BDA TEST AND INSTALLATION PROCEDURE

1. INSPECTION

CAUTION: A minimum separation distance of 20

centimeters between the transmit antenna and

nearby persons must be maintained. If this

separation distance is not maintained, the device

may not be in compliance with FCC RF Exposure

rules.

Open the enclosure of the bi-directional amplifier (BDA) and carefully inspect the inside

assembly of the unit.

Verify that all components are properly secured to the base of enclosure, there are no

loose parts, and all interconnections are reliable. Carefully close the enclosure.

Unpack the outdoor and indoor antennas and inspect the content. Verify that there are no

loose parts or rattling in the antennas. Make sure that antennas are not deformed.

2. SITE INSTALLATION

2.1 "Donor" (outdoor) Antenna Installation

On the roof of the building chose the location of the "donor" Yagi antenna. Point the

antenna towards the "donor" site. Connect the mobile phone or spectrum analyzer to the

antenna using short cable with type "N" connector on the antenna side and proper adapter

on the test equipment side. Adjust the position of the antenna for the maximum reading.

The average power level should not be below -85 dBm. Record the measured data. Install

the antenna following instructions of the antenna manufacturer.

CAUTION: A minimum separation distance of 20

centimeters between the transmit antenna and

nearby persons must be maintained. If this

separation distance is not maintained, the devicemay

not be in compliance with FCC RF Exposure rules.

CAUTION

Use caution working with the bi-directional amplifier.

Disconnect the 115 VAC from the amplifier prior to

inspection.

BDA TEST AND INSTALLATION PROCEDURE 1. INSPECTION CAUTION Use caution working with the bi-directional amplifier. Disconnect the 115 VAC from the amplifier prior to inspection. CAUTION: A minimum separation distance of 20 centimeters between the transmit antenna and nearby persons must be maintained. If this separation distance is not maintained, the device may not be in compliance with FCC RF Exposure rules.

.2 Surge Protector Installation Connect the cable run to the antenna and pass it through the roof manifold. Inside of the building find a location for the surge protector near the construction ground where it can be reliably grounded. Install the surge protector and connect the cables to both sides. Bring the cable run to the BDA location. Using a spectrum analyzer or mobile phone, measure the signal from the "donor" site. It has to be from 1 dB to 3 dB below the antenna output level.

It should not exceed +24.8 dBm for a single channel or +19.5 dBm for three channels of CDMA system application. It should not exceed +25 dBm for single channel or +19.3 dBm for three channels of TDMA system application. These power levels will guarantee the intermodulation products below -13 dBm, which is in compliance with FCC regulation. After the output power level is set correctly, connect the donor antenna cable to the "DONOR" port of the BDA. b) Uplink Gain Setting.
