SELECTING A FREQUENCY VFO Mode This is the basic mode for changing the operating frequency. Rotate the ENC control clockwise to increase the frequency and counterclockwise to decrease the frequency. MHz Tuning Mode If the desired operating frequency is far away from the current frequency, it is quicker to use the MHz Tuning Mode. To adjust the MHz digit: 1 Press [F]. • The MHz digit blinks. 2 Rotate the ENC control to select the desired MHz value. 3 After selecting the desired MHz value, press [F] or [ENT] to exit the MHz Tuning Mode and return to normal VFO Mode. 4 Continue adjusting the frequency as necessary, using the ENC control. TRANSMITTING/ RECEIVING 1 To transmit, hold the transceiver approximately 5 cm (2 inches) from your mouth, then press and hold [PTT] and speak into the microphone in your normal tone of voice. • The TX-RX LED lights red. 2 When you finish speaking, release [PTT]. • The TX-RX LED lights green while receiving a signal. Note: If you continuously transmit for longer than the time specified in Menu No. 19 (default is 10 minutes), the internal time-out timer generates a warning beep and the transceiver stops transmitting. In this case, release [PTT] and let the transceiver cool down for a while, then press [PTT] again to resume transmitting. 11
