SYSTEM DESCRIPTION The BTS-7010 Multi-Channel Booster is a digital broadband booster designed to operate with a maximum of four simultaneous input signals. The BTS-7010 is capable of operating as a wireless video/data transmitter at a nominal power level of 5.0 watts (total average). The unit is comprised of a 64 QAM modulator (Vyyo V300 Wireless Modem Termination System), frequency agile QAM upconverter (Wavecom MA4040D) and BTS-7010 Multi-Channel Booster.

INSTALLATION PROCEDURE UNPACKING ADC certifies that upon leaving our facility, your equipment was undamaged and in proper working order. Please inspect all material upon arrival for any sign of damage. The shipping container should be examined for obvious damage indicative of rough handling. Remove the sled modules and all other material from the shipping container and check for damage: dents, large scratches, or broken connectors etc.
SYSTEM CHECK OUT AND OPERATION PROCEDURE ELECTRICAL INTERFACE PROCEDURE With the unit properly installed and adjusted in the equipment rack, the process of electrically interfacing the transmitter can begin. The following steps should be completed: INSTALL AC LINE CORD. A line cord is provided with each BTS-7010 Unit.. Insert the female connector of the line cord into the tray's AC input connector (J220).
INITIAL TURN ON PROCEDURE Before beginning routine operation, the unit should be given a step-by-step check of its functions to verify proper interface and operation. This will give the operator a chance to become familiar with the unit. The following procedure should be followed for the initial turn-on of the unit: 1. APPLY AC POWER TO BTS-7010 UNIT. Move the translator rear panel AC switch to the ON position.
NORMAL OPERATION Once the Installation and the Initial Turn-on are complete, operation is simple. With the AC ON/OFF switch in the ON position, the transmitter is activated by pressing the OPERATE (OPR) button next to the LCD display. This will now enable the transmitter. All of the green front panel operating status indicators should illuminate and the power metering should display a percentage of output power. To control the output power of the transmitter, adjust the ALC voltage (see procedure below).
SYSTEM MONITORING AND CONTROL The System Monitoring Assembly provides monitoring of system status signals through the front panel LCD display and control through five push buttons located directly below the LCD display: The Previous (PRV) and next (NXT) buttons are used to cycle through the various menus. The Up arrow (↑) is used to cycle through each of the transmitter sectors.

MAINTENANCE AND TROUBLESHOOTING Problem Identification The BTS-7010 consists of power supplies, power amplifiers, upconverters switching circuits and control circuitry. Each sled assembly contains front panel LEDs which indicate the operating status of the assembly. If an LED is Red or Amber (see Front Panel LED Indicator Table), the troubled section of the system is most likely to be in that area. The System Monitoring assembly displays various fault status conditions on a front panel LCD display.
Repair Procedures Repair of this transmitter assembly normally involves module level replacement. ADC maintains an adequate stock of replacement modules. If you have determined that a particular subassembly is defective and that it cannot be easily repaired at your facility, please contact the ADC Costumer Services Department. An effort will be made to provide a module on an exchange basis.
TROUBLESHOOTING Problem Identification The first step in solving a problem with the translator is identifying the nature and location of the problem. Since the translator consists of many different boards and modules, it is often difficult to determine which part is causing the problem. The best method of isolating the problem is to divide the booster into three discrete sections and determining if these sections are operating correctly.
