FTA-250L OperATing MAnuAL 1Important 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 congurations. 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.NOTICEThere are no user-serviceable points inside this transceiver.All service jobs must be referred to your Authorized Service Center.

FTA-250L OperATing MAnuAL 2323advanCed operatIonBattery Saver during ReceptionOne of the important features of the FTA-250L is its battery saver, which “puts the transceiver to sleep” for a time interval, periodically “waking it up” to check for activity. If somebody is talking on the channel, the FTA-250L will remain in the “awake” mode, then resume its “sleep” cycles. This feature significantly reduces battery drain.1. [MENU] à “SETUP” à “CONFIG” à “BATTERY SAVE”.2. Select the desired interval time by pressing the [◄] or [►] key, and then press the [ENT] key.OFF : Disables this function.50 % : Sleeps for 100 ms after 100 ms awake70 % : Sleeps for 250 ms after 100 ms awake80 % : Sleeps for 450 ms after 100 ms awake90 % : Sleeps for 900 ms after 100 ms awakeTip: The default setting: 50 %3. Press the PTT switch to return to normal opera-tion.Using the Headset MicrophoneIf you want to use the microphone of an aviation headset, change the assignment of microphone con-trolled with the PTT switch.1. [MENU] à “SETUP” à “COMM SETUP” à “MIC SELECT”.2. Select “EXTERNAL” by pressing the [◄] or [►] key, and then press the [ENT] key.3. Press the PTT switch to return to normal opera-tion.When an optional aviation headset is connected, the PTT switch on the transceiver will activate the head-set microphone for transmission.Note: If you nd it difcult to use the PTT switch of the transceiver, we recommend to use an after-market external PTT switch.

Select the side tone level by pressing the [◄] or [►] key, and then press the [ENT] key.The setting changes in the following order.OFF / LV 1 / LV 2 / LV 3 / MAX3. Press the PTT switch to return to normal opera-tion. To change the side tone level temporarily during the monitoring, pressing the [▲], [▼], [◄] or [►] key when pressing and holding the PTT switch.Lock FunctionThis function prevents accidental changes to the fre-quency setting and the keypad controls.1. Press and hold the LOCK key. While the FTA-250L is locked, the controls with the keys except the PTT switch, SQL key, LOCK key, the PWR/VOL knob, and the [121.5] key are dis-abled. If any of the keys is pressed, either of “KEY LOCK” will appear on the screen for 2 seconds and then the display will return to the previous screen.2. To turn the lock feature off, press and hold the LOCK key again. “UNLOCK” will appear on the screen for 2 sec-onds and then the display will return to the previ-ous screen.
