Page 5: General Safeguards
2. General Safeguards This section is written as a general guide for safe operation of the equipment and is intended for those having previous knowledge and experience with these kinds of equipment. It is not intended to contain a complete statement of all safety precautions, which should be observed by personnel using this or other electronic equipment. -
Page 6: Operating Safeguards
Operating Safeguards Load Impedance Technalogix FM equipment functions with a 50-ohm load impedances. It is imperative you maintain 50- ohm impedances throughout your system for your equipment to provide maximum power transfer to the antenna and decreased reflected power heading back towards the amplifier pallets. Failure to provide a 50-ohm path throughout the system may result in damage to your equipment. -

Products sold through, but not directly manufactured by Technalogix, carry the original manufacturer’s warranty. -
Page 11: Principle Of Operation
Power Amplifiers (IPAs) and/or final stage pallets. If multiple final pallets are required, then a splitter and combiner are also required before and after the final stages. Technalogix manufactures FM amplifiers and transmission systems suitable for 87.5 to 108.0 MHz. Custom frequencies are available upon request if you require carriers outside this range, including audio for VHF applications and other unique requirements. -
Page 12: Installation
If the equipment is damaged, a claim should be filed with the carrier once the extent of the damage is assessed. Technalogix cannot stress too strongly the importance of immediate careful inspection of the equipment and subsequent immediate filing of the necessary claims against the carrier if necessary. If possible, inspect the equipment in the presence of the delivery person. -

Page 14: Initial Hook Up
6.3. Initial Hook Up 1. Ensure that the antenna has been swept and, ideally, has a return loss of greater than 20dB (VSWR = 1.2:1). This should be done before connecting the antenna cable to the system’s output. The power amplifier’s control system allows the user to change the VSWR trip point up to a maximum level of 1.8:1, unless a custom VSWR protection system has been requested. -
Page 15: Operating Procedure
7. Operating Procedure Assuming the previous installation instructions have been completed and cautions noted, and the power amplifier is ready to receive a properly modulated RF signal, proceed with the following steps to place the system in operation. The power amplifier has been factory aligned for a specific frequency (per system specification), signal levels and optimum performance. - Page 16 At this time, Technalogix recommends that you document your measurements to use as a reference over time. The measurements can be made either from the front display, or remotely via the Remote Port (DB25), Ethernet (lower RJ45), or SNMP (lower RJ45), whose operation is explained in the Monitor and Control System sections.

Page 45: Facility Recommendations
You are apt to get better overall support if you cultivate business relationships with local suppliers Technalogix recommends that proper AC line conditioning and surge suppression be provided on the primary AC input to the power amplifier or transmitter. If DC is used as a source, a DC-DC converter is recommended to provide isolation between the supply and the load. -
Page 46: Shelter Security
The selection, routing, and length of coaxial cable are extremely important in the installation. If there is a 3 dB line loss in the cable between your unit’s output and the transmitting antenna, the unit will only deliver half power. Buy the best cable you can obtain, route it via the shortest way to the antenna, and keep it straight. -
Page 47: Heating And Cooling Requirements
The environment’s temperature will contribute greatly to the length of the power amplifier’s or transmitter’s life. Technalogix recommends that the building’s filtered air intake must have capacity for all air-flow in the building plus an additional 20%. Keep the intake below the roofline to avoid intake of solar heated air. -
Page 48: Maintenance
Maintenance If your unit employs a filter on the air inlet for the fans, the filter should be cleaned every 30 days. If the equipment is operated in a severe dust environment, the filters on the inlet fan may need to be cleaned more regularly. -
Page 49: Troubleshooting
Troubleshooting The first and most important aspect of troubleshooting anything is to be systematic. Note where you have looked and what you found. Look first for the obvious. • Make a physical inspection of the entire facility. Are all necessary connections properly made? Do you see any signs of obvious damage within the equipment? Is the AC power ‘ON’... - Page 50 Thank you for choosing Technalogix Ltd. If there is anything we can do to help in your success, please do not hesitate to contact us.
