The RF Power meter shows the relative transmit output power ( ). • If you press Mic [PTT] while you are outside the transmission coverage, a high pitched error beep sounds. 2 When you finish speaking, release Mic [PTT]. Note: If you continuously transmit for longer than the time specified in Menu No. 21 (default is 10 minutes) {page 62}, the internal timeout timer generates a warning beep and the transceiver stops transmitting. In this case, release Mic [PTT] and let the transceiver cool down for a while, then press Mic [PTT] again to resume transmission.

The transceiver could overheat and malfunction. ◆ Continuous transmission causes the heat sink to overheat. Never touch the heat sink when it may be hot. Note: When the transceiver overheats because of ambient high 4 temperature or continuous transmission, the protective circuit may function to lower transmit output power. SELECTING A FREQUENCY VFO MODE This is the basic mode for changing the operating frequency. To enter VFO Mode, press [VFO].
