1. INTRODUCTION
The RF Unit is the RF transceiver of Teltronic P25 systems, with a transmitter
output power of 100W. Therefore, this is a mandatory module in the infrastructure P25
network. It is manufactured following a robust mechanical modular design which allows
simple and economic maintenance.
The RF Unit is available in the following frequency bands:

 380 - 400 MHz

 410 - 430 MHz

 450 - 470 MHz

 764 - 806 MHz

 806 - 870 MHz
The modules that form the RF Unit are:
RPS (Repeater Power Supply P25)
RPA P25 (Repeater Power Amplifier P25)
RTX P25 (Repeater Transmitter P25)
RRX P25(Repeater Receiver P25)
BSYNC (RF Unit Synchronism) - OPTIONAL
RCPU P25(Repeater Control Processing Unit P25)
The proper operation of any electronic device depends on its correct use. It is
therefore recommended to follow the instructions in this manual.
CAUTION: Switch the RF Unit off before inserting/removing any of its modules.

2. UNPACKING AND CHECKING
The following elements are supplied in the box:
RF Unit
50Ω / 20W load termination
Power Supply Cable
Maintenance Cable
Two Ethernet Cables
The equipment is supplied with all the modules already assembled in the rack. The
modules in the basic configuration are: Power Supply module (RPS), Power Amplifier
(RPA P25), Transmitter (RTX P25), Receiver (RRX P25) and Control (RCPU P25).
Synchronism module (BSYNC) is necessary for testing purposes.
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.
Do not switch on the RF Unit without having previously connected the TX antenna
and the 50Ω load to the TNC connector. The equipment may be seriously damaged. It is
important to use an antenna adjusted to the RF Unit transmitter frequency band.
INFORMATION ON SAFETY AND ELECTROMAGNETIC COMPATIBILITY
The equipment has been designed to fulfil the applicable compliance regulations.
The equipment complies with Part 15 of the FCC Title 47 of the Code of Federal
Regulations. Operation is subject to the condition that this device does not cause harmful
interference.
The equipment complies with the applicable Part 90 of the FCC Title 47 of the
Code of Federal Regulations.

In any case, take the following points into consideration:
Most electronic equipments are susceptible to electromagnetic interference if
they are not duly protected. If the RF Unit is placed near unprotected
electronic devices, they may malfunction.
The RF Unit must not transmit without its antenna connected or 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 RF Unit is transmitting with the
antenna disconnected.
Take care when handling the RF Unit. 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 RF Unit chassis to the earth intake in the cabinet where it is to
be installed.

6. INSTALLATION GUIDE
The following recommendations must be followed closely before starting up the RF
Unit module.
6.1. LOCATION
The RF Unit has been designed in the standard format of 19” / 3 units high and it
must be installed in cabinets with this format.
The RF Unit 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 21.12 to 31.68 VDC).
Minimum source current: 20 A.
There is a 15 A internal fuse in the RPS module (Ref. 1 of RF Unit) to protect
the equipment from over-voltage. There is a power control circuit in the RPS
P25 module in order to avoid an over-current condition.
If lead batteries are used, they are to be placed as far from the RF Unit 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 RF Unit 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.

INSTALLATION
MANUAL

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 coaxial cable, 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
working frequency before starting up.
6.4. SWITCHING ON THE RF Unit
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 P25 modules.
Check the 50Ω load is connected to the rear TNC connector in the RPA P25.
Check that the RPS P25 module LED SUPPLY is on.
Activate the power on switch on the RPS P25 module.
Check that the 26.4V LED and 13.2V LED on the RPS P25 module are on and
check that the LEDS “ON” are switched on in the other modules.
Wait for the RF Unit to start up.
Note: See subclause 5.3 for more information on references for the different
modules and LEDs.

7. CONFIGURATION
A RF Unit is configured via an NMS (Network Management System). To configure
the RF Unit, consult the NMS manual.
8. INCIDENTS
The repeater must be repaired by authorized technical personnel only. If a RF
Unit failure occurs, the entire RF Unit must be replaced. If transmitter module
is damaged and there is not an entire RF Unit 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 RF Unit, this is indicated in the corresponding
LED for each one of the modules. The following list shows the possible failures and their
solutions.
