III. OPTIONS TPL Communications’ VHF Mobile Power Amplifiers are available with several options: input, output, frequency ranges and configurations, special logos, etc., when specified at the time of order. We work closely with you, our customer, to develop products that are in complete compliance with your needs and specifications. IV. CAUTION Inspect the amplifier thoroughly upon receipt for visible damage.
V. OPERATING PRECAUTIONS CAUTION: This amplifier produces RF voltages that can cause painful and dangerous burns. Use caution! Connect and disconnect all RF connections with the drive power and DC power off. DRIVE POWER: RF power transistors, although quite rugged in most respects, are easily damage by overdrive. Be careful not to overdrive the amplifier even momentarily (before applying any drive signal please check table I for details).
EXPOSURE TO RADIO FREQUENCY ENERGY National and International Standards and Guidelines Your two-way radio, which generates and radiates radio frequency (RF) electromagnetic energy (EME), is designed to comply with the following national and international standards and guidelines regarding exposure of human beings to radio frequency electromagnetic energy: Federal Communications Commission Report and Order NO.
FOR VEHICLES WITH AN AIR BAG Do not place a portable radio or amplifier in the area over an air bag or in the air bag deployment area. Air bags inflate with great force. If a portable radio or amplifier is placed in the air bag deployment area and the air bag inflates, the radio or amplifier may be propelled with great force and cause serious injury to occupants of the vehicle.
Mobile Antenna Installation Install the vehicle antenna external to the vehicle and in accordance with: a) The requirements of the antenna manufacturer/supplier b) Instructions in the Radio Installation Manual VI. INSTALLATION The PA3-1XC amplifier installation is illustrated in figure 2. Mount the amplifier as close to the antenna as practical. Keep coaxial cable runs short, avoiding sharp bends and pinching. Avoid loose connectors at the ends of the coaxial cables.
2. Wire the DC power connector (Cinch 4 pin female) directly to the battery if possible. Do not use the present vehicle wiring. Use #12 AWG if possible and certainly no lighter than #14 AWG. To avoid a possible fire, or other possible damage, make sure a fuse or circuit breaker is installed at the battery end of the wire. Use the same size as the internal fuse listed in table I. Attach DC input wires in accordance to the diagram in figure 3.
