Important Notice! FCC RF Exposure Compliance Requirements for Occupational Use Only: The FTA-250L has been tested and complies with the Federal Communications Commission (FCC) RF exposure limits for Occupational Use/Controlled Exposure Environment. In addition, the radio complies with the following Standards and Guidelines:  FCC 96-326, Guidelines for Evaluating the Environmental Effects of Radio-Frequency Radiation.  FCC OET Bulletin 65 Edition 97-01 (1997) Supplement C, Evaluating Compliance with FCC Guidelines for Human Exposure to Radio Frequency Electromagnetic Fields.  ANSI/IEEE C95.1-1992, IEEE Standard for Safety Levels with Respect to Human Exposure to Radio Frequency Electromagnetic Fields, 3 kHz to 300 GHz.  ANSI/IEEE C95.3-1992, IEEE Recommended Practice for the Measurement of Potentially Hazardous Electromag- netic Fields - RF and Microwave.  This radio is NOT approved for use by the general population in an uncontrolled environment. This radio is restricted to occupational use, work related operations only where the radio operator must have the knowl- edge to control its RF exposure conditions.  When transmitting, hold the radio in a vertical position with its microphone 1 to 2 inches (2.5 to 5 cm) away from your mouth and keep the antenna at least 1 inch (2.5 cm) away from your head and body.  The radio must be used with a maximum operating duty cycle not exceeding 50%, in typical Push-to-Talk configurations. DO NOT transmit for more than 50% of total radio use time (50% duty cycle). Transmitting more than 50% of the time can cause FCC RF exposure compliance requirements to be exceeded. The radio is transmitting when the “ ” icon is displayed on the upper left corner of the screen of the ra- dio. You can cause the radio to transmit by pressing the PTT button.  Always use YAESU authorized accessories. NOTICE There are no user-serviceable points inside this transceiver. All service jobs must be referred to your Authorized Service Center. FTA-250L Operating Manual 1

Introduction The YAESU FTA-250L is ultra compact, stylish, solid hand-held transceivers providing communication (transmit and receive) capability on the International Aircraft Communication Band (“COM” band: 118 to 136.975 MHz). The FTA-250L includes NOAA weather band monitoring and 250 memory channels. The channel configurations can be easily reprogrammed in minutes using the optional PC Programming Software and your PC. We recommend that you read this manual in its entirety, so as to understand the many features of the FTA-250L completely. Keep this manual handy, so you may use it for reference. Congratulations!
