that the instructions in this manual be followed.

2. UNPACKING AND CHECKING
The following elements are supplied in the box:
EZPRO25 RF
2 cables SMB RF
Installation manual
The equipment is supplied with all the modules already assembled in the rack and with
the RF cables connected. The modules in the basic configuration are: Control (RCPU P25),
Transmitter (RTX P25), power module (RPA P25), Receiver (RRX P25) and the power supply module
(RPS P25).
IMPORTANT: if any of these elements is missing or damaged, contact your dealer and / or
installer.
3. PREVIOUS CONSIDERATIONS
This manual contains information on instructions for installation, maintenance and use. Read
the following pages before using this equipment.
It is inadvisable to switch on the equipment without having previously connected the antenna or, in
case of the EZPRO25 RF, the 50Ω load to the TNC connector. Doing so may seriously damage the
equipment and even cause irreparable damage to the transmitter circuits. It is important to use an
antenna adjusted to the work frequency.
4. INFORMATION ON SAFETY AND ELECTROMAGNETIC COMPATIBILITY
The equipment has been designed according to the following standards:
ETSI ETS 300 392-2 - V2.5.2 (2005-11)
ETSI ETS 300 394-1 - V2.4.0 (2005-10)
ETSI EN 301 489-18 - V1.3.1 (2002-08)
EN 60950-1 - 2001
EN 60950-1:2001/A11:2004

These standards ensure the essential requirements established in article 3 of directive
1999/5/CE.
In any case, take the following points into consideration:
Most electronic equipment is susceptible to electromagnetic interference if it is not
duly protected. If the EZPRO25 RF is placed near unprotected electronic devices,
they may malfunction.
The EZPRO25 RF must not transmit without its antenna connected or, in case of the
EZPRO25 RF, without the 50Ω load in the TNC connector.
When installing the antenna, follow the guidelines for exposure of the human body to
high and low frequency electromagnetic fields. Follow the supplier’s / manufacturer’s
instructions.
Burns may be suffered if the antenna connector output of the power module (RPA
P25) is touched by bare skin when the EZPRO25 RF are transmitting with the
antenna disconnected.
Take care when handling the EZPRO25 RF. It has sharp edges, which may cut if
handled incorrectly.
Maintenance and repair of these repeaters must be carried out by qualified personnel
only.
Connect the EZPRO25 RF chassis to the earth intake in the cabinet where it is to be
installed.
Switch off the EZPRO25 RF before inserting/removing any of its modules.

6. INSTALLATION GUIDE
The following recommendations must be followed closely before starting up the EZPRO25 RF
module.
6.1 LOCATION
The EZPRO25 RF have been designed in the standard format of 19” / 3 units high, and so
they must be installed in cabinets with this format.
The EZPRO25 RF site must be permanent, well-ventilated and without vibrations.
6.2 POWER SUPPLY CONNECTION
DC power supply: check that the power supply source and/or the battery to be used meets the
voltage and current requirements necessary to supply the equipment:
Nominal voltage: 26.4VDC (range: from 21.6 to 28VDC)
Minimum source current: 10 A
There is a 15 A internal fuse in the RPS module (Ref. 1 of BSR) to protect the
equipment from over-voltage. There is a power control circuit in the RPS P25 module
in order to avoid an overcurrent condition.
If lead batteries are used, they are to be placed as far from the EZPRO25 RF as
possible to prevent corrosion in the repeater due to battery vapours. They should be
situated in a well-ventilated place.
Use the power supply connector provided (D013000) to connect the EZPRO25 RF to
the power supply source. Use a cable with 2.5 mm2 minimum diameter (or AWG-12).
Ensure that the connection is made with the correct polarity.
Ensure that the earth connection is made. Make this connection with a cable of
maximum diameter and minimum length.
NEVER use a gas or electricity conduit as an earth.

Revision: 00
6.3 ANTENNA CONNECTION
Choose the most adaptable antenna for the installation. The antenna must have an
impedance of 50 ohms to the equipment transmission frequency. Install the antenna
in accordance with the manufacturer’s instructions.
Use a cable coaxial, avoiding as much as possible large cable lengths. Cable
impedance is 50 ohms.
Measure the ROE of the installation. Never accept a ROE greater than 2.
If a duplexer module or a band pass filter is required, adjust them to the work
frequency before starting up.
6.4 SWITCHING ON THE EZPRO25 RF
Check the connections between the modules.
Check that the power supply source is connected correctly.
Check that the RF SMB cables are connected correctly (see Rear View diagram Ref.
10).
Check the connections of the antennas in the RPA P25 and RRX modules.
Only in case of the EZPRO25 RF check the 50Ω load is connected to the rear TNC
connector in the RPA P25.
Check that the Ethernet connections to the CNC/Gateway are in accordance with the
configuration.
Check that the RPS P25 module LED SUPPLY is on.
Activate the power on switch on the RPS P25 module.
Check that the 24V LED and the 13.2V LED on the RPS P25 module or the 26.4V
LED and 13.2V LED on the RPS P25 module are on and check that the LEDS ON are
switched on for the other modules.
Wait for the EZPRO25 RF to start up.
Check that the mobile equipment is registered in the EZPRO25 RF.
Note: see section 5 for more information on references for the different modules and LEDs.

7. CONFIGURATION
A EZPRO25 RF is configured via an NMS (Network Management System). To configure the
EZPRO25 RF, consult the NMS manual.
8. INCIDENTS
The repeater must be repaired by authorized technical personnel only. If a EZPRO25
RF failure occurs, the entire EZPRO25 RF must be replaced. If transmitter module is
damaged and there is not an entire EZPRO25 RF available to replace, set RTX P25 and
RPA P25 modules previously calibrated jointly. In last case and if is not possible to carry out
one of the two previous options, replace one of these two modules and make the gain
calibration again.
If an error or alarm occurs in the EZPRO25 RF, this is indicated in the corresponding LED for
each one of the modules. The following list shows the possible failures and their solutions.

8.2 ALARMS WITHOUT STATUS LEDS
8.2.1 Interference at the bsr.
This alarm is monitored in APCO P25 Network Management System (NMS). See “APCO P25
Event List” in NMS help.
An interference in the EZPRO25 RF is activated when a high number of invalid consecutive
receptions occurs at a EZPRO25 RF. An invalid reception is that which has a signal level higher than
the minimum level of reception of the carrier, but it is not recognised as a APCO P25 signal.
This alarm is switched off upon correct reception.
