TRANSMITTING

1To transmit, hold the microphone approximately 5 cm (2 inches) from your mouth, then press and hold Mic [PTT] and speak into the microphone in your normal tone of voice.

¥ÒÓ and the RF Power meter appears. 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.

2When 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 time-out 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.

SELECTING AN OUTPUT POWER

You can configure different power levels for transmission.

1Press [F], [MENU] and turn the Tuning control to select Menu No. 6 (TXP).

2Press [MENU] and turn the Tuning control to select ÒHÓ (high; default) or ÒLÓ (low) power.

3Press [MENU] to store the setting or any other key to cancel.

4Press any key other than [MENU] to exit Menu Mode.

Do not transmit at high output power for an extended period of time. 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 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].

Turn the Tuning control clockwise to increase the frequency and counterclockwise to decrease the frequency, or use Mic [UP]/[DWN].

¥Press and hold Mic [UP]/[DWN] to step the frequency repeatedly.
