Part 1 HARDWARE
1. Safety
Any personnel involved in installation, operation or service of Fiplex repeaters must understand
and obey the following:
Any repeater, including this repeater, will generate radio signals and thereby give rise to
electromagnetic fields that may be hazardous to the health of any person who is extensively
exposed to the signals at the immediate proximity of the repeater and the repeater antennas.
FCC Radiation Hazard Warning
To comply with FCC RF exposure requirements in Section 1.1307 and 2.1091 of FCC Rules, the
antenna used for this transmitter must be fixed-mounted on outdoor permanent structures with a
separation distance of at least 2 meter from all persons.
R&TTE Compliance Statement
This equipment complies with the appropriate essential requirements of Article 3 of the R&TTE
Directive 1999/5/EC.
BTS chassis, Repeater, feeders, donor antenna, service antenna/s and auxiliary equipment (splitters, tabs,
.etc) are required to be bonded to protective grounding using the bonding stud or screw provided
with each unit.
Static electricity means no risk of personal injury but it can severely damage essential parts of
the repeater, if not handled carefully.
Parts on the printed circuit boards as well as other parts in the repeater are sensitive to
electrostatic discharge.
Never touch printed circuit boards or uninsulated conductor surfaces unless absolutely
necessary.
If you must handle printed circuit boards or uninsulated conductor surfaces, use ESD protective
equipment, or first touch the repeater chassis with your hand and then do not move your feet on
the floor.
Never let your clothes touch printed circuit boards or uninsulated conductor surfaces.

2. Installation
Sitting the repeater
Fiplex nanoSAW family of repeaters is designed for indoor use.
If repeater needs to be mounted outdoors, weather proof cabinet should be provided in order to
preserve weather tightness.
Mounting
nanoSAW is ready for wall mount using four fixing screws.
Figure 1
Figure 1 shows holes pattern for fixing screws.

3. Commissioning
Connection
1. Connect service antenna (“TO MOBILE” port) and donor antenna (“TO BASE” port) coaxial
cables. SMA type female connectors are used in the repeater.
2. Once RF ports of the repeater are properly loaded connect the DC plug from power supply to
nanoSAW DC input.
The repeater powers on when power supply is connected to the AC line, and nanoSAW is
properly feed with DC voltage. Blue led labelled “PWR ON” must be on, under normal power
conditions.
Figure 2
Figure 2 shows DC input plug position.

Starting operation
Prior to the following steps refer to section 2 of this manual in order to properly install pFOMS.
1. Setup desired filter configuration using pFOMS (only for programmable band selective and
programmable channel selective models).
In programmable band selective repeaters user must set up start and stop frequency.
In programmable channel selective user must set up center frequency, nanoSAW repeaters are
a special case of programmable selective repeater, where number of channels is equal to one.
For both types of repeaters user could set up start, stop or center frequency either using
absolute values (in MHz) or using ARFCN.
For fixed bandwidth repeaters this feature will not allow user to make changes, so, skip this step
for fixed bandwidth models.
2. Setup desired operating gain using pFOMS. UL and DL chain are independent, so both
values must be set.
For nominal gain of the repeater these values must be set to zero.
Figure 3
Figure 3 shows how to set up manual attenuation values.

Status Indicators
There is an indicator panel located at the front of the repeater. This led panel works as a status
monitor, in order to advice different operational conditions of the repeater.
1. Power indicator
Every time the repeater is plugged to DC power supply, and under normal conditions of
operation, led labelled PWR ON will be ON.
Figure 4
Figure 4 shows PWR ON led location.
2. Automatic Gain Control Indicator
When Automatic Gain Control circuitry is active led labelled AGC UL and/or AGC DL will be ON.
Please see Automatic Gain Control for further functional explanation.

Automatic Gain Control (AGC)
Automatic Gain Control circuitry is intended to keep repeater’s output power at a fixed level
when input signals exceed maximum values, avoiding quality signal degradation by
intermodulation generation.
When AGC is active AGC UL and/or AGC DL leds will be ON, this means that signal level from
donor and/or service area site, plus repeater gain produces an output power that is above the
maximum composite output power of the repeater. This should not be considered an undesired
working condition, far from that; this is the best operating condition because you are getting the
maximum composite output power available from the repeater.
Anyway is a good practice to increase attenuation (reducing gain), until AGC led turns off, this
operation releases AGC circuitry dynamic range.
Also is a good practice to check signals from donor site to ensure that undesired signals are not
being amplified by the repeater, or even desired signal levels are not excessively high taking
repeater to an overload condition.
Overload Protection
When AGC circuit reaches its limit, the power amplifier stage is shut down to prevent harmful
distortion and potential damage to the repeater. After approximately ten seconds the system
checks if overload condition is still present, if this happens, amplifiers will remain off. This cyclic
check will continue until condition that makes AGC circuitry reach its limits disappears.
Conditions that can cause AGC to reach its limits include the presence of one or more very
strong channels, a strong in-band noise source, or amplifier oscillation due to poor antenna
isolation.
Downlink Signal Indicator
Summarizes downlink repeater output. Indicates bad, poor, good, very good and excellent signal
levels as follows:
Bad RSSI, all leds off
Poor RSSI, first led ON
Good RSSI, first and second leds ON
Very Good RSSI, first, second and third leds ON
Excellent RSSI, all leds ON
Laboratory Measurements
For specific parameters verification and laboratory tests, please contact factory.
Detailed procedures, recommended tests set up, and a knowledge engineering team will bring
adequate support to perform this measurements in a comfortable and safely way.
