In order to transmit on these frequencies, you are required to have a license issued by the FCC. Application is made on FCC Forms 600 and 159. Question regarding FCC license; contact the FCC at: 1-888-CALL-FCC 1-888-225-5322 Or: http://www.fcc.gov Changes or modifications not expressly approved by Ritron, Inc. may void the user’s authority granted by the FCC to operate this radio and should not be made. To comply with FCC requirements, transmitter adjustments should be made only by or under the supervision of a person certified as technically qualified to perform transmitter maintenance and repairs in the private land mobile and fixed services as certified by an organization representative of the user of those services. Replacement of any transmitter component (crystal, semiconductor, etc.) not authorized by the FCC equipment authorization for this radio could violate FCC rules. NOTE: Use of this radio outside the country for distribution is subject to government regulations and may be prohibited. Safety and General Information RF Operational Characteristics Your radio contains a transmitter and a receiver. When it is ON, it receives and transmits radio frequency (RF) energy. The SPX-200 VHF radios operate in the frequency range of 136-174 MHz, the SPX-400 UHF radios operate in the frequency range of 400-470 MHz. When you communicate with the SPX-200, the output power level is 1-5 watts, and with the SPX-400, the output power level is 1-4 watts EXPOSURE TO RADIO FREQUENCY ENERGY The SPX Series handheld radios generate RF electromagnetic energy during transmit mode. The transmit mode is active when the PTT switch is depressed. This radio is designed for, and classified as, “Occupational Use Only”, meaning that it must be used only during the course of employment by individuals who are aware of the hazards and the ways to minimize such hazards. This series of radios is NOT intended for use by the “General Population” in an uncontrolled environment. When used as directed, this series of radios is designed to comply with the FCC’s RF exposure limits for “Occupational Use Only”. In addition, they are designed to comply with the following Standards and Guidelines: • FCC OET Bulletin 65, Edition 97-01, Supplement C, Evaluating Compliance with FCC Guidelines for Human Exposure to Radio Frequency Electromagnetic Fields. • American National Standards Institute (C95.1-1992), IEEE Standard for Safety Levels with Respect to Human Exposure to Radio Frequency Electromagnetic Fields, 3 kHz to 300 GHz. • American National Standards Institute (C95.3-1992), IEEE Recommended Practice for the Measurement of Potentially Hazardous Electromagnetic Fields-RF and Microwave. To ensure that exposure to RF electromagnetic energy is within the FCC allowable limits for occupational use, always adhere to the following guidelines: • Use only the antenna(s) available from RITRON for these models. DO NOT attempt to substitute any other antenna. DO NOT operate the radio without an antenna. • Keep talk times as short and infrequent as possible. DO NOT depress the PTT button when not actually wishing to transmit. These radios are equipped with an internal timer to limit continuous transmit times. DO NOT exceed a 50% transmit duty cycle. • When transmitting, hold the radio in front of the mouth at a distance of at least 4 inches. DO NOT hold the radio in such a manner that the antenna is next to, or touching, exposed parts of the body, especially the face or eyes while transmitting. • In belt mounted applications, when transmitting, remove the radio from the belt and hold away from the body at least 4 inches. • When using external headset accessories, hold the unit away from the body at least 4 inches while transmitting. • DO NOT allow children to operate the radio. Label (on the radio) This radio complies with the FCC RF exposure limits for Occupational Use Only. Antenna Care Use only the supplied or an approved replacement antenna. Unauthorized antennas, modifications, or attachments could damage the radio and may violate FCC regulations. Do not hold the antenna when the radio is “IN USE.” Holding the antenna affects the effective range. Two-way Radio Op…

The SPX-400 was aligned for transmitter operation on 450.125, 462.625 and 469.700 MHz (Fo) at full rated power per the tune-up procedure outlined in the Preliminary Maintenance Manual. This represents frequencies at the low, middle and high end of the SPX-400 operating frequency band. 2. Power was supplied to the SPX-400 via battery input connector J301 by a VIZ Model WP 706A power supply. The power supply was set for +7.2VDC. The SPX-400 was connected at antenna terminal ANT201 to the input of a Bird 6154 Thermaline Wattmeter, used to measure RF power of the carrier. 3. A BK Model 2704A Digital Multimeter was connected in series with pin 3 of Q101 to measure the current of Q101, the RF amplifier device.
