This device complies with Part 15 of the FCC Rules. Operation is subject to the following two conditions:

(1) This device may not cause harmful interference, and

(2) This device must accept any interference received, including interference that may cause undesired operation. 2) FCC Part 15.105 :

This equipment has been tested and found to comply with the limits for a Class A digital device, pursuant to part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference when the equipment is operated in a commercial environment. This equipment generates, uses, and can radiate radio frequency energy and, if not installed and used in accordance with the instruction manual, may cause harmful interference to radio communications. Operation of this equipment in a residential area is likely to cause harmful interference in which case the user will be required to correct the interference at his expense. 3) FCC Part 15.21 :

Any changes or modifications not expressly approved by the party responsible for compliance could void the user's authority to operate this equipment. 4) FCC Part 27.5 4 Repeater User Manual SmartCell Repeater Antennas must be installed in accordance with FCC 27.50 and SRSP 518. Please note that EIRP based on antenna gain after accounting for cable loss should be less than 50 Watt (47 dBm) for Donor side. For Service side, with 3dBi gain antennas the height of the antenna above average terrain (HAAT) must not exceed 14.496 m. For different gain antennas refer to the relevant rules. 5) FCC Warning Label WARNING. This is NOT a CONSUMER device. It is designed for installation by FCC LICENSE and QUALIFIED INSTALLERS. You MUST have an FCC LICENSE or express consent of an FCC Licensee to operate this device. Unauthorized use may result in significant forfeiture penalties, including penalties in excess of $100,000 for each continuing violation. 5 Repeater User Manual SmartCell Repeater 1.1.2. IC Warning state 1) RSS-GEN, Sec. 7.1.2 (transmitters) Under Industry Canada regulations, this radio transmitter may only operate using an antenna of a type and maximum (or lesser) gain approved for the transmitter by Industry Canada. To reduce potential radio interference to other users, the antenna type and its gain should be so chosen that the equivalent isotropically radiated power (e.i.r.p.) is not more than that necessary for successful communication. Conformment la rglementation dIndustrie Canada, le prsent metteur radio peut fonctionneravec une antenne dun type et dun gain maximal (ou infrieur) approuv pour lmetteur par Industrie Canada. Dans le but de rduire les risques de brouillage radiolectrique lintention desautres utilisateurs, il faut choisir le type dantenne et son gain de sorte que la puissance isotroperayonne quivalente (p.i.r.e.) ne dpassepas lintensit ncessaire ltablissement dune communication satisfaisante. 2) RSS-GEN, Sec. 7.1.2 (detachable antennas) This radio transmitter (identify the device by certification number, or model number if Category II)has been approved by Industry Canada to operate with the antenna types listed below with the maximum permissible gain and required antenna impedance for each antenna type indicated. Antenna types not included in this list, having a gain greater than the maximum gain indicated for that type, are strictly prohibited for use with this device. 6 Repeater User Manual SmartCell Repeater Le prsent metteur radio (identifier le dispositif par son numro de certification ou son numro de modle sil fait partie du matriel de catgorie I) a t approuv par Industrie Canada pour fonctionner avec les types dantenne numrs ci-dessous et ayant un gain admissible maximal et limpdance requise pour chaque type dantenne. Les types dantenne non inclus dans cette liste,ou dont le gain est suprieur au gain maximal indiqu, sont strictement interdits pour lexploitation de lmetteur. 3) RSS-131 Section 5.3 User Manual The user manual shall contain the following information on the enhancer:

a. The nominal passband gain (dB);

b. The nominal bandwidth;

c. The rated mean output power;

d. The input and output impedances, and;

The following notice: "The Manufacturer's rated output power of this equipment is for single carrier operation. For situations when multiple carrier signals are present, the rating would have to be reduced by 3.5 dB, especially where the output signal is re-radiated and can cause interference to adjacent band users. This power reduction is to be by means of input power or gain reduction and not by an attenuator at the output of the device."

4) RF Radiation Exposure This equipment complies with RF radiation exposure limits set forth for an uncontrolled environment. This equipment should be installed and operated with a minimum distance of at least 100 cm with 15dBi antenna gain between the radiator and your body. This transmitter 7 Repeater User Manual SmartCell Repeater must not be co-located or operating in conjunction with any other antenna or transmitter. RF exposure will be addressed at time of installation and the use of higher gain antennas require larger separation distances. 5) RSS-102 RF Exposure L'antenne du donneur a une antenne 15dBi gain.Antenna doit tre install pour maintenir en tout temps un minimum de distance d'au moins 100 cm entre la source de rayonnement (antenne) et toute personne physique. Cet appareil ne doit pas tre install ou utilis en conjonction avec une autre antenne ou metteur. 1.1.3. etc. 1) Use of unauthorized antennas, cables, and/or coupling devices not conforming with ERP/EIRP and/or indoor-only restrictions is prohibited.) 2) Home/ personal use are prohibited. 8 1.2.

User may select frequency band according to the site peculiarities. After receiving a weak signal from donor antenna, the repeater improves and sends securely isolated signal out to service antenna. Amplifier unit is designed for correspondent operation with digital filter module (DFM).

(except for 2500MHz-SMT-T33) The AMP unit consists of a down and up converters, cavity filter and power amplifier

(PAU). In Downlink Path, a weak RF signal is received from Donor Antenna. Being converted from RF to IF signal, it is transferred to the DFM, where after digitalizing by DA converter, signal is filtered by FPGA. After filtering digital, signal is converted into analog RF signal with modulator. Transmit to amplifier. Desirable signal is amplified and outputted through Service Antenna. Uplink path works vice versa. 13 Repeater User Manual SmartCell Repeater

Quick GUI/Configuration Repeater User Manual SmartCell Repeater Use the following steps to commission the Repeater after all the cabling and antennas are fixed in place and the Repeater is supplied with proper electrical power. The repeater will need a good quality stable Downlink RSSI input level in the range of -85dBm to -

60dBm. 1) Connect your laptop to the repeater with a Crossover Ethernet cable. 2) Verify that your laptop has all wireless connections off and is Obtaining an IP address automatically, or is using a proper fixed IP address such as: Use the following IP address:

172.16.6.81 with a Subnet Mask of 255.255.255.252. 3) Open Internet Explorer and go to: 172.16.6.81 4) User name: admin 5) Password: admin 4.2.2. Quick Setup 1) Go to the RF Configuration page. 2) Before the Amplifier (HPA) can be turned on, set the Uplink and Downlink attenuation

(ATT) to the maximum value and click Apply. 3) Select the correct Band Block and set the ALC Downlink and Uplink Limits to the desired level and click Apply. (To adjust the Output Power, change the ALC Downlink and Uplink Limits to the desired levels). 4) To check the Repeaters status, click on the Status page. 5) To change the Repeaters gain/attenuation, adjust the Uplink and Downlink attenuation in equal amounts not more than 5dB at a time and click Apply. 28 4.3.

Troubleshooting Repeater User Manual SmartCell Repeater In case of abnormal operation, technician should diagnose abnormality via remote access or directly connecting to repeater using Ethernet cable. If technician is required to conduct repairs due to major alarm, repeater should first be powered off, and then technician should prepare the proper measurement equipment before trying to fix the problem. In most cases of major repairs, GST will simply replace the unit and conduct repairs at the appropriate facility. 4.4.1. Simple Troubleshooting Method 1) Verify LED Status, both on external LEDs as well as internal module LEDs

- Normal operation: Green light on. Alarming: Red LED on. 2) Technician should check external and internal connectors to ensure that all connections are tightly secure. These connectors should be cleaned regularly. 3) If technician thinks there is a serious problem, call after sales team for over-the-phone technical support. 1-866-9-GST-USA (1-866-947-8872) 4.4.2.
